Improvements in Method and Means for Machining Gears
|
Michigan Tool Co. |
Detroit, Wayne County, MI |
A gear - finishing machine comprises a cutting-tool of rack form provided with spaced cutting edges along the flanks, the rack being adapted to mesh with the gear blank and to be angularly disposed in relation to the gear axis so that relative longitudinal movement of the rack over the gear is accompanied by lateral slippage between the gear and rack to cause the cutting of the gear. In Fig. 1, the cutting tool comprises a body 41 recessed longitudinally to receive a number of centrally bored cutting elements 45 which are clamped together by a bolt 52. The bottom of the recess in the cutter body is provided with lands 46 and one side of each cutter is sloped at 42 to coact with a longitudinal retaining wedge 56 which is forced downwardly and secured by a number of screws 57. The cutters are mounted between endplates 48, 49, the former having a sloping surface engaged by a wedge member 61. Each cutter has a cross section, Fig. 4, substantially of rack tooth form, and the flanks are provided with a number of cutting edges produced by forming a number of grooves 69 in the tooth surface. For gears other than involute, the profile of the cutter may be modified. Alternatively, the grooves in the cutter flanks may be diagonally arranged as shown in Fig. 5, this construction producing a gear of modified profile. The tool shown in Fig. 1 is adapted for the production of spiral gears which are first roughed out by hobbing &c., and then mounted on an arbor 65, Fig. 15, which is gradually fed downwards by a hand-wheel 70 while the tool is reciprocated on a slide 66. The lateral component of the motion between the tooth surfaces of the tool and gear causes the cutting edges of the tool to remove metal from the gear teeth until the required tooth form is reached. A brake is applied to the gear during operation. The inclination of the arbor may be adjusted to cut gears of different spiral angles. For cutting straight spur gears, the cutting elements are arranged diagonally in the cutter body, Fig. 7; the end block 76 being correspondingly formed. The cutter arbor is then arranged with its axis parallel to the flanks of the cutter teeth, the required lateral component for the machining of the teeth being obtained as before. In place of the built-up type of cutter integral cutters may be employed and in some cases the serrated teeth may be arranged round the periphery of a circular cutter. In a modification, Fig. 18, two cutters may be arranged on opposite sides of the blank and the blank may be moved laterally of the cutters by means of a screw 79. In this way the blank is moved from a cutting portion 45 of the cutters on to a parallelly - arranged burnishing portion 81, the two portions being arranged as shown in Fig. 11. One of the cutting tools is driven to rotate the gear and reciprocate the other tool and the tools are moved towards each other during operation. After the hardening operation, the plain cutting teeth may be used for a lapping operation by introducing a suitable lapping compound between the cutter and gear teeth. In another modification the cutting teeth shown in Fig. 1 may be replaced by plain burnishing or lapping teeth. In another modification, Fig. 20, a number of gears arranged on a single arbor may coact with cutters built up either of single extended blades or from a plurality of aligned cutters. In another modification, Fig. 21, a number of circular tools are arranged round a single blank, one of the cutters being driven at 87. The blank arbor is resiliently mounted and the tool 85 is moved downwards until both tools penetrate the blank to the required depth. More than two circular cutters may be arranged in a similar way round the blank and the cutters may be of the same diameter or they may be of different diameters and different pressure angles. The cutting edges of the cutters may be produced by slotting the teeth completely through, Fig. 25, or by cutting serrations, Fig. 26, which may be undercut to provide the required cutting angles. Other methods of shaping the cutting edges are described. In another modification, Fig. 30, the cutter tooth profile may be formed with a portion 99 which modifies the theoretical profile of the generated teeth as shown in Fig. 31 at 100. In a further modification of a circular type of cutter, the cutter is built up of a number of thin gear-shaped lamin[mu] 123, Fig. 33, keyed to a hub 116 and separated by spacer discs 124. The Specification as open to inspection under Sect. 91 states that roughly hobbed teeth may be produced with the addenda relieved as shown in Fig. 31 by means of a hob having teeth 104 as shown in Fig. 35 (Cancelled), wherein the true hob profile is indicated in dotted lines. The teeth of a pinion cutter for roughing out may be similarly modified. This subject-matter does not appear in the Specification as accepted. |

Abstract:
A gear-lappingmachine for finishing gears has a number of gearlike lapping-tools 25 arranged around and meshing with the work 24, the plane of the gear being at an angle to the planes of the lapping-tools so that the lap teeth have different spiral angles from the gear teeth. The bed 11 is provided with a worktable 18 which reciprocates on ways 17, and a yoke 15 of inverted U-shape extends over the table and is bolted to the bed. The work arbor is mounted between a dead centre 22 carried by a fixed headstock, and an adjustable tailstock centre 23 which is slidable by means of a rack portion 48 engaged by a hand-operated sector 47. The lapping - tools 25 which may be of the same or different diameters or with modified tooth profiles, are mounted on arbors attached to hydraulic brake mechanism (not shown) each supported in a cylinder 27 mounted on an adjustable arm 28. The brake mechanism may comprise vanes or gears which build up a pressure which is indicated on a gauge 31 and is regulated by means of an adjustable escape orifice. The brake is effective for either direction of rotation of the arbor. A scale 32 is provided to facilitate the angular adjustment of the lap axes and the laps are adjusted radially of the gear blank along ways 33 by means of a screw 34. On the upper part of the yoke, the upper tool carrier and its brake mechanism are supported on ways 41 by means of a toggle 42 operated by a handle 43. When the toggle is broken the tool is moved upwardly by a spring to facilitate the removal and substitution of the workpiece. The gear blank is positively driven by a driver 60, Fig. 10, carried by a gear 61 connected through gear 59, shaft 52, and belt gearing 53 to a countershaft 80. A motor 65 is connected by a belt to a main shaft 68 which carries gears 81, 86 connected through an idler and directly respectively with gears 83, 87 on a shaft 84 for driving this shaft in opposite directions. The gears 81, 86 are selectively locked to the main shaft by clutches 85, 88 controlled by a lever through a rod 96. The shaft 84 is geared to the counter-shaft 80 which operates the work-rotating train. The main shaft 68 is also geared to a shaft 72 connected by a belt to a shaft 102 of the reversing and stop control mechanism 74, Fig. 5. The shaft 102 carries a gear 105 connected through a planet pinion 106 to a fixed annular gear 110 and a similar gear 111 having a slightly different number of teeth. In this way a slow differential movement is imparted to the gear 111 which forms an extension of a support 113 carrying adjustable reversing cams 100, 112 and stop elements 114. The reversing cams coact with a projection on the support of the reversing clutch control rod 96 to effect the reversals at the required times as determined by the spacing of the cams. After a predetermined number of reversals one of the stop elements 114 engages an arm 121 to operate an electric switch 124 to cut off current to the driving motor. For reciprocating the table, a gear 78 driven from the main shaft drives through a gear 128, a crank disc 129 whose pin is adjusted by a screw operated by a shaft 98. The crank pin is connected by lever mechanism to the table. In lapping a straight toothed gear the tool axes may be inclined to the blank at an angle equal to the angle of the tool teeth or they may be slightly inclined from this position to relieve the side edges of the teeth. A suitable lapping compound may be delivered to the tools during operation, or, if desired, the lapping compound may be omitted and a burnishing operation effected. In another modification, gear-like tools for taking a shaving cut in the manner described in Specification 392,385, [Group XXII], may be employed. |

Lead Testing for Sprial Gears
|
Michigan Tool Co. |
Detroit, Wayne County, MI |
Abstract:
Apparatus for gauging spiral gears &c. comprises a gauging element mounted on a carriage for. movement parallel with the axis of the gear, means for supporting the gear rotatably, and frictional means for rotating the gear interdependently with the axial movements of the carriage. The table 12, mounted in guides on a pedestal 11, is moved by operating a wheel 22 which actuates bevel gear 24, 29 and a screwed shaft 25 engaging a nut 28 depending from the table. The latter carries a sine bar 36 which can be adjusted in guides on the table and set to lie at an angle corresponding to the angle of the screw &c. to be gauged. The sine bar 36 is engaged by a recess in a bracket 52 depending from a second table 13 movable on V-guides and balls at right angles to the first table 12. The table 13 has accurately formed rails 55 on which rest wheels 62 on a shaft 59 journalled in a sleeve 58 forming part of a work carrying member 17 mounted on a shaft 16 supported in bearings in a rearwardly and laterally extending portion 14 of the base 11. A gauging device 18 is formed by two dial gauges 91, the plungers of which engage opposite sides of the long arm of a feeler member 96 pivoted between arms 94. This gauge is adjustably secured to an arm 30 secured to the table 12. The shaft 59 is fitted with a socket to receive a centre 71 carried by an arm 69 which may slide in guides on the work carrier. The screw &c. to be gauged is placed between the centres 64, 71 and the feeler moved to engage the surface of a convolution, the dial being set to zero. The handle 22 is turned and this causes the slide to move and the work to rotate so that if the screw is perfect the gauge still reads zero. Modified forms of support for the gauge are described, one designed to deal with work having a sharp lead angle. U.S.A. Specification 1,898,084 is referred to. |

Improvements Relating to Gear Profile Testing Machines
|
Michigan Tool Co. |
Detroit, Wayne County, MI |
Abstract:
The machine is provided with work-holding means, gauging means movable rectilinearly tangentially to the base-circle or like datum of the work, a fixed ratio train of interconnection between the work and the gauging means, and an angularly adjustable transmitting member for compensating for difference ratios between the size of the work and the movements of the gauging means. The gear 72 is supported on a shaft 71 between an upper axially adjustable centre 23 and a lower rotatable chuck 67 journalled in the framework. The chuck can be freed from its spindle, the lower end of which carries an arcuate friction element 22 against which bears a straight bar 21 held against the element by eccentrically adjustable rollers 64. This bar moves solidly with a sine bar 18 on a carriage 15 supported on ball bearings in V-tracks 13 on the machine body, the carriage being moved by turning a hand wheel 14 having a calibrated index. The sine bar 18 is a straight bar mounted for angular adjustment on the carriage to an extent determined by the ratio between the base circle of the gear under test and the diameter of the arc of the friction element 22. Upon tracks similar to but at right angles to the carriage tracks is mounted an indicator carriage 24 acted upon by a counterpoise which holds the carriage so that a nose 26 on the latter engages the sine bar. The carriage has mounted upon it an indicator head vertically adjustable in an upstanding bracket 32 which is transversely movable by a manually-operated threaded spindle 29 upon a sub-carriage 27 longitudinally movable on the carriage engaging the sine bar. The work is set up and the sine bar adjusted angularly. The feeler 32 is then adjusted to contact with the base circle of the gear. Then, when the wheel is turned to move the sine bar carriage a given amount, the gear is rotated through a required angle and the feeler is correspondingly moved and should, if the gear is correct, still contact with the same pressure. The gauges 55 on the gauging head indicate departure from this constant pressure. |

Improvements In And Relating To Machines for Running Together Gears or Like Cooperating Parts
|
G. E. Marbaix |
, England |
Abstract:
A machine for running together gears or like co-operating parts required to operate noiselessly is provided with means for changing the direction of transmission of the load without changing the direction of rotation of the parts. In the machine shown, the gears 1, 3 to be run together are supported on shafts 2, 4, between head stocks and tail stocks 5, 7, and 9, 11 respectively, the stocks 5, 7 being mounted on a bedplate 13 and the stocks 9, 11 being mounted on a bedplate 15 which may be adjusted relatively to the bedplate 13 by means of a screw 45. A shaft 25 rotated by a reversible electric motor 101 drives through overrunning clutches 121, 123 two hollow shafts 117, 119, so arranged that for one direction of rotation of the shaft 25 the shaft 117 is driven and for the other direction the shaft 119 is driven. The shaft 117 drives through belt gearing 21 and shaft 2, and the shaft 119 drives through belt gearing 23 the shaft 4, the directions of rotation of the shafts 2, 4 remaining unchanged. The shafts 117, 119 carry brake drums 131, 133 engaged by pivoted brake arms 135, 136, mounted on shafts 141, 142. The brake arms are operated against the resistance of springs 143, 144, to apply a load to the shaft 117, 119 not clutched to the shaft 25 by a roller-carrying member 145 on a shaft 147. Heat generated by the brake drums is dissipated by ventilating ducts 132, 134 and deflectors 130. The shaft 147 is operated from a hand wheel 161 through chain and sprocket gearing. The shaft 147 may also carry an arm 173 engaging angularly spaced arms 175, 177 on the shaft 179 of a switch reversing the armature connections of the motor 101 so that the change over of the driving relations of the gears 1, 3 and the operation of the braking mechanisms are effected simultaneously. The speed of the motor may be adjusted by means of a rheostat in series with the motor. The clutches 121, 123 suitably comprise a sleeve 110 keyed to the shaft 25 carrying coiled springs 112, 114, one end of the spring 112 entering a lug 116 on the sleeve 110. Rotation of the shaft 25 in one direction tends to unwind the springs in the shaft 117 and to wind them tighter in the shaft 119 so that shaft 117 is driven. Rotation in the opposite direction causes the shaft 119 to be driven. The spring 114, which is smaller than the spring 112 effects the initial gripping action. The shaft 25 is supported in roller bearings 109 on a bedplate 113 which is flexibly secured to the frame 29 by rubber supports 100. The tail stock 11 may consist of two sections 55, 57, the section 55 carrying a rectangular rail 54 slidably engaging a recess 58 in the section 55. The engaging surfaces 59 of the sections 55, 57 are inclined so as to allow horizontal adjustment of the section 55. A vertical adjustment may be similarly effected by means of an insert 68 having an inclined surface 70. Micrometer adjustment of the sections may be effected by means of bolts 62, 76 engaging the rail 54 and insert 68 and the parts are then locked together by bolts 61, 63, 78. The tail stock 7 may be similarly constructed. |

Detroit, Wayne County, MI |
Abstract:
A cutter for use in cutting helical gears comprises an elongated member 12 of right-angled trapezoid form with a cutting end 22 conforming to the shape of the entire intercentral space between the teeth to be cut. The edge 18 of the cutter, Fig. 5, is at right angles to the sides 14, 16 and the angle A, Fig. 5, is the pitch helix angle, or, preferably, the outside helix angle of the gear to be cut. The surfaces of the end 22 also follow the work helix and the face 26 is flat and is ground normal to the helix and at a predetermined angle to the edge 24 to provide rake. The end away from the cutting edge has an inclined slot 34 adapted to be engaged by a conical member to feed the cutters to the work. In a modification, Fig. 9, the cutter consists of two parts interlocked by a projection 40.
This is the same as U. S. Patent #2,374,890. |

Improvements Relating to Machines for Forming Machine Elements Such as Gears
|
Michigan Tool Co. |
Detroit, Wayne County, MI |
Abstract:
A machine for form-cutting simultaneously all the teeth in a gear or like machine part particularly helical gears of involute form has the work mounted on a reciprocating holder while the cutters are mounted radially in a head and are fed gradually into the work and relieved therefrom on the return strokes of the work holder. The vertical machine frame 10 carries a vertically-adjustable cutter-slide 14, adjustment being effected by a screw 18. The work blank 32 is mounted against a shoulder 36 on a mandrel 34 which has a grooved upper portion to allow cutting lubricant to flow from a pipe 144 to the working point. Spacers are located between the bottom of the blank and a plate 44 secured between collars on the mandrel. The plate 44 is secured to a rotatable ram slidable in a sleeve 52 over which is located a sliding chip guard 60. A stem 62 on the ram terminates in a ball member 64 mounted in a secondary ram 70 which is reciprocated by a crankshaft 86 driven from a motor 96 through gearing 94. The stem 62 is associated with guide means for imparting the required twisting movement to the blank. For this purpose a spiral guide 101 fixed to the stem has a helical guide surface 104 coacting with complementary guides, fixed to the sleeve 52. The cutters 116 are radially mounted in spaced slots 126 in a head 128. Each cutter is of right angled trapezoid section and the slots are inclined as shown in Fig. 7 at approximately the helical angle of the gear teeth. The cutting edges are of the required involute tooth form. The outer ends of the cutters are shaped to conform to a conical member 166 and inclined slots in the cutters are engaged by a conical ring member 182 secured to the member 166. The bottom plate 132 which returns the cutters is secured to an extension 138 of the slide 14. The slide is also formed with a part 146 carrying a headretaining tube 144 which has a flexible connection 148 to a lubricant pump 152 driven by a motor 156. A supporting member 160 bolted to the part 146 is radially slotted on its under surface and interlocks with the cutter head to prevent rotation thereof. In order to feed the cutters to the work the conical member 166 is secured by nuts 176 to a feed member 174 and has a vertical movement guided by adjustable bearing pieces 184. The upper part of the member 174 terminates in a part 190 slidable in a feed plate 192 which is itself slidable on the slide 14. The plate 192 is moved downwardly in timed relation to the ram movements to feed the cutters radially inwards while the plate 190 is moved upwardly alternately with the down feed of plate 192 to relieve the cutters from the work on the non- cutting strokes of the work ram. For these purposes a cam shaft mounted in the member 192 carries a cam fed by a ratchet wheel 204 and arranged to make one revolution to complete the radial feed of the tools. The cam engages a follower secured to the carrier 14 and the member 192 is urged upwardly by springs 220. The ratchet wheel is engaged by a pawl on a rod 228. The relieving movement is produced by a cam rod 232 engaging rolls 234 on the member 190. A cross-head 226 is connected through a link 242 and other lever mechanism to the crank shaft 86. Thus at each stroke the cam is rotated one step to feed the tools gradually to the work while at the end of the cutting stroke the cam rod 232 withdraws the tools. The parts 190, 192 are locked together with the tools in cutting position during the operative strokes by a pin on the cross-head.
This is the same as U. S. Patent #2,346,867. |
