Abstract
The utility model provides an end cover of a motor. A shaft outlet hole (3) is formed on the end cover (1); wherein, the end cover (1) comprises a main housing (4) of the end cover, and a bearing cover (5); the main housing (4) of the end cover is provided with a hollow cavity (7); the bearing cover (5) is provided with a bearing house (10), and a convex edge (2) which extends out of two sides of the bearing house (10); and the bearing cover (5) is riveted on the bottom surface (6) of the main housing (4) of the end cover through the convex edge (2) thereon. The end cover of the utility model adopts the structure which comprises the main housing of the end cover and the bearing cover, and the two components are connected in a riveting manner, and besides, the structure of the main housing of the end cover and the structure of the bearing cover are simple and can be manufactured only through little stamping and stretching procedures, thereby solving the difficult problems that the manufacture of the prior end cover needs to pass continuous and multiple stamping and punching procedures, the association and the influence between the previous procedure and the following procedure are strong, and the quality is not steady; a riveted end cover has little residual stress and is easy to be released; compared with the prior end cover, the precision of the coaxiality of the main housing of the end cover and the bearing cover are greatly increased; and by using the motor assembled by the end cover of the utility model, the noise is greatly reduced.
Description
Technical field
The utility model is a kind of electric motor end cap, and particularly a kind of low noise electric motor end cap that is used for small-power iron-clad motor belongs to the renovation technique of electric motor end cap.
Background technology
The existing electric motor end cap that is used for small-power iron-clad motor adopts repeatedly punching stretch usually, monolithic molding, its structural representation as shown in Figure 1, 2, stretching end cap 1 set bearing chamber 10 and hollow cavity 7 is to finish making through the continuous punching stretch of multiple operation, residual stress is big.Be divided into two kinds of in-draw end cap and out-draw end caps by the stretching structure difference.Realize the required precision of this class end cap each several part size, place one's entire reliance upon and make the punching stretch mould and die accuracy and the raw-material stability of end cap.The operation of this class formation end cap punching stretch is more, all will influence the dimensional accuracy of shaping end cap unusually when the mould existence of one of them operation.In addition, owing to be that the multiple operation punching stretch is made,, all will make a big impact to the final size that is shaped of end cap as long as material behavior has very little fluctuation.Motor product quality stability with this structure end cap assembling is poor.
The utility model content
The purpose of this utility model is to consider the problems referred to above and provides a kind of manufacturing procedure simple, the upper and lower operation less electric motor end cap that influences each other.The utility model still can be guaranteed its quality when raw-material material behavior fluctuation is big.Can improve simultaneously the quality stability of assembling motor.
The technical solution of the utility model is: end cap is provided with out axis hole, wherein end cap includes end cap main casing and bearing cap, the end cap main casing has been made hollow cavity, bearing cap makes bearing chamber and to the overhanging chimb in bearing chamber both sides, bearing cap is riveted on the bottom surface of end cap main casing by its set chimb.
Riveted joint between the bottom surface of set chimb of above-mentioned bearing cap and end cap main casing is by the riveted joint of some riveting points.
Above-mentioned bearing cap places the inside of the hollow cavity that the end cap main casing makes, or bearing cap places the outside of the hollow cavity that the end cap main casing makes.
Made positioning step on the bottom surface of above-mentioned end cap main casing.
Above-mentionedly go out axis hole and be arranged on the bottom surface of end cap main casing, or be arranged on the bottom surface of bearing cap.
The workpiece body riveting is adopted in above-mentioned riveting point, or rivet class securing member.
The quantity of above-mentioned riveting point is 2～8.
End cap of the present utility model is because employing includes end cap main casing and bearing cap, and the structure that two members connect by riveted, wherein end cap main casing and bearing cap are simple in structure, only need and can finish making by less punching stretch operation, having solved existing end cap making needs through continuous multiple operation punching stretch, on, the association influence of following inter process is big, the unsettled difficult problem of quality, end cap residual stress behind the riveted is little, and easily discharge, the existing end cap of the coaxial accuracy of end cap main casing and bearing cap improves a lot, and uses the noise of motor of the utility model end cap assembling obviously to reduce.The utility model is that a kind of design is ingenious, function admirable, convenient and practical electric motor end cap.
