Abstract
The utility model discloses an end cover of a gear motor. A motor shaft extends out of one end of a motor body, a shaft hole is arranged in the center of a motor end cover body, the outer ring of the motor shaft matches the shaft hole of the motor end cover body, the motor end cover body is provided with wind-guiding edges which are uniformly distributed by taking the shaft hole as the center, and the end portion of the motor shaft is provided with a fan blade which is in interference fit with the motor shaft via knurling. According to the utility model, the motor end cover is provided with the wind-guiding edges, so that the heat radiation performance of the motor is improved and the operation time and service life of the motor are prolonged without increase of cost, and the end cover is simple and reliable in structure and convenient to assemble.
Description
Technical field
The utility model relates to design of electrical motor manufacturing technology field, is specifically related to a kind of reducing motor end cap.
Background technology
Motor is a kind of calutron of realizing conversion or the transmission of electric energy according to the law of electromagnetic induction.Motor is commonly called as motor, and its Main Function is to produce driving torque, thereby as the power source of electrical equipment or various machineries.Reducing motor is the conglomerate of reductor and motor.
At present, reducing motor is widely used in the various occasions such as various office equipment, plant equipment and household electrical appliance.The features such as the motor that household electrical appliance require to use has longevity of service, noise is little, the life-span is long and cost is low, and existing household kitchen oil press uses reducing motor due to its ceaselessly running for a long time, Inside coil has produced a large amount of heats, and these heats can not distribute in time, and cause burning out motor, and affect the use of household electrical appliance.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of good heat dissipation effect, can extend the motor reducing motor end cap in useful life.
The technical solution adopted in the utility model is such:
A kind of reducing motor end cap, comprises motor body 1 and motor side lid 2, and motor shaft 3 is stretched out in one end of motor body 1, and the center of described motor side lid 2 is provided with axis hole 4, matches with the axis hole 4 of described motor side lid 2 in described motor shaft 3 outer rings; Described motor side lid 2 is provided with wind-guiding edge 6, and described wind-guiding edge 6 is uniformly distributed centered by axis hole 4; The end of described motor shaft 3 is also provided with a fan blade 7, adopts annular knurl interference to be connected with motor shaft 3.
As preferably, the central axes of the central axis of described motor shaft 3 and motor side lid 2.
As preferably, on described motor side lid 2, be also provided with the fixing threaded hole 5 being connected with motor.
As preferably, described wind-guiding edge 6 adopts die casting one-shot forming, and fan blade 7 adopts injection moulding one-shot forming.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
The utility model, by be provided with wind-guiding edge on electric motor end cap, in the situation that increasing cost hardly, has improved the heat dispersion of motor, has extended running time and the useful life of motor, simple and reliable for structure, easy to assembly.
