We has over 30 years’ experience with decrease gearbox design and production. Our dependable, powerful power transfer solutions can be found in several sizes and configurations, with torque low backlash worm reducer rankings up to 420Nm to meet up our customers’ requirements. Our flange equipment reducers are well suited 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-result shafts, worm gear styles are versatile enough for a wide array of applications. Durable light weight aluminum and steel components make these worm reduction gearboxes ideal for harsh working conditions.

We offers worm gear designs in a variety of torque ideals and with various input/output sizes to fit your requirements. Like all our gearboxes, these units are engineered for low backlash (≤30 arc minutes backlash or less) and high performance (up to 90% at 1,000 RPM).
With its three item variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired so far as performance, smooth working and flexibility are concerned. A suitable solution exists for any specific torsional backlash greater than 2 arcmin. Features such as for example maximum economy in all axes, optimum torque density and constant, low torsional backlash throughout the service life are normal to all of the gearboxes.
these servo worm gearboxes give you best-in-course precision – tailored precision up to ≤ 2 arcminutes for a number of applications. You profit from rapid availability in addition to optimal reliability and optimum economy throughout a lifespan greater than 20,000 hours.
Worm gears are often used when large speed reductions are needed. The decrease ratio is determined by the number of begins of the worm and amount of tooth on the worm equipment. But worm gears have sliding contact which is peaceful but tends to produce heat and also have relatively low transmission efficiency.

As for the materials for creation, in general, worm is constructed of hard metal as the worm gear is made from relatively soft steel such as for example aluminum bronze. This is since the number of the teeth on the worm equipment is relatively high in comparison to worm with its number of starts being generally 1 to 4, by reducing the worm equipment hardness, the friction on the worm teeth is reduced. Another feature of worm manufacturing is the need of specific machine for gear cutting and tooth grinding of worms. The worm equipment, however, may be made out of the hobbing machine utilized for spur gears. But because of the various tooth shape, it isn’t possible to cut several gears simultaneously by stacking the gear blanks as can be done with spur gears.
