We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, powerful power transfer solutions are available in many sizes and configurations, with torque rankings up to 420Nm to meet up our clients’ requirements. Our flange equipment reducers are well suited for a broad spectral range of applications.
Our NEMA gearboxes are built in small frames and provide at output that is 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional one- and double-result shafts, worm gear designs are versatile enough for a wide array of applications. Durable aluminium and steel components make these worm reduction gearboxes ideal for harsh low backlash worm reducer working conditions.

We offers worm gear designs in a variety of torque values and with various insight/output sizes to fit your requirements. Like all our gearboxes, these models are manufactured for low backlash (≤30 arc minutes backlash or much less) and high efficiency (up to 90% at 1,000 RPM).
With its three item variants, the new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired as far as performance, smooth operating and flexibility are concerned. The right solution exists for any specific torsional backlash higher than 2 arcmin. Characteristics such as for example maximum economy in all axes, maximum torque density and continuous, low torsional backlash through the entire 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 along with optimal reliability and optimum economy within a lifespan greater than 20,000 hours.
Worm gears are usually used when large acceleration reductions are needed. The decrease ratio depends upon the number of begins of the worm and number of teeth on the worm gear. But worm gears possess sliding contact which is silent but tends to produce heat and also have relatively low transmission effectiveness.

As for the materials for production, in general, worm is constructed of hard metal as the worm gear is made from relatively soft metal such as aluminum bronze. That is because the number of teeth on the worm gear is relatively high in comparison to worm with its number of starts being generally 1 to 4, by reducing the worm gear hardness, the friction on the worm teeth is reduced. Another feature of worm manufacturing may be 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 used for spur gears. But due to the various tooth shape, it isn’t possible to cut many gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
