Abstract
A backlash reducer for a gear transmission system comprises a main gear and an auxiliary gear which form one of a driving gear and a driven gear in mesh therewith of the gear transmission system. The main gear is mounted on a rotary shaft for rotation therewith, and the auxiliary gear is mounted on the rotary shaft for rotation relative thereto. A backlash reducing mechanism is operable in response to a centrifugal force due to rotation of the rotary shaft for angularly moving the main and auxiliary gears relative to each other to reduce a backlash between the driving and driven gears. The backlash reducer may further comprise a mechanism for restraining the backlash reducing action of the backlash reducing mechanism. Alternatively, the backlash reducer may comprise a first mechanism operable in response to the centrifugal force to move the auxiliary gear axially thereof and a second mechanism for converting the axial movement of the auxiliary gear to circumferential movement thereof.
