Dual Lead Worm Gearbox
Double Lead Worm Gear Reducer-Flange Output
Precision dual lead worm gear reducer with a positioning accuracy of up to 30 arc seconds, featuring high speed ratio, high torque, smooth transmission, impact resistance, self-locking, and adjustable backlash.
Standard Series – High-Precision Servo Worm Gearbox
(10 sizes with capacities to 2000 Nm)
- 9 exact ratios from 5.2:1 to 90:1
- Housings are made from aluminum-magnesium alloy.
- Two levels of backlash precision: A < 1 arc minute, B < 3 arc minutes
*Support drawings and samples customization
- Low Backlash – 2 levels of backlash from 3 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 with unique dual compound ground gear flanks that deliver 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 55 dB.
- Aluminum Alloy Housings – A hardened aluminum-magnesium alloy housing results in lower weight and higher torsional rigidity.
- Constant Worm Bearing Preload – A unique 3-bearing arrangement on this high-precision gearbox maintains proper worm-bearing preload overall allowable temperature ranges.
- Gearhead Mounting Options – Tapped holes, through holes, and centering flanges maximize gearhead integration.
