We has over 30 years’ experience with reduction gearbox design and production. Our dependable, powerful power transfer solutions are available in several sizes and configurations, with torque rankings up to 420Nm to meet our clients’ requirements. Our flange gear reducers are well suited for a broad spectrum of applications.
Our NEMA gearboxes are designed in compact frames and provide at output that is 90° from the insight. Along with reduction ratios from 5:1 to 120:1 and optional one- and double-output shafts, worm gear styles are versatile enough for several applications. Durable light weight aluminum and steel components make these worm reduction gearboxes perfect for harsh working conditions.

We offers worm equipment designs in a range of torque ideals and with various input/output sizes to fit your requirements. Like all our gearboxes, these units are manufactured for low backlash (≤30 arc a few minutes 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 flexibility are concerned. The right solution exists for just about any specific torsional backlash greater than 2 arcmin. Attributes such as for example maximum economy in every axes, optimum torque density and constant, low torsional backlash throughout the service life are normal to all 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 benefit from rapid availability as well as optimal reliability and maximum economy throughout a lifespan of more than 20,000 hours.
Worm gears are often used when large low backlash planetary gearbox swiftness reductions are needed. The decrease ratio is determined by the number of begins of the worm and quantity of the teeth on the worm gear. But worm gears have sliding get in touch with which is peaceful but will produce heat and also have relatively low transmission efficiency.

For the materials for production, in general, worm is made from hard metal while the worm gear is made from relatively soft metal such as aluminum bronze. This is since the number of teeth on the worm gear is relatively high in comparison to worm with its number of starts being usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm tooth is reduced. Another feature of worm manufacturing may be the need of specific machine for gear trimming and tooth grinding of worms. The worm equipment, however, may be made with the hobbing machine utilized for spur gears. But due to the different tooth shape, it is not possible to cut several gears at once by stacking the apparatus blanks as can be carried out with spur gears.
