[0032] By installing the rotating piece 502 and the threaded rod 503 on the back of the planetary gear 4, the rotating piece 502 can be moved in a rotating manner, so that the threaded rod 503 moves under the action of the thread and moves the connecting piece 506 through the lug 504. Since the planetary gear 4 is connected to the connecting piece 506 by bolts, when the position of the connecting piece 506 changes, the planetary gear 4 will also move, thereby solving the problem that the position of the planetary gear 4 on the surface of the planet carrier cannot be changed, which limits the use of the speed reducer.

[0033] The connecting assembly 6 includes a gear ring 601, a sliding rail 602, and a limiting piece 603. The gear ring 601 is installed inside the housing 1 and engages with the planetary gear 4.

This facilitates the replacement of the gear ring 601 by the operator and ensures that the gear ring 601 can be applied to planetary gears 4 at different positions.

[0035] The working principle of the high-pressure-resistant speed reducer planet carrier is as follows: when the position of the planetary gear 4 needs to be adjusted, the structure inside the housing 1 is removed, then the corresponding size of the gear ring 601 is installed by sliding and fixed by bolts. After the gear ring 601 is fixed, the planetary gear 4 is fixed to the connecting piece 506 by bolts through rotation. Then, the rotating piece 502 is rotated to move the lug 504 and the connecting piece 506 under the action of the thread, so that the planetary gear 4 changes position through the connecting piece 506. After the installation of the planetary gear 4 is completed, the corresponding size of the sun gear 3 is installed at one end of the output shaft 2 by bolts, and the position of the planetary gear 4 is changed.
