Abstract
The utility model is related to a kind of motors with seal assembly, including shaft, rotor core assembly and stator core assembly, the rotor core assembly is fixed on the middle part of the shaft and is rotated synchronously with shaft, and the stator core assembly is fixed on the periphery of the rotor core assembly；The both ends of the shaft are equipped with through bearing cap equipped with bearing, and the bearing cap is equipped with the end cap by the bearing package in bearing cap close to the one side of the roller end；The roller end, which corresponds to, is equipped with sealing element at position of the end cap away from the bearing cap one side, the sealing element be sleeved in the shaft and with shaft rotate synchronously cyclic structure, and the sealing element be rotatably plugged on the end cap after form the seal clearance constantly bent between the two.The beneficial effects of the utility model are：Good seal performance prevents foreign matter from entering at rotor core assembly and stator core assembly the damage for causing motor.
Description
Technical field
The utility model is related to motor fields, and in particular to a kind of motor with seal assembly.
Background technology
The rotor core assembly and stator core component external of motor need good seal, otherwise shaft meeting during rotation
It brings the foreign matters such as chip, dust or water into, the normal operation of motor or even damage motor can be influenced.Currently used sealing is done
Method is generally sealed using sealing ring, which can gradually lose with the rotary seal performance of shaft, cause abnormal shape
The appearance of condition.
Utility model content
In conclusion for overcome the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide one kind
Motor with seal assembly.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of motor with seal assembly, including
Shaft, rotor core assembly and stator core assembly, the rotor core assembly are fixed on the middle part of the shaft and synchronously turn with shaft
Dynamic, the stator core assembly is fixed on the periphery of the rotor core assembly；The both ends of the shaft are equipped with and are equipped with by bearing cap
Bearing, the bearing cap are equipped with the end cap by the bearing package in bearing cap close to the one side of the roller end；It is described
Roller end, which corresponds to, is equipped with sealing element at position of the end cap away from the bearing cap one side, the sealing element is is sleeved on
It states in shaft and with the cyclic structure that shaft rotates synchronously, and the sealing element is rotatably plugged on the end cap rear two
The seal clearance constantly bent is formed between person.
The beneficial effects of the utility model are：Good seal performance prevents foreign matter from entering rotor core assembly and stator core group
The damage of motor is caused at part.
Based on the above technical solutions, the utility model can also do following improvement：
Further, the side of the sealing element is equipped with the circular pillar of a circle, and the position that the end cap corresponds to the pillar is set
There is the groove that a circle supplies its rotation.
Advantageous effect using above-mentioned further scheme is：Realize that sealing element is rotatably plugged on end cap.
Further, gap is left in the bottom of the pillar and the groove, which forms the cavity of temporary foreign matter.
Advantageous effect using above-mentioned further scheme is：Guiding foreign matter enters in cavity without to rotor core assembly and calmly
Sub- core assembly movement, and thrown away with the rotation foreign matter of sealing element out of cavity.
Description of the drawings
Fig. 1 is the utility model structure diagram.
In attached drawing, parts list represented by the reference numerals is as follows：
1st, shaft, 2, rotor core assembly, 3, stator core assembly, 4, bearing (ball) cover, 5, bearing, 6, end cap, 7, sealing element, 8,
Pillar, 9, cavity.
Specific embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of motor with seal assembly, including shaft 1, rotor core assembly 2 and stator core assembly 3,
The rotor core assembly 2 is fixed on the middle part of the shaft 1 and is rotated synchronously with shaft 1, and the stator core assembly 3 is fixed on institute
State the periphery of rotor core assembly 2；The both ends of the shaft 1 are equipped with through bearing cap 4 equipped with bearing 5, and the bearing cap 4 is close to institute
The one side for stating 1 end of shaft is equipped with the end cap 6 being encapsulated in the bearing 5 in bearing cap 4；Described in 1 end of shaft corresponds to
Be equipped with sealing element 7 at position of the end cap 6 away from 4 one side of bearing cap, the sealing element 7 to be sleeved in the shaft 1 and
With shaft 1 rotate synchronously cyclic structure, and the sealing element 7 be rotatably plugged on the end cap 6 after between the two
Form the seal clearance constantly bent.It is specific as follows：The side of the sealing element 7 is equipped with the circular pillar 8 of a circle, the end cap 6
The position of the corresponding pillar 8 is equipped with groove of the circle for its rotation.Gap is left in the bottom of the pillar 8 and the groove,
The gap forms the cavity 9 of temporary foreign matter.
Using above-mentioned 6 structure of sealing element and turn with mode, on the one hand, sealing element 6 is rotated synchronously with shaft 1, is being sealed
Foreign matter is more not easy to traverse at rotor core assembly 2 and stator core assembly 3 under the stop of 6 rotary force of part；On the other hand, seal
The seal clearance constantly bent is formed between part 6 and end cap 6, even if after foreign matter passes through sealing element 6, in close what is constantly bent
Envelope is also not easily accessed in gap at rotor core assembly 2 and stator core assembly 3, and with the rotation foreign matter meeting of sealing element 6
It throws away to outside gap.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within new spirit and principle, any modifications, equivalent replacements and improvements are made should be included in the guarantor of the utility model
Within the scope of shield.
