Motion Control Speed Reducer

North Babylon, NY – Motion Control Components – Rolling Motion Industries (RMI) is changing the world of mechanical power transmission! New Two Way MAR-17-2-3:1 and the MAR-23-2-3:1 Speed Reducers using Traction Drive Technology leveraged engineering fluids and precision manufacturing with a simple design that features exceptional reliability and up 98% efficiency! 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.


Motion Control Technology –

The propriety engineered traction fluid with a coefficient of friction of just 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. Even though there is no metal-to-metal contact there is no slippage! These compact speed reducers are quiet, generating up to 72% less heat even after weeks of continuous operation, and offer thousands of hours of trouble free operation, as the traction fluid cools and lubricates the traction drive speed reducers. Having low vibration, and no torque losses from 10 to 3000 rpm, these 3:1 2 way speed reducers let motors operate at peak efficiency 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 easily integrated into new and existing applications. Creating 38% lower dB at 3000 rpm than conventional gearboxes these people friendly speed reducers are ideal 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.

About Rolling Motion Industries (RMI)- About Rolling Motion Industries (RMI): In 1993 John Pawloski and his brother Ray took over the family business, Jewelers Machinist Co. They realized they needed to switch from outdated conventional thread grinders to CNC thread grinders. As a result, Jewelers Machinist Co is recognized as the source of some of the most complex thread grinding in the industry. The concept for the RMI traction drive came from John in 2007. Working in that high precision industry aided John in the development of the RMI Traction Drive. In the years that followed, the design of the individual components and formula of the engineered traction fluid were finalized, testing was completed, a patent granted, and production begun. The RMI Traction Drive is one of the most efficient ways to transmit power from one point to another. Utilizing rolling motion, RMI is able to transfer power at various ratios with minimal energy loss. Tested against V-belt, direct drive, chain, and gearbox setups, RMI Traction Drives offer energy saving benefits through true efficiency rating percentages up to 98%. The high efficiency of the traction drive allows electric motors to run at their peak efficiency ranges. There are many applications where it can be used from automotive to industrial to medical. The RMI traction drive can be used in the electric vehicle market and precision applications. Offering benefits such as low backlash and no back driving, it set a new standard for “high efficiency”.
