DETAILED DESCRIPTION

[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0014] like Figure 1 As shown, the servo motor with dustproof effect includes a motor housing 100 and a motor end cover 200. The front end of the motor housing 100 is provided with a flange end face 110 integrally formed therewith, and the rear end of the motor housing 100 is provided with a sealing gasket 130 corresponding to the shape of the motor body at the connection with the motor end cover 200. The sealing gasket 130 protrudes from the outer surfaces of the motor housing 100 and the motor end cover 200 and wraps the connection between the two, thereby ensuring the sealing of the connection between the motor housing 100 and the motor end cover 200, and preventing external dust from invading the interior of the servo motor after long-term use.

[0015] The tops of the motor housing 100 and the motor end cover 200 are fixed with dustproof parts 300 by fixing bolts 310, which are used to protect the interfaces to prevent dust from falling and affecting the operation of the motor. The dustproof parts 300 are located on both sides of the sealing gasket 130, and the interior is a cavity structure and is connected to the interface of the servo motor. The openings of the dustproof parts 300 are located on both sides to prevent dust from falling on the openings.

[0016] When the servo motor is working, the dustproof piece 300 on the motor housing 100 is connected to the power supply pipe 321, the dustproof piece 300 on the motor end cover 200 is connected to the feedback pipe 322, and the wiring inside the power supply pipe 321 and the feedback pipe 322 is connected to the connector inside the dustproof piece 300; when the servo motor is not working, a dustproof cover 323 is installed at the opening of the dustproof piece 300.

[0017] Further explanation, the flange end face 110 is provided with structural ribs 111 around the motor shaft at the center, which are used to strengthen the structural strength of the flange end face 110. A plurality of material reduction grooves 112 are provided between the structural ribs 111. The material reduction grooves 112 can save materials while ensuring the structural strength, thereby reducing production costs. The motor housing 100 is provided with a plurality of heat dissipation grooves 120 on the outer surface of the body behind the flange end face 110, and the heat dissipation grooves 120 strengthen the internal heat dissipation of the servo motor.
