Bearing for textile machinery

Abstract

The invention discloses a bearing for textile machinery, which relates to the field of textile machinery; the key points of the technical solution are: an inner ring (1), an outer ring, balls and a cage, and sealing the assembly space between the inner ring and the outer ring There are two ring-shaped sealing covers, and two sealing covers are symmetrically located on both sides of the inner ring and the outer ring, and the two sealing covers are oppositely arranged; the sealing cover is made of foam plastic; the sealing cover includes The first cover and the second cover, the first cover and the second cover can be rotated and sealed; the outer peripheral side wall of the first cover and the middle part of the inner peripheral side wall of the second cover are provided with a sealing ring; The first cover and the second cover are sealed by lubricating oil. The invention achieves the effect of preventing dust from entering the bearing by dividing the sealing cover into two rotatable parts and fixing them with the inner ring and the outer ring of the bearing respectively.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a bearing for textile machinery. Background technique [0002] Rolling bearings are an important basic component widely used in the machinery industry. Whether it is aircraft, automobiles, ships, machine tools, household appliances, IT machines, etc., wherever there is rotation, bearings are inseparable. As an important part of the bearing, the bearing seal mainly plays the role of sealing, preventing the oil leakage inside the bearing and the entry of foreign matter from the outside, and maintaining and extending the service performance of the bearing. [0003] A general bearing includes an inner ring, an outer ring, balls, a cage and a sealing cover. Sealing rings are installed on the inner and outer side walls of the sealing cover. There are three extended lips on the lower edge of the outer edge of the sealing cover. There is a sealing groove, and the lip of the sealing ring...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the prior art is that since the sealing ring is fixed on the outer ring on one side, and there is a large gap between the other side and the inner ring, after the bearing has been used for a period of time, especially in the textile industry, Due to the need for long-term continuous work, the temperature of the lubricating oil in the bearing rises, the molecular gap becomes larger, and the structure is loose, resulting in reduced adhesion and increased fluidity, which is very easy to flow out from the gap between the sealing ring and the inner ring. The lubricating effect is reduced; at the same time, external dust, moisture, etc. can easily enter the bearing through the gap between the sealing ring and the inner ring, affecting the rotation of the ball
