The front end cap (2) and the back end cap (3) are arranged at two ends of the casing (1). The motor structure is characterized in that the outer wall of the casing (1) is provided with several supports (4), each support (4) is provided with a through hole (41), several lugs (31) are convex on the edge of the back end cap (3), each lug (31) is provided with an installing hole (310), the installing holes (310) are positioned corresponding to the through holes (41), and an installation screw (5) extends out of the end surface of the back end cap (3) through the corresponding through hole (41) and the corresponding installing hole (310). According to the motor structure, the structure is simple, the kinds of materials are minimized, and production cost is reduced.

Description

A kind of electric machine structure

Technical field:

The utility model relates to a kind of electric machine structure.

Background technology:

Traditional motor, comprise casing, front end housing and rear end cap, front end housing and rear end cap are installed in the casing two ends, lock by screw bolt and nut, bolt tail protrudes nut, as connecting the external equipment part, because external equipment and bolted two through hole centre-to-centre spacing are generally 110mm or 130mm, need to use the motor of different model to different centre-to-centre spacing, use different casing, end cap, stator module and rotor assembly, material is various, and cost increases, complex structure.

Summary of the invention:

The purpose of this utility model provides a kind of electric machine structure, and it is simple in structure, reduces material variety, reduces production costs.

The utility model is to be achieved by following technical scheme.

A kind of electric machine structure, comprise casing, front end housing and rear end cap, front end housing and rear end cap are installed in the casing two ends, the casing outer wall is provided with some supports, offer through hole on the support, the rear end cap edge protrudes some lugs, and lug is provided with installing hole, installing hole and lead to the hole site are corresponding, and mounting screw is by through hole and installing hole and stretch out the rear end cap end face.

Described above near rear end cap one end, the support welding outer side surface at casing.

Lug described above and rear end cap one cast aluminium forming.

Mounting screw riveting described above is on support.

Some supports described above are 4, are distributed on the casing outer side surface.

Some lugs described above are 4, are distributed on the rear end cap.

The utility model motor stretching end cover is compared with prior art had a beneficial effect: 1) the utility model casing outer wall is provided with some supports, offer through hole on the support, the rear end cap edge protrudes some lugs, lug is provided with installing hole, installing hole and lead to the hole site are corresponding, and mounting screw is by through hole and installing hole and stretch out the rear end cap end face, and is simple in structure, reduce material variety, reduce production costs; 2) lug and rear end cap one cast aluminium forming, near rear end cap one end, the support welding outer side surface at casing, because rear end cap is cast aluminium forming, the hardness of aluminium is lower, easily distortion, steel bracket plays supporting role, prevents the cast-aluminum end cover distortion; 3) the mounting screw riveting is on support, and mounting screw connects external equipment, connects fastening.

Fig. 2 is the utility model motor side view;

Fig. 3 is the A-A phantom of Fig. 2;

Fig. 4 is the utility model motor rearview.

Embodiment:

Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one: as shown in Figures 1 to 4, the utility model is a kind of electric machine structure, comprise casing 1, front end housing 2 and rear end cap 3, front end housing 2 and rear end cap 3 are installed in casing 1 two ends, and casing 1 outer wall is provided with some supports 4, offers through hole 41 on the support 4, rear end cap 3 edges protrude some lugs 31, lug 31 is provided with installing hole 310, and installing hole 310 and through hole 41 positions are corresponding, and mounting screw 5 is by through hole 41 and installing hole 310 and stretch out rear end cap 3 end faces.

Embodiment two: the basis at embodiment one increases following technical characterictic: at the outer side surface that is welded on casing 1 near rear end cap 3 one ends, support 4.

Embodiment three: the basis at embodiment two increases following technical characterictic: lug 31 and rear end cap 3 one cast aluminium formings.

Embodiment four: the basis at embodiment one or embodiment two or embodiment three increases following technical characterictic: mounting screw 5 rivetings are on support 4.

Embodiment five: the basis at embodiment one increases following technical characterictic: described some supports 4 are 4, are distributed on casing 1 outer side surface.

Embodiment six: the basis at embodiment one increases following technical characterictic: described some lugs 31 are 4, are distributed on the rear end cap 3.

Because the application is mechanical field, the apparent association of ability those of ordinary skill obtains: the technical characterictic independent assortment of the increase that embodiment two, embodiment three, embodiment four, embodiment five and embodiment six mention is combined into new technical scheme with the technical scheme of embodiment one.

As shown in Figure 4, the diameter of a circle Φ at installing hole 310 centers is 110mm or 130mm excessively.

The utility model comprises casing 1, front end housing 2 and rear end cap 3, front end housing 2 and rear end cap 3 are installed in casing 1 two ends, casing 1 outer wall is provided with some supports 4, offer through hole 41 on the support 4, rear end cap 3 edges protrude some lugs 31, lug 31 is provided with installing hole 310, installing hole 310 and through hole 41 positions are corresponding, mounting screw 5 is by through hole 41 and installing hole 310 and stretch out rear end cap 3 end faces, solve the different centre-to-centre spacing of external equipment installing hole and need to use different casings, end cap, stator module and rotor assembly problem, only need change the rear end cap of different size, and are simple in structure, reduce material variety, reduce production costs.
