We has over 30 years’ experience with reduction gearbox design and manufacturing. Our dependable, powerful power transfer solutions can be found in numerous sizes and configurations, with torque ratings up to 420Nm to meet up our customers’ requirements. Our flange equipment reducers are well suited for a broad spectral range 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 single- and double-result shafts, worm gear designs are versatile enough for several applications. Durable aluminium and steel components make these worm decrease gearboxes well suited for harsh working conditions.

We offers worm equipment designs in a range of torque ideals and with various insight/output sizes to fit your requirements. Like all our gearboxes, these devices are manufactured 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 new servo worm gearbox series from WITTENSTEIN alpha leaves absolutely nothing to be desired as far as performance, smooth operating and flexibility are concerned. A suitable solution exists for just about any specified torsional backlash higher than 2 arcmin. Characteristics such as for example maximum economy in every axes, maximum torque density and continuous, low torsional backlash low backlash worm reducer through the entire service life are common to all or any of the gearboxes.
these servo worm gearboxes give you best-in-class precision – tailored precision up to ≤ 2 arcminutes for a number of applications. You benefit from rapid availability in addition to optimal reliability and maximum economy within a lifespan of more than 20,000 hours.
Worm gears are usually used when large speed reductions are needed. The decrease ratio depends upon the number of starts of the worm and quantity of teeth on the worm equipment. But worm gears possess sliding get in touch with which is calm but will produce heat and have relatively low transmission effectiveness.

For the materials for production, in general, worm is made of hard metal as the worm gear is made from relatively soft metallic such as for example aluminum bronze. That is since the number of the teeth on the worm gear is relatively high in comparison to worm using its number of begins being generally 1 to 4, by reducing the worm equipment hardness, the friction on the worm tooth is reduced. Another feature of worm manufacturing is the need of specialized machine for gear reducing and tooth grinding of worms. The worm equipment, however, may be made with the hobbing machine used for spur gears. But because of the different tooth shape, it is not possible to cut several gears simultaneously by stacking the gear blanks as can be carried out with spur gears.
