Abstract
The object of the present invention is to provide a kind of submersible motor of easy dismounting angular contact ball bearing, technical scheme of the present invention is: comprise bearing supporting body, angular contact ball bearing, described bearing supporting body comprises bearing chamber, described angular contact ball bearing is positioned at bearing chamber, described angular contact ball bearing comprises outer ring, ball, inner ring, have at least 2 screws bottom described bearing supporting body, described screw is positioned at the corresponding angular contact ball bearing outer ring place of bearing supporting body, symmetrical in axle center.Another kind of technical scheme of the present invention is: comprise bearing supporting body, angular contact ball bearing, described bearing supporting body comprises bearing chamber, described angular contact ball bearing is positioned at bearing chamber, described angular contact ball bearing comprises outer ring, ball, inner ring, it is characterized in that: between bottom described angular contact ball bearing and bearing chamber, one piece of backing plate is housed, described backing plate has screw.Such scheme, can make the angular contact ball bearing of submersible motor be easy to dismounting, save labor, and reduces the unnecessary loss that artificial dismounting is improper caused.
Description
Technical field
The present invention relates to a kind of submersible motor.
Background technology
Bearing a kind ofly rises fixing in mechanical transmission course and reduce the parts of load coefficient of friction, alternatively, when other parts produce relative motion each other on axle, bearing can be used for reducing coefficient of friction in power transmission process and retainer shaft center is fixed.
As the one of bearing, angular contact ball bearing has more advantages relative to general bearing: structure is simple, and limit speed is higher, and moment of friction is smaller, can bear radial and axial load and running accuracy is high, noise is little simultaneously.So angular contact ball bearing is applied widely in submersible motor, be also a kind of very important parts in submersible motor, its major function is support rotor, in order to reduce the mechanical load coefficient of friction of equipment in transmission process simultaneously.
Because submersible motor is often in running order, and work under bad environment, cause angular contact ball bearing easily to wear and tear, once damage, angular contact ball bearing is changed to get up to bother very much.Because the angular contact ball bearing outer ring of existing submersible motor and bearing chamber adopt interference fits, during dismounting, inner ring, ball are easily separated with outer ring with retainer, leave outer ring carries out separately dismantling very difficult in bearing chamber, have a strong impact on operating efficiency, even likely need to change together with bearing supporting body, add unnecessary cost.
Summary of the invention
The object of the present invention is to provide a kind of submersible motor of easy dismounting angular contact ball bearing.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of submersible motor of quick detachable angular contact ball bearing, comprise bearing supporting body, angular contact ball bearing, described bearing supporting body comprises bearing chamber, described angular contact ball bearing is positioned at bearing chamber, described angular contact ball bearing comprises outer ring, ball, inner ring, has at least 2 screws bottom described bearing supporting body, and described screw is positioned at the corresponding angular contact ball bearing outer ring place of bearing supporting body.
The technical program is further improved: described screw is that axle center is symmetrical at the corresponding angular contact ball bearing outer ring place of bearing supporting body.
For solving the problems of the technologies described above, based on identical inventive concept, another kind of technical scheme of the present invention is: a kind of submersible motor of quick detachable angular contact ball bearing, comprise bearing supporting body, angular contact ball bearing, described bearing supporting body comprises bearing chamber, and described angular contact ball bearing is positioned at bearing chamber, and described angular contact ball bearing comprises outer ring, ball, inner ring, between bottom described angular contact ball bearing and bearing chamber, one piece of backing plate is housed, described backing plate has screw.
The technical program is further improved: described backing plate has 1 screw, described screw is positioned at the central point of backing plate.
The technical program another kind improves and is: described backing plate has at least 2 screws, and described screw is positioned at the corresponding angular contact ball bearing inner ring place of backing plate, symmetrical in axle center.
Adopt technique scheme, the angular contact ball bearing of submersible motor can be made to be easy to dismounting, save labor, reduce the unnecessary loss that artificial dismounting is improper caused, effectively solve the maintenance of submersible motor angular contact ball bearing, cleaning, maintenance and change the problems such as inconvenience.

When needs dismounting angular contact ball bearing 2, be screwed into sufficiently long bolt by the screw 12 in bearing supporting body 1, just angular contact ball bearing 2 outer ring 21 can be ejected bearing chamber 11.
embodiment 2:a kind of submersible motor of quick detachable angular contact ball bearing, comprise bearing supporting body 1, angular contact ball bearing 2, described bearing supporting body 1 comprises bearing chamber 11, described angular contact ball bearing 2 is positioned at bearing chamber 11, described angular contact ball bearing 2 comprises outer ring 21, ball 22, inner ring 23, between bottom described angular contact ball bearing 2 and bearing chamber 11, one piece of backing plate 3 is housed, described backing plate 3 has 1 screw 31, described screw 31 is positioned at the central point of backing plate 3.
The technical program another kind improves and is: described backing plate 3 has at least 2 screws 31, and described screw 31 is positioned at backing plate 3 corresponding angles contact ball bearing 2 inner ring 23 place, symmetrical in axle center.
When needs dismounting angular contact ball bearing 2 outer ring 21, be screwed into sufficiently long bolt by the screw 31 at backing plate 3, bolt, just can by backing plate 3 and angular contact ball bearing 2 outer ring 21 reverse ejection bearing chamber 11 by exerting oneself bottom bearing chamber 11.
