Self-acting Wheel Tooth Cleaning Machine. — This machine (fig. 128A) is constructed to clean teeth of spur wheels and pinions and the teeth of straight worm wheels by means of an emery wheel. It is a most important labour and file saving machine, as it cleans effectually from 1000 to 1500 teeth per hour without requiring skilled labour, the machine being self-acting; and the work is much better done than by hand filing, the teeth being left quite free from irregularities. The machine will take in wheels from 2¼ inches to 24 inches diameter, and up to 4 inches depth and ¾ pitch.
The wheel to be cleaned rotates upon a stud at the top of the rising and falling ram, which works in long V slides; the wheel is held in position during the grinding by means of a spring pawl, each tooth space being cleaned by the emery wheel in both the upward and downward movement, and the spur wheel is fed round tooth by tooth by means of a ratchet pawl. This feed can be adjusted to suit any pitch of tooth up to I inch, and is obtained by merely adjusting a screw, which on the rising and falling of the ram comes in contact with the table beneath it and thereby operates the pawl. The balance weights are varied according to the weight of wheel being cleaned. |
