Abstract

The utility model relates to a ball bearing, and in particular relates to a disassembling/assembling-type ball bearing. The ball bearing comprises an outer ring, an inner ring and balls, wherein the balls are positioned between the inner ring and the outer ring; the inner ring is movably connected with a retainer ring; a rotating groove is formed in the inner ring; the retainer ring is embedded into the rotating groove through a convex ring on the reverse surface of the retainer ring so as to be movably connected with the inner ring; a concave discharging opening is formed in the retainer ring; the size of the concave discharging opening is greater than that of each ball. According to the ball bearing, the damaged and rusted balls can be simply and conveniently replaced, namely, the replacement of the whole bearing is not required. Thus, the cost is saved and the efficacy is improved.

Description

The type of removing stage makeup and costume ball bearing

Technical field

The utility model relates to a kind of ball bearing, the type of especially removing stage makeup and costume ball bearing.

Background technique

Existing ball bearing is all to consist of the outer ring of bearing, inner ring and ball, reduce the frictional force in power transmission process and improve the mechanokinetic transmission efficiency with means of rolling, but existing ball can't take out, when ball corrosion or damage, can only change whole bearing, be unfavorable for saving cost.

The model utility content

Can't change the deficiency of ball in order to overcome existing ball bearing, the utility model provides the type ball bearing of removing stage makeup and costume.

The technological scheme that its technical problem that solves the utility model adopts is: the type of removing stage makeup and costume ball bearing, comprise outer ring, inner ring and ball, and ball is placed between inner ring and outer ring, and inner ring and back-up ring are flexibly connected.

According to another embodiment of the present utility model, comprise that further inner ring is provided with rotation slot, back-up ring is embedded in rotation slot by the bulge loop of its reverse side, realizes the flexible connection with inner ring.

According to another embodiment of the present utility model, comprise that further back-up ring is provided with the recessed mouth that unloads, the recessed size of mouth of unloading is greater than the ball size.

The beneficial effects of the utility model are, the replacing damage that this ball bearing can be easy or the ball of corrosion, and need not change whole bearing, and saved cost, improved effect.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model;

1. outer rings in figure, 2. inner ring, 3. ball, 4. back-up ring, 5. rotation slot, 6. bulge loop, the 7. recessed mouth that unloads.

Embodiment

Structural representation of the present utility model as Fig. 1, the type of removing stage makeup and costume ball bearing, comprise outer ring 1, inner ring 2 and ball 3, ball 3 is placed between inner ring 2 and outer ring 1, and inner ring 2 is flexibly connected with back-up ring 4, and inner ring 2 is provided with rotation slot 5, back-up ring 4 is embedded in rotation slot 5 by the bulge loop 6 of its reverse side, realize and the flexible connection of inner ring 2, back-up ring 4 is provided with the recessed mouth 7 that unloads, and the recessed size of mouth 7 of unloading is greater than ball 3 sizes.

When needs are changed the ball 3 that damages, only need to rotate back-up ring 4, make the recessed mouthful ball 3 that 7 alignings damage that unloads on back-up ring 4, then ball 3 is shifted out outside bearing by the recessed mouth 7 that unloads, finally new ball 3 is installed into bearing by the recessed mouth 7 that unloads, rotate again back-up ring 4, make recessed mouthful 7 spaces of aiming between ball 3 that unload get final product, the replacing damage that this ball bearing can be easy or the ball of corrosion, and need not change whole bearing, save cost, improved effect.
