[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figure 1-6 As shown, the utility model provides a water-cooled servo speed reduction melt-melting motor, comprising:

[0033] The servo motor 100 includes a motor housing 110 and a driving mechanism disposed in the motor housing 110;

[0034] A reducer 200 is assembled with the motor housing 110 and is in transmission connection with the driving mechanism. The speed of the driving mechanism is reduced and its torque is amplified by the reducer 200;

[0035] A water inlet 111 and a water outlet 112 are provided on the motor housing 110. A plurality of water cooling channels 113 are provided inside the motor housing 110. At the same time, confluence channels are provided at both ends of the motor housing 110. The water inlet 111 and the water outlet 112 are respectively connected to the water cooling channels 113. The water cooling channels 113 are connected to each other through the confluence channel. The cooling water flowing in from the water inlet 111 enters a water cooling channel 113, then flows through the confluence channel through each water cooling channel 113, and then flows out from the water outlet 112.

[0036] Thus, the entire servo reduction melt-melting motor forms a water-cooled structure, and the temperature inside the motor housing 110 is reduced through the continuous circulation of cooling water, ensuring that the inside of the motor housing 110 will not overheat even after long-term operation, thereby extending its service life.

[0037] Preferably, a plurality of water cooling channels 113 are arranged at intervals along the circumference of the motor housing 110, and each water cooling channel 113 extends along the axial direction of the motor housing 110. Thus, as the cooling water flows through each water cooling channel 113, the entire motor housing 110 can be evenly cooled, thereby improving the cooling effect inside the motor housing 110.

[0038] Preferably, the confluence channel includes a plurality of first confluence channels 114, wherein adjacent water-cooling channels 113 are connected via the first confluence channel 114, and two adjacent first confluence channels 114 are separated, thereby, each individual water-cooling channel 113 can be divided into multiple groups, and each water-cooling channel 113 in a group of water-cooling channels 113 is connected via the first confluence channel 114.

[0039] Preferably, the confluence channel further includes a second confluence channel 115 , the second confluence channel is located at both ends of the water cooling channel 113 , and the first confluence channel 114 is located between the second confluence channel and the water cooling channel 113 .

[0040] Specifically, each first confluence channel 114 is interconnected through a total second confluence channel, that is, when the cooling water enters a water cooling channel 113 from the water inlet 111, the cooling water will be distributed to each first confluence channel 114 through the second confluence channel, and then distributed to a single water cooling channel 113 through each first confluence channel 114, thereby ensuring that the cooling water can smoothly flow into any water cooling channel 113, thereby ensuring that the motor housing 110 can be evenly cooled.

[0041] Preferably, a drive shaft 120, a rotor 130 and a stator coil 140 are installed in the motor housing 110, wherein the head end of the drive shaft 120 extends outward from the motor housing 110, the rotor 130 is sleeved on the drive shaft 120 and the two are cooperatively connected, and the stator coil 140 is sleeved on the rotor 130 and the two are cooperatively connected. After power is turned on, a magnetic field is generated by the stator coil 140, driving the rotor 130 to rotate, realizing the conversion of electrical energy into mechanical energy, and finally driving the drive shaft 120 to rotate.

[0042] Preferably, bearings 150 are installed at the front and rear ends of the drive shaft 120 located in the motor housing 110 , and the drive shaft 120 is supported by the bearings 150 and the friction force during the rotation of the drive shaft 120 is reduced.

[0043] Preferably, the reducer 200 is configured as a planetary gearbox, and the housing of the planetary gearbox is connected to the motor housing.

For example, in this embodiment, there are two groups of sun gears 210 and planetary gears 220 to form a two-stage planetary reduction mechanism;

[0046] The output shaft 230 is drivingly connected to the drive shaft 120 via a planetary reduction mechanism formed by the sun gear 210 and the planetary gears 220 .
