Description

A kind of electric motor end cap and casing assembly structure

Technical field:

The utility model relates to a kind of electric motor end cap and casing assembly structure.

Background technology:

Traditional electric motor end cap and casing assembly structure; Mainly be to lean on the end cap edge surface contact with casing inner wall, the while offers seam and supports end cap in the casing end, and this structure causes end cap and casing concentricity poor; Thereby the noise that causes motor is big, vibration is big; The assembling consistency is poor, even causes rotor to rub mutually with stator, and rotor can't normal rotation.

Summary of the invention:

The purpose of the utility model provides a kind of electric motor end cap and casing assembly structure, and this is simple in structure, guarantees the concentricity of casing and end cap, reduces noise, reduces vibration, and the assembling high conformity guarantees that motor normally moves.

The purpose of the utility model is achieved through following technical proposals.

A kind of electric motor end cap and casing assembly structure comprise casing and end cap, and casing and end cap are installed and connected; Be provided with the cavity that stator module and rotor assembly are installed in the middle of the casing; End cap comprises body, is provided with bearings mounted bearing chamber in the middle of the body, and the body outer ledge of end cap folds some flange downwards; Flange embeds in the cavity of casing, and the lateral surface of flange is close to casing inner wall face end.

Above-mentioned described between adjacent two flange, the body of end cap outside protrusion lug, lugs support is on the casing end face.

Above-mentioned described casing is a cylindrical shape, annular inner wall face during the casing end, and casing and end cap are welded to connect together.

Above-mentioned described casing end face is the plane.

Above-mentioned described some flange are 4, and lug also is 4, is distributed on the body.

Above-mentioned described end cap is stamping forming.

The utility model compared with prior art has following effect: the 1) contact area of the utility model increase and casing, adopt end cap flange and casing inner wall tight fit; This is simple in structure, guarantees the concentricity of casing and end cap, reduces noise; Reduce vibration, the assembling high conformity; 2) casing is a cylindrical shape, annular inner wall face during the casing end, and casing and end cap are welded to connect together, and the casing end face is the plane, reduces motor case end seam, guarantees casing end circularity, thereby improves assembly precision and efficient; 3) between adjacent two flange, the body of end cap outside protrusion lug, lugs support is on the casing end face, moving axially of restriction end cap improves installation effectiveness; Some flange are 4, and lug also is 4, are distributed on the body, and are stressed even, guarantee that end cap is fastened on the casing.

Embodiment:

Below through specific embodiment and combine accompanying drawing that the utility model is described in further detail.

Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; A kind of electric motor end cap of the utility model and casing assembly structure comprise casing 1 and end cap 2, and casing 1 is installed with end cap 2 and connected; Be provided with the cavity 11 that stator module and rotor assembly are installed in the middle of the casing 1; End cap 2 comprises body 21, is provided with bearings mounted bearing chamber 22 in the middle of the body 21, and body 21 outer ledges of end cap 2 fold some flange 23 downwards; 11 li of the cavitys of flange 23 embedding casings 1, the lateral surface of flange 23 is close to casing 1 internal face end; Between adjacent two flange 23, body 21 outsides of end cap 1 protrusion lug 24, lug 24 is bearing on casing 1 end face; Described casing 1 is a cylindrical shape, annular inner wall face during casing 1 end, and casing 1 is welded to connect together with end cap 2; Casing 1 end face is the plane; Some flange 23 are 4, and lug 24 also is 4, are distributed on the body 21; Described end cap 2 is stamping forming.

Body 21 outer ledges of the utility model end cap 2 fold some flange 23 downwards; 11 li of the cavitys of flange 23 embedding casings 1; The lateral surface of flange 23 is close to casing 1 internal face end; Reduce the seam of casing 1 end face simultaneously, effectively solve because the problem of casing 1 and end cap 2 decentraction, thereby solve big, the bad problems such as vibration is big, assembling consistency difference of noise that motor such as doffer such as series such as 82/94 grade exists for a long time always; The utility model is applicable to installs ball bearing or two kinds of end cover structures of oiliness bearing, stretching end cap and cylinder casing connecting structure, ventilation motor and two kinds of structures of sealing motor.
