Seven pairs of helical gears with splined hubs allowing 25 speed ratios from 0.333 to 3.0. All gears mesh. Use one left hand twist and one right hand twist gear for parallel shafts. Use two gears of the same twist for right angle shafts.

The outside diameters are accurate for gears of 10 diametral pitch. Tooth clearance, root diameter, splines and undercut (for the smaller gears) are not accurate.

Since the splines are not accurate, matching splined shafts and snap rings have been included with the gears.

File set up for 1920 x 1200 cycles render.

    This file seems to work for others. I suggest navigating to the "Help" section and trying some of the suggestions therein. If that doesn't help, contact the site administrators.
