High temperature resistant low speed bearing

Abstract

The invention discloses a bearing with high-temperature resistance and low speed, comprising a bearing support, at least three roller shafts and a plurality of rollers clearance fitly sleeved on the roller shafts; wherein, the bearing support is fixedly arranged on a non-rotatable part of a rotary machinery; the roller shafts are arranged on the bearing support, and the roller shafts and the rotating shaft are parallel and evenly distributed around a rotating shaft; external circle of the roller is rolling fitted with the rotating shaft. The bearing with high-temperature resistance and low speed has the advantages that the bearing can work under working environment with high temperature and lower rotational speed; any lubricant is not needed; normal and long cycle of production can be maintained and production and maintenance cost are saved.

Description

technical field [0001] The invention relates to a bearing, in particular to a high temperature resistant low speed bearing. Background technique [0002] Bearing is an indispensable part of mechanical equipment. Its main function is to support the rotating parts and realize the rotational cooperation of the rotating parts relative to the fixed parts, that is, to fix the shaft so that it can only realize rotation, and to control its axial and radial direction. move. [0003] To ensure the effective and reliable operation of the bearing, there must be sufficient lubrication to prevent direct contact between the rolling elements, raceways and cage, and to prevent wear and protect the bearing surface from corrosion. In the prior art, the type and amount of lubricant in bearing design is one of the factors to be considered. The selection of appropriate lubricants and lubrication methods should be based on the specific application conditions of various bearings, which is as impo...

Problems solved by technology

[0004] In the actual production of some occasions, such as the bearing of the incinerator grate, the working environment temperature of the bearing is high and the speed is low. The lubricating oil and grease used for the bearing cannot meet the high working temperature, resulting in changes in properties , can not be lubricated normally; because there is no good lubrication, the bearing wear is intensified, and the friction generates heat accumulation. In addition, the ambient temperature is high, and the bearing is easy to lock, which greatly increases the power consumption of the power machine. Due to the bearing lock, it also increases maintenance and replacement. Difficulty, increase maintenance cost
