Gear driven camshaft for multicylinder IC engine - has enlarged dia. between end and intermediate bearing points to counteract bending

摘要

The camshaft consists of a stem with cams, two end bearings and an intermediate bearing, such that the cam shaft is driven at one shaft end via a flying gear. A dia.(D1) of the camshaft stem (9) is enlarged in a first section between the end bearing (7) and an intermediate bearing (8) to a dia.(D2), and the dia. of the basic circle (11) of the cam (10) is matched to the second dia. ADVANTAGE - Reduced shaft bending without need to change in engine block.
