Rolling Motion Industries (RMI) has released two high-efficiency traction drives — the MAR-17-1-2.1 Traction Drive and the MAR-23-1-2.1 Traction Drive. These are 1-Way traction drives with only six moving parts and use an engineered traction fluid with a coefficient of friction of just 0.1 to 0.12. These traction drives typically last three times longer than […]
How does a fixed-ratio traction drive work — and potentially outperform gear reducers?
Traction drives have been used for power transmission for more than a century. Now today’s advanced manufacturing and materials have made an innovative new traction drive possible. How traction in general works — and how the new traction drive works Much like the wheels of train cars, traction drives use normal force to generate usable […]
