Silent carrier roller system

Abstract

The invention relates to a silent carrier roller system. The silent carrier roller system comprises bearing seats, seal assemblies and buckling parts; the bearing seats are arranged at the two ends of a carrier roller pipe body, and each bearing seat comprises a bearing seat outer wall and a bearing seat inner wall, wherein a bearing and a carrier roller shaft penetrate through the bearing seat inner wall; the seal assemblies are arranged in the bearing seats and make contact with the bearings; the buckling parts are fixed on the carrier roller shaft and attached to the seal assemblies; the surface of each bearing seat inner wall is provided with a plurality of shock absorbing ribs, so that the bearing seats are connected with the bearings in an interference fit mode. According to the silent carrier roller system, by arranging a plurality of the shock absorbing ribs on the bearing seat inner walls to achieve interference fit of the bearing seats and the bearings, the effect of correcting the coaxiality error between the bearings and the bearing seats can be achieved, it can be guaranteed that the coaxiality of the bearings and the bearing seats is high during assembly, the shock absorbing ribs can absorb impact or friction or vibration generated by operation of a carrier roller due to the machining or assembling error and effectively reduce noise generated when the bearings, the bearing seats and the carrier roller shaft are operated, therefore, the denoising and silencing effects are achieved, and the service life of the carrier roller is prolonged.

Description

technical field [0001] The invention relates to an idler, especially a silent idler system. Background technique [0002] Rollers are widely used in open-air, dusty and highly corrosive harsh environments, such as metallurgy, mining, chemical industry, grain, steel, food processing, cement, water conservancy and other industrial fields. At present, idler rollers are mainly used as auxiliary support for different types of belt conveyors required by many different types of production lines. Specifically, several idler rollers will be set on the belt transmission channel. The belt is located above the idler rollers. During the material process, the belt is supported by the idler roller to smoothly transport the material to the designated position. [0003] The existing idler rollers, the inner idler bearings and idler shafts are generally made of steel products, which need to be lubricated regularly. For the normal operation of the idler rollers, sealing devices are generally ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: for the sealing device of the existing rollers, the parts are generally tightly matched, which not only easily produces assembly errors, but also easily causes the mutual load impact of the parts during the operation of the roller, resulting in running noise, which directly affects the roller. To solve the problem of the service life of the roller, provide a silent idler system
