  • Abstract Roller Gear Cam mechanism(RGC)has been used widely in different automation mechanisms and all kinds of orientation mechanism. High speed and high accuracy of the RGC system is a tendency in high production automation. The interaction between the driving speed and torque of a high speed RGC system is investigated in this work. The effect of adding a torque compensation cam(TCC)on the improving of indexing precision of a RGC system is investigated in this thesis.
    The dynamic responses of a RGC system driven by a DC motor are conducted. Dynamic equations of the intermittent- motion of a RGC driven system are derived by using the Lagrange’s equation with the assumption of dual-stiffness. Furthermore, the effect of adding a torque compensation mechanism(TCM) such as torque compensation cam(TCC) or idle wheel on the improving of indexing precision of a RGC system is investigated in this work. The sixth order Runge-Kutta iteration method is employed in the system’s responses simulation. Variations of the driving torque, driving speed and residual vibration of a RGC system with different torque compensation devices are analyzed in this research.
    The simulated and measured results indicate that a RGC system attached with a TCC can improve its speed and torque fluctuation at the designed speed significantly. However, this compensation effect is quite sensitive to the driving speed. On the contrary, the compensation effect introduced by using an idle wheel is not so sensitive to the speed as the TCC does. The low cost and easy design are also the favorable factors for using an idle wheel to instead of an expensive TCC device.
