Abstract
A tooth gearing having a resilient coating affixed to the engaging surfaces of gear teeth, the coating having a thickness and coefficient of friction such that the sliding and external friction that would occur between gear teeth not having the coating is taken up by shear deformation of the coating.
Claims13
A gearing system for transmitting mechanical power, comprising:
- first and second rigid gears supported in meshing engagement so that surfaces on at least one engaged pair of teeth oppose one another at any instant;
- and
- resilient means positioned between engaged teeth of a pair having such physical characteristics and thickness that the sliding components of motion of said teeth relative to one another cause a shear deformation of said resilient means sufficient to eliminate physical sliding motion between the engaged teeth.
