Sliding bearing of roller presser

Abstract

The invention discloses a bearing which is used for a cement mechanical roller presser and roller press wheels of a mine crusher by taking the place of a double row spherical roller bearing adopted in original equipment. Using zinc-based alloy ZA303 as bearing material, the bearing enhances the carrying capacity greatly while keeping aligning and other service performances in original equipment due to the employment of a rolling bearing, thus meeting the demand of using the equipment to a maximal extent and gaining the exchange performance of original design. According to the invention, the problem about the carrying capacity of the bearing is settled and the service life of the bearing is prolonged in order to improve the performance of the equipment; the application of such a bearing can increase the productivity of the equipment, leading such type of equipment to large scale; the maintenance cost for the equipment is remarkably lowered. With this sliding bearing, the economical benefit can be enhanced prominently.

Description

Technical field: [0001] The bearing of the present invention is applied to large-scale equipment with low speed and heavy load on cement machinery and mining machinery, and is mainly used for the bearing on the pressure roller of a roller press. Background technique: [0002] At present, the bearings used on the roller press rollers used in cement equipment are self-aligning roller bearings such as figure 1 As shown, due to the great pressure of the pressure roller on the bearing when the equipment is working, the contact limit that the bearing can withstand exceeds the design bearing capacity of the bearing, so that the contact fatigue damage of the bearing occurs prematurely, and the service life of the bearing is shortened. A large reduction directly affects the overall performance of the equipment, and is limited by the processing capacity of rolling bearings, which also limits the increase in production and the development of large-scale equipment.

[0002] At present, the bearings used on the roller press rollers used in cement equipment are self-aligning roller bearings such as figure 1 As shown, due to the great pressure of the pressure roller on the bearing when the equipment is working, the contact limit that the bearing can withstand exceeds the design bearing capacity of the bearing, so that the contact fatigue damage of the bearing occurs prematurely, and the service life of the bearing is shortened. It is greatly reduced, which directly affects the overall performance of the equipment, and is limited by the processing capacity of rolling bearings, which also limits the increase in production and the development of large-scale equipment.
