Description
Technical field
The utility model belongs to technical field of motors, is specifically related to a kind of end cover for motor.
Background technology
Motor is the electronic product in industrial production and daily life, motor is by stator, rotor, the large parts composition of end cap three, the effect of end cap in motor is shield to internal structure of motor on the one hand, prevent the infringement that external force causes motor, also can be dust-proof, moistureproof, the relative position of stators and rotators is ensured on the other hand by the bearing be arranged in end cap, electric motor end cap is mostly flat-disc formula, unitary solid shape, the electric motor end cap of this kind of structure compares consume material, mechanical strength is poor, and, the annular chamber at middle part is usually without encapsulation process, the dust in air and steam is easily made to enter into motor, unitary solid shape, usually heavier, radiating effect is poor, easily causes motor temperature to rise fast, has the strict place controlled just can not be suitable for, have influence on the useful life of motor simultaneously for ask for something motor bearings temperature.
Utility model content
For problems of the prior art, it is simple that the utility model object is to provide a kind of structure, lower-cost end cover for motor.
The utility model is realized by the following technical programs:
Described a kind of end cover for motor, comprise end cap body, one-body moldedly on described end cap body be provided with brace, the position of the corresponding brace of described end cap is provided with installing hole, it is characterized in that the center position of described end cap is provided with annular chamber, the center position of described annular chamber is provided with bearing chamber, and the bottom of described bearing chamber is provided with sealing ring, is connected between the inwall of described annular chamber and the outer wall of bearing chamber by reinforcement.Form louvre between adjacent reinforcement, conveniently timely the heat in motor is distributed.
Described a kind of end cover for motor, is characterized in that one-body moldedly on described end cap being provided with the first ventilation holes.This first ventilation holes is rectangle shape, the interchange of convenient inside and outside gas.
Described a kind of end cover for motor, is characterized in that the uniform outer edge being arranged on the corresponding annular chamber of end cap of the first ventilation holes.
Described a kind of end cover for motor, is characterized in that described first ventilation holes is provided with four.
Described a kind of end cover for motor, the circle wall that it is characterized in that described end cap is provided with the second ventilation holes and the 3rd ventilation holes.
Described a kind of end cover for motor, is characterized in that described 3rd ventilation air vent hole is arranged on the position of the corresponding brace of corresponding end cap circle wall.
Described a kind of end cover for motor, it is characterized in that being provided with dustproof sheet in described second ventilation holes and the 3rd ventilation holes, described dustproof sheet is network structure.
Described a kind of end cover for motor, is characterized in that the aperture of described 3rd ventilation holes is greater than the aperture of the second ventilation holes.
The utility model structure is simple, reasonable in design, by arranging sealing ring in bearing chamber, can effectively avoid the dust in air and steam to enter into motor; The ventilation holes arranged, makes the heat dispersion of motor better, the setting of reinforcement and ventilation holes, effectively can improve structural strength, saves cost, reduces end cap overall weight, reduces vibration, corresponding useful life of improving end cap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-end cap body, 2-brace, 3-installing hole, 4-annular chamber, 5-bearing chamber, 6-sealing ring, 7-reinforcement, 8-first ventilation holes, 9-second ventilation holes, 10-the 3rd ventilation holes, 11-dustproof sheet.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, and provides embodiment.
As shown in Figure 1, a kind of end cover for motor of the utility model, comprise end cap body 1, one-body moldedly on this end cap body be provided with brace 2, the position of the corresponding brace of end cap body is provided with installing hole 3, and this installing hole is spirally connected by screw and motor housing and arranges, the center position of end cap is provided with annular chamber 4, the center position of this annular chamber is provided with bearing chamber 5, and the bottom of bearing chamber 5 is provided with sealing ring 6, is connected between the inwall of annular chamber and the outer wall of bearing chamber by reinforcement 7.Form through hole between adjacent reinforcement, this through hole can be louvre, is distributed in time by the heat that motor produces; For making radiating effect better, convenient inside and outside air-flow exchanges, one-body moldedly on end cap be provided with the first ventilation holes 8, second ventilation holes 9, the 3rd ventilation holes 10, first ventilation holes 8 is provided with four, be specially the uniform outer edge being arranged on the corresponding annular chamber of end cap; Second ventilation holes 9 and the 3rd ventilation holes 10 are arranged in the circle wall of end cap, wherein, 3rd ventilation holes 10 is arranged on the position of the corresponding brace of end cap circle wall, and the aperture of the 3rd ventilation holes 10 is greater than the aperture of the second ventilation holes 9, enter in motor for better stoping the dust etc. in air, in the second ventilation holes 9 and the 3rd ventilation holes 10, be provided with dustproof sheet 11, this dustproof sheet is network structure.
The utility model by arranging sealing ring bottom bearing chamber, can effectively prevent the dust in air and steam from entering motor internal, by reinforcement and the ventilation holes of setting, when ensureing original mechanical strength, alleviating weight, reducing cost, add area of dissipation simultaneously, promote the interchange of inside and outside gas, make heat can be dispersed into outside motor rapidly, extend the useful life of motor.
