A. Planetary Epicyclic Drives – Type SA

Employing the latest generation of Rotomission ® technology, this versatile and compact shaft-mounted gearbox can be used as a differential, reducer, or increaser. Differential applications include balance speed and torque, tension control by precise speed adjustment, automatic 2-speed, and position (register) control. The SA product range consists of 10 standard sizes with torque capacities from 2 lb. ft. to 208,000 lb. ft. and reduction ratios between 2:1 and 260:1.

B. Differential Phase-Shifters

The DLO and DR series of differential phase shift-ers allow precise angular adjustment of the output shaft, relative to the input shaft, while the machine IS AT REST OR IN MOTION &IVE SIZES AND five models including DLO (inline) and DR (Right Angle) with ratios of 1:1, 1.5:1, 2:1 and 3:1 make up the standard product line. These precision units have extremely low backlash, minimum transmission error, accept input speeds up to 3000 rpm, and can deliver outpu UP TO LB FT

C. Narrow Band Speed-Control Differentials

The DLA line of differential transmissions ensure excellent speed, draw or tension control by providing a narrow band of variable output speed TO OF INPUT SPEED WHILE AT THE SAME time ensuring that any speed set within this band will hold nearly as well as fixed gearing (i.e. less THAN DEVIATION 4HEREFORE THE $,! provides the accurate speed setting and precise speed holding required to ensure web or strip tension control.

Three standard sizes can offer maximum torque capacity in minimum space, up to 12,400 Lb. In. This closed loop mechanical system, including the variator, typically drives infeeds, chill stands or folder draw rolls in the printing industry. It is also possible to replace the mechanical variator with a variable speed electric motor.
