A Ball Bearing Using Friction to Eliminate Pitting

Abstract

The invention relates to the technical field of bearings, and discloses a ball bearing that uses friction to eliminate pitting corrosion. It includes a base, a ball groove is movably connected to the interior of the base, and an induction spring is movably connected to the interior of the ball groove. The end of the spring away from the ball groove is fixedly connected to a support plate. The end of the support plate away from the induction spring is movably connected to an oil pipe through an adjusting spring. A hollow channel is fixedly connected to the lower part of the support plate between the symmetrical oil pipes. Under the action of extrusion force, it enters the hollow channel and is sucked into the inside of the scraper through the threaded tube. When the threaded tube is stretched and continues to approach the ball surface, the lubricating oil also flows out from the oil outlet hole, and each ball surface There is a corresponding scraper, and the lubrication work takes place in the ball groove, and due to the high rolling friction heat in the ball groove, the water will be evaporated and impurities will remain inside, thus achieving the effect of lubrication without causing pitting corrosion.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a ball bearing which uses friction to eliminate pitting. Background technique [0002] The ball bearing is a kind of rolling bearing. The spherical alloy steel ball is installed in the middle of the inner steel ring and the outer steel ring to reduce the friction force in the process of power transmission and improve the transmission efficiency of mechanical power by rolling. Ball bearings cannot withstand large heavy loads and are more common in light industrial machinery. [0003] With the continuous advancement of technology, ball bearings are used in more and more equipment. When the rolling bearings are used for a period of time, pitting will appear. The weight of the bearing, and the material made of the bearing also has a certain life span, and may even have problems such as poor quality. When a certain number of uses is reached, the stress will change those problematic ...

AI Technical Summary

Problems solved by technology

[0006] 1. By placing the balls in the ball grooves, the balls and the inner and outer rings are in contact with each other, and pitting corrosion will occur after one end of use. Because the balls have to bear a considerable weight, the material of the bearing also has a certain life span, and it may even In case of problems such as poor quality, when a certain number of uses is reached, the stress will change those problematic contact surfaces, resulting in fish scale-like fatigue peeling points in some parts. If the balls are not treated at this time and continue to be used, it will cause Grooves appear on the surface of the ball and the contact surface is no longer uniform. The weight of the ball is transmitted to the induction spring, and the induction spring on both sides of the ball groove undergoes different elastic deformation due to uneven force. This deformation squeezes or stretches the adjustment spring. , to drive the threaded pipe in the elimination mechanism away from or close to the ball. Because the threaded pipe has a certain degree of elasticity, when the threaded pipe moves, it will drive the scraper on its surface to move. When the scraper contacts the ball, it can scratch the surface. , so that the surface of the ball can restore its designed working characteristics, thereby achieving the effect of eliminating pitting; because the induction spring is connected with the outer base layer and the inner base layer of the bearing, when the ball is scratched and becomes smaller, the gap between the bases The gap is also reduced to re-engage the ball
