This
standard range of Servo-Worm Reducers are perfect for use in
applications that demand good performance, 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 6 arc-minutes is provided standard.
They are available in four sizes (32 mm to
80 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 310 lb.ft.
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 and electronic line shafting.
Industries served include Material Handling, Automation, Aerospace, Machine Tool and
Robotics.

Unit
Design & Construction |
Gearing: Internal gear design was optimized to provide an
angular backlash of less than 6 arc-minutes.
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.

These reducers are typically selected based on the peak cycle forces, which
usually happen during accelerations and decelerations. These cycle
forces depend on the driven load, the speed vs. time profile for
the cycle, and any other external
forces acting on the axis. For more selection information,
please follow this link.
For
application & selection assistance, please call, fax or email us. Your application
information will be reviewed by our engineers, who will recommend the best
solution for your application.
The following
table gives the output torque ratings (in lb.ft.) for the Economy (E) Servo Worm
Reducers at various input speeds and ratios. Service factors need to be
applied to these ratings to make a proper selection.

Ratings are based on servo operation and 12,000 hours running at rated
torque. For continuous operation, please consult the factory. Peak torque values are based
on the ultimate strength of the gearing. Information is subject to change
without notice.
