North Babylon, NY – Rolling Motion Industries (RMI) has released for production the next two in it’s series of highly efficient speed reducers. These 3-to-1 speed reducers use “game changing” traction drive technology. The MAR-17-1-3.1 and the MAR-23-1-3.1 Speed Reducers feature 98% efficiency and with only 6 moving parts they typically out last conventional gearboxes and speed reducers by a factor of 3. 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 just 0.1 to 0.12 that cools and lubricates the traction drive these high efficiency speed reducers generate up to 72% less heat even 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. 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.

Having low vibration, and no torque losses from 10 to 3000 rpm, these speed reducers featuring traction drive technology lets a motor operate at peak efficiency while having a damping effect on a motor’s torque ripple. These revolutionary speed reducers are available with an optional overriding clutch. Incorporating standard NEMA mounting dimensions, these speed reducers can be easily integrated into new and existing 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and his brother Ray took over the family business, Jewelers Machinist Co. They realized they needed to switch from outdated conventional thread grinders to CNC thread grinders.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”.

Traction Drive Technology

From RMI (Rolling Motion Industries ):

We offer a new patented technology that is going to be a game changer in many industries. Traction drives have been around for over 100 years, but they were complex and expensive. What we offer is simple and cost-effective. Our technology gives smooth, quiet, efficient and accurate rotation. These offerings solve current problems in the industry, and RMI is the solution. With the use of the most modern CNC equipment and precise tooling at our partner/manufacturer FCS, we can handle any quantity, any size drive, and any application.

Due to the simplistic design of our patented product we are able to penetrate many markets. In most circumstances, a superior product means a much more expensive product, but this is not the case with RMI. Simplicity is the essence of brilliance is a saying and our patented technology sure fits that category. RMI started as a visualization of a new way to get to point B.

This new traction drive from Rolling Motion Industries called the RMI Marmalade includes six moving parts — a cup shaft component, a toroidal shaft component, twin precision-matched bearings for shaft support, one pair of rolling elements between the shaft elements, and engineered traction fluid to help the balls transmit torque. The engineered traction fluid inside the sealed housing works for power transmission and cools and lubricates the drive. A microscopic gap between the rolling elements lets the fluid slip through — but as the fluid squeezes through this microscopic gap, high pressure causes the fluid to temporarily solidify. Then the solid structure of the fluid transmits torque from input to output shaft. Material science has enabled this new traction drive mode of operation. Traditional traction-drive fluids have friction coefficients of 0.05 to 0.06. The new drive employs fluid with coefficients of friction of 0.1 to 0.12 — particularly useful for the transfer of torque through smaller normal forces … even with operation that makes slippage between input and output shafts impossible.

Advanced Manufacturing and Materials Have Made an Innovative, Highly Efficient Traction Drive Possible!

 

RMI Drives-Logo

North Babylon, NY – 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 conventional gearboxes and with no metal to metal contact these high efficiency drives generate up to 72% less heat after 24 hours of continuous operation, Additionally they create up to 38% lower dB at 3000 rpm (less than a home refrigerator) than conventional gearboxes. Even though there is no metal to metal contact there is no slippage or lost motion between the input and output shafts.

The MAR17-1-2.1 Traction Drive is designed for speeds to 3600 rpm with 10 to 20 in/lbs of torque, and the MAR-23-1-2.1 Traction Drive is rated for 3600 rpm with 20 to 30 in/lbs of torque. Operating at temperatures that are lower than a motor’s, with low vibration, and no torque losses from 10 to 3000 rpm, these traction drives permit a motor to operate at peak efficiency. Applications for these 1-Way traction drives which can operate in explosive environments (ie. zone 1 and 21) include: Pumps, blowers, fans, turbo and super chargers, conveyers, HVAC systems, medical applications, and other power transmission and motion applications.

These revolutionary drives are available with an optional overriding clutch. Incorporating standard NEMA mounting dimensions, these drives can be easily integrated into new and existing applications.
