[0017] See also Figure 1-3 This embodiment provides a technical solution: a micro right-angle transmission reduction motor, including a motor body 1, a heat dissipation hood 2 is provided at the lower end of the motor body 1, a limiting protrusion 9 is provided on the inner side of the heat dissipation hood 2, a screw seat 8 is provided on the outer ring side of the limiting protrusion 9, a support frame 6 is provided at the center of the inner side of the heat dissipation hood 2, a shaft sleeve 5 is provided at the center of the support frame 6, a blade 7 is provided at one end of the shaft sleeve 5, and a ventilation slot 12 is provided in one end of the heat dissipation hood 2.

[0018] like Figure 1-3 As shown, the heat dissipation hood 2 is mounted on the lower end of the motor body 1 through the limiting protrusion 9, and the heat dissipation hood 2 is connected and fixed to the motor body 1 with screws. The lower end of the rotating shaft of the motor body 1 is keyed to the shaft sleeve 5. When the motor body 1 rotates, it can drive the blades 7 to rotate, thereby cooling the motor body 1 with air to ensure the working performance of the motor body 1.

[0019] An eccentric bevel gear reducer 4 is provided at the upper end of the motor body 1 , and a semiconductor refrigeration plate 10 is provided on the upper side of the eccentric bevel gear reducer 4 .

[0020] like Figure 1 As described above, the semiconductor refrigeration plate 10 can cool down and then cool down the eccentric bevel gear reducer 4 to ensure stable operation of the eccentric bevel gear reducer 4. The heat dissipation ribs 11 can dissipate heat to ensure that the semiconductor refrigeration plate 10 is effectively cooled.

[0021] A heat dissipation rib 11 is provided on the upper side of the semiconductor refrigeration plate 10 , and an output shaft 3 is provided on one side of the eccentric bevel gear reducer 4 .

[0022] The motor body 1 is fixedly connected to the eccentric bevel gear reducer 4 , and the semiconductor refrigeration plate 10 is glued to the eccentric bevel gear reducer 4 .

[0023] A keyway is provided on the output shaft 3 , and the heat dissipation hood 2 is fixedly connected to the motor body 1 .

[0024] like Figure 1 As shown, the output shaft 3 can drive the rotating structure to rotate.

[0025] The lower end of the rotating shaft of the motor body 1 is key-connected to the shaft sleeve 5, and the shaft sleeve 5 is connected to the support frame 6 through a bearing.

[0026] The support frame 6 and the limiting protrusion 9 are an integrated structure, and the limiting protrusion 9 can limit and fix the lower end of the motor body 1.

[0027] When the motor body 1 is running, the output end is decelerated by the eccentric bevel gear reducer 4. The decelerated output shaft 3 can drive the rotating structure to rotate. When the motor body 1 rotates, the rotating shaft is connected to the shaft sleeve 5, which can drive the blades 7 to rotate rapidly, thereby performing air cooling and heat dissipation treatment on the motor body 1. There is a gap between the heat dissipation hood 2 and the motor body 1, thereby ensuring that air can quickly flow into the heat dissipation hood 2 from the outside of the motor body 1 and be blown out through the ventilation slots 12, so that the motor body 1 can be effectively cooled.
