Two-piece bearing outer ring crossed rolling bearing

Abstract

The invention discloses a two-piece bearing outer ring crossed rolling bearing. The two-piece bearing outer ring crossed rolling bearing comprises upper and lower outer rings, a bearing inner ring, aroller, a rivet hole, a ball slide way, a reserved gap, upper and lower groove surfaces, and an inner ring groove; the inner ring groove is arranged on the outer peripheral surface of the bearing inner ring; the upper ring groove surface is arranged on the inner side of the upper outer ring; the lower ring groove surface is arranged on the inner side of the lower outer ring; the upper and lower ring groove surfaces and the inner ring groove form the ball slide way; crossed rollers are fully distributed in the ball slide way; and the reserved gap is formed between butt joint surfaces of the upper and lower outer rings, enables the upper and lower outer rings to separate from each other, and keeps non-contact configuration of the upper and lower outer rings. A bearing outer ring adopts a two-piece non-contact separation structure, and is fixed by adopting glue and rivets during grinding without generating the phenomenon of nonuniform groove wall thickness; and the reserved gap is formedbetween two halves of the outer ring, so that the outer ring can be recycled after being worn through repair.

Description

technical field [0001] The invention relates to the field of technical equipment of crossed roller bearings, in particular to a crossed roller bearing with two half bearing outer rings. Background technique [0002] Crossed roller bearings are widely used in all walks of life. The bearings have the characteristics of high rigidity, high precision, can carry a certain load, and can still ensure accuracy at high speeds. However, due to the structural characteristics of cross roller bearings, the assembly process is more complicated, and the grinding process is more cumbersome; currently, the cross roller bearings appearing on the market are more complicated to assemble and are not easy to assemble. [0003] In the prior art, the crossed roller bearings are fixed by screws during grinding, and its disadvantages are: 1. Its disadvantage is that it is difficult to fix for small bearings. The upper and lower halves of the processed cross roller bearing are tightly crimped and fix...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides a two-half type bearing outer ring cross roller bearing, aiming at the deficiencies in the prior art, adopts a two-half bearing outer ring, separated from each other and non-contact structure, and the inner ring adopts One-piece structure configuration; when assembling, fix the upper half of the outer ring and the inner ring on the assembly table, and manually cover the rollers evenly in the ball slideway, and then fasten the lower half of the outer ring to the upper half of the outer ring At the same time, put the bearing into the transfer fixture for transportation and assembly; the two-half outer ring does not need to be fixed by four screws when grinding, and is fixed by special glue and rivets, so that the groove wall will not appear thin and thick during grinding Inhomogeneity, there is a gap between the two halves of the outer ring, and it can be used again after repairing after wear
