Bearing steel ball loading test bench

Abstract

The invention provides a bearing steel ball loading test bench, which can simulate the movement of a bearing steel ball between an inner ring and an outer ring and apply a load to the bearing steel ball so as to research the performance of the bearing steel ball. The test bench comprises a frame; a rotation driving mechanism; at least three rotating wheels, wherein each rotating wheel comprises awheel shaft and a friction wheel arranged on the corresponding wheel shaft in a rotation stopping mode, and the axes of the wheel shafts of the rotating wheels are parallel; three of the plurality ofrotating wheels are arranged in a manner that respective rotating centers correspond to three vertexes of the triangle to form a test wheel set. A loading mechanism can drive the rotating wheel to apply a load to the bearing steel ball to be tested in the radial direction, and at least one loading mechanism is rotationally mounted at the output end of the loading mechanism; two of the three rotating wheels of the test wheel set are driving wheels driven by a rotary driving mechanism to rotate, and the other one is a driven wheel; when the two driving wheels rotate, the to-be-tested bearing steel balls in the placing space can be driven to roll so as to drive the driven wheels to rotate.

Description

technical field [0001] The invention relates to a bearing steel ball loading test bench. Background technique [0002] Rolling bearings are one of the widely used components in modern machines, which rely on the rolling contact between the main elements to support the rotating parts. Most of the rolling bearings in the prior art have been standardized, mainly including an inner ring, an outer ring, rolling elements and a cage, and the rolling elements correspond to the inner ring and the outer ring to form a friction pair in the rolling bearing. When the rolling element is working, it will slide and roll relative to the inner ring and the outer ring at the same time. The magnitude and direction of the friction force on the rolling element are complex and changeable. In order to ensure the service life and reliability of the rolling element and rolling bearing, technicians will In the research and development stage, various friction and wear properties of the rolling element...

Problems solved by technology

[0003] Most of the testing machines used by technicians at this stage are to test and study the entire bearing under different speeds, loads, ambient temperatures or lubrication conditions. Due to the complexity of the force during work and the uncertainty of the trajectory of the rolling elements, it is difficult to determine what caused the damage to the rolling elements, so it is also impossible to determine whether the bearing material itself used to make the rolling elements has defects
