| Abstract: |
A marine drive is shown in which a reverse pinion, which is in continuous mesh with a bull gear, is provided with a detuner to prevent vibration while it idles. The detuner includes a ring gear detuner pinion disposed about the reverse pinion shaft. The detuner pinion has helical teeth as do the reverse pinion and bull gear. One end of the detuner pinion is slidably mounted on a ring which encircles the reverse pinion shaft adjacent the reverse pinion, and the other end of the detuner pinion is supported by a diaphragm assembly which prevents torsional and radial motion but permits axial movement of the detuner pinion. The diaphragm assembly is mounted on a sleeve which is secured to the pinion shaft and extends through, but out of contact with, the detuner pinion.

I claim:
1. A detuner for a gear drive including a helical driven gear and a helical pinion which idles in mesh with the driven gear, comprising:
- a detuner pinion having helical teeth in mesh with the driven gear and disposed at one end of said helical pinion;
- a ring coaxial with said helical pinion and supporting the end of said detuner pinion adjacent said helical pinion; and
- a diaphragm assembly including two thin wall diaphragm discs disposed transverse to the axis of the helical pinion and being joined together adjacent their outer perimeters, one of said discs being operatively connected to said helical pinion and the other disc being connected to the other end of said detuner pinion to support such other end.
