Camshaft
Description :
The camshaft is a mechanical component of an internal combustion engine.
It opens and closes the inlet and exhaust valves of the engine at the right
time, with the exact stroke and in a precisely defined sequence. The
camshaft’s driven by the crankshaft by way of gearwheels, a toothed belt or
a timing chain. With a transmission ratio of 2:1, the rate of rotation of the
camshaft is half that of the crankshaft
Camshafts are made from the following materials.
– Grey cast iron
– Ductile cast iron
– Heat-treated steel
– Nitrided steel
They can be of hollow design to save weight. Their bearings and the cam tracks are usually surface-hardened are available separately or as a kit. In addition to the camshaft, kits include the corrosponding bucket tappets, rockers or rocker arms.
