Means for Generating and Cutting Irregular Gears
|

Wright, Brown, Quinby & May - patent attorneys
The present invention relates to the art of generating and cutting teeth on irregular gears, by which I mean gears having teeth arranged on a pitch line which is otherwise than concentric .with the axis about which either the- gear is designed to rotate or pinion meshing with the gear is designed to revolve. In my application for patent, Serial Number 858,192 filed August 22. 1914, I have illustrated a means for generating and cutting the teeth of such a gear wherein the gear is held by a floating holder and is given a movement, relatively to a tooth-generating cutter during the generating and cutting operation, which is similar to the relative movement between the gear and the pinion with which it is designed to mesh. The apparatus and means which form the subject of the present invention are of the same general nature as those shown in my application aforesaid, but possess modifications and refinements having for their object to accomplish the desired end with less mechanical resistance and with possibly greater accuracy.
Briefly stated the principal object of the present invention is to provide a means for so moving an irregular gear blank transitively and. revolubly, in connection with generating motion of a gear-shaped planing cutter, or other cutter capable of cutting gear teeth of the desired form, during, the editing operation as to produce exactly the same relative movements between the blank the axis of the blank, as take place between the gear and the standard pinion with which it is designed to run in mesh, and to effect this movement in a positive manner and with the minimum of motional or other resistance. The particular gears of which the teeth are to be generated and cut by the present apparatus include an internal irregular gear of four equal and symmetrically arranged lobes, and an external gear of generally elliptical shape and of smaller area than the space surrounded by the teeth of the internal gear; which is placed in such space, and meshes with a number of floating pinions, which latter also mesh with the internal gear and are adapted to have a planetary motion when either the external gear or the internal gear is rotated relatively to the other. One form of the moans which I have adopted and desire to protect in the present application for giving the desired movements to the gear blank consists of a set of master gears and pinions, to one of which master gears the blank is connected, and of which one of the pinions is used as the driver for giving the generating movement to the gear being cut, in connection with a cutter which may be of any sort capable of generating the forms of gear teeth at the same time that it cuts them, by a combination of relative movements between the cutter and the work piece. One, form of such a cutter, here illustrated, has peripheral projections shaped similarly to the teeth of a spur gear and arranged on a pitch line approximately equal in diameter to the pitch, line of such driving pinion. Other forms of means for the same purpose herein illustrated comprise co-acting elements connected with the master gear and the table on which the work holder is supported for positively shifting the work holder when receding portions of the pitch line of the master gear approach the driving pinion. Essentially the same means, with minor variations adapted to the particular work in hand, may be provided and arranged for cutting any shape or character of internal or external irregular gear, wherefore the particular description, which follows of the embodiment of such means adapted to a particular purpose is not to be taken as limiting the present invention to the particular mechanism described, or otherwise, except in accordance with the appended claims.

High Speed Gear Generating Machine
|
Edwin R. Fellows |
Springfield, Windsor County, VT |
Wright, Brown, Quinby & May - patent attorneys
This invention relates to machines adapted to cut gears at high speed, with utilization of the principle disclosed in prior patents secured by me of cutting grooves in the face of a gear blank by a gear-shaped planing cutter, and generating in the sides of such grooves the correct curves of gear teeth by giving simultaneous rotary movements to the cutter and gear blank of the same character as the movements of a pair of intermeshing conjugate gears. More particularly, the invention is an improvement on the type of high-speed gear shaper disclosed in my pending application, Serial Number 351,126, filed January 13, 1920. The invention has the same objects as those set forth in the aforesaid application, and the further object of adapting the high speed type of gear-generating machine to a wider range of work, by enabling a single machine of a given size to turn out so finished work of a wider range of sizes than is possible with the machine illustrated in the aforesaid application. These further objects are accomplished by a novel mode of adjusting and feeding the cutter for depth of cut, and a new and improved mode of backing off the work during the return strokes of the cutter, and of holding the work in position to be cut during the cutting strokes of the cutter.

High Speed Gear Generating Machine

Wright, Brown, Quinby & May - patent attorneys
This invention relates to machines for generating and cutting gears of the spur type, by the action of a planing cutter which is, itself, shaped like a spur gear; and is more particularly concerned with machines of this class which are designed and adapted to operate at high speeds. In my prior Patents No. 1,478,472, dated December 25, 1923, and No. 1,463,806, dated August 7, 1923, I have disclosed gear generating or shaping machines which are capable of operating efficiently and with the desired accuracy at speeds several times greater than previously employed. In producing the invention, which I am now about to describe, my principal object has been to increase still further the speed of operation of such machines. I have accomplished this object and attained a speed of operation from seventy-five to one hundred percent greater than that which I have accomplished by the machines disclosed in the above identified patents at the same time without causing objectionable vibration as a consequence of such increased speed, by making the reciprocating parts lighter and introducing other improvements, by which the use of such lighter parts is made possible with the preservation of the high quality of accuracy which has been a characteristic of the machines produced according to my inventions, and has become an essential in the gearing art.

Cutter Relieving Means For Shaping Machines
|
Edward W. Miller |
Springfield, Windsor County, VT |
Claim:
The present invention relates to gear shaping machines and equivalent machine tools of the type in which a cutter is carried by a reciprocative and rotatable spindle and is caused to act on the workpiece by endwise movements of the spindle in one direction, and is returned, without performing any cutting action, by endwise movements of the spindle in the opposite direction. It is more particularly concerned with means or provisions for relieving the cutter, that is, effecting a relative separation between the cutter and work piece, after each cutting stroke so that it will not rub on the workpiece during the return stroke, and replacing it in the line of cutting travel before each cutting stroke. Its object is to reduce to the minimum the total mass of the parts needing to be thus displaced in order to relieve the cutter and restore the working relationship between the cutter and work, to effect the movements of relief and restoration quickly and efficiently with the minimum of shock and vibration, and to control, and alter as needed for work pieces of different types, the direction in which the relief movements take place. |
