Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2009243571
Kind Code:
A
Abstract:

To more accurately adjust gripping force in a transmission transmitting power while gripping an annular transmission member by two conical members.

In the transmission having an input cone 34 connected to an input shaft 32 and an output cone 36 connected to an output cone 38 arranged in parallel in mutually opposite direction and gripping a ring 60 by both cones with torque acting on the output shaft 38 by a gripping force adjusting mechanism 50, a shim 70 for setting preload of the gripping force acting on the ring 60 by the gripping force adjusting mechanism 50 is provided on the output shaft 38. Consequently, a preload acting on the ring 60 can be adjusted to an appropriate value only by selecting appropriate ones from a plurality of shims having different height even if manufacturing tolerance and assembly tolerance exist in members constructing a power transmission 20. As a result, accuracy of gripping pressure acting on the ring 60 can be increased.
