摘要：Disclosed is a stepless speed change gear including a plurality of conical rollerseach of which is provided with a conical surface frictionally engaging with a ring-membermoved by a speed changing assembly. A surface of concave cross-section frictionallyengages with a sun-member on an input shaft, and a flat surface frictionally engages witha non-rotatable disc member. A gear train is provided to extend the speed range toinclude a speed ratio of 1:1. A release mechanism is provided for the non-rotatable discmember, and a clutch mechanism is provided for direct coupling of the input and theoutput shaft. Power is transmitted by direct coupling of the input and the output shaft.
