ABSTRACT:
The invention provides a friction type continuously variable speed changing mechanism having a construction suitable for applications in which it is used to continuously change the speed of an output shaft for driving a high speed rotating body, such as the vane wheel of a centrifugal blower or the like.
This continuously variable speed changing mechanism comprises an input shaft 11 internally contacted by a plurality of cones 27 held for rotation and revolution, an output shaft 15 externally contacted by the plurality of cones 27, a pressing spring 19 for applying an elastic pressing force between the input and output shafts 11, 15 and the plurality of cones 27, and a speed changing ring 26 slidably pressed against the cones 27, the arrangement being such that the power is transmitted between the input and output shafts 11, 15 through the rotation and revolution of the cones 27 and the speed at which the power which is being transmitted is continuously changed by the sliding movement of the speed changing ring 26, said continuously variable speed changing mechanism further includes a cone holder 28 which comprises a cone supporting shafts 30, and a holder body 29 in which the cone supporting shafts 30 supporting the cones 27 are integrally disposed equally spaced circumferentially.
