ABSTRACT:
A continuously variable speed transmission mechanism comprises a tubular input shaft connected at an end to an input unit, an output shaft positioned coaxially with the input shaft, connected at an end to an output unit and extending at the other end into the hollow part of the input shaft, an input disk rotatably mounted on the output shaft and adapted to rotate by the driving force transmitted from the input shaft, an output disk fixed on the output shaft and adapted to rotate by the driving force transmitted from the input disk through power rollers, and a thrust bearing positioned between the other end of the output shaft and a corresponding part of the input shaft thereby enabling mutual rotation of the shafts. Wherein the reactive force applied to the input disk at the transmission of driving force is received by the thrust bearing through the input shaft, while the reactive force applied to the output disk is also received by the thrust bearing through the output shaft.
