Description
Technical field
The utility model is related to component of machine technical field, specially a kind of wear-resisting expansion set.
Background technology
Expansion set belongs to mechanical spare part in common use category, for coupling two axles (driving shaft and driven shaft) in different institutions
It is allowed to rotate with the machine components of transmitting torque jointly, traditional expansion set will prevent the inclination of conjunction, otherwise work when mounted
Abrasion can be produced in work, affected by working condition, the problems such as wearing and tearing often occurs in expansion set component, and such as sintering machine spindle drive is swollen
With the face of the expansion set matching part diameter of axle about 50%, set etc., occurs that abrasion, traditional restorative procedure are difficult to repair such failure, mesh
Field repair is carried out using polymer composite for expansion set abrading section more than front.
Utility model content
The purpose of this utility model is to provide a kind of wear-resisting expansion set, possesses the advantage of good wearability, solves swollen
After set abrasion, overall repairing efficiency spends time longer problem.
For achieving the above object, the utility model provides following technical scheme：A kind of wear-resisting expansion set, including expansion set body,
Inner sleeve and wearing layer, the expansion set body are in cylinder, and inner hollow is provided with inner sleeve, and the inner sleeve superficial layer is provided with resistance to
Mill layer, the expansion set body are provided with some equally distributed swollen grooves, and the swollen groove end is provided with swollen hole, equidistant in the inner sleeve
From multiple bolts are distributed, the bolt is threadedly coupled with inner sleeve.
Preferably, adjacent swollen groove on the expansion set body is towards on the contrary.
Preferably, the inner sleeve is cone-shaped, and taper is between 3 ° to 5 °.
Preferably, the wearing layer is made up of titanium matter.
Preferably, the expansion set body end face is provided with cover plate.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, after the utility model inner surface sets up wearing layer, after expansion set is contacted with axle binding site sizing die for a long time, can
Effectively to prevent the inner surface of expansion set from wearing and tearing, so as to extend the service life of expansion set.
2nd, by being provided with some equally distributed swollen grooves in expansion set surface body, swollen groove end is provided with swollen the utility model
Hole so that expansion set can swollen get Geng Kai, while the gap in expansion set matching part diameter of axle face can be eliminated, make stress more balanced, subtract
The problem that expansion set matching part diameter of axle face occurs abrasion is lacked.
3rd, the utility model expansion set end face is provided with cover plate, it is therefore prevented that expansion set to work long hours and cause conjunction because of external environment
The wear problem of contact site, increases the service life.
Description of the drawings
Fig. 1 is a kind of wear-resisting expansion set cross-sectional view of the utility model；
Fig. 2 is a kind of wear-resisting expansion set top view of the utility model.
In figure：1- expansion set bodies, 2- inner sleeves, 3- wearing layers, 4- is swollen groove, 5- is swollen hole, 6- bolts.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Embodiment in based on the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of wear-resisting expansion set, including expansion set body 1, interior
Set 2 and wearing layer 3,1 body of expansion set sheet are in cylinder, and inner hollow is provided with inner sleeve 2, and 2 superficial layer of the inner sleeve is arranged
There are wearing layer 3, the expansion set body 1 to be provided with some equally distributed swollen grooves 4,4 end of swollen groove is provided with swollen hole 5, described
Multiple bolts 6 are equidistantly distributed in inner sleeve 2, and the bolt 6 is threadedly coupled with inner sleeve 2.
Operation principle：Expansion set is coupled with driving shaft and driven shaft respectively, is allowed to rotate with transmitting torque jointly, and expansion set makes
With during, inner sleeve can be contacted with matching part diameter of axle face, under long-term extruding, 2 surface of inner sleeve be susceptible to abrasion or
Burr is produced, so as to damage matching part diameter of axle face, after 2 surface of inner sleeve increases wearing layer 3, can effectively prevent expansion set from grinding
Damage, so as to extend the service life of expansion set, expansion set will prevent the inclination of conjunction when mounted, can produce mill in otherwise working
Damage, by being provided with some equally distributed swollen grooves 4 in expansion set surface body, 4 end of swollen groove is provided with swollen hole 5 so that expansion set energy
Enough swollen get Geng Kai, while the gap in expansion set matching part diameter of axle face can be eliminated, make stress more balanced, reduce expansion set auxiliary section
Position diameter of axle face occurs the problem of abrasion, makes expansion set produce normal pressure with diameter of axle face by tightening high-strength bolt 6, produces together
Frictional force, is tightened with 1/3MA values after gap is eliminated, is tightened with 1/2MA values, tightened with MA values, checks whole bolts with MA values,
Whole bolts 6 are first unclamped during dismounting, but bolt 6 should not all be back-outed, remove the galvanized bolt 6 of ejection, liftout bolt 6 is revolved
Enter in the auxiliary screw of front pressure ring, gently tap by the driving member of swelling so as to which tensioner ring loosens, and then gently taps by swelling
Driving member so as to tensioner ring loosen, you can dismounting.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
Be appreciated that these embodiments can be carried out multiple changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
