Abstract: In this paper，the benefit and feasibility of adopting oscillatory follower made of aluminum alloys for use in high-speed disk cam mechanisms are systematically delibrated. As aluminum alloys, suitably heat- treated, possess enough strength and sufficient hardness, oscillatory followers and rollers of the high- speed disk cam mechanism can be made of them. As the aluminum alloys have their densities of only a third that the steels, substintuting steels in oscillatory followers by aluminum alloys will materially reduce the thrust caused by the inertia force and couple of the oscillatory followers. A considerable reduction of the thrust of the oscillatory followers is very- helpful in increasing the working efficiency of the disk cam mechanism, reducing the noise, mitigating the vibration and in decreasing wear and tear of the cam profile and the roller.
