This Motion-Law is recommended for applications where the period ratio is between 5 and 10, particularly where the input drive is flexible and has backlash. It also performs relatively well from a residual vibration viewpoint.
Pressure Angle Considerations
This is a Traditional Motion-Law that produces a relatively small pressure angle - and so might allow a smaller cam for a given lift and pre-prescribed maximum pressure angle.
Both the nominal drive torque characteristics and the actual drive torques for low period ratio values are reasonable for this law. The peak values and smooth variation of the drive torque during the motion segment makes it suitable in applications where the input drive is relatively flexible or exhibits backlash.
