Abstract
The utility model relates to a bicycle part improvement, in particular to a bicycle shaft ball cage, which comprises a ball cage and rolling balls. Pluralities of arc hooked external claws are evenly arranged on the inner ring of the ball cage to clamp the rolling balls. The utility model is characterized in that internal claws are arranged on the ball cage in the position that corresponds to the external claws. After connected, the external claws and the internal claws form clamping rings. A single rolling ball can be clamped between two clamping rings. The utility model has the good effect that the rolling ball clamped between two clamping rings will not come off easily when a bicycle is being assembled. Waste is reduced and the of cost of bicycle assembling is also reduced. Besides, assembling efficiency is improved.
Description
Technical field
The utility model belongs to the improvement of attachments of a bicycle, relates in particular to a kind of axle for bicycle ball-collecting rack that does not fall ball.
Background technique
Each rotating shaft part of bicycle all adopts ball-collecting rack as rolling bearing.The tradition ball-collecting rack is made up of pearl frame and ball, and ring is gone up the outer pawl of circular arc crotch of several clamping balls that evenly distribute in the pearl frame, evenly distribute its apart between the ball use time can on the pearl frame, freely rotate.Yet when bicycle trade used this kind pearl frame hand assembled bicycle, the operator one exerted oneself slightly, ball easily influences the use effect from deviating between outer pawl, meets all class situations and only can more renew the pearl frame and ressemble, therefore, both influence efficiency of assembling, caused waste again.
The model utility content
The purpose of this utility model is intended to overcome above-mentioned defective, and a kind of axle for bicycle ball-collecting rack that does not fall pearl is provided.
For realizing the purpose of this utility model, the technological scheme that adopts is, a kind of axle for bicycle ball-collecting rack, mainly containing pearl frame and ball forms, ring upward evenly distributes in the pearl frame, and several clamp the outer pawl of circular arc crotch of ball, it is characterized in that corresponding outer claw position is provided with interior pawl on the described pearl frame, interior pawl docks the back and forms snap ring, clamping simple grain ball between its snap ring and the snap ring with outer pawl.
The beneficial effects of the utility model are to adopt the structure of the snap ring clamping ball that the upward inside and outside claw type of ring becomes in the pearl frame that the ball on the pearl frame is no longer come off in assembling bicycle process, promptly can cut the waste, reduce the car load installation cost, can improve the efficient of assembling car again.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples structure of the present utility model is further described.
With reference to Fig. 1-Fig. 2, a kind of axle for bicycle ball-collecting rack, mainly contain pearl frame 1 and ball 2 compositions, ring upward evenly distributes in the pearl frame, and several clamp the outer pawl 3 of circular arc crotch of ball, it is characterized in that, pawl 4 in corresponding outer claw position is provided with on the described pearl frame, interior pawl docks the back and forms snap ring, clamping simple grain ball between its snap ring and the snap ring with outer pawl.
Working process of the present utility model is: the ball-collecting rack blank of pawl and outer pawl at first punching press has, and interior pawl moulding, the ball of on special-purpose mold, packing into, the outer pawl that bends again makes in ball is clamped between the snap ring distance that interior pawl becomes with outer claw type.The utility model is applied to each shaft drive position on the bicycle.
The above only is preferred embodiment of the present utility model, is not shape of the present utility model, material and structure are done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
