It's Alive!
by Clive Thompson, Issue 15.01 January 2007

Excerpt: In February 2006, the designers hit another wall. Pleo was too loud, indicating that the gears weren't meshing perfectly and thus were wasting energy. That would be fatal for battery life; they wanted Pleo to go several hours before needing a recharge. (Aibo lasts only an hour and a half.)

Ugobe hired Kleiss Gears, a gearing specialist. Using sophisticated computer modeling to analyze how much force each individual gear exerts on its neighbor, then tweaking the shape of the next gear to optimize the interaction, the firm overhauled Pleo's system. "It grew the gears," Chung says.

When Kleiss handed back the redesigned gears, some of them looked so weird – more like petaled daisies than sharp-toothed mechanical parts – Chung wondered whether they would work. But once installed, they ran in nearly perfect silence.

New Opportunities with Molded Gears
by R.E. Kleiss, A.L. Kapelevich and N.J. Kleiss Jr., Kleiss Gears, Inc.
Molded gearing includes plastic and powder metal injection molded gears as well as powder metal sintered gears. Near-net forged gears may also share some unique similarities and opportunities as well. This type of manufacturing offers some particularly intriguing opportunities for the gear designer, and also some challenges not usually encountered with cut gears.

The challenges are often related to the mechanical properties of the material. Proper steel, cut and hardened correctly, is hard to beat for strength. Ordinary attempts to replace steel gears with the molded variety are usually doomed to failure. [Download PDF]
