PURPOSE:To reduce backlash while to prevent pitching due to Hertz stress by constructing the gear in gear transmission system with main and sub-gears while arranging a repellent weight member movably between the holding faces of both gears. CONSTITUTION:The gear 7 is constructed with main gear 17 and sub-gear 18 to arrange a repellet weight member 21 between the holding faces 19d, 20d of both gears 17, 18. Since the centrifugal force caused through rotation of gear 7 will cause the weight member 21 to rotate main gear 17 relatively against sub-gear 18, backlash can be reduced reliably over the entire region for the gear transmission system having high torque fluctuation. While impact between the gears is relieved through spring function of the weight member 21 to prevent pitching due to Hertz stress applying onto respective gear face. |
