Cycloidal-CV50 •Symmetrical •Position, Velocity and Acceleration Continuity •Finite, but four Jerk discontinuities. Motion-Law Coefficients •Velocity Coefficient: Cv = 1.33 •Acceleration Coefficient: Ca= 8.378 •Jerk Coefficient: Cj= ±105.276 •Jerk at Cross-Over 0.25 Cross-over@0.25 q: Cj(co)= ±105.276 (Effectively) Application Notes:Dynamic Performance This Motion-Law is recommended in applications where you need the peak velocity to be low when compared to others. It has a large Peak Acceleration, with a short duration, thus more likely to induce vibrations. Pressure Angle Considerations It gives a relatively low pressure angle - because of its low peak velocity. Drive Torques This Motion-Law is not recommended in many applications as it will give a sudden change in torque. The input transmission rigidity would need to be high. |
