Test bench for peaking shaft type multi-specification rolling bearing clamped by electric cylinders

Abstract

The invention discloses a test bench for a peaking shaft type multi-specification rolling bearing clamped by electric cylinders. The spline shafts of a first peaking shaft and a second peaking shaft are respectively matched with the spline holes of a first sleeve shaft and a second sleeve shaft. The stepped shafts of the first peaking shaft and the second peaking shaft jack up the inner ring of a test rolling bearing. The first sleeve shaft is connected with a driving motor. The second sleeve shaft is connected with one end of a torque and speed meter. The other end of the torque and speed meter is connected with a loading motor. The extension shafts of three servo electric cylinders clamp the outer ring of the test rolling bearing. The driving motor and a first mounted bearing are installed on a driving-end base. A second mounted bearing, the torque and speed meter and the loading motor are installed on a loading-end base. The driving-end base, a ring bracket and the loading-end base are installed on a base stand. Installation of a multi-specification rolling bearing is realized. Fault simulation experiment or life and reliability test can be carried out on a multi-specification rolling bearing. Moreover, disassembly and assembly are easy, control is precise, and data acquisition is reliable and complete.

Description

technical field [0001] The invention relates to a rolling bearing test stand, in particular to a jacking shaft multi-standard rolling bearing test stand clamped by an electric cylinder. 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 mechanical equipment...

Problems solved by technology

This also makes most rolling bearing test benches usually only test rolling bearings of a certain specification.

However, if you want to test rolling bearings of other specifications on these test benches, you need to change the size of the rolling bearing installation device on it, and the time and economic costs are high.
