Specific embodiment
In order to be more clear goal of the invention of the invention, technical solution and its advantageous effects, below in conjunction with attached drawing
And specific embodiment, the present invention will be described in further detail；
In the accompanying drawings: a kind of bearing of the motor with anti-electrocorrosion structure, including bearing outer ring 2, bearing inner race 1, steel ball 3 are arranged
In the steel ball track that bearing outer ring 2 and bearing inner race 1 are formed, bearing outer ring 2 and 1 upper surface of bearing inner race are provided with dust-proof
Lid 5, lower end surface are provided with lower dustproof cover 6；It is characterized by: the internal circular surfaces middle position circumferential direction of the bearing outer ring 2 is set
It is equipped with the arc-shaped concave a7 to match with steel ball, several oil storages groove a8 is provided on arc-shaped concave a7, in arc-shaped concave a7
Above and below be symmetrically arranged with bayonet a9 for installing dustproof cover, lower dustproof cover；The outer circle of the bearing inner race 1
Surface middle position is arranged circumferentially the arc-shaped concave b10 to match with steel ball, is provided with several oil storages on arc-shaped concave b10
Groove b11 is symmetrically arranged with the bayonet for installing dustproof cover, lower dustproof cover above and below arc-shaped concave b10
b12；It is provided with the bearing support 13 of locking ball between bearing outer ring 2 and bearing inner race 1, steel ball holding is made to be evenly arranged on steel ball rail
In road.
The bearing support 13 is set as nylon material, including the circular ring type pedestal 14 matched with steel ball track, pedestal
Several through-holes 15 are evenly arranged on 14 with the position of locking ball, fixinig plate 16 is arranged along pedestal and matches setting with steel ball
In the two sides of through-hole 15, there are two fixinig plates 16 for each setting of steel ball 3 with the position of stationary balls, and fixinig plate 16 is set as and steel
The arc-shaped that ball matches；The upper dustproof cover 5 is identical as lower 6 structure of dustproof cover, and inner edge is provided in round and is arranged in
It is matched in the groove of bayonet b12 with bayonet b, the hook solid that outside is set as upward is matched with the groove of bayonet a9, and is set
It is set to interference fit；The full conductive lubricant grease of cavity filling formed between upper dustproof cover 5, lower dustproof cover 6 and steel ball 3；Institute
The quantity of the oil storage groove a8 stated is set greater than the even number equal to 2 and less than or equal to 8, the quantity and oil storage of oil storage groove b11
The quantity of groove a8 is equal；Oil storage groove a8 and oil storage groove b11 relative to 3 center of steel ball, 1 center of bearing inner race, bearing outside
2 central symmetries are enclosed to be evenly arranged；The section of the oil storage groove a8, oil storage groove b11 be set as rectangle, circle, it is trapezoidal or
Full conductive lubricant grease is filled in triangle, oil storage groove a8 and oil storage groove b11.
Specific implementation of the invention: by using this programme, the multiple tracks oil storage groove of setting is for storing conductive lubricating oil
Rouge, bearing inner race drive steel ball to rotate around axle center and generate centrifugal force, and grease is thrown toward steel ball track outer ring side, is being stored
Accumulation is formed after grease damping in the trench, guarantees to be deposited in steel ball track outer ring side always by the grease that throwing is got rid of in this way,
And the grease of accumulation is taken back inner ring oil storage groove and fills up periphery air gap by steel ball itself rotation, is looped back and forth like this, even if axis
The air gap for holding long-term operating steel ball and inside and outside bearing race can also be filled up by the conductive grease in oil storage groove always, to establish
As soon as playing a curved access, good low resistance conductive circuit can be formed between inside and outside bearing race and steel ball, to balance electricity
Potential difference prevents the generation of galvano-cautery phenomenon.
Bearing for motor operating all can be by the effect of rotor magnetic, and motor usually can all have spring wave washer
Presence so that bearing is by very big axial thrust up and down.Therefore oil storage groove cannot be arranged in the upper and lower center of bearing,
Otherwise it will cause one side that steel ball is biased to groove, bearing axial play increases, and steel ball, which is detached from raceway center, causes abrasion to be accelerated, axis
The axial direction held, radial dimension all cannot be guaranteed that noise can persistently increase；And the oil storage groove phase for the even number that the present invention is arranged
Steel ball center, bearing inner race center, bearing outer ring central symmetry are evenly arranged, just ensure that filling lubricant grease well
The axial thrust that steel ball is subject to afterwards is uniform, it is impossible to be detached from the center of raw steel ball track, guarantee the opposite of steel ball when bearing operation
Stablize, while oil storage groove constantly provides the supplemental lubrication of conductive grease in steel ball rotary course, the entirety for reducing bearing is made an uproar
Cent shellfish.
Above-described embodiment is only intended to clearly illustrate description made by the present invention, and does not limit the embodiments,
To those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description
Dynamic, there is no necessity and possibility to exhaust all the enbodiments, and the obvious variation or change thus amplified out
It is dynamic to be still in the protection scope of this invention.
