Chuck clamping type multi-specification rolling bearing fault simulation experiment platform mounted on basis of stepped shaft

Abstract

The invention discloses a chuck-clamping multi-standard rolling bearing fault simulation test bench installed on the basis of stepped shafts. One end of the multi-level stepped shaft is connected to a driving motor, the other end is connected to one end of a torque tachometer, and the other end of the torque tachometer is connected. Connected with the loading motor; the inner ring of the experimental rolling bearing is sleeved on a step in the middle of the multi-step stepped shaft, one end of the straight sleeve withstands the end face of the inner ring of the experimental rolling bearing, and the other end withstands the flange end face of the flanged sleeve; three-jaw clamp The jaws of the disk clamp the outer ring of the experimental rolling bearing. The driving motor and the first bearing with a seat are installed on the base of the driving end. The second bearing with a seat, the torque tachometer and the loading motor are installed on the base of the loading end. The base of the driving end , the chuck frame and the loading end base are installed on the base table. The invention realizes the installation of multi-standard rolling bearings, can carry out failure simulation experiments on multi-standard rolling bearings, is convenient for disassembly and assembly, and has reliable and complete data collection.

Description

technical field [0001] The invention relates to a rolling bearing test bench, in particular to a chuck clamping multi-standard rolling bearing failure simulation test bench based on stepped shaft installation. 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...

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 change the size of the rolling bearing installation mechanism on it, and the time and economic costs are relatively high.
