Abstract

The utility model relates to a motor housing good in heat radiation and noise-reducing. The motor housing comprises a cylindrical body. One end of the cylindrical body has an end cover, the side wall of the body is of a double-layer structure, a hollow interlayer is arranged in the middle of the double-layer structure, the outer circumferential wall of the body is provided with a plurality of uniformly-distributed T-shaped heat-radiation fins, a support extending toward two sides is arranged on the bottom of the outer wall of the body, the center of the end covers has an opening, an annular projection is arranged on the periphery of the opening and protrudes out of the end cover, installation positioning holes in a ring are arranged on the periphery of the annular projection, and the inner wall of the body is provided with bar-shaped tooth grooves distributed in a ring. According to the heat-radiation and noise-reducing motor housing, a heat-radiation board is arranged on the motor housing, so that the temperature of a motor in operation is reduced; the outer wall of the body is of the double-layer structure having the middle interlayer, so that an effect of effectively reducing noise is achieved; and the heat-radiation and noise-reducing motor housing is simple to manufacture, high in stability, good in heat radiation, convenient to install, and long in service life.

Description

Heat radiation noise reduction motor housing
Technical field
The utility model relates to technical field of motors, good and the motor housing that can noise reduction of especially a kind of thermal diffusivity.
Background technology
Current most motor case is all manufactured by cast iron, the shortcoming of cast iron is quality weight, heat conductivility is undesirable, and the motor heating that works long hours can affect its performance, makes its job insecurity, existing is all generally that external increase fan dispels the heat to it, this radiating effect is bad, and the quality of aluminium is light, has good heat conductivility, be formed from aluminium the gelled motor case of tool, can allow operating motor dispel the heat better.But because technology is limit, can only cast now the thinner aluminium motor case of fin density of several kilowatts, motor case large with aluminum casting power and that have not only a fin of close but also Bao Youkuan is temporarily difficult to one-body molded, and can produce very large noise during motor High Rotation Speed.
Utility model content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of thermal diffusivity good and can noise reduction motor housing.
The utility model solves the technical scheme that its technical problem adopts: a kind of heat radiation noise reduction motor housing, comprise cylindrical housings, described cylindrical housings one end has end cap, and described housing sidewall is double-decker, centre is provided with the interlayer of hollow, can play effective noise reduction; On described housing periphery wall, be provided with the equally distributed T-shaped fin of complex root, the thermal effect that disappears is good; In order to play effective supporting role, described housing outer wall bottom is provided with the support stretching to both sides, described end cap center is provided with perforate, described perforate is provided with a circle annular protrusion of outstanding end cap around, described annular protrusion is provided with a circle mounting-positioning holes around, in described inner walls, be provided with the bar shaped groove of annular spread, can make motor better be fixed in housing.
Further, described housing and end cap are integral type structure.
Further, described T-shaped fin is connected by soldering with housing outer surface, and described housing and T-shaped fin are aluminum alloy materials and make, and because aluminium alloy has good heat conductivility, can allow operating motor dispel the heat better.
Further, the quantity of described mounting-positioning holes is three.
The beneficial effects of the utility model are, heat radiation noise reduction motor housing of the present utility model is owing to being provided with heating panel on motor housing, temperature while having reduced motor operation, housing outer wall is double-decker, is provided with intermediate course, can play the effect that effectively reduces noise, make simple, stability is high, thermal diffusivity good, convenient installation, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is end view of the present utility model.
Fig. 2 is the structural representation of the utility model opposite side.
1. housings in figure, 2. end cap, 3. interlayer, 4.T type fin, 5. support, 6. perforate, 7. annular protrusion, 8. mounting-positioning holes, 9. bar shaped groove.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
Heat radiation noise reduction motor housing as shown in Fig. 1 Fig. 2, comprise cylindrical housings 1, cylindrical housings 1 one end has and the integrated end cap 2 of housing 1, the noise producing when reducing motor High Rotation Speed, housing 1 sidewall is set to double-decker, centre is provided with the interlayer 3 of hollow, can effectively reduce noise.For better heat radiation, on housing 1 periphery wall, be provided with the equally distributed T-shaped fin 4 of complex root.Housing 1 outer wall bottom is provided with the support 5 stretching to both sides, plays effective supporting role.End cap 2 centers are provided with perforate 6, and perforate 6 is provided with a circle annular protrusion 7 of outstanding end cap around, and annular protrusion 7 is provided with a circle mounting-positioning holes 8 around, and wherein, the quantity of mounting-positioning holes 8 is three.On housing 1 inwall, be provided with the bar shaped groove 9 of annular spread, can make motor better be fixed in housing 1, while avoiding moving, skid off.T-shaped fin 4 is connected by soldering with housing 1 outer surface, and housing 1 and T-shaped fin 4 are aluminum alloy materials and make, and because aluminium alloy has good heat conductivility, can allow operating motor dispel the heat better, has promoted further radiating effect.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
