The invention provides a bearing bush performance testing machine and a testing method. The bearing bush performance testing machine comprises a mechanical system, a hydraulic loading system, a lubricating system, a signal testing system and a control system; the mechanical system comprises a test main shaft (7), a main shaft rotating device, a test bearing bush (11), a test load loading device and an inclination angle loading device, wherein the test main shaft (7) is arranged on the main shaft rotating device; the test bearing bush (11) is installed on the test load loading device; the testmain shaft (7) and the test bearing bush (11) form a rotary friction pair; the inclination angle loading device can enable the test bearing bush (11) to be inclined relative to the test main shaft (7); the hydraulic loading system can be used for performing upward loading on the test bearing bush (11); and the lubricating system can lubricate the test bearing bush (11). The use performance of thebearing bush under different axis inclination angles can be accurately tested, the operation is simple, and the measuring precision is high.
Description
technical field [0001] The invention relates to the technical field of bearing pad testing machines, in particular to a bearing pad performance testing machine and a testing method, in particular to a testing machine and a testing method for testing the performance of bearing pads by installation inclination angles. Background technique [0002] As a key basic part in industrial applications, bearing pads play the role of support and power transmission during the operation of equipment, and their performance directly determines the reliability and safety of equipment operation. Most of the domestic and foreign test benches for testing the performance of bearing pads focus on the bearing capacity and other lubrication characteristics of the bearing pad under the condition of the axis being centered, without considering the influence of the axis tilt on the performance of the bearing pad. In the process of actual operation, axis deviation is a common phenomenon. There are man...
