Tapered roller bearing with positioning groove in outer ring end face

Abstract

The invention discloses a tapered roller bearing with a positioning groove in an outer ring end face, and belongs to the technical field of automobile parts. The tapered roller bearing mainly solves the problems of interference fit requirements of manufacturers under special mounting conditions and difficulty in mounting and dismounting large bearings and bearings which are frequently dismounted.The tapered roller bearing is mainly characterized by comprising an inner ring, an outer ring, a retainer and rolling bodies, a key groove is formed in the position where the end surface of the outerring is connected with and corresponds to the outer diameter; after the bearing and the shell are assembled, a bearing ring and a matching surface are matched through the flat key groove to perform circumferential positioning, so that the aims of accurately mounting, positioning and using the bearing and conveniently mounting and dismounting the bearing are fulfilled, and the mounting and using requirements of the manufacturers are met. The tapered roller bearing has the characteristics of simple structure, accurate positioning and convenience and quickness in mounting and dismounting, and ismainly used for front and rear axles of bridge factories and engineering trucks.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a tapered roller bearing with positioning grooves on the end face of the outer ring, which is applied to the wheel hubs of front and rear axles of engineering vehicles. Background technique [0002] The load borne by the bearing can be divided into light load, normal load and heavy load according to the size. According to the time change of the load, it can be divided into static load, variable load and impact load. According to the direction of rotation, it can be divided into rotational load and variable direction load. In some operating conditions, in addition to directional loads, there are joint loads formed by loads caused by imbalance, loads caused by vibration, loads caused by power transmission, etc., and the magnitude and direction of the force are unpredictable. [0003] When installing and using traditional tapered bearings, interference fits are used i...

AI Technical Summary

Problems solved by technology

[0004] For large bearings and bearings that need to be disassembled frequently in special working conditions, it will increase the difficulty of installation and disassembly when using conventional interference fit, and special design for bearing fit is also required

[0005] In order to avoid and eliminate the occurrence of the above situation, the present invention designs a tapered roller bearing with a positioning groove on the end surface of the outer ring, so that after it is assembled with the housing, the bearing ring and the mating surface can be positioned circumferentially through the keyway, solving complex problems. Insufficient bearing interference under working conditions will cause slippage, excessive bearing interference will cause excessive surface stress, and large bearings and frequently disassembled bearings will be difficult to install and disassemble, so as to meet the normal installation and use requirements of manufacturers
