[0002] Planetary gears refer to gear systems that can rotate around their own rotation axes like fixed axis gears, and their rotation axes can also rotate around the axes of other gears along with the planet carrier. 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 is now widely used in reducers, speed increasers and speed change devices in various mechanical transmission systems.

[0003] The planet carrier is one of the main components of the planetary gear transmission device. The planetary shaft or bearing is installed on the planet carrier. When installing the planetary gear, the planetary gear is installed through the preset tooth grooves of the planet carrier. However, the height of the planet carrier is mostly fixed. Therefore, when installing the planetary gear, only planetary gears of fixed thickness can be installed. It is impossible to make corresponding adjustments according to the thickness of the different planetary gears installed, which limits the installation range of the planet carrier and makes the overall installation inconvenient. Therefore, how to make the planet carrier adjust accordingly according to the thickness of the different planetary gears installed is an important problem that needs to be solved in the design of planetary gears.

[0042] The adjusting structure 5 includes a rotating gear 501, a threaded sleeve 502 and a threaded rod 503. The threaded rod 503 is fixedly connected to the inner wall of the sliding groove 7. The threaded sleeve 502 is threadedly connected to the threaded rod 503. The threaded sleeve 502 is rotatably connected in the sliding groove 7. The rotating gear 501 is fixedly connected between the threaded sleeves 502.

[0043] The rotating gear 501 drives the threaded sleeve 502 to rotate, and the rotation of the threaded sleeve 502 drives the threaded rod 1 503 to move.

[0044] The threads on the threaded rod 1 503 on both sides of the rotating gear 501 are opposite.

[0045] The threaded rods 503 on both sides move in opposite directions, and the movement of the threaded rods 503 pushes the two planet carriers 3 to move, so that the two planet carriers 3 move closer to each other or farther away from each other.

[0046] The limiting structure 6 includes a sliding ring 601 and a limiting groove 602 . The sliding ring 601 is fixedly connected to the outer wall of the planet carrier 3 . The side wall of the sliding ring 601 is provided with rectangular limiting grooves 602 at equal distances.

[0047] The rotating structure 4 includes a rotating ring 401 and a rotating gear ring 402. The rotating ring 401 is slidably connected to the sliding ring 601.

The rotating gear ring 402 is slidably connected between the two planet carriers 3.

[0048] The rotating ring 401 is rotated, and the rotating ring 401 drives the rotating gear ring 402 to rotate, and the rotating gear ring 402 drives the rotating gears 501 distributed at equal distances to rotate synchronously.

[0049] The rotating gear ring 402 and the rotating gear 501 are meshed with each other.

[0050] The side wall of the rotating ring 401 is provided with a second sliding groove 9, a first placement groove 10 and a second placement groove 11 at equal distances, and the second sliding groove 9, the first placement groove 10 and the second placement groove 11 are connected to each other.

The limiting rod 802 is fixedly connected to the side wall of the fixed block 801, and the limiting rod 802 is slidably connected in the sliding groove 2 9.

[0052] The rotating block 804 is rotated, and the rotating block 804 drives the second threaded rod 803 to move, pushing the fixed block 801 out of the second placement groove 11 and engaging into the corresponding limit groove 602, which can better limit the column rotating ring 401 and prevent the rotating ring 401 from rotating.

The sleeve 502 rotates, and the threaded sleeve 502 rotates to drive the threaded rod 1 503 to move. Since the threads on the threaded rod 1 503 on both sides of the rotating gear 501 are opposite, the threaded rod 1 503 on both sides move in opposite directions. The movement of the threaded rod 1 503 pushes the two planet carriers 3 to move, and the two planet carriers 3 move closer to or farther away from each other, so that the distance between the two planet carriers 3 can be adjusted according to the thickness of the planetary gear 2 to be installed, so that the planet carrier 3 can be suitable for the installation of planetary gears 2 with different thicknesses, making the installation more convenient;

[0056] Then rotate the rotating block 804 in the opposite direction, and the rotating block 804 drives the threaded rod 2 803 to move, pushing the fixed block 801 out of the placement groove 2 11 and snapping into the corresponding limit groove 602, so as to better limit the column rotating ring 401 and prevent the rotating ring 401 from rotating.
