Abstract

The utility model relates to a bearing axle for a bicycle, which is formed by that the front and the back axle leather of the existing bicycles in various types, a miniature bearing, an axle rod, etc. are assembled, wherein, the inner sides of both ends of the axle body are embedded into the miniature bearing; the axle rod whose both sides are provided with two symmetric lug bosses (or stopping nails) is strung into core holes at the inner sides of both ends of the axle body embedded into the miniature bearing. A cushion ring and a stop nut are arranged near to the outer sides of both ends strung into the miniature bearing on the axle rod. The utility model has the advantages of convenient maintenance, easy use, lightness and labor saving, increasing maintenance kilometers and running kilometers, and the utility model can be used for the bicycles in various types.

Description

The bicycle bearings axle

The utility model belongs to a kind of accessory of the vehicle, particularly one group of bicycle bearings axle.Sell and use the various trade mark bicycles of various models in the market, employed front and back axletree is made up of axle skin, axle bowl, steel ball, axle rod, axle shelves, cover of dust and nut etc.Main tumbler of bicycle such as front axle rear axle etc. are located, in daily use, answer running check and levelling, make its gap minimum, rotating could be flexibly, also should change every year such as butter of filling, lubricated front axle rear axle etc. and locate rotatable parts, reduce heel and toe wear, these work bring a lot of troubles for routine and life.Front axle rear axle steel ball is loosening can to cause axle shelves and axle bowl steady acceleration wearing and tearing again with tension, in time changes again after the wearing and tearing, and this has brought inconvenience for again routine and life.

The purpose of this utility model is to overcome the prior art weak point, provides one group of easy to use, maintenance make things convenient for, to save labor, can to prolong maintenance kilometer, the bicycle bearings axle of raising running kilometre.

The utility model is achieved in that

The utility model adopts existing various model bicycle antero posterior axis skins, removes axle bowl, steel ball, the cover of dust at antero posterior axis intracutaneous two ends.Embed a miniature bearing at its front axle intracutaneous one end, an end also embeds and is different from the another one miniature bearing that the front axle intracutaneous embeds the miniature bearing model in the backshaft skin.Remove two side shaft shelves on the antero posterior axis rod, each punching press on its antero posterior axis rod (or boring edge non-magnetic shim) and antero posterior axis skin both sides embed the inboard stop of two symmetrical boss (or non-magnetic shim) that the inner distance of bowl equates as miniature bearing.The front axle rod is sealed in front axle intracutaneous with embedding one end miniature bearing, embed the miniature bearing of an equal model at its other end again.The rear axle rod is sealed in the backshaft skin with embedding one end miniature bearing, embed the miniature bearing of an equal model at its other end again.Respectively load onto packing ring and stop nut at the antero posterior axis skin with the good miniature bearing of embedding and the outside that seals in a rod.

Advantage of the present utility model is:

1, do not use axle bowl, steel ball, axle shelves, cover of dust in the axis body, when needs overhaul, only need to change the miniature bearing that axis body is embedded in, reduce trouble, not cumbersome, service work is saved labor, bring convenience to service work.

2, do not use axle bowl, steel ball, axle shelves, minimizing heel and toe wear in the axis body, prolong the maintenance kilometer.

3, do not need the gap of running check and levelling axle bowl, steel ball, axle shelves in the axis body, save time, easy to use.

4, use is brisk, saves labor, and improves running kilometre.

5, can be used on the various trade mark bicycles of various models.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:
