We has over 30 years’ experience with decrease gearbox design and production. Our dependable, powerful power transfer solutions can be found in numerous sizes and configurations, with torque rankings up to 420Nm to meet up our customers’ requirements. Our flange equipment reducers are ideal for a broad spectrum of applications.
Our NEMA gearboxes are designed in small frames and offer at output that is 90° from the insight. Along with reduction ratios from 5:1 to 120:1 and optional single- and double-output shafts, worm gear styles are versatile enough for several applications. Durable aluminum and steel materials make these worm reduction gearboxes well suited for harsh working conditions.

We offers worm equipment low backlash planetary gearbox designs in a variety of torque ideals and with various insight/output sizes to fit your requirements. Like all our gearboxes, these units are designed for low backlash (≤30 arc mins backlash or much less) and high performance (up to 90% at 1,000 RPM).
With its three item variants, the new servo worm gearbox series from WITTENSTEIN alpha leaves absolutely nothing to be desired as far as performance, smooth operating and versatility are concerned. The right solution exists for just about any specified torsional backlash greater than 2 arcmin. Attributes such as maximum economy in all axes, maximum torque density and continuous, low torsional backlash throughout the service life are normal to all or any of the gearboxes.
these servo worm gearboxes offer you best-in-class precision – tailored precision up to ≤ 2 arcminutes for a variety of applications. You profit from rapid availability as well as optimal reliability and optimum economy within a lifespan greater than 20,000 hours.
Worm gears are often used when large velocity reductions are needed. The reduction ratio depends upon the number of starts of the worm and number of tooth on the worm equipment. But worm gears have sliding contact which is quiet but will produce heat and have relatively low transmission performance.

For the materials for creation, in general, worm is made of hard metal as the worm gear is made from relatively soft metal such as for example aluminum bronze. That is since the number of the teeth on the worm equipment is relatively high in comparison to worm with its number of begins being generally 1 to 4, by reducing the worm equipment hardness, the friction on the worm tooth is reduced. Another characteristic of worm manufacturing is the need of specialized machine for gear reducing and tooth grinding of worms. The worm gear, however, may be made with the hobbing machine utilized for spur gears. But due to the various tooth shape, it isn’t possible to cut a number of gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
