Abstract
The insulation system of motor non-shaft stretching end shaft current is reduced the utility model discloses a kind of, it includes axle, bearing and end cap, bearing is provided between the end cap and the axle, the both sides of the bearing are separately installed with internal bearing cover and bearing end cover, the bearing end cover is arranged at outside the non-shaft stretching end of the axle, wherein, in being provided with bearing holder (housing, cover) outside the bearing between the internal bearing cover and bearing end cover, insulation sleeve is arranged between the bearing holder (housing, cover) and the end cap, the both sides of the end cap are provided with insulation board.The insulation system of above-mentioned reduction motor non-shaft stretching end shaft current is all isolated on the face being connected with end cap with insulation board, insulation sleeve.Prevent shaft current from damaging bearing, it is to avoid induced-current is to the galvanic action of bearing, the damage for preventing electric current from being caused to lubricating grease and rolling element, raceway, improve the service life of bearing.Manufacturing cost is low, and Assembly And Disassembly is convenient, is conducive to the maintenance of bearing.
Description
Technical field
The utility model belongs to motor manufacturing technology, and the insulation of motor non-shaft stretching end shaft current is reduced more particularly, to a kind of
Structure.
Background technology
In the design process of motor, in order to reduce the shaft current of motor non-shaft stretching end, it will typically add in non-shaft stretching end
Fill insulation system.Conventional insulation system is to install insulation bearing additional at present, but insulation bearing is expensive, is general bearing valency
20 times or so of lattice；Market resource is few, and delivery cycle is long, meets emergency and changes more difficult；And in Assembly And Disassembly process
In coating is easily drawn bad, be unfavorable for bearing maintenance maintenance.
Utility model content
The purpose of this utility model be to provide it is a kind of reduce the insulation system of motor non-shaft stretching end shaft current, it has into
The characteristics of this low and insulation effect is good, is deposited with solving motor non-shaft stretching end in the prior art using insulation bearing to reduce shaft current
Above mentioned problem.
For up to this purpose, the utility model uses following technical scheme：
A kind of to reduce the insulation system of motor non-shaft stretching end shaft current, it includes axle, bearing and end cap, the end cap and institute
State and be provided with bearing between axle, the both sides of the bearing are separately installed with internal bearing cover and bearing end cover, and the bearing end cover is set
Outside the non-shaft stretching end for being placed in the axle, wherein, in being provided with bearing outside the bearing between the internal bearing cover and bearing end cover
Set, is arranged at insulation sleeve, the both sides of the end cap are provided with insulation board between the bearing holder (housing, cover) and the end cap.
Especially, the internal bearing cover, bearing end cover are fixedly connected with end cap by fixing bolt, outside the fixing bolt
It is cased with insulation tube.
Especially, the section of the bearing holder (housing, cover) is T-shape structure, and correspondence offers logical on the bearing holder (housing, cover) and insulation board
Hole, the fixing bolt is set through the bearing holder (housing, cover) and insulation board.
Especially, external diameter identical stage portion, the axle are correspondingly arranged on the inside of the internal bearing cover and bearing end cover
The lateral wall held and the step surface of the stage portion are in the same plane, and the bearing holder (housing, cover) is arranged in the stage portion.
The beneficial effects of the utility model are, described compared with prior art to reduce the insulation of motor non-shaft stretching end shaft current
Structure is all isolated on the face being connected with end cap with insulation board, insulation sleeve, and fixing bolt is got up with insulative pipe sleeve, is thus made
Insulated between bearing and end cap, same effect is reached with insulation bearing.Prevent shaft current from damaging bearing, it is to avoid induced-current pair
The galvanic action of bearing, the damage for preventing electric current from being caused to lubricating grease and rolling element, raceway improves the service life of bearing.System
Low, an Assembly And Disassembly convenience is caused, is conducive to the maintenance of bearing.
