Abstract

The invention discloses a processing method for a bearing. The processing method comprises the following steps: 1, processing and forming an inner bearing ring and an outer bearing ring; 2, axially forming a through hole in the outer bearing ring in a penetrating manner; 3, cutting a clamping block from the outer bearing ring by virtue of linear cutting, wherein the through hole is divided into a first through hole and second through holes in two sides of an incision of the outer bearing ring by the cut clamping block; 4, embedding balls between the outer bearing ring and the inner bearing ring; and 5, putting the clamping block into the incision, inserting an insertion pin into the first through hole and the second through holes in a penetrating manner to form interference fit. The requirement on the bearing processing precision is high, so that after the outer bearing ring is processed, the clamping block is cut from the outer bearing ring by linear cutting; in order to guarantee the matching precision of the first through hole and the second through holes, the hole is firstly formed, and then the clamping block is cut off. The bearing processed by the method disclosed by the invention is high in bearing capacity; furthermore, compared with an existing crowded ball bearing, the bearing has the advantages that the service life is greatly prolonged, and the safety is relatively high.

Description

A kind of bearing processing method

Technical field

The invention belongs to technical field of bearings, specifically a kind of processing method of bearing.

Background technique

Existing bearing generally comprises bearing inner race, bearing outer ring, ball and retainer, existing by the tangent setting of bearing inner race and outer ring when bearing machining, then between bearing inner race and bearing outer ring, ball is put into, again the center of bearing inner race is moved to the center superposition with bearing outer ring, this process simultaneously ball is encased between bearing inner race and bearing outer ring, because such processing mode makes ball cannot be full of space between whole bearing outer ring and bearing inner race, if ball is simultaneously to bearing inner race and bearing outer ring may be caused during a lateral movement to depart from and cause danger, therefore the dispersed state of ball will be kept after ball scattering device by retainer.Only adopt the bearing processed in this way and have following shortcoming: 1, underfill ball between bearing inner race and bearing outer ring, therefore the bearing capacity of bearing is less; 2, owing to being that face contacts between ball with retainer, the rubbing surface therefore between retainer and ball is comparatively large, the serious wear between ball and retainer, thus makes the bearing integral life-span short.

In order to improve the bearing capacity of bearing and reduce ball wearing and tearing and extend bearing working life, design full ball bearing, existing full ball bearing comprises bearing inner race, bearing outer ring, and the ball between bearing inner race and bearing outer ring, described bearing outer ring side is provided with the first breach, described bearing inner race is provided with the second breach, after two notch alignment, ball is loaded between bearing outer ring and bearing inner race, adopt this mounting type all can be full of between bearing inner race and bearing outer ring, thus increase the bearing capacity of bearing, simultaneously owing to being filled with ball between bearing inner race and bearing outer ring, also need not worry that ball is all rolled into the side of bearing and bearing inner race and bearing outer ring are departed from.But because after the first breach and the second notch alignment, ball can pass, when therefore receiving lateral stress in use, there is certain risk, in order to prevent running out of of ball, the ball both sides of this kind of full ball bearing still need to arrange retainer, bring so again the drawback of retainer, namely the serious wear between ball and retainer, thus make the bearing integral life-span short.

Summary of the invention

The present invention is directed to prior art deficiency, a kind of processing method of bearing is provided, adopt the bearing of the method processing to have high-bearing capacity, and relatively existing full ball bearing increases working life greatly, and Security is higher.

In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of processing method of bearing, comprises the following steps: 1, by bearing inner race and bearing outer ring machine shaping; 2, at the axial reach through hole of bearing outer ring; 3, bearing outer ring adopts Linear cut to cut out clamping block, and through hole is divided at the first through hole and the second through hole in bearing outer ring fracture both sides by the clamping block cut out; 4, between bearing outer ring and bearing inner race, ball is loaded; 5, clamping block is loaded in fracture and latch is penetrated interference fit in the first through hole and the second through hole, because the requirement on machining accuracy of bearing is high, therefore first from bearing outer ring, clamping block is cut out with Linear cut again by after bearing outer ring machine shaping, in order to ensure the quality of fit of the first through hole and the second through hole, therefore first carry out punching cutting out clamping block again, adopt the bearing of the method processing to have high-bearing capacity, and relatively existing full ball bearing increases working life greatly, and Security is higher.

The present invention compared with prior art, has following beneficial effect: adopt the bearing of the method processing to have high-bearing capacity, and relatively existing full ball bearing increases working life greatly, and Security is higher.

Embodiment

Be described in further detail the present invention below in conjunction with accompanying drawing and embodiment: see Fig. 1 to Fig. 2, a kind of processing method of bearing, comprises the following steps: 1, by bearing inner race 2 and bearing outer ring 1 machine shaping; 2, at the axial reach through hole of bearing outer ring 1; 3, bearing outer ring 1 adopts Linear cut to cut out clamping block 12, and through hole is divided at the first through hole 121 and the second through hole 111 in bearing outer ring fracture 11 both sides by the clamping block 12 cut out; 4, between bearing outer ring 1 and bearing inner race 2, ball 3 is loaded; 5, clamping block 12 is loaded in fracture 11 and latch 4 is penetrated interference fit in the first through hole 121 and the second through hole 111, because the requirement on machining accuracy of bearing is high, therefore first from bearing outer ring 1, clamping block 12 is cut out with Linear cut again by after bearing outer ring 1 machine shaping, in order to ensure the quality of fit of the first through hole 121 and the second through hole 111, therefore first carry out punching cutting out clamping block 12 again.

Adopt the bearing that the method processes, comprise bearing outer ring 1 and bearing inner race 2, ball 3 is provided with between described bearing outer ring 1 and described bearing inner race 2, described bearing outer ring 1 is provided with fracture 11, described fracture 11 is provided with clamping block 12, described ball 3 can pass described fracture 11, described clamping block 12 is provided with at least two the first through holes 121, described fracture 11 both sides are provided with at least two the second through holes 111, first through hole 121 described in when described clamping block 12 loads in described fracture 11 is coaxial with described second through hole 111, latch 4 is provided with in described first through hole 121 and described second through hole 111.This bearing 4 makes the space between bearing inner race 2 and bearing outer ring 1 can be filled by ball 3 by loading ball 3 at fracture 11 when mounted, and then clamping block 12 loaded in fracture 11 adopt latch 4 to fix, adopt this structure that the bearing capacity of bearing can not only be made to increase, do not need that retainer is installed to run out of to prevent ball 3 simultaneously, ball 3 would not be made to contact with face between retainer, thus reduce the wearing and tearing of ball, thus increase working life.
