Abstract
The utility model discloses a motor end cap which comprises a body. The body is provided with a mounting sheet on which mounting holes are arranged. The central position of the body is provided with an annular chamber in which a sealing ring is arranged. Heat radiating holes are distributed on the circumference of the annular chamber with equal angles. Fixing holes are arranged at the circumference of the annular chamber. The periphery of the annular chamber is connected with the edge of the body through ribs. The edge of the body is provided with counterweights. The motor end cap can effectively prevent entering of dust and steam in the air into the inner part of the motor through arranging the sealing ring in the annular chamber. Through arranging the heat radiating holes and the ribs, the following functions can be performed: reducing weight, reducing cost, enlarging heat radiation area, quickly radiating the heat to outside of the motor, and prolonging service life of the motor. The arrangement of the counterweights prevents gravity center offset of the end cap body caused by non-uniform mass and ensures concentricity between the end cap and an output shaft.
Description
The utility model relates to technical field of motors, especially a kind of electric motor end cap.
Background technology
Existing electric motor end cap is mostly dull and stereotyped disc type, unitary solid consume material, mechanical strength is not high, and the annular chamber at middle part does not pass through encapsulation process, easily make airborne dust and steam enter motor, end cap entire area is poor compared with brief biography thermal effect, and the bad meeting of dispelling the heat causes motor temperature fast rise, affects the useful life of motor, on electric motor end cap, have installing hole, make the quality of end cap inhomogeneous, make end cap centre-of gravity shift, affect the concentricity of end cap and output shaft.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of good heat dissipation is provided, lightweight, cost is low, with the electric motor end cap of sealing ring and balancing weight.
For achieving the above object, the technical solution of the utility model is: a kind of electric motor end cap, comprise body, described body is provided with installation sheet, and described installation sheet is provided with installing hole, described body center position is provided with annular chamber, in described annular chamber, be provided with sealing ring, annular chamber circumference spaced at equal angles around has louvre, and the surrounding of annular chamber has fixing hole, between annular chamber periphery and body edges, by rib, connect, described body edges is provided with balancing weight.
The material of described sealing ring is rubber.
Described rib is structure as a whole.
The beneficial effects of the utility model are: by establish sealing ring in annular chamber, can effectively prevent that airborne dust and steam from entering motor internal; By louvre and rib are set, alleviated weight, reduced cost, increased area of dissipation, make heat to be dispersed into rapidly outside motor, extended electrical machinery life; The setting of balancing weight has been avoided because quality is inhomogeneous, causing end cap body centre-of gravity shift, has guaranteed the concentricity of end cap and output shaft.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: body 1, installation sheet 2, installing hole 3, annular chamber 4, sealing ring 5, louvre 6, fixing hole 7, rib 8, balancing weight 9.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of electric motor end cap, comprise body 1, described body 1 is provided with installation sheet 2, and described installation sheet 2 is provided with installing hole 3, described body 1 center position is provided with annular chamber 4, in described annular chamber 4, be provided with sealing ring 5, annular chamber 4 circumference spaced at equal angles around have louvre 6, and the surrounding of annular chamber 4 has fixing hole 7, between annular chamber 4 peripheries and body 1 edge, by rib 8, connect, described body 1 edge is provided with balancing weight 9.
The material of described sealing ring 5 is rubber.
Described rib 8 is structure as a whole.
The utility model, by establish sealing ring 5 in annular chamber 4, can effectively prevent that airborne dust and steam from entering motor internal; By louvre 6 and rib 8 are set, in the situation that guaranteeing original mechanical strength, alleviated weight, reduced cost, increased area of dissipation, make heat to be dispersed into rapidly outside motor, extended electrical machinery life; The setting of balancing weight 9 has been avoided because quality is inhomogeneous, causing body 1 centre-of gravity shift, has guaranteed the concentricity of end cap and output shaft.
