Eaton expands Airflex clutch line with “world’s largest clutch”
Eaton Corp. – a power management company – announced it has expanded its Airflex clutch line with “the world’s largest clutch for the mineral processing industry,” said Eaton.
The new Airflex 76VC2000 dual clutch system “transmits rotary torque from high-speed electric motors that drive gearboxes or low-speed synchronous motors to high-performing mils up to 14, 750 house power per pinion,” said Eaton. The clutch has a 76-inch diameter friction drum and a new motion-control solution for high- and low-speed motors to “keep component wear to a minimum and reduce power consumption.”
“High-speed motors using gearboxes or low-speed synchronous motors have been available for grinding mills, but mismatched clutches resulted in a start-up rate that was too fast, causing increased stresses on mechanical systems, said Don Keck, Airflex global market development manager in mining. “Eaton’s new VC clutch will enable low-speed synchronous motors or high-speed motors driving through a gearbox to achieve full engagement at a slower rate not achievable with previous clutch solutions, thereby protecting the power train by slowing the acceleration of the entire drive system.”
The VC clutches performed 500,000 cycles in field testing or 50 years of operation. They are custom build for specific requirements available in 24 sizes.
