Abstract

The utility model relates to a kind of biserial, two half inner ring pressing cage closing-in mould, comprises patrix, bearing inner race, steel ball, pressing cage and closing-in mould; Patrix is T-shaped, and outside it, the end face of cylindrical contacts with pressing cage upper-end surface, and the bottom of patrix is placed in the hole of bearing inner race, plays correct location and the effect of leading; Pressing cage is hollow circular ring shape shape, and its sidewall evenly has pocket hole, and pressing cage is positioned over the outside of bearing inner race, and steel ball is placed in the pocket hole of pressing cage, for convenience of the assembling of bearing, inside steel ball and between bearing inner race rib, leaves gap; The working surface of closing-in mould is inclined-plane shape, and the decile spacing by steel ball on Closing in die also has vertical hole, mainly in order to avoid the situation of steel ball damage occurs pressing cage in closing in process; The inclined-plane of closing-in mould and the contact outside of retainer, closing-in mould is sheathed on the bottom of bearing inner race.The utility model thoroughly stops the sequence of sanqu songs within a particular musical mode problem of bearing inner race, retainer and firm ball.

Description

Biserial, two half inner ring pressing cage closing-in mould

Technical field

The utility model relates to a kind of pressing cage closing-in mould, the closing-in mould that biserial, two half inner ring pressing cage are special specifically.

Background technique

Due to the plagiodont gear that automobile gearbox gear generally all adopts, the bearing on its gear shaft bears the axial force of radial force and alternation simultaneously.In view of this situation, at present, general employing fills tapered roller bearing at the two ends of gear shaft, and tapered roller bearing exists, and structure is relatively large, limit speed is relatively low and the necessary problem used in pairs.And adopt biserial, two half inner ring angular contact ball bearing, not only compact structure, and do not need to use the axial force just can bearing alternation in pairs.

How to solve biserial, the scuffing of two half inner ring angular contact ball bearings steel ball surface in assembly process and problem, the accumulating of bearing can be facilitated again simultaneously, be current biserial, two half inner ring angular contact ball bearing assembles the difficult problem run into.

Summary of the invention

The utility model is intended to the defect overcoming prior art, provides a kind of biserial, two half inner ring angular contact ball bearing pressing cage closing-in mould, thoroughly stops the sequence of sanqu songs within a particular musical mode problem of bearing inner race, retainer and steel ball.

In order to solve the problems of the technologies described above, the utility model is achieved in that

A kind of biserial, two half inner ring angular contact ball bearing pressing cage closing-in mould, is characterized in that: comprise patrix, bearing inner race, steel ball, pressing cage and closing-in mould;

Patrix is T-shaped, and outside it, circle end face contacts with pressing cage upper-end surface, and the bottom of patrix is located in the hole of bearing inner race, plays correct location and the effect of leading.

Pressing cage is hollow circular ring shape shape, and its sidewall evenly has pocket hole, and pressing cage is positioned over the outside of bearing inner race, and steel ball is placed in the pocket hole of pressing cage, for convenience of the assembling of bearing, inside steel ball and between bearing inner race rib, leaves gap.

The working surface of closing-in mould is inclined-plane shape, and the decile spacing by steel ball on Closing in die also has vertical hole, mainly in order to avoid the situation of steel ball damage occurs pressing cage in closing in process; The inclined-plane of closing-in mould and the contact outside of retainer, closing-in mould is sheathed on the bottom of bearing inner race.

The beneficial effects of the utility model are: by applying certain external force on pressing cage patrix, pressing cage is made to produce length travel, pressing cage is in length travel process, with the contact of incline plane of closing-in mould, along with the increase of the length travel amount of pressing cage, pressing cage radial direction produces shrinks, the radial displacement of steel ball in pressing cage pocket hole is progressively reduced, achieving steel ball can flexible rotating in pressing cage, simultaneously, also ensure that bearing inner race, it is one that pressing cage and steel ball become all the time, solve the problem not occurring the sequence of sanqu songs within a particular musical mode in accumulating and installation process.

Accompanying drawing explanation

Below in conjunction with drawings and embodiments, the utility model is described in further detail:

Fig. 1 be bearing inner race and steel ball assembling time structural representation.

Fig. 2 is structural representation of the present utility model.

Fig. 3 is the structural representation of pressing cage.

Embodiment

As shown in Figure 1, 2, 3: a kind of biserial, two half inner ring pressing cage closing-in mould, comprise patrix 1, bearing inner race 2, steel ball 3, pressing cage 4 and closing-in mould 5;

Pressing cage is hollow circular ring shape shape, and its sidewall evenly has pocket hole, and pressing cage is positioned over the outside of bearing inner race, and steel ball is placed in the pocket hole of pressing cage, for convenience of the assembling of bearing, and, inside steel ball and between bearing inner race rib 9, leave gap;

As shown in Figure 1: have certain gap when bearing assemble between steel ball and bearing inner race rib 9, this is to ensure that situation about scratching does not occur steel ball in assembly process, otherwise can have influence on the working life of bearing.

As shown in Figure 2: in order to prevent steel ball from dropping out, by pressing cage Closing in die, the radial diameter at retainer pocket hole place being zoomed in, thus limits the radial displacement of steel ball, guarantee that bearing inner race, retainer and steel ball shape are integral.

By applying certain external force on patrix, as shown in the direction of arrow in figure, make the curb girder radial contraction of retainer with the inclined-plane of closing-in mould after, steel ball motion locking in certain scope, thus reach steel ball can be made at retainer flexible rotating, meanwhile, steel ball can not be scattered again, makes bearing inner race, retainer and firm spherical integral.

Claims
