In addition, the shaded pole motor is used to drive the transmission mechanism 2, the structure of the shaded pole motor is relatively simple, easy to manufacture, convenient to maintain, reliable in operation and low in noise; the shaded pole motor has self-starting capability and small starting torque, and is suitable for light load starting equipment, such as used in ice machines.

[0036] As Figure 2 and 3As shown, in this embodiment, the output shaft of the drive motor 12 is connected to a worm gear 11. Specifically, the output shaft of the drive motor 12 and the worm gear 11 are integrally formed, that is, a helical worm gear is machined at the end of the output shaft of the drive motor 12.

[0037] The primary transmission assembly 21 includes a worm gear 211 and a first gear 212. The worm 11 meshes with the worm gear 211. The teeth on the worm gear 211 are helical, and the teeth on the first gear 212 are spurs. The first gear 212 is coaxially arranged and fixedly connected to the worm gear 211. The module of the first gear 212 is smaller than that of the worm gear 211, that is, the first gear 212 is a small-diameter gear, and the worm gear 211 is a large-diameter gear, in preparation for the deceleration of the transmission mechanism 2. The first gear 212 is connected to the secondary transmission assembly 22. In this structure, the output shaft of the power mechanism 1 drives the worm gear 211 to rotate through the worm 11. The first gear 212 is coaxially arranged and fixedly connected to the worm gear 211. The axis of the worm 11 is parallel to the rotation axis of the worm gear 211, so that the power mechanism 1 drives the worm 11 to rotate, the worm 11 drives the first gear 212 to rotate synchronously, and the first gear 212 drives the secondary transmission assembly 22. As one embodiment, the output shaft of the power mechanism 1 is connected to the worm gear 11 via a coupling, or the output shaft of the power mechanism 1 is directly integrally formed with the worm gear 11.

[0038] The rotating shafts of the first gear 212 and the worm gear 211 rotate together with the first gear 212 and the worm gear 211. The two ends of the rotating shafts of the first gear 212 and the worm gear 211 are respectively rotatably installed in the limiting grooves on the inner wall of the housing. The limiting grooves limit the rotating shafts of the first gear 212 and the worm gear 211 to prevent the worm gear 211 from disengaging from the worm 11 and to prevent the first gear 212 from failing to transmit power to the secondary transmission assembly 22.

[0039] like Figures 2-4 As shown, in this embodiment, the secondary transmission component 22 includes a second gear 221 and a third gear 222, both of which have spur teeth. The second gear 221 meshes with the first gear 212, and the module of the second gear 221 is greater than that of the first gear 212, thus achieving the first reduction transmission of the transmission mechanism 2. Furthermore, the first gear 212 and the second gear 221 are parallel gears, resulting in smoother transmission and higher transmission efficiency. Parallel gears refer to a gear transmission form where the shafts of the first gear 212 and the second gear 221 are parallel and coplanar. Using parallel gears, the meshing between the gears mainly relies on rolling contact, resulting in lower friction and higher efficiency.

The third gear 222 is in transmission connection with the third-stage transmission assembly 23. In this structure, the rotating shafts of the worm gear 211 and the first gear 212, the rotating shafts of the second gear 221 and the third gear 222 are arranged in parallel and parallel to each other, realizing that the rotating first gear 212 drives the second gear 221 to rotate, and the third gear 222 drives the third-stage transmission assembly 23 to rotate.

[0041] The rotating shafts of the second gear 221 and the third gear 222 rotate with the second gear 221 and the third gear 222, and the two ends of the rotating shafts of the second gear 221 and the third gear 222 are respectively rotatably installed in the limiting grooves on the inner wall of the shell. The limiting grooves limit the rotating shafts of the first gear 212 and the worm gear 211, avoiding the disengagement of the second gear 221 and the first gear 212, and avoiding the transmission failure of the third gear 222 and the third-stage transmission assembly 23.

[0042] As shown in Figures 2-4 In this embodiment, the third-stage transmission assembly 23 includes a fourth gear 231, the fourth gear 231 is in engagement with the third gear 222, and the teeth of the fourth gear 231 are straight teeth; the modulus of the fourth gear 231 is greater than the modulus of the third gear 222, realizing the second reduction transmission of the transmission mechanism 2.

[0043] The fourth gear 231 and the third gear 222 are parallel gears, and the transmission mode of the parallel gears is adopted. The engagement between the gears mainly relies on rolling contact, and the friction is small, so that the transmission is more stable, and the transmission efficiency is higher.

[0044] The fourth gear 231 is provided with the power output part 232. In this structure, the rotating shafts of the second gear 221 and the third gear 222 and the rotating shaft of the fourth gear 231 are arranged in parallel and parallel to each other, realizing that the rotating third gear 222 drives the fourth gear 231 to rotate, the fourth gear 231 is provided with the power output part 232, the mounting part of the ice skate can be mounted on the power output part 232, and then the rotation of the ice skate is driven, and the ice block is broken into crushed ice.

[0045] The axis of the worm 11, the rotation axes of the worm wheel 211 and the first gear 212, the rotation axes of the second gear 221 and the third gear 222, and the rotation axis of the fourth gear 231 are arranged in parallel and parallel to each other, that is, the worm 11, the worm wheel 211 and the first gear 212, the second gear 221 and the third gear 222, and the fourth gear 231 are arranged side by side, integrated in the shell 3, forming a flat structure, so that the height of the transmission mechanism is reduced, the structure is compact, the reliability and stability of the transmission structure are greatly improved, and the transmission efficiency is high. It can transmit a larger power and speed range.

[0046] As an embodiment, the first gear 212, the second gear 221, the third gear 222 and the fourth gear 231 are spur gears, which have large transmission ratio, small noise, light vibration and long service life. In some embodiments, the first gear 212, the second gear 221, the third gear 222 and the fourth gear 231 can also be helical gears, which are not easy to disengage.

[0047] As shown in Figure 2 In this structure, the driving motor 12 drives the worm 11 to rotate, and the heat dissipation member 13 can dissipate heat from the driving motor 12. The heat dissipation member 13 can be a fan or a heat dissipation fin.

[0048] As an embodiment, the driving motor 12 is a shaded pole motor, which is a mature and existing motor. It has the characteristics of simple structure, easy manufacturing, convenient maintenance, reliable operation and low noise. In addition, the shaded pole motor has self-starting capability and small starting torque, which is suitable for light load starting equipment such as ice makers. The principle of self-starting capability of the shaded pole motor is that the stator of the shaded pole motor usually has salient pole type magnetic poles, part of each magnetic pole is covered by a short circuit ring. When energized, the currents in the main winding and the short circuit ring will have a phase difference. Because the current in the short circuit ring lags behind the current in the main winding, the two magnetic fields will have a phase difference, thereby forming a rotating magnetic field to start the rotor.

[0049] As shown in Figure 4 In this structure, the worm 11 is inserted into the shell and engaged with the worm wheel 211 to drive the worm 11 and the worm wheel 211.

In this structure, the fourth gear 231 is rotatably connected with the shell 3, and the ice skate is installed through the power output part 232 to realize the driving of the ice skate rotation.

[0051] As shown in the drawings, Figure 1 The shielded pole motor is directly fixedly installed outside the shell 3, and effective transmission of the worm 11 and the worm wheel 211 is ensured.
