Changing the state of the contacting surfaces of elastomers and structural steels on the example of a slewing support
Abstract
Slewing bearings are widely used in self-propelled jib cranes, naval artillery mounts, excavators, motor graders and graders, hoisting vehicles, machine tools, etc., and are designed to rotate their slewing parts relative to fixed ones, and are used in products operating with low rotation speed. The main structural elements of the devices are the geared ring of the turntable and sealing elements, which, under the influence of changing operating conditions, are subject to wear and change in the stress-strain state during operation. The article discusses changes in the state of the contacting surfaces of non-metallic materials (caprolon and rubber products) and structural steels of the elements of the slewing support, the failure of which creates an emergency, which leads to a violation of the performance of the machine as a whole.
