We has over 30 years’ experience with reduction gearbox design and manufacturing. Our dependable, high performance power transfer solutions can be found in many sizes and configurations, with torque rankings up to 420Nm to meet our customers’ requirements. Our flange gear reducers are perfect for a broad spectrum of applications.
Our NEMA gearboxes are built in compact frames and provide at output that is 90° from the input. Along with decrease ratios from 5:1 to 120:1 and optional one- and double-output shafts, worm gear designs are versatile enough for several applications. Durable aluminum and steel components make these worm reduction gearboxes well suited for harsh working conditions.

We offers worm gear designs in a variety of torque values and with various input/output sizes to fit your requirements. Like all our gearboxes, these devices are designed for low backlash (≤30 arc moments backlash or much less) and high effectiveness (up to 90% at 1,000 RPM).
With its three product variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves absolutely nothing to be desired so far as performance, low backlash worm reducer smooth working and versatility are concerned. The right solution exists for just about any specified torsional backlash higher than 2 arcmin. Characteristics such as 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 offer you best-in-class precision – tailored precision up to ≤ 2 arcminutes for a variety of applications. You benefit from rapid availability along with 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 decrease ratio is determined by the number of starts of the worm and number of tooth 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 creation, in general, worm is constructed of hard metal while the worm gear is made from relatively soft steel such as aluminum bronze. That is because the number of the 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 gear hardness, the friction on the worm teeth is reduced. Another feature of worm manufacturing is the need of specific machine for gear slicing and tooth grinding of worms. The worm equipment, however, may be made with the hobbing machine used for spur gears. But due to the various tooth shape, it isn’t possible to cut several gears at once by stacking the apparatus blanks as can be carried out with spur gears.
