【Abstract】 A new theory of rolling screw retarding mechanism with dual lead is proposed,and the reduction ratio equation and the transmission efficiency equation of the mechanism are derived. Kinematical analysis and computation has proved that the mechanism has a large reduction ratio and high transmission efficiency. The new dual lead rolling screw mechanism has been already applied to door operator of bus,and also has a broad application prospect in machinery,food,pharmacy and many other fields.更多还原
