 note = {application/pdf, The novel mechanism CVT (Shaft Drive CVT, S-CVT) was developed by the authors. The improvement of power to weight ratio, namely the increase of transmitted power with downsizing and lightening of the transmission is important applying the S-CVT to automobiles. The concave disk/roller to reduce the slip ratio were devised and their effect to improve the efficiency was confirmed by the experiment, but the contact pressure was a little large and limited the torque capacity. The new curved disk/roller named the zero-spin disk/roller was devised in this paper. The spin decreased to less than 0.9% at all speed ratio and the contact pressure was also decreased comparing with the concave one. The optimum design of zero-spin disk/roller to satisfy the torque capacity of 150 Nm was achieved using the power to weight ratio as the evaluation function. The allowable Hertzian pressure is set as 4 GPa. The power to weight ratio of zero-spin and concave disks/rollers becomes 2.3 and 1.7 kW/kg, respectively. It is improved 36% and the effectiveness of zero-spin disk/roller is confirmed.},
