Abstract

In the industry, large-scale and large-body gear transmissions are widespread. For example, ball mills, intended for grinding various ores, coal and other raw materials, are equipped with open gears. They also, like all open transmissions, work under shock-cyclic contact loads. Characteristic reasons for lowering the bearing capacity are determined not only by the hardening of the tooth in its base but also by fatigue cracking of the contact surface and wear of the profile of the tooth. The key issues in the design of gear transmissions are the selection of gear material and the method of strengthening it.
