Abstract

The utility model discloses an end cover of motor belongs to the motor accessory field, bearing frame on end cover body and end cover body is provided with the cover and establishes the gasket in the insulation of bearing frame excircle on the terminal surface of end cover body. Adopt this end cover of motor to avoid the friction between the interior terminal surface of coil and rear end cap and result in the enameled wire wearing and tearing, play insulating effect simultaneously.

Description

A kind of electric motor end cap
Technical field
The utility model relates to motor accessory field, in particular to a kind of electric motor end cap.
Background technology
Electric motor end cap is used to fixing or support stator and rotor vitals, and most of motor is connected by the bearing pedestal cylindrical of electric motor end cap and the inner circle of stator core to locate, stator core is wound with coil, like this after end cap installs, motor is in Long-Time Service process, coil on the inner face of electric motor end cap and stator core can rub, cause the wearing and tearing of coil varnish envelope curve surface insulation layer, easily cause short circuit, electric leakage etc., there is potential safety hazard, motor cannot be run, reduce the useful life of motor.
Utility model content
The purpose of this utility model is to provide a kind of electric motor end cap, to solve the problem that existing electric motor end cap easily causes coil varnish envelope curve surface insulation layer to wear and tear.
For realizing the utility model object, the technical scheme of employing is: a kind of electric motor end cap, comprises the bearing pedestal on end cap body and end cap body, the end face of end cap body is provided with the pad of the insulation being set in bearing pedestal cylindrical.
Further, described pad is polytetrafluoroethylene.
Further, the inner circle of described pad and the cylindrical interference fit of bearing pedestal.
Further, described end cap body is provided with installing hole, pad offers the installation corresponding with described installing hole and dodge hole.
Further, the inner face of described end cap body is provided with the positioning boss coordinated with electric machine casing inner headed face.
Further, the external diameter of described pad and the external diameter of positioning boss match.
Further, described end cap body offers fairlead, pad offers the lead-in wire corresponding with fairlead and dodges hole.
Further, sheath is arranged with in described fairlead.
Further, the two ends of described sheath are equipped with flange flange.
The beneficial effects of the utility model are, after electric motor end cap is installed, the pad of the insulation that its inner face is arranged, avoid the friction between coil and rear end cap inner face and cause enamelled wire to wear and tear, play insulating effect simultaneously, avoid potential safety hazard, prevent from causing motor to run because of enamelled wire wearing and tearing, and employing teflon gasket, its coefficient of friction is low, there is stronger high-lubricity, high and low temperature resistance, corrosion resistance and weatherability, processing technology is simpler, cost of manufacture is low, and be applicable to common electric machine and aviation field motor.
Accompanying drawing explanation
Fig. 1 is the front view of the electric motor end cap that the utility model provides;
Fig. 2 is the vertical view of the end cap body that the utility model provides;
Fig. 3 is that the electric motor end cap that provides of the utility model is as structural representation during rear end cap.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1, Fig. 2, Fig. 3 show the electric motor end cap that the utility model provides, and comprise the bearing pedestal 2 on end cap body 1 and end cap body 1, the end face of end cap body 1 are provided with the pad 3 of the insulation being set in bearing pedestal 2 cylindrical.
Pad 3 is polytetrafluoroethylene, has excellent corrosion resistance, good self lubricity and adhesion, and there is wear-resisting, withstand voltage, insulation, the characteristic such as coefficient of friction is low, well play insulation and abrasionproof effect, safe and reliable.
The inner circle of pad 3 and the cylindrical interference fit of bearing pedestal 2, pad 3 is made to be positioned end cap inner face by interference fit, after end cap body 1 is mounted to motor, towards outside motor is outer face, towards motor internal is inner face, this electric motor end cap can be provided with at the inner face of end cap body 1 positioning boss 4 coordinated with electric machine casing inner headed face, the external diameter of pad 3 and the external diameter of positioning boss match, coordinating between the cylindrical of inner face top chock 2 and the inner circle of motor stator realizes locating accurately, positioning boss 4 plays coarse positioning effect when end cap is installed, and strengthen the bonding strength effect of motor internal, the bulk strength of motor is increased.
End cap body 1 is provided with installing hole 5, pad 3 offers the installation corresponding with installing hole 5 and dodge hole.During rear end cap as motor, end cap body 1 offers fairlead 6, pad 3 offers the lead-in wire corresponding with fairlead 6 and dodge hole, can block in fairlead 6 and establish sheath, to protect the lead-out wire of motor injury-free.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
