Patent ID: 8277345

Claim:
A stepless transmitting and speed-varying structure comprising: a power mechanism driving a first transmission shaft, with the first transmission shaft connected with a set of disk members, with the set of disk members including a fixed disc and a movable disc; a transmitting mechanism including a belt disposed on the set of disk members, with one end of the belt connected with an intermediate speed-varying stem, with the intermediate speed-varying stem being coaxial with a transmitting member moving a second transmission shaft, with the second transmission shaft including a resilient member, with one end of the resilient member coupled with the intermediate speed-varying stem and with another end of the resilient member connected with a fixed member; and a speed varying mechanism including the second transmission shaft connected with a variable speed member and an actuated member and including a plurality of eccentric blocks mounted around a peripheral side of the variable speed member and moveable relative to the variable speed member, with the variable speed member coupling with a connecting rod, with one end of the connecting rod joined with the movable disc of the set of disk members.
