MOTORCYCLE CAMSHAFT (NOKENS ASSY)

Hmmm .... The discussion this time I tried to draw one of the components of the engine that is still associated with the valve shaft nok (camshaft) what functions and where the location of the shaft component, please read the following posts ..
Camshaft is a tool used in the machine for run poppet valve. It consists of a cylindrical rod. Cam open the valve by pressing it, or with the help of the mechanism other, as they rotate. The relationship between the rotation of the camshaft rotation axis crank is very important. Since the valves control the flow of material inputs burn and spending, they must be opened and closed at the moment appropriate for the pistons. For this reason, the camshaft directly connected to the crankshaft (through the mechanism gear) or indirectly through a chain called "chain time ".

Figure 1. MOTORCYCLE CAMSHAFT

In a two-cycle engine that uses a camshaft, each valve is opened once for each rotation of the crankshaft in the engineThis, the camshaft rotates at the same speed as the crankshaft. In a four stroke engine the valves will open half less, therefore two full rotations of the crankshaft occur in each rotation of the camshaft. Sliding friction between the front of the cam follower depending on the amount of friction. To reduce this wear, cam and the follower has a hard surface, and lubricants Modern-containing materials that specifically reduces friction glide. Lobe (ears) of the camshaft usually tapered, resulted follower or valve lifter rotates slightly in each pressure, and make the wear components. Usually the face of cam and follower are designed to wear together, so when one have worn then both should be replaced to prevent wear excessive.
