Rancang Bangun Mesin Replika Camshaft Sepeda Motor
Abstract
The camshaft is a component in the piston engine which functions to open and close the valve in accordance with the ignition timing sequence. Camshaft duration is very important to determine the length of the opening and closing time of the valve, the duration of the camshaft can change due to changes in the size of the camshaft profile, changes in the size of the camshaft profile due to continuous friction between the camshaft profile and the valve trigger. This study discusses a motorcycle camshaft replica machine that can reshape the camshaft profile, by adding metal material to the camshaft profile to be repaired, adding material by SMAW welding and reshaping the profile by grinding. Where a similar intact camshaft is used as a guide for the formation of the camshaft profile to be repaired. In this study, 2 types of grinding wheel roughness were used, namely, grit 100 and grit 120. In this study the method used was design, and from the research, the results of the vibration test produced by the machine were 6.29 mm/s on average. The surface roughness of the repaired camshaft profile that was ground with a 100 grit grinding wheel was coarser with a roughness value = 1.174 µm at point 1 and at point 2 = 1.301 µm. The surface roughness of the repaired camshaft profile which was ground with a 120 grit grinding wheel was smoother with a roughness value = 0.989 µm at point 1 and at point 2 = 0.762 µm.Published
