Rolling bearing loading apparatus with transient impact function and control method thereof

Abstract

The invention discloses a rolling bearing loading apparatus with a transient impact function and a control method thereof. The apparatus comprises two parts of an execution unit and a control unit. The execution unit comprises a loading apparatus, connecting discs, a thrust piston, an oil cylinder body, supporting seats, a lifting platform, jacking oil cylinders, and a base. The control unit comprises an electromagnetic reversing valve, an overflow valve, a pressure testing apparatus, a one-way valve, a hydraulic operated directional valve, and a high-pressure accumulator. According to the rolling bearing loading apparatus with the transient impact function and the control method thereof, a double-acting mode is adopted to accelerate the loading apparatus under the action of an oil pump and the high-pressure accumulator, so that higher impact speed and greater impact energy are generated. The rolling bearing loading apparatus can be automatically adjusted by a hydraulic control loop, and the loading process with low energy consumption, high efficiency, and high precision can be achieved. The load data in an impact process can be recorded by a pressure sensor. The rolling bearing loading apparatus with the transient impact function and the control method thereof have the characteristics of convenience and quickness.

Description

technical field [0001] The invention belongs to the technical field of rolling bearing simulation tests, in particular to a rolling bearing loading device with a transient impact function and a control method thereof. Background technique [0002] Rolling bearing is an important component of rotating machinery, and its mechanical properties have an important impact on the dynamic characteristics of the mechanical system. Complex rotor systems are the main application form of rolling bearing test technology. At present, the main problem of this technology is that it cannot fully simulate the actual operating conditions of the bearing, which seriously restricts the development of related industries, especially the aerospace industry, and brings certain resistance to the research and development of my country's mechanical equipment. In order to solve this problem, relevant scholars at home and abroad have carried out a lot of research, mostly focusing on the influence of the lo...

AI Technical Summary

Problems solved by technology

However, this device cannot simulate the dynamic behavior of rolling bearings under transient impact forces

In addition, the patent lacks a pressure testing device and cannot measure the mechanical properties during the loading process

But in fact, the impact force acts for a very short time during the entire impact process, and the device cannot accurately simulate the response state of the bearing in the actual working state.
