摘要：A toothed belt power transmission system includes a toothed belt havingevenly spaced teeth adapted to mesh with evenly spaced teeth on a toothed pulley forpower transmission. The belt teeth have a curved engagement surface including aconvexly arcuate tip portion and a concavely arcuate root portion that come in sliding
contact with a concavely arcuate root portion and a convexly arcuate tip portion,respectively, of a curved engagement surface of the pulley teeth in such a manner that aspace is defined between the confronting engagement surfaces of the belt and pulleyteeth. By virtue of the space thus formed, air confined between the belt tooth and pulleytooth is allowed to escape in the transverse direction of the belt and does never producebursting sound at the mesh of the belt tooth with the pulley tooth. In this instance, theair serves also as a pneumatic damper and thus suppresses the impact force.
