Description
Technical field
The utility model is related to a kind of bearing glands, and in particular to be a kind of bearing gland of screw pump reduction box.
Background technology
The bearing gland of traditional screw pump reduction box（As depicted in figs. 1 and 2）, utilize matching somebody with somebody for outside framework oil seal and pump shaft
It closes, the oil in Gearbox is prevented to be flowed out along bearing, reaches sealing effect；Its centrode is not when being run due to pump shaft
It is constant, but almost elliptical shape, and meeting of the pump shaft during opening, stopping generates large magnitude, makes axis outer circle running orbit
Also it is an elliptical shape；Operationally, since outside framework oil seal does not have positioner, axial float can be generated, easily generates abrasion
Even come off；Outside framework oil seal abrasion can cause the cooling water of feed zone easily to flow into reduction box, threaten the safe operation of unit.
Therefore, the prior art could be improved and improve.
Utility model content
In view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of bearings of screw pump reduction box
Gland, it is intended to solve outside framework oil seal due to no positioner, easily generate axial runout when pump shaft is run, generate abrasion
Problem.
A kind of bearing gland of screw pump reduction box, wherein, including gland body, the first spacing ring, the first outside framework oil seal,
Second outside framework oil seal, the second spacing ring and the first screw；
The gland body offers through hole, and the installation groove of annular, institute are offered on the corresponding madial wall of the through hole
Installation groove is stated along the circumferentially disposed of the through hole, the first spacing ring lateral border is connected in the installation groove, institute
State the second spacing ring to be installed on the outer end face of the gland body, be fixed by the first screw, first outside framework oil seal with
And second outside framework oil seal is overlapped and is connected between first spacing ring and second spacing ring.
The bearing gland of the screw pump reduction box, wherein, the gland body lower surface is equipped with a circle /V annulus.
The bearing gland of the screw pump reduction box, wherein, first outside framework oil seal and the second outside framework oil seal installation side
To opposite.
The bearing gland of the screw pump reduction box, wherein, the quantity of first screw is at least 2.
The beneficial effects of the utility model：The bearing gland of screw pump reduction box provided by the utility model, passes through first
Cooperation between spacing ring, the second spacing ring and the first screw is fixed on first outside framework oil seal and the second outside framework oil seal
Target location, this structure can prevent outside framework oil seal axial float, reduce the abrasion of outside framework oil seal；Two positive and negative installations of setting
The lubricating oil that outside framework oil seal can be better protected from reduction box is leaked out to flow into from outside with the cooling water of feed zone along bearing and subtracted
Fast case improves the security performance of whole unit, extends the service life of whole unit.

Specific embodiment
The utility model provides a kind of bearing gland of screw pump reduction box, to make the purpose of this utility model, technical side
Case and effect are clearer, clear and definite, and the utility model is further described below.It should be appreciated that tool described herein
Body embodiment is only used to explain the utility model, is not used to limit the utility model.
Refering to Fig. 3, the bearing gland of the screw pump reduction box includes gland body 15, the first spacing ring 10, first
Outside framework oil seal 11, the second outside framework oil seal 12, the second spacing ring 13 and the first screw 14；The gland body 15 offers logical
Hole offers the installation groove of annular, circumferential direction of the installation groove along the through hole on the corresponding madial wall of the through hole
It sets, 10 lateral border of the first spacing ring is connected in the installation groove, and second spacing ring 13 is installed on the pressure
It on the outer end face of lid body 15, is fixed by the first screw 14, first outside framework oil seal 11 and second outside framework oil seal
12 overlap and are connected between first spacing ring and second spacing ring.
Specifically, 15 lower surface of gland body is equipped with a circle /V annulus 18.
Specifically, 11 and second outside framework oil seal of the first outside framework oil seal, 12 installation directions are opposite.
Referring again to Fig. 3, the bearing gland of the screw pump reduction box further includes the second screw 16,17 and of the 3rd screw
/V annulus 18, first screw 14 are arranged on the second spacing ring 13 and the surface of 15 intersection of gland body.
Specifically, in order to which gland 13 is made preferably to be fixed in gland body 15, the quantity of first screw is at least 2
It is a.
Referring again to Fig. 3, the gland body 15 is fixed on by the second screw 16, the 3rd screw 17 and /V annulus 18
On screw pump reduction box.
The utility model is improved by pumping speed reduction box shaft pressure cap to classic screw, passes through the first spacing ring 10, the
First skeleton oil 11 and the second outside framework oil seal 12 are limited in target location, this structure energy by two spacing rings 13 and the first screw 14
It prevents outside framework oil seal axial float, reduces the abrasion of outside framework oil seal, set the outside framework oil seal of two positive and negative installations can be preferably
Prevent the lubricating oil of reduction box is leaked out along bearing from flowing into reduction box from outside with the cooling water of feed zone so that whole unit
Security performance higher extends the service life of whole unit.
The utility model is described in detail above, it for those of ordinary skills, can be according to upper
