Problems solved by technology
[0003] Due to the design defects of the shell in the prior art, the heat dissipation effect of the motor is often poor. With the prolongation of the use time, the heat accumulates faster and the heat dissipation is slower, which greatly shortens the service life of the motor; at the same time, the existing The DC motor shell is generally one-piece structure, which is only suitable for the installation of a rotor of one size and type, and the practicability is poor; and because the heat dissipation holes are directly exposed, there is no dust-proof mechanism, which will easily cause dust and impurities inside the motor to accumulate, seriously Affect the efficiency of the motor

Embodiment Construction
[0063] Such as Figure 1 to Figure 9 As shown, it is a DC motor housing of the present invention, which includes a front end cover 1, a rear end cover 2 and a splicing unit 3. The front end cover 1 is provided with a first shaft sleeve 6 and a cooling hole, and the first shaft sleeve 6 is located at the front end. At the center of the cover 1, the cooling holes are arranged symmetrically on both sides of the first bushing 6, the first bushing 6 is used to support the motor shaft and improve the stability of the rotor, the cooling holes can dissipate the heat inside the motor housing Dissipate it, reduce the temperature inside the motor, and prolong the service life of electronic components.
[0064] The rear end cover 2 is provided with a second shaft sleeve 11 and a frame body 12, the second shaft sleeve 11 is located at the center of the rear end cover 2, the frame body 12 is arranged on both sides of the second shaft sleeve 11, and the frame body 12 is provided with There ...

The invention discloses a direct-current motor shell and a manufacturing method thereof. The motor shell comprises a front end cover, a rear end cover and a splicing single body, wherein the splicingsingle body is fixedly connected between the front end cover and the rear end cover through a positioning rod, conical rings are arranged in the splicing single body, the front end cover and the rearend cover, the conical rings are obliquely arranged in one direction, a heat dissipation channel is formed between every two adjacent conical rings, a positioning mechanism is arranged in each heat dissipation channel, and a dustproof mechanism is arranged on the outer side of each heat dissipation channel. The method comprises the steps of processing the front end cover, processing the rear end cover, processing the splicing single body, processing the dustproof mechanism and splicing the motor shell. The mounting requirements of direct-current motor shells of different sizes can be met, useis flexible and convenient, mounting and dismounting are convenient and rapid, the heat dissipation effect is improved, the dustproof mechanisms on all the heat dissipation channels can conduct filtering treatment, dust and impurities entering the motor are reduced, and the service life of the motor is prolonged.
Description
technical field [0001] The invention relates to a DC motor casing and a manufacturing method thereof. Background technique [0002] A DC motor is an electric motor that converts DC electrical energy into mechanical energy. It is widely used in electric drive because of its good speed regulation performance. [0003] Due to the design defect of the shell in the prior art, the heat dissipation effect of the motor is often poor. With the prolongation of the use time, the heat accumulates faster and the heat dissipation is slower, which greatly shortens the service life of the motor; at the same time, the existing The DC motor shell is generally one-piece structure, which is only suitable for the installation of a rotor of one size and type, and the practicability is poor; and because the heat dissipation holes are directly exposed, there is no dust-proof mechanism, it is easy to cause dust and impurities inside the motor to accumulate, seriously affect the efficiency of the m...
