[0024] Embodiment 1:

[0025] See also Figure 1 to Figure 5 The utility model discloses a multi-stage variable speed precision planetary reducer, comprising a main body 1, and a transmission shaft 2 is rotatably mounted at the front end of the main body 1.

[0026] An auxiliary device 3 is provided on the right side of the main body 1, and a lubricating device 4 is provided on the top rear end of the main body 1. The auxiliary device 3 includes a transmission shaft 2 plugged and connected with the center of the rear end of the sun gear 31. The rotating transmission shaft 2 drives the sun gear 31 and the bevel gear set 35 to rotate. The tooth groove at the right end of the outer side of the sun gear 31 is meshed and connected with the planetary gear 32. The planetary gear 32 is meshed and connected with the tooth groove on the inner side of the inner gear ring 33. The planetary gear 32 rotates and displaces on the inner gear ring 33.

[0027] A partition 34 is provided at the front right side of the main body 1, and a bevel gear set 35 is rotatably installed on the top of the partition 34. An electromagnetic clutch and an end shaft body are provided at the front end of the transmission shaft 2, and the shaft body is plugged and fixed to the center of the bevel gear at the rear end of the bevel gear set 35. The center of the bevel gear at the bottom end of the bevel gear set 35 is connected to the top bolt of the fan blade 36 through a connecting rod. The rotating bevel gear set 35 drives the fan blade 36 to rotate through the connecting rod, and a dustproof net 37 is fixed to the front end slot on the top of the main body 1 by screws.

[0028] The working principle of a multi-stage variable speed precision planetary reducer based on Example 1 is:

[0029] First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation;

[0030] Second, when performing multi-speed shifting, the rotating transmission shaft 2 drives the sun gear 31 and the bevel gear set 35 to rotate, and the sun gear 31 drives the planetary gear 32 to rotate and displace on the inner gear ring 33;

[0031] Third, the rotating bevel gear set 35 drives the fan blade 36 to rotate through the connecting rod, and the airflow generated by the fan blade 36 takes out the heat generated by the internal components, thereby dissipating the heat of the internal components;

[0032] Fourth, the high-speed rotation of the input shaft is converted to the low-speed rotation of the transmission shaft 2. Here, the high-speed rotation input at the rear end of the transmission shaft 2 drives the planetary gear 32 to run through the sun gear 31. At this time, the high-speed rotation force consumes energy in the operation of the planetary gear 32 and the speed decreases. Then, the clutch at the end of the transmission shaft 2 is energized to generate magnetism and adsorbs the shaft body at its end that is plugged and fixed at the center of the bevel gear set 35 and rotates accordingly, thereby causing the bevel gear set 35 and the fan blades 36 to follow the rotation. Due to the resistance of the bevel gear set 35 and the fan blades 36 during operation, the input high-speed rotation energy is consumed again, thereby reducing the input high-speed rotation and outputting a low-speed rotation. Multiple sets of transmission parts are used to achieve multiple resistances to the output torque, thereby achieving multi-stage speed change, and the internal components are dissipated by the rotating fan blades 36, thereby improving the accuracy of the device during speed change.
