Abstract
The invention provides a cone belt type stepless speed change device. According to a cone with mutually-inverted parallel axes, through a tension device, a transmission belt tightly wraps the two outer sides of the cone, and the friction between the transmission belt and the cone is utilized to transmit power. Through a speed adjusting device, the position of the transmission belt on the cone is changed so as to realize changes of different speed ratios. Due to the fact that the position of the transmission belt on the cone is consecutive, stepless speed change can be realized. The cone belt type stepless speed change device has the advantages of being simple in structure, capable of changing speed in a stepless mode, and large in the range of torque capable of being transmitted.
