In this study, the frictional behaviors of cam
mechanisms, the important functional parts of engines, are investigated.
Knowing the frictional behavior and decreasing of it at the contact region
betvveen cam and tappet are very important in the cam mechanism transmitting
motion. A new measurement method is therefore developed and frictional forces
at the contact region are also measured. The normal force and its components
for two different revolutions are measured. The measurement of frictional force
is achieved using the measurement table attached to a measurement beam which is
connected rigidly to the part that the normal force acts on. The friction
coefficients are determined using frictional and normal forces. In this
research, the normal forces, the frictional forces and the friction
coefficients are comparingly given for five different oils under the same
working conditions.
