Abstract

The invention relates to a test detection device for a joint bearing, belonging to the technical field of engineering machine test equipment. The joint bearing and a connecting shaft are arranged in an inner hole of a loading bracket in an interference fit way; two ends of the connecting shaft are fixed inside a following shaft sleeve and a rotary sleeve by using an expansion sleeve; the following shaft sleeve and the rotary sleeve are arranged in inner holes of double-row conical roller bearings; the double-row conical roller bearings are arranged on bearing seats at the two ends; and the bearing seats at the two ends are fixed on a base through guide blocks. The test detection device has the advantages of novel structure, high reliability, convenience for repeated assembly and disassembly, suitability for testing bearings of different specifications and capability of detecting the friction coefficient and the service life of the joint bearing and measuring the temperature change of the joint bearing under repeated load.

Description

Technical field [0001] The invention belongs to the technical field of engineering machinery test equipment, in particular to a device for detecting and measuring the performance of joint bearings. Background technique [0002] At present, most of the domestic high-speed rail trains and military products use imported joint bearings. With the development of the national economy and the country’s support for independent brands, domestic joint bearing manufacturers need to test the reliability of joint bearings. And measurement, which requires corresponding equipment to simulate the actual working conditions to detect the performance indicators of the product, detect the friction coefficient of the joint bearing, and observe the temperature change when the joint bearing rotates at different frequencies. Summary of the invention [0003] The invention provides an articulated bearing test detection device to solve the problem that the reliability of the articulated bearing cannot be in...
