Belts and Sheaves

Motion supplies a wide array of belts and sheaves for mechanical power transmission applications. These power transmission belts pair with sheaves and are used to transfer mechanical power. Belt types include V-belts, round belts, timing belts, and flat belts. V-belts have tapered cross-sections that lodge into the grooves of V-belt pulleys to transmit high torque and reduce slipping caused by under-tensioning. Round belts are used in pulleys with a 60-degree V-groove. Timing belts have external teeth that interlock with the teeth of timing belt pulleys. p p They are either single-sided or double-sided. Flat belts are used with pulleys that have crowned surfaces to prevent them from slipping under heavy loads. They have largely been replaced by V-belts and timing belts.
