Abstract
Provided is a rabbet cooperating structure between a motor base and end covers. The rabbet cooperating structure comprises a motor base and the end covers. The motor base and the end covers are in taper rabbet cooperation. Joints of the motor base and end cover rabbets have certain conical degree, so interference fit between the motor base and the end cover rabbets is realized, and problems that coaxiality deviation of each round surface on the motor base and the end covers is large caused by radial clearances are prevented. Tensioning pull rods between the motor base and the end covers are sleeved with insulating bushes for insulation, thereby reducing loss inside the pull rods, preventing looseness between the motor base and the end covers caused by extension of heated pull rods, and being beneficial for prolonging life of a motor.
Description
Technical field
The utility model belongs to technical field of motors, is specifically related to a kind of support of motor and the seam fit structure between end cap.
Background technology
Face of cylinder seam is adopted in cooperating between present motor, support and end cap, and for excessively to cooperate, such structure often causes on support, the end cap each disc coaxiality deviation big between support and end cap seam; Simultaneously, the tension pull bar between support and end cap does not have insulation measures, and the pull bar internal loss is bigger, and easily heating causes the pull bar temperature high and extend, thereby causes between support, end cap loosening.
Summary of the invention
The purpose of this utility model is to provide the fit structure of the seam between a kind of electric machine stand and end cap, solves the support of prior art existence, the problem that the end cap coaxiality deviation is big.
The purpose of this utility model is achieved in that the seam fit structure between electric machine stand and end cap, comprises support and end cap, cooperates for the tapering seam between support and the end cap.
Characteristics of the present utility model also are:
Above-mentioned tapering seam is that the bus of support, end cap cooperation place becomes 0.5-5 ° of angle with axis.
Above-mentioned support is male half coupling, and end cap is inner stopper.
Above-mentioned end cap comprises front end housing and rear end cap; Above-mentioned support is connected by stud pull bar and nut with front end housing, rear end cap, the sheathed silicon rubber insulation sleeve pipe of stud pull bar.
Be provided with the insulation flat shim between above-mentioned nut and end cap.
The utlity model has following beneficial effect:
1, there is certain taper support of the present utility model and end cap seam junction, have realized the interference fit between support and end cap seam, cause the big problem of each disc coaxiality deviation on support, the end cap thereby avoided occurring radial clearance.
2, the sheathed insulating sleeve of tension pull bar between the utility model support and end cap insulate, and has reduced the pull bar internal loss, has avoided pull bar owing to becoming flexible between the support that caused by thermal stretching, end cap, is conducive to prolong organism life-span.
