Abstract
The invention aims to provide a submersible motor with an easily disassembled angular contact ball bearing. The technical solution is that the submersible motor comprises a bearing support body and an angular contact ball bearing, the bearing support body comprises a bearing chamber, the angular contact ball bearing is located in the bearing chamber and comprises an outer ring, a ball and an inner ring, the bottom part of the bearing support body is provided with at least two screw holes, the screw holes are located at the bearing support body corresponding to the outer ring of the angular contact ball bearing and in axis symmetrical distribution. Another technical solution of the invention is that the submersible motor comprises a bearing support body and an angular contact ball bearing, wherein the bearing support body comprises a bearing chamber, the angular contact ball bearing is located in the bearing chamber, and the angular contact bearing comprises an outer ring, a ball and an inner ring. The submersible motor is characterized in that the angular contact bearing and the bottom part of the bearing chamber are provided with a base plate therebetween, and the base plate is provided with screw holes. The solution provided by the invention can enable the angular contact ball bearing of the submersible motor to be disassembled easily, thereby saving labor and effort, and reducing unnecessary loss caused by inappropriate artificial disassembling.
Description
Technical field
The present invention relates to a kind of submersible motor.
Background technology
Bearing is a kind of parts fixing and minimizing load coefficient of friction that rise in mechanical transmission course, also can say, when other parts produced relative motion each other on axle, coefficient of friction and retainer shaft center that bearing can be used for reducing in power transmission process were fixed.
A kind of as bearing, angular contact ball bearing has more advantages with respect to general bearing: simple in structure, limit speed is higher, and moment of friction is smaller, can bear simultaneously radial and axial load and running accuracy is high, noise is little.So angular contact ball bearing is applied in submersible motor very extensive, be also a kind of very important parts in submersible motor simultaneously, its major function is support rotor, the mechanical load coefficient of friction in order to reduction equipment in transmission process.
Because submersible motor is often in running order, and work under bad environment, cause angular contact ball bearing easily to wear and tear, in case damage, angular contact ball bearing is changed very trouble.Because the angular contact ball bearing outer ring of existing submersible motor and bearing chamber adopt interference fits, during dismounting, inner ring, ball and retainer easily separate with outer ring, staying outer ring dismantles separately very difficult in bearing chamber, have a strong impact on operating efficiency, even likely need to change together with bearing supporting body, increase 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, and described bearing supporting body bottom has at least 2 screws, and described screw is positioned at the corresponding angular contact ball bearing outer ring of bearing supporting body place.
The technical program is further improved: it is symmetrical that described screw is axle center at the corresponding angular contact ball bearing outer ring of bearing supporting body place.
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 described angular contact ball bearing and bearing chamber bottom, a backing plate is housed, on described backing plate, has screw.
The technical program is further improved: on described backing plate, have 1 screw, described screw is positioned at the central point of backing plate.
The another kind of improvement of the technical program is: on described backing plate, have at least 2 screws, described screw is positioned at the corresponding angular contact ball bearing inner ring of backing plate place, is axle center symmetrical.
Adopt technique scheme, can make the angular contact ball bearing of submersible motor be easy to dismounting, save labor, reduce the improper unnecessary loss that causes of artificial dismounting, effectively solve maintenance, cleaning, the maintenance of submersible motor angular contact ball bearing and change the problems such as inconvenient.
