Problems solved by technology

The disadvantages of this structure cage are: the design structure is not reasonable enough, the cover and the seat are riveted by high-frequency heating, due to the process shape error of the cover and seat, the parallelism will be affected during high-speed operation, and it cannot meet the low vibration required by precision equipment , low noise requirements; at the same time, the heat dissipation is poor, and the oil film is not easy to form, so it cannot guarantee the good lubrication of the product during high-speed operation; in addition, the manufacturing process is poor, the process is many, the cost is high, and the bearing assembly efficiency is low

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] refer to Figure 1 to Figure 4 As shown, a cylindrical roller bearing with an integrated solid copper cage of the present invention includes an inner ring, an outer ring, a copper cage and rolling elements. The copper cage is composed of an inner edge 8, an outer edge 7 and several pocket beams 5. integrated structure. Wherein, the inner edge 8 and the outer edge 7 are connected by a pocket crossbeam 5, and the middle of the pocket crossbeam 5 both sides is a pocket wall 3, and its two sides are arc surfaces. The outer end of the pocket wall 3 is provided with an outer locking arc 4 , and the inner end is provided with an inner locking arc 2 . An inner lock entrance β angle 1 is arranged on the inner side of the arc amount 2 of the inner lock opening. The outer locking arc amount 4 of the pocket crossbeam 5, the inner locking arc amount 2 and the pocket wall ...

Abstract

The invention relates to a cylindrical roller bearing with an integrated solid copper retainer, and belongs to the technical field of cylindrical roller bearings. The cylindrical roller bearing mainlysolves the problem that high-speed operation parallelism is affected due to the fact that an existing copper retainer which is formed by riveting a cover and a base through high-frequency heating hasa process shape position error. The cylindrical roller bearing is mainly characterized by comprising an inner ring, an outer ring, the copper retainer and a rolling body, wherein the copper retaineris of an integrated structure and consists of an inner side edge, an outer side edge and a plurality of pocket cross beams; the inner side edge and the outer side edge are connected through the pocketcross beams; and the part between the two sides of each pocket cross beam is a pocket wall. The cylindrical roller bearing has the characteristics of high strength, high rotating speed, long servicelife, capability of meeting outer ring guide or inner ring guide, low vibration, low noise, good lubrication and uniform heat dissipation, and is mainly suitable for precise equipment.

Description

technical field [0001] The invention belongs to the technical field of cylindrical roller bearings. It specifically relates to a cylindrical roller bearing with an integral solid copper cage, which is mainly suitable for precision equipment. Background technique [0002] Cylindrical roller bearings include inner ring, outer ring, cage and rolling elements. The cage evenly distributes the rollers on the circumference of the raceway to prevent the rollers from colliding and rubbing against each other during operation, and guides and drives the rollers in the correct rolling position. Roll on the road. At present, the cylindrical roller bearing with copper cage is used, and the cage is two-piece, that is, the ring frame body of the cover and the seat is butted together and riveted together by high-frequency heating. The disadvantages of this structure cage are: the design structure is not reasonable enough, the cover and the seat are riveted by high-frequency heating, due to ...
