BACKLASH REDUCING DEVICE FOR GEAR TRANSMISSION SYSTEM

PURPOSE:To reduce a meshing noise, by providing two means, which relatively turn both a main gear and a subgear in accordance with centrifugal force so as to reduce backlash between a driving side gear and a drive side gear, between the main gear and the subgear. CONSTITUTION:A driving side idle gea...

Summary:PURPOSE:To reduce a meshing noise, by providing two means, which relatively turn both a main gear and a subgear in accordance with centrifugal force so as to reduce backlash between a driving side gear and a drive side gear, between the main gear and the subgear. CONSTITUTION:A driving side idle gear 7, comprising a main gear 17 and a subgear 18, contains a weight member 21, movably along a diametric direction of the main gear 17, between one holding surface B and the other holding surface A. The weight member 21, moving to the peripheral side by centrifugal force to relatively turn the main gear 17 and the subgear 18, reduces backlash. While a magnet 22, provided in each groove 19 of the main gear 17, attractively attaches the weight member 21 to the center side of the main gear 17 when the weight member generates small centrifugal force. Consequently, the backlash can be surely reduced over the total range from a low speed to a high speed.
