Speed-o-Cam

 

United States Patent, No. US 6,382,0382 (download image files)   An innovative speed reducer intended to replace gears and harmonic drives.

Advantages:

• Low friction
• Low backlash
• High stiffness
• Manufacturable with general-purpose CNC machine tools

Three versions:

• Planar, to couple parallel shafts
• Spherical, to couple intersecting shafts
• Convex planar, for higher machinability
