Abstract

DC60 (06/06/40) In a V-shaped metal continuous belt transmission unit with the driven flywheel and the driven flywheel, the alpha bevel of the V-shaped groove in the flywheel is set. In the range represented by tan-1 mu a &lt; Alpha &lt; tan-1 mu s, where mu s represents the static friction coefficient between the flywheel and the continuous belt and mu a represents the coefficient. Kinetic friction between the flywheel and continuous belt In a continuously variable transmission transmission belt Conventional V-shaped continuous metal that alpha bevel is set in the range represented by alpha &gt; tan-1 mu s If the tin forwarding torque is increased by Tin The continuous belt shear will also increase and Resulting in a slip between the continuous belt and the flywheel. By increasing the alpha bevel to reduce the shear force of the continuous belt; The torque transmission torque of the Tin can be increased while preventing the slippage of the continuous belt. In a V-shaped metal continuous variable transmission unit with a driven flywheel and a driven pulley, the alpha angle of the V-groove in the pulley is set to the range represented by tan-1. Mew a &lt; Alpha <tan-1 mu s where mu s represents the static friction coefficient between the flywheel and the continuous belt, and mu a represents the coefficient. Kinetic friction between the flywheel and continuous belt In a continuously variable transmission transmission belt In conventional V-shaped continuous metal, the alpha bevel will be set in the range represented by alpha> tan-1 mu s if the Tin forward torque is increased. The continuous belt shear will also increase and Resulting in a slip between the continuous belt and the flywheel. By increasing the alpha bevel to reduce the shear force of the continuous belt; The torque transmission torque of the Tin can be increased while preventing the slippage of the continuous belt.
