[0040] Example 1

[0041] Please refer to Figure 1-10An integrated planetary carrier assembly includes a planetary carrier 1 and a planetary gear 12. The outer side of the planetary carrier 1 is provided with a mounting groove 11, and three mounting grooves 11 are provided in a circumferential array. The planetary gear 12 is placed on the surface of the mounting groove 11. The inside of the planetary carrier 1 and the planetary gear 12 is provided with mounting holes, and a fixed shaft 13 is slidably connected to the inner surface of the mounting hole. The planetary gear 12 is rotatably arranged on the outer surface of the fixed shaft 13. A positioning hole 2 is provided on the lower surface of the planetary carrier 1, and a positioning member for quickly installing the planetary gear 12 is slidably connected to the inner surface of the positioning hole 2. A rotating groove 3 is provided inside the planetary carrier 1, and a fixing member for fixing the fixed shaft 13 is rotatably connected to the inner surface of the rotating groove 3. The positioning member includes a positioning frame 21, and six positioning holes 2 are provided in a circumferential array. The positioning hole 2 extends to the inner top surface of the planetary carrier 1, and the positioning frame 21 is slidably arranged inside the positioning hole 2.

[0042] Implementation process: manually place the planetary carrier 1 upside down on the ground, then place the positioning frame 21 on the inner side of the mounting groove 11 through the positioning hole 2, and then put the planetary gear 12 into the mounting groove 11, so that the planetary gear 12 contacts the two inner sides of the positioning frame 21. At this time, the inside of the planetary gear 12 is opposite to the mounting hole opened in the planetary carrier 1, insert the fixing shaft 13 into the inside of the mounting hole, and then slide the positioning frame 21 out from the inside of the positioning hole 2, repeat the above operation until the positions of the three planetary gears 12 are all fixed, and manually invert the planetary carrier 1 with its front side facing up.

[0043] Implementation benefits: The position of the planetary gear 12 is fixed.

[0044] Example 2

[0045] The fixing member includes a rotating plate 31, which is rotatably arranged inside the rotating groove 3. An inclined surface 32 is provided on the outer side of the rotating plate 31, and three inclined surfaces 32 are provided in a circumferential array. A fixing groove 33 is provided on the outer surface of the fixed shaft 13, which is located on one side of the inclined surface 32. The fixing groove 33 is connected to the inclined surface 32, and a fixing block 34 is slidably connected to the inner surface of the fixing groove 33. A roller 35 is rotatably connected to the inner side surface of one end of the fixing block 34 through a rotating shaft, and the roller 35 is rolled on the surface of the inclined surface 32. A sliding groove 4 is provided inside the rotating plate 31 below the fixing block 34, and a spring 41 is fixedly connected to one side of the inner surface of the sliding groove 4. A slider 42 is fixedly connected to one end of the spring 41. The slider 42 is slidably arranged inside the sliding groove 4, and the upper surface of the slider 42 is fixedly connected to the lower surface of the fixing block 34. A movable groove 5 is provided on the upper surface of the planetary carrier 1, and a connecting block 51 is slidably connected to the inner surface of the movable groove 5. The connecting block 51 is fixedly connected to the rotating plate 31. Two threaded holes 52 are provided on one side of the movable groove 5 on the upper surface of the planetary carrier 1. The threaded holes 52 pass through the connecting block 51, and bolts 53 are threadedly connected to the inner surface of the threaded holes 52.

[0046] Implementation process: Turn the bolt 53 to disengage the bolt 53 from the inside of the threaded hole 52, then pull the connecting block 51 to the left to make the connecting block 51 slide inside the movable groove 5, and the sliding of the connecting block 51 drives the rotating plate 31 to rotate clockwise inside the rotating groove 3. Because the roller 35 is rollingly arranged on the surface of the inclined surface 32, the rotation of the inclined surface 32 drives the roller 35 and the fixed block 34 to move inside the fixed groove 33 toward the direction of the fixed shaft 13, and at the same time drives the slider 42 to move synchronously and compress the spring 41. When the fixed block 34 slides to the fixed groove 33 inside the fixed shaft 13, the connecting block 51 slides to the leftmost end of the movable groove 5. At this time, the position of the bolt 53 is opposite to the position of the threaded hole 52 on the left. Rotate the bolt 53 in the opposite direction to make the bolt 53 engage with the threaded hole 52 again, thereby fixing the position of the connecting block 51 and the rotating plate 31, and then fixing the position of the fixed shaft 13.

[0047] Implementation benefits: The position of the fixed shaft 13 is fixed.

[0048] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
