ABSTRACT:
A power take-off unit for a transaxle is provided with a unique double enveloping worm/worm gear transmission which has a ratio of the number of gear teeth on the worm gear to the number of threads on the worm which is low. The worm/worm gear transmission is more compact than conventional bevel gear systems which have typically been used in power take-off unit applications. The worm and worm gear transmission of the present invention also is quieter in operation and has a higher torque capacity than standard bevel gears of comparable size.
