What reading level is Worm Gearing book?
To quickly assess the difficulty of the text, read a short excerpt:
Number of Flutes in Hobs The number of flutes that should be provided in the hob is a point on which very little is said, various authorities differing widely. Where the hob is to be used in an automatic hobbing machine in which the hob and blank are positively geared together, the number of flutes may be a comparatively small number as compared with a hob that is to be used in connection with ordinary processes of hob- bing worm gears. In the process in which the previously gashed worm-gear bl...ank is swung loosely on centers and revolved by the hob as the latter rotates, the hob should have a larger number of flutes.
A rule that checks up well with present practice is as follows: To find the number of flutes in a hoi), multiply the diameter of the hoi by three, and divide by twice the circular pitch.
The above rule gives suitable results on hobs for general purposes.
