[0002] Planetary carriers are commonly used in gearboxes and are one of the main components of planetary gear transmissions. They consist of a sun gear, several planetary gears, and a ring gear. The planetary gears are supported by the shaft of the planetary carrier, allowing them to rotate on the support shaft. The planetary gears and the adjacent sun gear and ring gear are always in constant mesh to ensure smooth operation.

[0003] In the existing technology, the commonly used planetary carrier structures in planetary gear transmissions include the following types: integral frame structure, welded casting structure, and cantilever structure with detachable side plates. Among them, the cantilever planetary carrier with detachable side plates is an assembly type, and its side cover plate can be disassembled to facilitate its assembly. The assembly method is that the planetary carrier is set in the housing, the planetary gears are sleeved on the shaft column provided on the surface of the planetary carrier, the sun gear is set inside the planetary gears and meshes with them, and then the cover plate is used to limit its position and the cover plate is fixed by screws.

[0004] However, the traditional process of fixing the cover plate with screws is not only time-consuming, but also requires auxiliary tools to lock it. When the cover plate needs to be removed, it affects the ease of disassembly, thus affecting the efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an assembled planetary gear carrier for a variable speed gearbox and its assembly method, in order to solve the problems mentioned in the background art, such as the long time-consuming process of fixing the cover plate with screws, the need for auxiliary tools to lock it, and the inconvenience of disassembly when the cover plate needs to be disassembled, thus affecting the efficiency improvement.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an assembled variable speed gearbox planetary carrier, wherein the assembled variable speed gearbox planetary carrier comprises;

[0007] The assembly housing is equipped with a limiting block inside the assembly housing. The surface of the limiting block is equipped with a positioning post, and the surface of the positioning post is provided with a limiting groove.

[0009] A hinge block is provided on the surface of the cover plate, and one end of the limiting plate is hinged to the hinge block, and a positioning groove is provided on the outer side of one end of the surface of the limiting plate.

[0010] Preferably, the limiting block is fixed to the inner wall surface of the assembly housing, and there are multiple limiting blocks that are evenly distributed. The assembly housing is equipped with a planetary gear carrier, and a shaft column is fixed to the surface of the planetary gear carrier. Planetary gears are sleeved on the shaft column and the planetary gears are located between two adjacent limiting blocks. The assembly housing is also equipped with a sun gear, which is located inside the planetary gears and meshes with them.

[0011] Preferably, the positioning post is fixed to the middle of the top surface of the limiting block, and the limiting groove is formed above the surface of the positioning post.

[0012] Preferably, the cover plate is disposed on the surface of the assembled housing, and the surface of the cover plate has a through hole, the through hole and the positioning post are corresponding, the end of the positioning post passes through the through hole, and the limiting groove is disposed on the outside of the cover plate.

[0013] Preferably, the surface of the cover plate has a limiting hole, which corresponds to the shaft post on the surface of the planetary gear carrier, and the end of the shaft post is located in the limiting hole, and the end of the shaft post is flush with the outer end face of the cover plate.

[0014] Preferably, the anti-detachment plate is located at the top of the spring, and the positioning block is fixed on the top surface of the anti-detachment plate, with the end of the positioning block penetrating through the surface of the cover plate, and the top of the positioning block being located in the positioning groove.

[0015] A method for assembling a planetary carrier gear in an assembled transmission gearbox includes the following steps:

[0016] Step 1: Limiting. A limiting plate is hinged to the surface of the cover plate. By rotating the limiting plate, it is locked into the limiting groove to limit the cover plate, thereby achieving the pre-positioning of the cover plate on the surface of the assembled housing, making it more convenient to fix.

[0017] Step 2: Fixing. The positioning block moves outward and engages in the positioning groove through the elastic support of the spring, thereby fixing the limiting plate and the cover plate. The fixing method is relatively simple and conducive to improving efficiency.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention proposes an assembled planetary gear carrier for a variable speed gearbox. The positioning block is pressed down to move into the adjusting groove. A limiting plate is rotated to engage with the limiting groove, thus limiting the cover plate. The positioning block is then loosened, allowing it to move outwards under the elastic support of a spring and engage with the positioning groove again, thus fixing the limiting plate. This completes the fixing of the cover plate. Pressing the positioning block down again and rotating the limiting plate in the opposite direction releases the limiting groove, thus releasing the limiting of the cover plate. The cover plate can then be removed from the assembled housing. The fixing and disassembly process is relatively simple and improves efficiency. Attached Figure Description
