Description
Technical field
A kind of heavy-duty car mounting technology is the utility model is related to, more particularly to one kind takes up for heavy-duty car hub spindle
The specific purpose tool matched somebody with somebody.
Background technology
The wheel hub of heavy-duty car is typically connected by axle housing sleeve with vehicle bridge, and the region for setting wheel hub is used on axle housing sleeve
On be provided with small one and large one two taper roll bearings, that small taper roll bearing is located at the outside (special tool of the application
Tool is used to install this small taper roll bearing), that big taper roll bearing is located at inner side, for the ease of describing,
That big taper roll bearing is designated as inner bearing hereinafter, that small taper roll bearing is designated as outer bearing；Based on existing
There is technology to understand that taper roll bearing generally comprises outer ring, inner ring, retainer and multiple rollers, retainer and is arranged on inner ring
On outer peripheral face, multiple rollers are arranged on retainer, and outer ring is socketed in outside retainer；Before assembling, only by inner ring, retainer and rolling
Subgroup installs, and outer ring is unassembled on structure, during assembling, is first installed in place outer ring, is then again socketed in internal structure
In outer ring；Because inner bearing position is inner, after wheel hub is sleeved on axle housing sleeve, it is difficult to installation operation is carried out to inner bearing, because
This, is typically synchronously assembled inner bearing and wheel hub on axle housing sleeve with special press-loading apparatus, then again by wheel hub and axle housing
Sleeve pipe Integral lifting carries out hand assembled by operating personnel to other assembly yard to outer bearing；When installing outer bearing,
It is that outer ring is first installed, then internal structure is installed, Electromagnetic Heating is typically first used because inner ring and axle housing sleeve are tight fit, during assembling
Mode is heated, and after inner ring expanded by heating, its hole size will become big, at this moment multiplies heat and inner ring is enclosed on axle housing sleeve,
So as to realize that outer bearing is installed；The problem of existing be：Electromagnetic Heating needs to use special equipment, cumbersome, and operates
Personnel need carried, assembled when inner ring be in the condition of high temperature etc. to operate, and are easily burned.
Utility model content
The problem of in background technology, the utility model proposes a kind of for the special of heavy-duty car hub bearing assembling
With instrument, the hub bearing is taper roll bearing, and the taper roll bearing includes outer ring, inner ring, retainer and multiple
Roller, the retainer are arranged on the outer peripheral face of inner ring, and multiple rollers are arranged on retainer, and outer ring is socketed in retainer
Outside；The hub bearing is socketed on axle housing sleeve by inner ring, and the heavy-duty car wheel hub is socketed in outside hub bearing, and it changes
Enter to be：The specific purpose tool is made up of body and handle；The body is cylindrical structural body, and the left side of body is flat
Face, circular groove is provided with the right side of body, circular groove is coaxial with body, and the diameter of circular groove is more than the axle housing
The diameter of sleeve pipe, the external diameter of body right side are less than the external diameter of the inner ring；The handle is fixed on the left side of body.
When carrying out assembling work using the utility model, still first the outer ring of outer bearing is assembled in place, then by inner ring
It is socketed on axle housing sleeve, then operator with a portable specific purpose tool and makes the right side of body be against the outer end of inner ring
On face, then hold copper rod with another hand and gently tap the left side of body so that inner ring progressively move inward until
It is installed in place；It is easy to operate without being heated again to inner ring after the utility model, and can avoid scalding, drop
The degree of danger of low operation.
Preferably, it is provided with nylon jacket on the outer surface of the body right-hand member.Nylon jacket can be avoided between metal structure
Directly contact, avoid structure surface tear.
Preferably, the handle is U-shaped structure body, and the opening portion of U-shaped structure body is fixedly connected with the left side of body.
Advantageous effects of the present utility model are：Propose a kind of special tool for the assembling of heavy-duty car hub bearing
Tool, do not have to carry out heating operation again after the specific purpose tool, during assembling, the convenience and security of operation can obtain larger
Improve.
Brief description of the drawings
Fig. 1, structural representation of the present utility model；
Fig. 2, use state diagram of the present utility model；
Title in figure corresponding to each mark is respectively：Body 1, handle 2, nylon jacket 3, inner ring 4, retainer 5, outer ring
6th, axle housing sleeve 7.
Embodiment
A kind of specific purpose tool for the assembling of heavy-duty car hub bearing, the hub bearing is taper roll bearing, institute
Stating taper roll bearing includes outer ring, inner ring, retainer and multiple rollers, and the retainer is arranged on the outer peripheral face of inner ring,
Multiple rollers are arranged on retainer, and outer ring is socketed in outside retainer；The hub bearing is socketed in axle housing sleeve by inner ring
On, the heavy-duty car wheel hub is socketed in outside hub bearing, and its improvement is：The specific purpose tool is by 2 groups of body 1 and handle
Into；The body 1 is cylindrical structural body, and the left side of body 1 is plane, and circular groove is provided with the right side of body 1,
Circular groove and body 1 are coaxial, and the diameter of circular groove is more than the diameter of the axle housing sleeve, and the external diameter of the right side of body 1 is small
In the external diameter of the inner ring；The handle 2 is fixed on the left side of body 1.
Further, it is provided with nylon jacket on the outer surface of the right-hand member of body 1.
Further, the handle 2 is U-shaped structure body, and the opening portion of U-shaped structure body is fixed with the left side of body 1 to be connected
Connect.
