Sliding bearing testing machine

Abstract

The invention relates to a sliding bearing testing machine which comprises a single testing machine set, a torque sensor, a driving motor, a temperature sensor and an acceleration sensor. The single testing machine set comprises a base, a rack, a hydraulic cylinder, a force measurement sensor, a loading mechanism and a work shaft, the upper face of the base is fixedly connected with the rack, the lower face of a rack cross beam is fixedly connected with the hydraulic cylinder, the force measurement sensor is arranged at the front end of a piston rod of the hydraulic cylinder, the work shaft is connected in a testing bearing component, the upper end of the testing bearing component is connected with the loading mechanism, the temperature sensor and the acceleration sensor are arranged on the two sides of the testing bearing component respectively, and one end of the work shaft is connected with the driving motor through the torque sensor and a coupling. The sliding bearing testing machine can provide the design bearing load of a sliding bearing to assess the actual work capacity, operation stability, vibration resisting performance, long indexes and other parameters of the sliding bearing. The testing machine can carry out an independent bearing test, and can achieve the synchronous test of multiple bearings and the performance comparison test of different bearings through the multi-set connection of a system.

Description

technical field [0001] The invention relates to a sliding bearing testing machine, in particular to a sliding bearing testing device capable of simulating actual working conditions. Background technique [0002] Sliding bearings have the advantages of strong bearing capacity, stable operation, good shock resistance, and long life, so they can be seen in everything from small household appliances to large steel rolling production lines. Sliding bearing testing machine is the basic test equipment for analyzing the bearing mechanism of sliding bearings, and is an important practical basis for analyzing and studying the lubrication characteristics of bearings and carrying out innovative designs. As the carrier of sliding bearing tests, sliding bearing testing machines are widely used in teaching, scientific research and production departments, and become the key to the research and manufacturing level of sliding bearings in my country. Most of the traditional sliding bearing te...

AI Technical Summary

Problems solved by technology

Most of the traditional sliding bearing test benches are mechanical, mainly manual experiments, not to mention low efficiency, it is difficult to complete experiments with high precision

Some test benches appearing on the market in recent years have been enhanced in performance and function due to the combination of modern computer technology, but from the perspective of research and design, their research is insufficient, and it is difficult to realize the experiment or test The transformation from the demonstration and verification type to the comprehensive research type cannot meet the needs of cultivating high-quality research talents in my country and the needs of improving the design and manufacturing level of sliding bearings
