CALCULATION OF WEAR VELOCITY IN PROFILE PART OF CAM

In the article, taking into account the increasing wear of the profile, the intensity of wear of the surface of the cam in contact with talc during operation is studied, and the change in this intensity depending on the pressure angle is estimated. The effect of chamber profile wear on the gas distribution mechanism (GDM) and engine operation has been studied. the possibility ofa significant improvement in the tribological properties of a cam-pusher pair is analyzed on the basis of a numerical method for formulating the law of motion of the pusher.
