Bearing experiment table capable of applying complex load

Abstract

The invention belongs to the field of design of bearing performance testing devices, and relates to a bearing performance testing experiment table capable of applying complex loads. The device provided by the invention can realize combined application of axial, radial, torque load and dynamic and static load of the bearing, provides a design method of an experimental bearing pedestal under complexload and a design scheme of a self-centering loading device, and solves the problem that the real working condition of the bearing is difficult to simulate in the current bearing performance detection.

Description

technical field [0001] The invention belongs to the design field of bearing performance testing devices, and relates to a bearing performance testing experimental platform capable of applying complex loads. Background technique [0002] As a supporting component, bearings are widely used in rotating machinery in many industries such as aerospace, military industry, and medical treatment. In most cases, bearings will operate under the action of multiple combined loads. If the bearing’s ability to withstand a certain load Failure to meet the standard may lead to bearing failures. For example, the bearing's ability to withstand eccentric loads is insufficient, which will lead to eccentric wear and partial shedding of the bearings, and more serious problems will affect the operation of the whole machine. Therefore, the bearings that bear complex loads It is extremely important that performance is adequately tested. [0003] A number of patents and papers at home and abroad have...

Problems solved by technology

For example, the joint dynamic and static load loading device of the thrust bearing test bench (2012205749696) designed a dynamic and static combined load application device for the thrust bearing. For thrust bearings, radial load and partial load cannot be applied; Rolling bearing test bench (2008300578746) designed a bearing test bench that uses a screw to apply bearing axial and radial loads, but due to the design defects of the test bench And there is no reasonable power device, so that the test bench cannot apply dynamic load and partial load; a radial rolling bearing test bench (2017212697059) designed a radial rolling bearing test bench with a power device installed at the bottom of the test bench test device, The test bench realizes the joint application of dynamic and static loads and radial and bearing loads, but the test bench does not have an eccentric load application device, and is only suitable for radial rolling bearings, making the device not universally applicable
