The traction reducer is a technique that uses rollers that move together while one roller transfers power to the other. The rollers are forced against each other by a lubricant oil coating. The contact area of each roller experiences intense pressure. Under normal pressure, liquid molecules can move around freely, but under high pressure, they line up regularly and solidify into crystals.
This property of molecules is used by the traction reducer to transfer power from one roller to the other. Traction reducers, in contrast to gears, are extremely silent, can considerably reduce backlash, and are less prone to impact noise created by the meshing force of the gears because the rollers are continually in contact even when the drive is not moving.
Traction reducer can transmit power very smoothly since there are no high-frequency speed fluctuations brought on by gear teeth’s pitch faults (processing accuracy).
The Global traction reducer market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Hicksville, – Stock Drive Products/Sterling Instrument (SDP/SI), a pioneer in mechanical-based design, engineering, and precision manufacture for essential motion control and small power transmission applications, is pleased to announce Speed Reducers with traction drive technology. These speed reducers are extremely efficient and have only 6 moving parts thanks to their gearless drive.
With designed traction fluid, which regularly transitions from liquid to solid to liquid when the driving and driven elements in the drive interface, less heat is produced than with conventional drives.
This revolutionary technology has undergone extensive development and testing over many years, and as a consequence, it offers infinite ratios up to a ratio of 5:1, a sharp reduction in motor torque ripple, low vibration and noise levels, and much lower maintenance costs than a conventional system.
Reducer for NSK EV Traction Drive, The Traction Reducer transmits rotational force through a unique oil that, when compressed, briefly becomes hard. No torque or rotational speed, this enables the drive to operate silently.
It is possible to further reduce the size and weight of electric drive systems by combining this ground-breaking traction reducer with a high speed traction motor.
With the launch of Valvoline EV Performance Fluids, Valvoline, a top global provider of premium branded lubricants and automotive services, launched the first of its electric vehicle-specific product and service solutions today.
These products offer anti-corrosion, churning loss reduction, and electric motor cooling in four formulas to meet the changing needs of multi-speed EV transmissions: EV, a full synthetic; Ultra Low Viscosity, which extends vehicle range and boosts efficiency for multi-speed transmissions; Ultra EV, a thermally stable fluid with superior low-temperature performance; and EV Traction, which is advised for EVs with traction drive systems.
