Press Release Summary:
The MAR-17-2-2.1 and MAR-23-2-2.1 Traction Drives use a traction fluid with a coefficient of friction of 0.1 to 0.12. The units are suitable for use in medical, pharmaceuticals, wafer handling, robotics, conveyers and power transmission and motion applications. The MAR-17-2-2.1 and MAR-23-2-2.1 are rated for speed of 3600 rpm with 10 to 20 in/lbs and 20 to 30 in/lbs of torque respectively. They are offered with an optional overriding clutch and permit motor to operate at peak efficiency.
Original Press Release:
Highly Efficient 2 Way Traction Drives Reduce Motor Torque Ripple up to 84%!
North Babylon, NY - 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.
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”.
