Description

Technical Field

[0001] This utility model relates to the field of planetary gear reducers, and in particular to a planetary gear needle roller assembly device. Background Technology

[0002] In some existing planetary gear reducers, needle rollers are installed on the inner side of the planetary gears. These needle rollers ensure smooth rotation and reduce wear. Currently, the installation of needle rollers onto the inner side of the planetary gears is done manually in conjunction with a needle roller assembly machine. The process is as follows: the operator first installs the planetary gear onto an assembly mold; then, the operator places the assembly mold (with the planetary gear attached) into the mounting station of the needle roller assembly machine, which then installs the needle rollers onto the inner side of the planetary gear; next, the operator removes the planetary gear with the needle rollers (defined as the planetary gear assembly) and the assembly mold from the mounting station of the needle roller assembly machine; finally, the operator removes the planetary gear with the needle rollers from the assembly mold. As can be seen, each step of the installation process requires operator intervention, resulting in high workload and low installation efficiency.

[0003] In view of the above problems, it is necessary to study a planetary gear needle roller assembly device that can improve the installation efficiency of needle rollers to planetary gears. Utility Model Content
