Rolling Motion Industries (RMI) releases MAR-17-1-3.1 and the MAR-23-1-3.1 Speed Reducers

January 17, 2019 - Rolling Motion Industries (RMI) has released for production the next two in it's series of speed reducers.  These 3-to-1 speed reducers use traction drive technology. The MAR-17-1-3.1 and the MAR-23-1-3.1 Speed Reducers feature 98% efficiency and with 6 moving parts. The MAR17-1-3.1 Speed Reducer  is designed for input speeds up to 3600 rpm with 10 to 20 in/lbs of torque, and the MAR-23-1-3.1 Speed Reducer is also rated for speeds to 3600 rpm but with an input of 20 to 30 in/lbs of torque.  As the output speed is reduced by a factor of 3 the output torque increases by a factor of 3.

Using an engineered traction fluid with a coefficient of friction of 0.1 to 0.12 that cools and lubricates the traction drive these speed reducers generate up to 72% less heat after days of continuous operation.  There is no slippage or lost motion between the input and output shafts even though there is no metal to metal contact as the traction fluid is continuously changing from liquid-to-solid-to-liquid as the driving and driven elements interface in the drive.  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.
