Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a planetary wheel positioning tool for an automobile gearbox. Background Art

[0002] The planetary wheel carrier is a casting widely used in mechanical equipment. After casting, the planetary wheel carrier needs to undergo a series of machining before it can be used. During machining, the planetary wheel carrier needs to be accurately positioned and fixed with the help of positioning tools to match the machining equipment. The existing planetary wheel carrier positioning tools need to be manually adjusted and repeatedly verified by humans during positioning. The operation is cumbersome, the work efficiency is low, and it is time-consuming and labor-intensive, which needs further improvement. The structural form of the planetary carrier depends largely on the use function, the method of manufacturing the planetary carrier, and the assembly conditions of the planetary gear reducer. A reasonable planetary carrier structure should have a small outer size and light weight, which can ensure uniform load distribution between the planetary wheels and uniform load distribution along the meshing tooth width, and have good processing technology and assembly technology, so that the planetary gear transmission has a high load-bearing capacity and less vibration and noise. At present, the commonly used planetary carrier structures in planetary gear transmission are of the following types: (1) integral frame structure; (2) welded structure and cast structure; (3) cantilever structure with detachable side plate; (4) single side plate planetary gear shaft; cantilever integral structure; (5) combined structure. In heavy-load planetary gear transmission, this structure is characterized in that the torque is input or output from the middle part of the support column, and the structure of the components for mounting the planetary gear shaft is symmetrical. At this time, if the planetary carrier support column and side plate are deformed, the planetary gear axis will be deviated relative to the center gear axis, thereby ensuring that the load is evenly distributed along the meshing tooth width.

[0003] The application number is 202122124467.5, which discloses a planetary wheel carrier positioning tool, including a base plate, a plurality of clamping mechanisms fixed to the left side of the top of the base plate and evenly arranged at equal angles along the circumferential direction, and a positioning mechanism arranged on the right side of the top of the base plate and cooperating with the plurality of clamping mechanisms; the positioning mechanism includes three support blocks fixed to the top of the base plate and arranged in sequence from left to right, a connecting block fixed to the right side of a support block on the far right, a traction cylinder fixed to the right side of the connecting block, and a main body interspersed in the three support blocks and movable left and right, but there are shortcomings in that the positioning structure is not convenient for the installation of the assemblies on both sides and the positioning structure is not provided with a fixing structure, and long-term use may cause the positioning structure to be unstable.
