A kind of steel ball detection device for bearing

Abstract

The invention discloses a steel ball detection device for bearings, which comprises a mounting plate, two parallel rails are arranged above the mounting plate, the rails are fixed by a set of first fixing columns, a bin is arranged at one end of the rails, and the rails are Three first detection devices and two second detection devices are installed on the silo, one side of the silo is fixed by a set of support columns, and a through pipe is connected to the lower end of the silo. The device is provided with multiple sets of first detection devices for detecting the roundness of the sphere. The first detection device utilizes the principle that any point on the sphere is equal to the center of the sphere, and uses a distance sensor for detection, which greatly reduces the The error is increased, the detection accuracy is increased, and the experimental error caused by a single detection is effectively prevented. When the sphere moves through the corner, the sphere will flip on the track, so that every point on the sphere is detected. , which increases the accuracy of the experiment and reduces the probability of missed judgment.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a steel ball detection device for bearings. Background technique [0002] Ball bearings are mainly composed of four basic elements: ball, inner ring, outer ring and retainer, also called cage or retainer. General industrial ball bearings meet the AISI 52100 standard. The balls and rings are usually made of high-chromium steel, and the Rockwell C-scale hardness is about 61-65. The hardness of the cage is lower than that of the ball and the ring, and its material is metal (such as: medium carbon steel, aluminum alloy) or non-metal (such as: Teflon, PTFE, polymer material). Ball bearings have smaller rotational frictional resistance than journal bearings, so at the same speed, the temperature generated by friction will be lower. [0003] The bearing is a bearing equipped with spherical balls between the inner ring of the two raceways and the outer ring of which the raceways are s...

Problems solved by technology

[0006] Clearance analysis of angular contact ball bearings. For angular contact ball bearings, the clearance also determines its fatigue life. If the clearance is not selected properly, it is very easy to cause early failure of the bearing

[0007] At present, in high-precision ball bearings, the roundness of the ball and the smoothness of the surface still play a vital role. If the balls for bearings are not tested, there will be a phenomenon that the balls that are not round enough to enter the production are prone to jamming or the bearings Disintegration
