Abstract
The utility model relates to the technical field of centrifugal pumps, in particular to a bearing mounting and dismounting structure which comprises a pump shaft, a bearing, a bearing body and a bearing press cover. The bearing body and the bearing press cover are arranged on the pump shaft in a sleeved mode, the bearing press cover and the bearing body are fixedly connected, and the bearing is arranged in the bearing body and is fixed on a bearing mounting section of the pump shaft. The bearing mounting and dismounting structure is characterized in that a bearing sleeve nut and a fastening nut are provided, a bearing sleeve nut threaded section is arranged on the front portion of the bearing mounting section of the pump shaft, a fastening nut threaded section is arranged on the rear portion of the bearing mounting section of the pump shaft, the bearing sleeve nut penetrates through the inner wall of an inner hole of the bearing press cover and is then connected with the bearing sleeve nut threaded section of the pump shaft in a threaded mode, the outer wall of the bearing sleeve nut is connected with the bearing press cover in a sealed mode, one end of the bearing sleeve nut abuts against the pump shaft, the other end of the bearing sleeve nut abuts against the inner wall of the bearing, a hooking groove is formed in the side wall of a blocking table at the rear end of the bearing sleeve nut, and the fastening nut is connected with the fastening nut threaded section and then abuts against the other end of the bearing. The bearing mounting and dismounting structure has the advantages that the structure is reasonable, operation is convenient, time and labor are saved, and the bearing is not prone to damage.
Description
Technical field
The utility model relates to centrifugal pump technical field, specifically a kind of bearing dismantling structure.
Background technique
At present, traditional centrifugal pump pump shaft two ends adopt respectively rolling bearing, bearing support to support, and adopt interference fit to be directly loaded on pump shaft, between bearing and pump shaft when changing pump shaft, need first bearing support and bearing removal to be got off, could take out pump shaft, and dismounting bearing, owing to adopting interference fit, need to beat or use professional tool it could be taken out from pump shaft, if so not only waste time and energy, operate badly, just easily damage bearing, cause unnecessary loss.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of bearing dismantling structure rational in infrastructure, easy to operate, time saving and energy saving, not fragile bearing is provided.
The utility model solves the technological scheme that its technical problem adopts:
A kind of bearing dismantling structure, comprise pump shaft, bearing, bearing support and bearing gland, bearing support and bearing gland are enclosed within respectively on pump shaft, bearing gland is fixedly connected with bearing support, in bearing support, be provided with bearing, bearing is fixed on the bearing construction section of pump shaft, it is characterized in that being provided with bearing housing nut and tightening nut, the bearing construction section leading portion of described pump shaft is provided with bearing housing nut thread section, back segment is provided with tightening nut thread section, described bearing housing nut is threaded with the bearing housing nut thread section of pump shaft through bearing gland endoporus inwall, outer wall and bearing gland are tightly connected, one end and pump shaft are inconsistent, the other end and bearing bore diameter are inconsistent, the gear platform sidewall of described bearing housing nut back end is provided with hook groove, fixed hook spanner while being beneficial to dismantle, reach effect for convenience detach, described tightening nut is connected rear with tightening nut thread section and the bearing the other end is inconsistent.
Bearing housing nut thread section of the present invention is identical with the sense of rotation of pump shaft with the thread rotary orientation on tightening nut thread section, has the function of self-locking to reach when rotation, has fixed the axial position of bearing.
The present invention is owing to adopting said structure, has rational in infrastructure, easy to operate, time saving and energy saving, the advantage such as fragile bearing not.
accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
Reference character: pump shaft 1, bearing housing nut 2, bearing gland 3, bearing 4, bearing support 5, tightening nut 6, bearing housing nut thread section 7, tightening nut thread section 8.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of bearing dismantling structure, comprise pump shaft 1, bearing 4, bearing support 5 and bearing gland 3, bearing support 5 and bearing gland 3 are enclosed within respectively on pump shaft 1, bearing gland 3 is fixedly connected with bearing support 5, in bearing support 5, be provided with bearing 4, bearing 4 is fixed on the bearing construction section of pump shaft 1, it is characterized in that being provided with bearing housing nut 2 and tightening nut 6, the bearing construction section leading portion of described pump shaft 1 is provided with bearing housing nut thread section 7, back segment is provided with tightening nut thread section 8, described bearing housing nut 2 is threaded with the bearing housing nut thread section of pump shaft 1 through bearing gland 3 endoporus inwalls, outer wall and bearing gland 3 are tightly connected, one end and pump shaft 1 are inconsistent, the other end and bearing 4 internal diameters are inconsistent, the gear platform sidewall of described bearing housing nut 2 rear ends is provided with hook groove, fixed hook spanner while being beneficial to dismantle, reach effect for convenience detach, described tightening nut 6 is connected rear with tightening nut thread section and bearing 4 the other ends are inconsistent.
Bearing housing nut thread section 7 of the present invention is identical with the sense of rotation of pump shaft 1 with the thread rotary orientation on tightening nut thread section 8, has the function of self-locking to reach when rotation, has fixed the axial position of bearing.
When the present invention need to dismantle bearing 4 at replacing pump body part, with Hook wrench, catch on the hook groove of bearing housing nut 2 sidewalls, running shaft bearing sleeve nut 2, bearing housing nut 2 is axially released bearing 4 along pump shaft, facilitated dismounting, pump shaft 1 is when operation, because thread rotary orientation is identical, when bearing housing nut 2 rotates like this, there is auto-lock function, guaranteed the fixed position of bearing 4.
The present invention is owing to adopting said structure, has rational in infrastructure, easy to operate, time saving and energy saving, the advantage such as fragile bearing not.
