Variable speed drives manufactured by Zero-Max are now available with output speeds infinitely adjustable from 0 to 400 rpm, input speeds from 0 to 2000 rpm and constant output torque
An extended range of compact variable speed drives and floating shaft drives supplied by Robert Cupitt is providing further versatility in application and installation for OEM machine and automated assembly line building.
Variable speed drives manufactured by Zero-Max are now available with output speeds infinitely adjustable from 0 to 400 rpm, input speeds from 0 to 2000 rpm and constant output torque throughout the speed range.
Output speed is regulated precisely and easily with a control mechanism that holds speed at the desired setting under full rated load in clockwise, anti-clockwise or either direction.
Designed to be used as primary or secondary drives the units are compact, easily mounted in any position on the machine with no wiring required, and factory sealed/lubricated for reliable and economical performance.
The unique Tol-O-Matic 'Float-a-Shaft' drive maintains perfect alignment when the distances between take-ups are varied during machine operation.
The 'float' enables the shafts to slide axially whilst maintaining drive, or provide for adjustment with minimal downtime - unlike exposed chain sprocket drives that require additional adjustment.
The easily installed one-piece assembly eliminates the need for additional couplings.
Together with a range of brakes, clutches and Crown right-angle gear drives, the variable speed and floating shaft drives provide a complete and versatile system for control of power transmission in a wide range of machines and automated assembly lines.
