[0030] Three gears of different sizes are fixed on the speed change gear 29, and the three gears of different sizes can rotate independently;

[0031] The first connecting gear 28 is in the shape of a trapezoidal circle;

[0032] The servo motor 21 is fixed on the left side of the reducer body 1 .

[0033] The reduction assembly 6 includes an input gear 61, which is meshed with a second connecting gear 62, a rotating shaft 66 is fixed in the second connecting gear 62, a small gear 63 is fixed at one end of the rotating shaft 66 away from the second connecting gear 62, the small gear 63 is meshed with a large gear 64, a reduction gear 65 is fixed on the right side of the large gear 64, the reduction gear 65 is meshed with a speed change gear 29, and an output shaft 68 is fixed in the speed change gear 29;

[0034] Second bearings 67 are fixed at both ends of the rotating shaft 66, and the second bearings 67 are fixed in the bearing grooves 5;

[0035] There are six groups of bearing grooves 5, which are symmetrically arranged on both sides of the reducer body 1, and second bearings 67 are fixed in the bearing grooves 5;

[0036] A second bearing 67 is fixed in the annular hole 4 , and lubricant is added inside the second bearing 67 .

[0037] In this embodiment, the output end of the speed change assembly 2 drives the sliding block 24 to move in a directional manner on the transmission screw 22, so that the hydraulic rod 25 extends the first connecting gear 28 to a suitable position according to the required torque change, and then meshes with the gear of the corresponding model and size in the speed change gear 29, so that the output shaft 68 can perform corresponding torque conversion, which is convenient for the reducer to respond to changes in the output torque and make corresponding adjustments in time.

[0038] Embodiment 2:

[0039] See also Figure 1-4This embodiment provides a technical solution based on the first embodiment: the disassembly assembly 3 includes a disassembly plate 31, and connecting plates 32 are fixed on both sides of the disassembly plate 31, and bolts 33 are fixed in the connecting plates 32.

[0040] In this embodiment, by fixing the disassembly plate 31 on the reducer body 1, when lubricant needs to be added to the gears in the reducer, there is no need to disassemble the entire reducer. It is only necessary to remove the bolts 33 fixed on both sides of the disassembly plate 31 so that the disassembly plate 31 can be removed and lubricant can be added to the internal gears.

[0041] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0042] During operation, firstly, the reduction assembly 6 is connected to the corresponding required motor. When the motor is started, the torque is transmitted to the second connecting gear 62 through the input gear 61, and then transmitted to the large gear 64 through the small gear 63, and finally transmitted to the speed change gear 29 by the reduction gear 65. When the torque required to be output by the reducer needs to be changed during operation, the output end of the servo motor 21 drives the sliding block 24 to move in a directional manner in the transmission screw 22, so that the first connecting gear 28 moves to a suitable position, and then the first connecting gear 28 is extended to a position where it is meshed and connected with the corresponding gear in the speed change gear 29 through the hydraulic rod 25, so that the output torque is transmitted through the speed change gear 29. The speed gear 29 changes speed, and then the output torque is transmitted to the output shaft 68 through the output gear 210 meshingly connected to the end of the first connecting gear 28 away from the speed gear 29, so that the torque output from the output shaft 68 is the same as the output torque value that needs to be changed. When the reducer is used for too long, the bolts 33 fixed on the top of the reducer body 1 are removed, so that the disassembly plate 31 is removed from the top of the reducer body 1. The staff drips lubricant into the gears inside the reducer through the position where the disassembly plate 31 is removed. The lubricant will be meshed between the gears, so that the gears in the entire reducer are coated with lubricant, thereby extending the service life of the reducer.
