Abstract
The invention provides a submersible motor with an angular contact ball bearing capable of rapidly disassembled. The submersible motor comprises rotors, stators, an upper end cover and a lower end cover. Upper bearings are installed in a bearing chamber of the upper end cover. A circular through hole is formed in the lower end cover. A bearing chamber is arranged above the circular through hole and provided with the angular contact ball bearing. The angular contact ball bearing comprises an outer ring, a rolling ball and an inner ring. An annular boss is installed at the bottom of the bearing chamber of the lower end cover. The outer ring of the angular contact ball bearing makes contact with and is matched with the annular boss. The width of the boss is smaller than that of the outer ring of the angular contact ball bearing. A cavity is formed between the bottom of the bearing chamber of the lower end cover and the circular through hole of the lower end cover. According to the height of the cavity, a metal rod can be inserted into the circular through hole in an inclined mode and acts on the outer ring of the angular contact ball bearing. Therefore, one screwdriver or other rod-shaped tools can be inserted into the circular through hole in an inclined mode and act on the outer ring of the angular contact ball bearing, and the outer ring of the angular contact ball bearing can be rapidly taken out of the bearing chamber.
Description
Technical field
The present invention 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, during dismounting, inner ring, ball and retainer are easily separated 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.
Summary of the invention
The technical problem to be solved in the present invention 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, technical scheme of the present invention 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 when 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, around outer ring, upwards firmly push up, 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the A part enlarged diagram of Fig. 1.
Embodiment
As shown in Figure 1, 2, the preferred embodiments of the present invention are: 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.
When 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, around outer ring, 7 upwards firmly push up, and just can very soon the outer ring of angular contact ball bearing 7 be taken out from bearing chamber.
