<p>A motion transmitting apparatus includes a driving gear (202), a rotating shaft (201), a first driven gear (3) sleeved fixedly on the rotating shaft (201), and a gear clearance eliminating device. The gear clearance eliminating device includes a second driven gear (4) sleeved rotatably on an annular flange (31) of the first driven gear (3), at least one spring (6) disposed among the first and second driven gears (3,4) and an assembly of the first and second driven gears (3,4), a ring plate (7), and a C-shaped retaining ring (5) for retaining the ring plate (7) on the annular flange (31) . At least one oil-receiving groove (33) is formed in the annular flange (31), crosses the positioning groove (34), and has an inner end aligned with the second driven gear (4).</p> |
