Abstract
The utility model relates to an axle sleeve for mechanical seal, include sectional type axle sleeve, rotating ring, quiet ring, arrange in the outer intermediate flange of sectional type axle sleeve, arrange in bottom flange and top flange, tapered bore bearing, locating piece, lock nut, first locking ring and the second locking ring of intermediate flange both sides, the sectional type axle sleeve includes front shaft sleeve and rear axle housing, be equipped with T type piece on the rear axle housing, it is corresponding the last T type groove that is equipped with of front shaft sleeve, the rear axle housing surface is equipped with the taper surface, be taper fit between tapered bore bearing and the rear axle housing. The adoption divide into two sections with the mechanical seal axle sleeve between, with the hookup of T type piece, and the bearing adopts the tapered bore bearing, and bearing section axle sleeve be the opening axle sleeve, during the installation and tight rear bearing and axle sleeve within a definite time, axle sleeve and the betweencenters zero clearance that closely cooperates. T type piece guarantees that front shaft sleeve's axial position is certain, plays rotatory gearing simultaneously. Front shaft sleeve can not receive the radial force like this, moves along with the axle at the operation in -process, and is reliable and stable.
Description
Technical field
The utility model is related to a kind of mechanical seal, more particularly to a kind of mechanical seal axle sleeve.
Background technology
Majority is the structure with bearing in agitator mechanical seal, due to the presence (rubber of mechanical seal auxiliary member
Part), it is not allow heating in installation process, cause the cooperation between mechanical seal sleeve and agitator axle to be gap
Coordinate.The bounce of agitator axle can cause repeated stock to wear and tear in axle sleeve, this abrasion be not on new stirrer it is obvious that
But abrasion can be clearly caused between when in use on longer equipment.
Utility model content
In view of the above-mentioned state of the art, technical problem to be solved in the utility model is to provide a kind of reduction axle
Set abrasion, improves the mechanical seal axle sleeve of service life.
The utility model solve the technical scheme that adopted of above-mentioned technical problem for：A kind of mechanical seal axle sleeve, including
Segmented axle sleeve, rotating ring, stationary ring, the spacer flanger being placed in outside the segmented axle sleeve, the bottom that is placed in the spacer flanger both sides
Portion's flange and top flange, tapered bore bearing, locating piece, locking nut, the first retaining ring and the second retaining ring；The segmented axle
Set includes front shaft sleeve and rear axle housing, and the rear axle housing is provided with T-shaped piece, accordingly, T-slot, institute is provided with the front shaft sleeve
State rear axle housing surface and be provided with taper surface, be taper fit between the tapered bore bearing and rear axle housing, the top flange will be described
Tapered bore bearing is compressed.
Further, the rotating ring is connected to front shaft sleeve by stop pin, and the throw-out collar of the stationary ring is placed in spacer flanger,
Support ring is provided with outside the throw-out collar, in the throw-out collar and supports ring surface to be cased with bellows, the flange in the bottom is by bellows pressure
Tightly, the bellows leading portion is provided with stationary ring retaining ring.
Compared with prior art, the beneficial effects of the utility model are：It is divided into two sections using by mechanical seal sleeve, between
With T-shaped piece of connection, bearing adopts tapered bore bearing, and bearing section axle sleeve is split bush, during installation and it is tight after bearing and shaft room, axle
Set is fitted close gapless between centers.The axial location of T-shaped piece of guarantee front shaft sleeve is certain, while playing rotary drive effect.So
Front shaft sleeve will not receive radial load, move with axle in running, reliable and stable；In addition, using arranging bellows outside stationary ring,
Improve the floatability of stationary ring, it is ensured that efficient, the lasting operation of mechanical seal.The utility model is reasonable in design, is adapted to push away on a large scale
Extensively.
Description of the drawings
Fig. 1 is overall structure sectional view of the present utility model；
Fig. 2 is front shaft sleeve structure sectional view of the present utility model；
Fig. 3 is rear axle housing structure sectional view of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, to the skill embodiment in the utility model embodiment, and
It is not all, of embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creativeness
The every other embodiment obtained under the premise of work, belongs to the scope of the utility model protection.
As Figure 1-3, it is a kind of mechanical seal axle sleeve described in the utility model, including segmented axle sleeve, rotating ring 2, quiet
Ring 3, the spacer flanger 7 being placed in outside the segmented axle sleeve, the flange in the bottom 6 and top method that are placed in the both sides of the spacer flanger 7
Blue 8, tapered bore bearing 14, locating piece 9, locking nut 10, the first retaining ring 11 and the second retaining ring 12；The segmented axle sleeve bag
Front shaft sleeve 1 and rear axle housing 13 are included, the rear axle housing 13 is provided with T-shaped piece 15, accordingly, on the front shaft sleeve 1 T-slot is provided with
19, the surface of the rear axle housing 13 is provided with taper surface 18, is taper fit between the tapered bore bearing 14 and rear axle housing 13, the top
Portion's flange 8 compresses the tapered bore bearing 14.The rotating ring 2 is connected to front shaft sleeve 1, the throw-out collar of the stationary ring 3 by stop pin
16 are placed in spacer flanger 7, and outside the throw-out collar 16 support ring 17 is provided with, and in the throw-out collar 16 and the surface of support ring 17 ripple is cased with
Pipe 5, the flange in the bottom 6 compresses bellows 5, and the leading portion of the bellows 5 is provided with stationary ring retaining ring 4.The locking nut 10,
First retaining ring 11 and the second 12 rings of locking are threadedly connected to successively the end of rear axle housing 13, are provided with outside the locking nut 10
Locating piece 9, the locating piece 9 is fixed with top flange 8 by screw.
Compared with prior art, the beneficial effects of the utility model are：It is divided into two sections using by mechanical seal sleeve, between
