[0002] Planetary gears refer to a gear system that can rotate around its own axis like fixed axis gears, and its axis can also rotate around the axis of other gears along with the planet carrier. Rotation around its own axis is called "rotation", and rotation around the axis of other gears is called "revolution", just like the planets in the solar system, hence the name. Compared with ordinary gear transmission, planetary gear transmission has many unique advantages. The most notable feature is that power can be split when transmitting power, and the input shaft and output shaft are on the same horizontal line. Therefore, planetary gear transmission has been widely used in reducers, speed increasers and speed change devices in various mechanical transmission systems.

The threaded rod 1203 is sleeved inside the convex plate 1201, and a limiting piece 1204 is fixedly connected to the outer side of the threaded rod 1203.

[0022] Furthermore: The staff only needs to rotate the threaded barrel 1202 to drive the movement of the collar 2201 to complete the fixation or disassembly of the planetary gear 4, enabling the staff to quickly complete the assembly or disassembly of the planetary gear structure. After the internal structure of the planetary gear is damaged, it can be directly replaced without affecting the use of the planetary gear, thereby improving the overall service life of the planetary gear.

[0023] Embodiment 2 Refer to Figures 1 to 4, and on the basis of the first embodiment, it is further obtained that the clamping mechanism 2 includes a rotating component 21, a clamping component 22, and a limiting component 23. The rotating component 21 is arranged inside the front and rear sides of the planet gear 4, the clamping component 22 is arranged outside the rotating component 21, and the limiting component 23 is arranged outside the clamping component 22.

[0024] The rotating component 21 includes a slider 2101. The slider 2101 is rotatably connected inside the front and rear sides of the planet gear 4. A moving slide rod 2102 is fixedly connected to the outside of the slider 2101. The moving slide rod 2102 is slidably connected inside the front and rear sides of the planet gear 4.

A convex rod 2104 is fixedly connected to the outside of the sliding piece 2103. The clamping component 22 includes a collar 2201. The collar 2201 is sleeved on the outer circle of the convex rod 2104. A connecting plate 2202 is fixedly connected to the inner side of the collar 2201. The limiting component 23 includes a limiting slide rod 2301. The limiting slide rod 2301 is fixedly connected to the outside of the connecting plate 2202. The connecting plate 2202 is slidably connected inside the convex plate 1201. A limiting plate 2302 is fixedly connected to the outer circle of the limiting slide rod 2301. A connecting rod 2303 is fixedly connected to the inner side of the limiting plate 2302. The connecting rod 2303 is fixedly connected to the outside of the collar 2201.

[0025] Furthermore: The collar 2201 is sleeved on the outer circle of the convex rod 2104 to limit the position of the planet gear 4 on the front and rear sides of the planet gear 4, so that the planet gear 4 cannot be separated from the connection relationship with the ring gear 5 during use, increasing the overall structural stability of the planet gear. At the same time, the limiting slide rod 2301 is slidably connected inside the convex plate 1201 to limit the collar 2201 through the connecting plate 2202, increasing the structural stability of the collar 2201 and the connecting plate 2202. At the same time, the threaded rod 1203 fixed to the outside of the connecting plate 2202 cannot rotate, so that the threaded rod 1203 can only move following the rotation of the threaded barrel 1202, and the operation is simple and convenient for the staff to use.

[0026] In actual operation, when the device is used, when the planetary gear needs to be spliced, the staff first places the planetary gear 4 on the inner ring of the gear ring 5, so that the planetary gear 4 and the inner ring of the gear ring 5 are meshed while keeping the spacing between them equal. Then the staff inserts the sun gear 3 into the inner position of the planetary gear 4, so that the outer ring of the sun gear 3 and the outer ring of the planetary gear 4 are meshed with each other. Then the staff moves the protruding rod 2104 and the collar 2201 to align them with each other. Then the staff rotates the threaded drum 1202. The threaded drum The rotation of 1202 drives the threaded rod 1203 to move inward, and the threaded rod 1203 moves inward and drives the ring 2201 to move inward through the connecting plate 2202. The ring 2201 moves inward and is sleeved on the outer ring of the protruding rod 2104 to complete the positioning of the slider 2101. After the positions of the sliders 2101 on the front and rear sides are fixed, the planetary gear 4 is fixed, so that the planetary gear 4 can only rotate on the inner ring of the gear ring 5, and cannot be separated from the connection relationship with the gear ring 5 forward or backward. At this time, the splicing of the planetary gear is completed.
