Abstract
The utility model will provide a kind of submersible motor that can fast dismantle angular contact ball bearing, comprise rotor, stator, upper end cover, bottom end cover, in upper end cover bearing chamber, upper bearing (metal) is housed, bottom end cover is provided with manhole, manhole top is provided with bearing chamber, angular contact ball bearing is housed in bearing chamber, and described angular contact ball bearing comprises outer ring, ball, inner ring; The bottom of described bottom end cover bearing chamber is an annular boss, and angular contact ball bearing outer ring contacts cooperation with annular boss, and the width of described boss is less than the width of described angular contact ball bearing outer ring; Between the bottom of bottom end cover bearing chamber and the manhole of bottom end cover, be also provided with a cavity, the height of described cavity can allow the oblique insertion acting on angular contact ball bearing outer ring from manhole of a Metallic rod.So just can, with the oblique insertion acting on angular contact ball bearing outer ring from manhole of a screwdriver or other rod tool, very soon the outer ring of angular contact ball bearing be taken out from bearing chamber.
Description
Technical field
The utility model relates to a kind of submersible motor, specifically, is a kind of submersible motor that angular contact ball bearing is housed.
Background technology
Angular contact ball bearing is simple in structure for general bearing, 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 it is very extensive that angular contact ball bearing is applied in submersible motor, 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 works under water, work under bad environment, once motor entering water, angular contact ball bearing is owing to losing lubricated easily wearing and tearing, once 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, when dismounting, inner ring, ball and retainer easily separate with outer ring, leave 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.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of submersible motor that can quick-detachment angular contact ball bearing.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of submersible motor that can fast dismantle angular contact ball bearing, comprise rotor, stator, upper end cover, bottom end cover, in upper end cover bearing chamber, upper bearing (metal) is housed, bottom end cover is provided with manhole, manhole top is provided with bearing chamber, and angular contact ball bearing is housed in bearing chamber, and described angular contact ball bearing comprises outer ring, ball, inner ring; The bottom of described bottom end cover bearing chamber is an annular boss, and angular contact ball bearing outer ring contacts cooperation with annular boss, and the width of described boss is less than the width of described angular contact ball bearing outer ring; Between the bottom of bottom end cover bearing chamber and the manhole of bottom end cover, be also provided with a cavity, the height of described cavity can allow the oblique insertion acting on angular contact ball bearing outer ring from manhole of a Metallic rod.
Technique scheme, because the width of boss is less than the width of described angular contact ball bearing outer ring, and between the bottom of bottom end cover bearing chamber and the manhole of bottom end cover, be also provided with a cavity, the height of described cavity can allow the oblique insertion acting on angular contact ball bearing outer ring from manhole of a Metallic rod, so just can be in the time of the better angular contact ball bearing of needs, first armature spindle is extracted from the bearing chamber of bottom end cover together with inner ring and the ball of angular contact ball bearing, leave outer ring in bearing chamber, again with one the oblique insertion acting on angular contact ball bearing outer ring from manhole of screwdriver or other rod tool, upwards firmly push up around outer ring, just can very soon the outer ring of angular contact ball bearing be taken out from bearing chamber.Whole process is time saving and energy saving, and reduces improper the caused unnecessary loss of artificial dismounting, effectively solves maintenance, cleaning, the maintenance of submersible motor angular contact ball bearing and changes the problems such as inconvenience.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A part enlarged diagram of Fig. 1.
Embodiment
As shown in Figure 1, 2, preferred embodiment of the present utility model is: a kind of submersible motor that can fast dismantle angular contact ball bearing, comprise rotor 4, stator 3, upper end cover 1, bottom end cover 5, armature spindle 6, in upper end cover 1 bearing chamber, upper bearing (metal) 2 is housed, bottom end cover 5 is provided with manhole, manhole top is provided with bearing chamber, and angular contact ball bearing is housed in bearing chamber, and described angular contact ball bearing comprises outer ring 7, ball 8, inner ring 9; The bottom of described bottom end cover 5 bearing chambers is an annular boss 10, and angular contact ball bearing outer ring 7 contacts cooperation with annular boss 10, and the width of described boss 10 is less than the width of described angular contact ball bearing outer ring 7; Between the bottom of bottom end cover 5 bearing chambers and the manhole of bottom end cover 5, be also provided with a cavity 11, the height of described cavity 11 can allow the oblique insertion acting on angular contact ball bearing outer ring 7 from manhole of a Metallic rod.
In the time that submersible motor need to be changed angular contact ball bearing, first armature spindle 6 is extracted from the bearing chamber of bottom end cover 5 together with inner ring 9 and the ball 8 of angular contact ball bearing, leave outer ring 7 in bearing chamber, again with one the oblique insertion acting on angular contact ball bearing outer ring 7 from manhole of screwdriver or other rod tool, upwards firmly push up around outer ring 7, just can very soon the outer ring of angular contact ball bearing 7 be taken out from bearing chamber.
