INTERRELATION OF TOOTH WEAR RATES BETWEEN DRIVING AND DRIVEN GEARS

Abstract

The article reviews interrelation of wear speeds of the accelerating and decelerating gears’ teeth heads and legs, at an account of the ratio of a relative wear of the teeth depending on the number of gear teeth participating in meshing and gear ratio. Regularities of wear rate changes between gear teeth head and foot, hardened by bulk hardening, hardening by high frequency current, cementation and nitriding, in the presence and absence of abrasive particles in the working environment, when the gear ratio has increasing (accelerating) or decreasing (reducing) tendency, have been established. Hardness laws of the friction surfaces of the driven gear wheel teeth friction surfaces of the accelerating and reducing gears have been determined.
