Atlanta High-Performance (HP) Servo Reducers

This standard range of Servo-Worm Reducers are perfect for use in applications that demand high performance, precise positioning and repeatability. They were specifically developed for use with state-of-the-art servo motor technology, providing tight integration of the motor to the unit. Angular backlash of less than 2 arc-minutes is provided standard, with lower backlash levels available as an option.

They are available in five sizes (50 mm to 125 mm center distance) with input speeds up to 5,000 rpm, reduction ratios from 4.75 to 52:1 and output torque capacities up to 2200Nm. A wide range of motor couplings and mounting flanges are available for assembly to virtually all servo motors, and the hollow bore output can be used to mount output shafts, pinion shafts, or other drive elements.

Typical applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives, zero-backlash axis drives and electronic line shafting. Industries served include Material Handling, Automation, Aerospace, Machine Tool and Robotics.

The following are typical features of our HP-Servo Gear Units:

Backlash: <2 arcmin, adjustable
5 sizes: centre distance 50, 63, 80, 100 and 125mm
8 ratios: 4.75; 6.75; 9.25; 14.5; 19.5; 29; 39; 50 and 52:1
Output torque: from 60 to 2200 Nm
Output hollow shaft:
- key connection
- clamp connection
generously dimensioned and supported for high additional forces
Very high rigidity
Very high precision
ATEX design available

Gearing: Internal gear design was optimized to provide an angular backlash of less than 2 arc-minutes at assembly, with the option of “in the field” adjustable backlash if necessary.

Bearings: Input angular contact bearings for high input speed, and robust output tapered-roller bearings for high radial and axial load capacity.

Housing: Light weight aluminum housing for good heat dissipation, with integral input flange for servo motors and universal mounting on any face.

Output: The output bore is available with a keyway or a compression-type hub (see dimension pages). We offer a line of accessories to adapt this output to straight shafting, Rack & Pinions, or other gearing types.
