Stepped shaft type multi-dimension rolling bearing fault simulation experiment table with screw clamping

Abstract

The invention discloses a stepped shaft type multi-dimension rolling bearing fault simulation experiment table with screw clamping. One end of a multistage stepped shaft is connected with a driving motor, the other end of the multistage stepped shaft is connected with one end of a torque and rotating speed meter, the other end of the torque and rotating speed meter is connected with a magnetic powder brake, one segment of the step at the middle of the multistage stepped shaft is sleeved by an inner ring of an experiment rolling bearing, one end of a straight sleeve is abutted against an end surface of the inner ring of the experiment rolling bearing, the other end of the straight sleeve is abutted against a flange end surface of a sleeve with a flange, the other end of the sleeve with the flange is abutted against an end surface of an inner ring of a second mounted bearing, an outer ring of the experiment rolling bearing is clamped by a screw clamping device, the driving motor and a first mounted bearing are arranged on a driving end pedestal, the second mounted bearing, the torque and rotating speed meter, and the magnetic powder brake are arranged on a loading end pedestal, and the driving end pedestal, the screw clamping device and the loading end pedestal are arranged on a base bench. According to the experiment table, fault simulation experiments of the rolling bearings of various dimensions can be performed, the dismounting is convenient, and data acquisition is reliable and complete.

Description

technical field [0001] The invention relates to a rolling bearing test bench, in particular to a stepped shaft type multi-size rolling bearing failure simulation test bench clamped by a screw rod. Background technique [0002] Rolling bearing is a very important standard part in modern mechanical equipment, which supports the rotating shaft in mechanical equipment, and plays a role in reducing the friction coefficient of rotating motion and ensuring the rotation accuracy. In many cases, the operating environment of rolling bearings is high temperature, high speed or variable speed, heavy load or variable load conditions, such as high-speed trains, wind turbines, mining machinery and automobiles; in addition, rolling bearings may also run in poor lubrication, Under harsh working conditions such as foreign matter intrusion. These factors make rolling bearings prone to damage such as pitting, cracks, wear or peeling, and rolling bearing damage will eventually lead to mechanica...

Problems solved by technology

This makes most of the current rolling bearing fault simulation test benches usually only able to conduct experiments on rolling bearings of a certain specification

However, if you want to conduct experiments on rolling bearings of other specifications on these test benches, you need to make major changes to the installation mechanism of the rolling bearings, and the time and economic costs are relatively high.
