Precision Servo-Reducers

Precision Planetary Gearheads
Andantex is pleased to introduce their new line of precision planetary gearheads, for use in a wide variety of industries, including Aerospace, Machine Tool, Automation and Robotics.  Their robust design is torsionally stiff, with large diameter output shafts including integral planet carrier.  They utilize case-hardened gears, finish ground to AGMA 12-14 quality level, to ensure endurance and smooth, quiet power transmission.  Backlash levels down to 1 arc-minute can be provided for the full rated life of the gearhead.  Seven sizes are available, with torque capacities up to 1,250 lb.ft., and ratios from 3:1 to 10:1 in a single stage; 16:1 to 100:1 in two stages, and 125:1 to 175:1 in three stages.

Servo-Worm Reducers
This line of servo-reducers was specifically developed for use with the latest AC & DC servo motor technology. To reach the high level of precision that servo systems demand, the worm & wheel gear designs were improved by increasing their quality levels and optimizing their tooth profiles for minimum backlash.  These units are available in 5 sizes (center distance 50 mm to 125 mm) with ratios from 4.75 to 52:1. and output torque capacities to 1,650 lb.ft.

Corbac "Correctable Backlash" Servo-Reducers
This line of servo-reducers meet all servo-drive requirements: minimum backlash, low input inertia, high torsional stiffness, precise repeatability, and reduction ratios from 12:1 to 100:1 in a compact package. Backlash correction insures that the original backlash value of the reducer can be maintained for the life of the unit. These reducers use unique cycloidal kinematics to achieve their reduction ratios. The units are available in 5 standard sizes and 2 custom sizes with torque capacities up to 7,400 lb.ft.

Z-Series Spiral-Bevel Gearboxes
The new Z-Series Precision Spiral-Bevel Gearbox range can be adapted with a servo-flange to accommodate the latest servo motor technology.  Available in 7 sizes & 6 model types, they feature high-quality, case-hardened & lapped alloy steel spiral-bevel gears, cut by the Klingelnberg method.  This high quality level insures low noise, backlash, and transmission error.   Ratios from 0.5 to 6:1 are available, with input speeds up to 5,500 rpm.
