Abstract

The utility model discloses a motor end cover, which comprises an end cover body, the back of which is provided with a plurality of ribs in radial distribution. By employing the above structure, the motor end cover has the advantages that the motor end cover employs the structure of laces at a front side and a plurality of ribs at a reverse side, so that heat radiation area at the outer surface of the motor end cover is increased, inner heat absorption area is increased, thus heat in a motor can be conducted to the outer surface of a motor base rapidly so as to facilitate heat radiation, reduce motor temperature rise, and improve motor performance; and with original mechanical strength being guaranteed, the motor end cover reduces wall thickness, lightens weight, and achieves the purpose of material saving, and the reasonable structure of the motor end cover reduces the vibration and noise of the motor.

Description

A kind of electric motor end cap

Technical field

The utility model relates to technical field of motors, particularly a kind of electric motor end cap.

Background technology

At present, the conventional motors great majority are dull and stereotyped disc type end cover structure, and there are some problems in this structure, as the unitary solid consume material; Mechanical strength not high (internal structure is loose during unitary solid material die casting aluminium); The less heat-transfer effect of area is poor; With extraneous junction without insert, there is potential safety hazard.

The utility model content

Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide the electric motor end cap of a kind of good heat dissipation effect, weight reduction.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of electric motor end cap, comprise the end cap body, and the back side of described end cap body is provided with many radially-arranged ribs.

Described many ribs are structure as a whole.

The front periphery of described end cap body is provided with a plurality of grooves, forms the lace structure.

The middle part of described end cap body is provided with the bearing inserts.

The utility model adopts said structure, have the following advantages: 1, adopt positive lace type, the structure of many ribs of reverse side, the area of dissipation of electric motor end cap outer surface is increased, inner endotherm area increases, and the heat of motor internal can be conducted to the support outer surface rapidly like this, helps heat radiation, and the temperature rise of reduction motor, improve motor performance; 2, guarantee to have reduced wall thickness under the situation of original mechanical strength, alleviated weight, reach the purpose of material-saving, also reduced the vibration and the noise of motor simultaneously because of its rational structure.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;

Fig. 1 is the structure schematic diagram of end cap body in the utility model;

Fig. 2 is the Facad structure schematic diagram of end cap body in the utility model;

In Fig. 1～Fig. 2,1, the end cap body; 2, rib; 3, bearing inserts.

Embodiment

As Fig. 1～a kind of electric motor end cap shown in Figure 2, comprise end cap body 1, the back side of end cap body 1 is provided with many radially-arranged ribs 2.Many ribs 2 are structure as a whole.The front periphery of end cap body 1 is provided with a plurality of grooves, forms the lace structure.The middle part of end cap body 1 is provided with bearing inserts 3, also is provided with inserts and seal groove structure, and seal groove can improve the motor degree of protection.End cap body 1 adopts the die casting aluminium structure, can improve mechanical strength.

End cap body 1 adopts positive lace type, the structure of many ribs of reverse side, the area of dissipation of electric motor end cap outer surface is increased, inner endotherm area increases, the heat of motor internal can be conducted to the support outer surface rapidly like this, help heat radiation, and reduce the temperature rise of motor, improve motor performance; Guarantee to have reduced wall thickness under the situation of original mechanical strength, alleviated weight, reach the purpose of material-saving, also reduced the vibration and the noise of motor simultaneously because of its rational structure.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection range of the present utility model.
