Abstract
The utility model relates to an end cover of a motor, which comprises an end cover body, a bearing component and a connecting flange. The end cover of the motor is characterized in that the bearing component and the connecting flange are arranged on the end cover body, are divided into two parts and are connected into a whole; and a ventilating duct is arranged on the end cover body. The end cover of the motor has advantages that the structure is simple, compact and reasonable; the heat dissipation effect and the ventilation effect of the motor are good, the temperature of the bearing component in a 250 motor is significantly reduced by 7-8 DEG C, the service life of the bearing component is greatly improved, and the reliability of the motor is improved; and the material of the motor is saved, the cost is lowered, and the weight of the end cover of the motor can be saved by 1-2 kg.
Description
Technical field
The utility model relates to a kind of electric motor end cap, specifically a kind of constitutional detail that is used to connect motor internal rotor and support.
Background technology
Along with science and technology development and progress, people more and more pay attention to energy-conservation and low-carbon (LC) has been lived.The end cap of motor shields to motor internal on the one hand, on the other hand by being installed in the relative position that bearing in the end cap guarantees stator and rotor.
In prior art, existing end cap is relatively heavier, and radiating effect is not good enough, the motor ventilation weak effect, and the bearing temperature rise height has the just inapplicable of strict control for ask for something motor bearings temperature.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of electric motor end cap is provided, and the bearing heat radiation in this end cap can improve greatly, and its ventilation effect is remarkable, and electric machine temperature rise obviously reduces, and has saved and used material.
The technical scheme that provides according to the utility model, a kind of electric motor end cap comprises end cover body, bearing assembly, adpting flange, feature is: described end cover body is provided with bearing assembly and adpting flange, bearing assembly and adpting flange are divided into two parts, and described bearing assembly is connected in one by reinforcement and adpting flange.
Described end cover body is provided with air duct.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Radiating effect, motor ventilation are effective, and the bearing assembly temperature obviously descends, and 250 motor bearings assembly temperatures, 7～8 degree that descended in the useful life of having improved bearing assembly greatly, have improved the reliability of motor; Saved the material of using of motor, reached the purpose that reduces cost, one 250 electric motor end cap can be saved 1～2Kg.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise end cover body 1, bearing assembly 2, adpting flange 3, described end cover body 1 is provided with bearing assembly 2 and adpting flange 3, and bearing 2 and adpting flange 3 are divided into two parts, and described bearing assembly 2 is connected in one by reinforcement 4 and adpting flange 3.Described end cover body 1 is provided with air duct 5.The utility model does not change the assembly mode of original motor.
Claims (2)
