Abstract
It is shown that wear of the active surfaces of the teeth of gears and wheels is the main factor affecting the resource of traction gears of motor-car rolling stock. Modern approaches to the experimental determination of the degrees of wear of gears and wheels of traction gears in operation are contemplated, suggesting control of the value of the division chord. In order to ensure the permissible value of the lateral clearance in the transmission, it is proposed to consider the change in their thickness for constant chords as a parameter of the wear control of the teeth. Permissible values of the variation of these parameters are given, at which acceptable values of the lateral clearance in the meshing of traction gears are provided. Features of the proposed approach are considered using the example of traction gear transmission of ER2 series.
