Abstract

It the utility model is related to a kind of semiaxis bearing anti-loose structure, including combining pintle hook lock, described combination pintle hook lock is made up of two pieces of fixture blocks and two pieces of fixtures, described fixture block is semi-circular structure, it is step structure at its radial direction, two pieces of fixture blocks are symmetric and are clamped on axle, and the seam crossing between fixture block tears side radially parcel fixture block open by fixture；The internal diameter of described fixture block is equal with the axle ditch footpath of axle where fixture block；It is micro- interference fit between the axial location and bearing, compact heap of described fixture block；The beneficial effects of the utility model are：By using assembling lock card structure, axially position is micro- interference fit, and the bearing on semiaxis, compact heap is effectively whole as one, improves security and improves anti-loose ability simultaneously, lifts the performance of semiaxis；It can in addition contain reduce compact heap part, cost is reduced.

Description

A kind of semiaxis bearing anti-loose structure

Technical field

The utility model belongs to anti-loose structure technical field, more particularly to a kind of semiaxis bearing anti-loose structure.

Background technology

At present, applied to pick up, SUV, light-duty commercial vehicle, when using semi-axis structure, the locking to bearing, such as accompanying drawing Shown in 1, it is made up of axle 1, shell 2, bearing 3, circlip for shaft 4 and compact heap 5, is interference fitted and compresses by the internal diameter of bearing 3 The internal diameter of block 5 is interference fitted, and with the axially position of circlip for shaft 4, locking, but assembled using circlip for shaft 4 will necessarily In the presence of 0.1~0.3mm axial gap, when turn inside diameter acceleration is larger or there is amount of deflection fluctuation and engender in long-term use Axially position fails, and causes bearing looseness problem occur.

The content of the invention

The purpose of this utility model is to overcome the shortcomings of the prior art, and provides a kind of anti-untwisting of semiaxis bearing Structure, when amount of deflection fluctuates when turn inside diameter acceleration is larger or present in long-term use, it can effectively prevent bearing positioning from occurring Gap and bearing looseness, it is ensured that the pretension of bearing, really realize non-maintaining.

The purpose of this utility model is completed by following technical solution, including combination pintle hook lock, described combination lock Card is made up of two pieces of fixture blocks and two pieces of fixtures, and described fixture block is semi-circular structure, is step structure at its radial direction, this two Block fixture block is symmetric and is clamped on axle, and the seam crossing between fixture block tears side radially parcel fixture block open by fixture.

Preferably, the internal diameter of described fixture block is equal with the axle ditch footpath of axle where fixture block.

Preferably, it is micro- interference fit between the axial location and bearing, compact heap of described fixture block.

The beneficial effects of the utility model are：By using assembling lock card structure, axially position is micro- interference fit, will Bearing, compact heap on semiaxis is effectively whole as one, improves security and improves anti-loose ability simultaneously, lifts the use of semiaxis Performance；It can in addition contain reduce compact heap part, cost is reduced.

Fig. 2 is semiaxis bearing anti-loose structure structural representation of the present utility model.

Label in accompanying drawing is respectively：1st, axle；2nd, shell；3rd, bearing；4th, circlip for shaft；5th, compact heap；6th, combine Pintle hook lock；61st, fixture block；62nd, fixture.

Embodiment

Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in Figure 2, the utility model includes combination Pintle hook lock 6, described combination pintle hook lock 6 are made up of two pieces of fixture blocks 61 and two pieces of fixtures 62, and described fixture block 61 is semi-circular structure, It is step structure at its radial direction, two pieces of fixture blocks 61 are symmetric and are clamped on axle 1, and the seam crossing between fixture block 61 leads to Cross fixture 62 and tear side radially parcel fixture block 61 open, prevent fixture block 61 from coming off.

The internal diameter of described fixture block 61 is equal with the axle ditch footpath of the place axle 1 of fixture block 61.

It is micro- interference fit between the axial location and bearing 3, compact heap 5 of described fixture block 61.

The utility model is not limited to above-mentioned embodiment, makees any change no matter being formed in its shape or material, all It is to use structure design provided by the utility model, is all a kind of deformation of the present utility model, is considered as new in this practicality Within type protection domain.
