Multi-dimensional automatic loading fatigue testing machine for bearing

Abstract

The invention relates to a multi-dimensional automatic loading fatigue testing machine for a bearing. A tested bearing loading device is arranged on a test bench; a bearing seat used for installing atested bearing is arranged in the tested bearing loading device, two ends of the tested bearing loading device are connected with a servo electric cylinder radial loading mechanism, one side of the tested bearing loading device is connected with the servo electric cylinder axial loading mechanism, the other side of the tested bearing loading device is connected with a tested bearing driving mechanism, tension and pressure sensors are respectively arranged in the servo electric cylinder radial loading mechanism and the servo electric cylinder axial loading mechanism, and a torque sensor and anangle sensor are arranged in the tested bearing driving mechanism; the tension-pressure sensor, the torque sensor and the angle sensor are connected with a measurement and control instrument; the measurement and control instrument is connected with the servo electric cylinder radial loading mechanism, the servo electric cylinder axial loading mechanism and the tested bearing driving mechanism through drivers and is used for controlling and driving the loading of the servo electric cylinder radial loading mechanism and the servo electric cylinder axial loading mechanism, realizing automatic axial and radial loading and various load loading forms, and automatically reading a load spectrum and various load test information.

Description

technical field [0001] The invention relates to a fatigue testing machine, in particular to a bearing loading fatigue testing machine. Background technique [0002] Bearing loading fatigue testing machine refers to the equipment for fatigue life test under load. The fatigue life test results can reveal the quality level of bearing mechanism design, manufacturing process, material and lubrication, etc. It is an important indicator for comprehensive evaluation of bearing product quality. [0003] The development of bearing loading fatigue testing machine in our country started relatively late. The earliest test platform was imported from the Soviet Union. Most of them were loaded in radial and axial directions. Running for a long time will cause oil leakage and pollute the environment. Therefore, with the continuous improvement of bearing precision and reliability requirements, the performance of existing bearing loading fatigue testing machines cannot fully meet the requirem...

[0003] The development of bearing loading fatigue testing machine in our country started relatively late. The earliest test platform was imported from the Soviet Union. Most of them were loaded in radial and axial directions. Running for a long time will cause oil leakage and pollute the environment

Therefore, with the continuous improvement of bearing precision and reliability requirements, the performance of existing bearing loading fatigue testing machines cannot fully meet the requirements.
