Abstract

A large volume of rocks containing valuable minerals is treated at mining and processing plants in Kazakhstan. Ball mills and rod mills are used for their grinding and further processing in Balkhash, Zhezkazgan.

Ball mills with gear drive rings in the drums suffer from intense wear of the teeth due to the heavy mode of the mill operation. It thus necessitates their frequent replacement and long mill downtime. The gears of the ball mill drive experience an intense impact stress, which reduces the resource of their operation and the mill as a whole due to wear.

The article presents research on developing rational parameters of involute gearing, aimed at increasing the loading capacity of the gear as well as reducing the overall dimensions, noise, and vibration. In order to solve the set tasks, dynamic processes are simulated, modification of the teeth is proposed, and the task of designing the initial meshing contour is solved when the line of the tooth profile is slightly deviated from the involute curve of the tooth surface.

The kinematic and dynamic parameters of a tooth transmission influencing the wear resistance of teeth are found out, and also the influence of the loading capacity under conditions of stable lubrication is determined.

Because of the complexity of modifying a large diameter of the driven gear wheel, it is proposed to modify only the teeth of the driving wheel, both at their tops and legs
