Dynabox - Precision Right Angle Servo Worm Reducers

Girard's right angle worm reducers provide precise rotary motion for highly dynamic cyclical or speed control servo applications. Available in 3 backlash levels to satisfy a variety of applications. Output options include single and dual shafts, hollow bore with keyway, hollow bore with shrink disc, and rotary output flanges.

Features & Benefits:

Low Backlash: Three levels of backlash from 10 arc minutes to less than 1 arc minute assures the proper repeatability for your application.
Multiple Output Options: Available in single or double output shafts, hollow bore with keyway, hollow bore with shrink disc, and rotary output flanges.
Universal Motor Mounting: Provided with an adapter for virtually all servo motors and a torsionally rigid flexible coupling for optimum motor shaft alignment.
Optimized Gearing: Hardened and ground worms and bronze alloy wheels provide high torque, smooth operation, and superior shock absorption.
Higher Radial Load Capacity: Oversized taper roller bearings accommodate high radial forces.
Lower Noise: Precision worm gearing provides noise levels below 55dB.
Aluminum Alloy Housings: A hardened aliminum-magnesium alloy housing results in lower weight and higher torsional rigidity. XL series is cast iron for high strength.
Constant Worm Bearing Preload: A unique 3 bearing arrangement maintains proper worm bearing preload over all allowable temperature ranges.
Gearhead Mounting Options: Tapped holes, through holes, and centering flanges maximizes gearhead integration.
