摘要

The unit (1) has a set of ring gears (4) coaxially arranged to rotation axis and standing in connection with projection portions of spur gear pins (2a, 2b). Another set of ring gears (5) is coaxially arranged to the rotation axis and stands in connection with projection portions of the spur gear pins. A supporting element is provided at an inner space of the respective ring gears. A pin structure carries or supports over which a spur gear pin front-sided lining up is radially supported at respective supporting element.
