The wrap contact drive, especially a camshaft chain drive in an engine, has the camshaft revolving at half crankshaft speed. The number of teeth on the driving wheel (18) on the crankshaft (30), the number of teeth on intermediate wheels (24,32,26,44) and number of teeth on the camshaft wheel (36,42,48,50) are designed in relation to one another so that the drives (12,14,16) rotate with differing order and with a transmission ratio not equal to 1 and 2. |
