High-Performance Servo-Worm Reducers

Overview:

This line of servo-worm reducers was specifically developed for use with the latest servo motor technology in applications that demand precise positioning and repeatability. Typical applications include traveling gantries, horizontal & vertical axis drives, pick & place robots, and replacements for long ball screw axis drives. These applications often occur in the Material Handling, Automation, CNC Machine Tool and Robotics Industries.

These reducers are available in five sizes (center distance 30 mm to 180 mm) with ratios from 2 to 14:1 and output torque capacities to 4,400 lb.ft. The units provide an angular backlash of less than 6 arc-minutes, and the advantage of “in the field” adjustable backlash. The worm & wheel gear designs are optimized for minimum backlash.

Various couplings and mounting flanges are available for assembly with virtually all servo motors. The output shaft of the worm reducer is available with a keyway or a compression-type coupling. We also offer a line of accessories to adapt this output to straight shafting, Rack & Pinions, or other gearing types.

* Ratings are based on servo operation and 12,000 hour life at rated torque.
For continuous operation, thermal limitations must be considered, please consult the factory.
Peak torque values are based on the ultimate strength of the gear teeth and should not be used solely in selecting a unit.
Information provided is subject to change without notice.

** For Size 7, max. input speed for 4.75:1 ratio is 2,200 rpm; max. input speed for 6.75:1 ratio is 2,800 rpm.
