IMPROVEMENTS RELATING TO GEAR MECHANISMS

摘要

A gear mechanism (2) comprising: a rotatable member (22); a track member (24); a first axle member (40) disposed on the rotatable member (22); a first gear member (26) adapted to rotate on the first axle member (22), and rotatably track along the track member (24), during rotation of the rotatable member (22); and a second gear member (28) adapted to be linked with the first gear member (26) so as to enable transmission of motion between the first and second gear members (26 & 28).
