This law produces finite jerk throughout the segment. It also produces a relatively low nominal peak velocity, but a relatively high peak nominal acceleration. This Motion-Law also has a relatively low jerk value at the cross-over point (the mid-point).
This Motion-Law is recommended in applications where the period ratio is between 5 and 10, particularly where the input drive is flexible with backlash. Residual Vibration is less than many other laws.
Pressure Angle Considerations
This one of the Traditional Motion-Laws that produce 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 very good for this law. The low peak values and smooth variation of the drive torque during the motion segment further emphasise the suitability of this Motion-Law in applications where the input drive is flexible or exhibits backlash.
