Bearing steel ball test bench

Abstract

The invention provides a bearing steel ball test bench, which can be matched with a bearing steel ball to simulate the movement of the bearing steel ball between an inner ring and an outer ring, and provides a movement model for technicians to research the performance of the bearing steel ball. The test bench comprises a frame; a rotation driving mechanism; a friction pair which comprises at leastthree rotating wheels, wherein each rotating wheel comprises a wheel shaft and a friction wheel arranged on the corresponding wheel shaft in a rotation stopping mode, and the axes of the wheel shaftsof the rotating wheels are parallel. Three of the plurality of rotating wheels are arranged in a manner that respective rotating centers correspond to three vertexes of the triangle to form a test wheel set; the three rotating wheels form a test wheel set; at least one friction wheel is axially and adjustably installed on the corresponding wheel shaft, and / or at least one wheel shaft is axially and adjustably installed on the rack, so the friction wheel on the friction wheel can axially deviate relative to the friction wheels on other rotating wheels, and the contact position of the bearing steel ball to be tested and the rotating wheels is changed.

Description

technical field [0001] The invention relates to a test bench for bearing steel balls. 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, the performance of the rolling elements is tested and evaluate...

AI Technical Summary

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
