The utility model discloses have the axiality locate function, and can effectively solve the phenomenon of blocking when the ripple gasket is installed.
Description
Technical field
The utility model relates to the parts of motor, particularly a kind of electric motor end cap.
Background technology
The performance of motor and quality, not only depend on correct design parameter, and simultaneously the crudy of parts, assembly quality play a part to the final performance of motor feeling property.As the end cap of one of the major part of motor, be the strength member rotated by installing bearing supporting motor rotor, its machining accuracy and assembly precision play a part key to the noise of motor, even running, motor performance.
In order to control axial endplay and the running noise reduced because bearing own backlash causes of rotor and beat, reach the object reducing noise, even running, effective solution installs corrugated gasket additional in end-cover axle bearing indoor, is out of shape to bearing pretightning force by corrugated gasket.But traditional end-cover axle bearing room has a step at rear portion; when loading corrugated gasket; corrugated gasket often can be blocked by this step; need that operating personnel are each to be confirmed; adjust the Corrugation pad blocked, this phenomenon not only have impact on the fluency of production greatly, and also cannot confirm whether Corrugation pad after assembling is again mobile; impact production efficiency, there is again quality risk (see Fig. 2) simultaneously.
Utility model content
The purpose of this utility model be to provide a kind of there is axiality positioning function and can effectively solve corrugated gasket install time stuck phenomenon electric motor end cap.
The technical scheme realizing the utility model object is: the utility model has body, and body is provided with end-cover axle bearing room; Described end-cover axle bearing room comprises annular side, the annular bottom surface vertical with annular side and forms the bullet pad doughnut of transition with annular bottom surface; The bottom center of described bullet pad doughnut is provided with wears axis hole; The sidewall that described bullet pad doughnut is connected with annular bottom surface transition is taper seat; Described bullet pad doughnut is circular cone shape, and sidewall closes up to wearing axis hole end; Described annular side, annular bottom surface, bullet pad doughnut and to wear axis hole all coaxial.
The whole bottom surface of above-mentioned bullet pad doughnut is for wearing axis hole; The described sidewall worn between axis hole and annular bottom surface is taper seat.
The angle of the sidewall that above-mentioned bullet pad doughnut is connected with annular bottom surface transition and annular bottom surface is 20 °.
The inner side end of above-mentioned body is provided with coaxial positioning block group; Described coaxial positioning block group comprises two or more and to wear axis hole concentric, and to wear the arc locating piece that axis hole circumference is equally spaced; Described arc locating piece is positioned at the edge of inner side end.
Upper described each arc locating piece is equipped with connecting through hole.
Above-mentioned coaxial positioning block comprises four arc locating pieces.
The utility model has positive effect: (1) the utility model sidewall of being connected with annular bottom surface transition of pad doughnut of being hit by a bullet is taper seat, solves the problem that corrugated gasket easily blocks when installation corrugated gasket, improves installation rate; (2) the utility model is hit by a bullet the pad sidewall of doughnut and the angle of annular bottom surface when being 20 °, and result of use is best; (3) by arc locating piece, the utility model can ensure that the stator of electric motor end cap and motor, rotor and rotating shaft are coaxial, thus the air gap ensureing rotor and stator evenly, realizes the optimum of motor performance.
