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.

RMI Drives-Logo

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.

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.

Motion Control – Highly Efficient 2 Way Traction Drives Reduce Motor Torque Ripple up to 84%!

North Babylon, NY – Motion Control Components – Rolling Motion Industries (RMI) has released two new traction drives. The MAR-17-2-2.1 Traction Drive and the MAR-23-2-2.1 Traction Drive. These highly efficient 2-Way gearless traction drives with only six moving parts use an engineered traction fluid with a coefficient of friction of just 0.1 to 0.12. The MAR-17-2-2.1 and MAR-23-2-2.1 Traction Drives have demonstrated an up to 84% reduction in motor torque ripple when measured at the output shaft of the motor and then measures at the output shaft of the traction drive. The MAR17-2-2.1 Traction Drive is designed for speeds to 3600 rpm with 10 to 20 in/lbs of torque, and the MAR-23-2-2.1 Traction Drive is rated for 3600 rpm with 20 to 30 in/lbs of torque.

Having no metal to metal contact these compact, high efficiency drives generate up to 72% less heat after 24 hours of continuous operation, and these permanently lubricated traction drives typically last three times longer than conventional gearboxes, They also create up to 38% lower dB at 3000 rpm than conventional gearboxes which is less than a typical home appliance. Even though there is no metal to metal contact there is no slippage or lost motion between the input and output shafts.

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 2-Way traction drives which can operate in explosive environments (ie. zone 1 and 21) include: Medical (including patient handling), pharmaceuticals, wafer handling, robotics, conveyers, sorting, pumps, assembly, battery operated vehicles, 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.
