TRANSFER RING AND GEAR ARRANGEMENT FOR NON-SLIP CONTINUOUSLY VARIABLE TRANSMISSION

摘要

A continuously variable transmission (10) having input (12) and output (14) gearsets each having a pair of bevelled gears (16) rotatable about generally coplanar respective axes of rotation (22) and with the two bevelled faces (24) in a spaced-apart parallel relationship. The input (12) and output (14) gearsets are mounted opposite one another with the bevelled faces (24) aligned. A restorably deformable transfer ring is mounted between the input and output gearsets and a portion of the transfer ring (28) is captured between opposed teeth (24) of the bevelled gears (16). The transfer ring (28) is laterally moveable relative to the input (12) and output (14) gearsets. Rotation of the bevelled gears (16) of the input gearsets (12) deforms a transfer ring (28) and causes the transfer ring (28) to rotate about the transfer ring axis (42) and in turn impart motion to the bevelled gears (16) of the output gearset (14) in an amount determined by the relative lateral position of the transfer ring (28) and the input (12) and output (14) gearsets.
