Abstract
A kind of structure of micro motor bearing chamber, including casing and the end that casing side is arranged in, shaft runs through casing and end, outer rotor is fixed in casing, end is a " T " shape structure, and inner stator is fixed on end, is set with outer bearing between the outside and shaft of end, two sides on end positioned at inner stator are respectively arranged with encapsulating block, and the bearing chamber of installation inner bearing is offered on the encapsulating block of the inside of end.Present invention omits steel sleeve structures, it can be not only used for small outer-rotor type motor, it can also be applied in all miniature all kinds of motors, it is required especially suitable for performance indicator high, in the restricted all types of motors of volume especially diametrical direction, keep the electric machine structure under same or similar size condition more reasonable, effective volume increases.
Description
Technical field
The present invention relates to a kind of bearing chambers of micro machine, and in particular to a kind of structure of micro motor bearing chamber.
Background technique
Outer-rotor structure motor is usually that steel bushing or copper sheathing are inserted in electric machine stator iron inner hole at present, in steel bushing or copper
Bearing chamber is processed in the inner hole of set, is used for fixing bearing outer ring, has an axis to pass through steel bushing inner hole, and and bearing in steel bushing
Inner ring cooperation, as shaft, which supports motor outer rotor.The outer rotor micro electric for only having 16mm due to needing to design outer diameter
Machine, and motor has the requirement to work under circumstances, and deep groove ball bearing can only be selected in the selection of bearing, so in electricity
There is no enough spaces to place steel bushing in the structure design of machine.
Summary of the invention
The purpose of the present invention is to provide a kind of structure is simple, steel sleeve structure is omitted, the space that can will be saved
For the effective dimensions of motor, the performance indicator of motor is improved, keeps electric machine structure more reasonable, the micro machine that effective volume increases
The structure of bearing chamber.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: including casing and the end that casing side is arranged in,
Shaft runs through casing and end, and outer rotor is fixed in casing, and end is a " T " shape structure, and is fixed on end default
Son is set with outer bearing between the outside and shaft of end, and the two sides on end positioned at inner stator are respectively arranged with encapsulating block, and
The bearing chamber of installation inner bearing is offered on the encapsulating block of the inside of end.
Encapsulating block of the invention is made of Embedding Material or die-casting material.
Present invention omits steel sleeve structures, can be not only used for small outer-rotor type motor, can also be applied to all miniature
All kinds of motors in, required especially suitable for performance indicator it is high, in the restricted all types of motors of volume especially diametrical direction,
Keep the electric machine structure under same or similar size condition more reasonable, effective volume increases.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention.
Specific embodiment
Xia Mianjiehefutuduibenfamingjiegouyuanlihegongzuoyuanlizuojinyibuxiangxishuoming.
Referring to Fig. 1, the present invention includes casing 1 and the end 2 that casing side is arranged in, and shaft 3 runs through casing 1 and end 2,
Outer rotor 4 is fixed in casing 1, end 2 is a " T " shape structure, and inner stator 5 is fixed on end 2, the outside of end 2
Outer bearing 6 is set between shaft 3, the two sides on end 2 positioned at inner stator 5 are respectively arranged with Embedding Material or die-casting material
Encapsulating block 7 is made, and offers the bearing chamber of installation inner bearing 8 on the encapsulating block 7 of the inside of end 2.
Assembling process of the invention is as follows: being fixed with the casing 1 of outer rotor 4 firstly, bearing 3 is passed through, then takes and machine
The end 2 for the " T " shape structure that shell 1 matches, and inner stator is fixed on end 2, the two of inner stator 5 is located on end 2
Side is respectively arranged with Embedding Material or encapsulating block 7 is made in die-casting material, and inner stator 5 and end is made to become an entirety, then by end
The bearing chamber of installation inner bearing 8 is opened up out on the encapsulating block 7 of the inside in portion 2, and end 2 is finally passed through into shaft 3 and casing 1 is fixed
It is integrated, the inner bearing 8 and outer bearing 6 and shaft 3 of end fasten.
The application of the structure makes motor effective volume increase 15%, and the performance indicator of motor, which improves, is greater than 10%, has simultaneously
Conducive to the protection of motor, which can effectively solve the storage problem of motor in the presence of a harsh environment, be small outer-rotor type motor
Raising performance open new road.
