Bearing working condition simulation test bench

Abstract

The invention provides a bearing working condition simulation test bench which comprises a main test shield body, a main test drive, an auxiliary test shield body, a flange plate, a radial oil cylinder, an axial oil cylinder and a supporting base. The main test shield body is installed on the supporting base, the main test bearing is installed on the main test shield body and fixedly connected with the outer ring of the main test bearing, one end of the inner ring of the main test bearing is connected with the main test drive, and the other end of the inner ring of the main test bearing is connected with one end of the flange plate. The accompanying shield body is provided with an accompanying bearing and is fixedly connected with an outer ring of the accompanying bearing; one end of an inner ring of the accompanying bearing is connected with the other end of the flange plate; the two ends of the radial oil cylinder are fixedly connected with the accompanying shield body and the supporting base respectively. The two ends of the axial oil cylinder are fixedly connected with the main test shield body and the auxiliary test shield body respectively. Simulation experiments of the bearing working under different working conditions are achieved, the real-time state of the bearing in the test process is monitored, application parameters capable of guiding engineering design are obtained, and the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to a bearing operating condition simulation test bench, which belongs to the technical field of bearing performance testing equipment. Background technique [0002] The bearings in the main body of the roadheader are low-speed and heavy-duty bearings used in the cutter head drive system. During the excavation process, the rolling elements and the raceway surfaces of the inner and outer rings are prone to fatigue damage failure or wear failure. The damaged bearing needs to be hoisted out from the excavation shaft above the roadheader for replacement. The construction is difficult and will bring immeasurable losses to the project. The life and reliability of the bearing directly affect the construction safety of the roadheader, and it also restricts the construction of the roadheader. important factor in service life. [0003] The bearing working condition simulation test bench is a device platform for simulating the state monitori...

AI Technical Summary

Problems solved by technology

However, in the prior art, the bearing test bench is mostly designed as a scale test bench, which cannot completely simulate the actual working conditions of the bearing. At the same time, the load capacity of the test bench is relatively weak, and the bearing specifications to be tested are small
