May 14, 2019 - Rolling Motion Industries (RMI) introduced Two Way MAR-17-2-3:1 and the MAR-23-2-3:1 Speed Reducers using Traction Drive Technology. The MAR17-2-3:1 Speed Reducer is designed for input speeds up to 3600 rpm with 10 to 20 in/lbs of torque, and the MAR-23-2-3:1 Speed Reducer is also rated for speeds to 3600 rpm but with an input of 20 to 30 in/lbs of torque.
The propriety engineered traction fluid with a coefficient of friction of 0.1 to 0.12 transmits torque between the four driving and driven elements. The traction fluid continuously changes from liquid-to-solid-to-liquid in the microscopic spaces between the driving and driven elements.
Having no torque losses from 10 to 3000 rpm, these 3:1 2-way speed reducers let motors operate while having a damping effect on a motor's torque ripple. The speed reducers are available with an optional overriding clutch to protect the components as they can not be back driven. Incorporating standard NEMA mounting dimensions, they can be integrated into new and existing applications.
These speed reducers are designed for use in medical equipment such as mobile hospital equipment and dialysis machines as well as pumps, blowers, fans, turbo and super chargers, conveyers, HVAC systems, and other power transmission and motion applications.
