Waterproof and dustproof bearing block

Abstract

The invention discloses a waterproof and dustproof bearing block. The waterproof and dustproof bearing block comprises a base; a first base body and a second base body are arranged above the base; thebase, the first base body and the second base body are matched with one another to form a bearing cavity; a buffer body is arranged in the bearing cavity; a bearing sleeve is arranged in the buffer body; the bearing sleeve is internally provided with a bearing hole; positioning blocks are arranged at the positions, located under the first base body and the second base body respectively, of the upper end of the base; the lower end of the first baset body and the lower end of the second base body are provided with positioning grooves; guide columns are arranged at the positions, at the inner sides of the positioning blocks, of the lower ends of the first base body and the second base body; the positions, right below the guide columns, of the upper surface of the base are provided with guidegrooves; compression springs are arranged in the guide grooves; a sealing plate is arranged on the same side of the first base body and the second base body; a sealing ring is arranged between the sealing plate and the bearing sleeve; and the sealing plate is fixedly connected to the first base body and the second base body through self-locking bolts. According to the waterproof and dustproof bearing block, the stable working environment can be provided for a bearing, and the waterproof and dustproof effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of bearing accessories, in particular to a waterproof and dustproof bearing seat. Background technique [0002] Bearings are widely used in machinery and equipment. They are generally installed on the equipment through bearing seats during installation, and play a very important role in transmission. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is often called the bearing seat. Since a bearing can choose different bearing seats, and a bearing seat can choose different types of bearings at the same time, there are many varieties of bearing seats. [0003] The existing bearing seat not only has large manufacturing errors, but also has troublesome installation and high cost, and the concentricity and sealing performance after installation are not high, which leads to the occurrence of bearing seizure, water ingress a...

AI Technical Summary

Problems solved by technology

[0003] The existing bearing seat not only has large manufacturing errors, but also has troublesome installation and high cost, and the concentricity and sealing performance after installation are not high, which leads to the occurrence of bearing seizure, water ingress and dust ingress when the equipment is running, resulting in The operating load of the bearing increases and the bearing is damaged, which not only increases energy consumption, but also reduces the working performance of the roller
