Abstract
A torque transmitting mechanism between coaxial first and second rotary parts, at least one of which should be free to move axially relative to the other part, employs two frames at least one of which is resilient. Both frames surround one of the parts (e.g., a shaft for one adjustable pulley of a continuously variable transmission), one of the frames has spaced-apart sections affixed to the first part, and the other frame has spaced-apart sections affixed to the second part (e.g., to one flange of the adjustable pulley). Rivets and/or other suitable fasteners couple the two frames to each other at locations each of which is spaced apart from a section of one of the frames and from a section of the other frame. Each frame can have a polygonal outline with corners which are alternatingly coupled to the other frame and to the respective rotary part. The braces between the corners of each polygonal frame can be profiled to oppose certain types of deformation but to permit other types of deformation.
