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.

Why Choose a Dynabox Servo Gearhead?

For simply two reasons: price and performance. Many engineers shy away from right angle designs because of the typical high cost. Two stage bevel planetary configurations can get expensive.

The Dynabox Basic servo worm can achieve up to 90:1 in a single stage and can be provided with several output options for more design versatility. This gives you back the space you need for a much lower cost.

And for super low backlash? The Dynabox Expert is perfect for quiet, precise rotary motion, limiting gear play to less than 1 arc minute.
