This paper describes a new low-cost CVT micro-traction-drive system utilizing commercially available tapered bearing. Driving low-cost type CVT to be able to adjust preload were done by arranging loading cam of slipping method combined back to back, and the following results were obtained. (1) The expression from which the rotational speed and the flow of power of developed low-cost type CVT micro-traction-drive system was clarified. (2) Preload generated when the load torque is 9Nm is about 1200N, and it agreed to the value of expectations of the assumption of the coefficient of friction on the cam surface 0.12. (3) Hysteresis phenomenon by friction on the cam surface is generated when the load torque is increased and when it decreases. (4) Hysteresis phenomenon become small since the coefficient of friction was decreased by putting Teflon film on the cam surface, and it was confirmed that the coefficient of friction was a important factor of hysteresis.
