We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, high performance power transfer solutions are available in several 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 low backlash planetary gearbox gearboxes are built in compact frames and provide at output that’s 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional single- and double-output shafts, worm gear styles 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 match your requirements. Like all our gearboxes, these models are manufactured for low backlash (≤30 arc a few minutes backlash or less) and high efficiency (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 as far as performance, smooth running and versatility are concerned. A suitable solution exists for any specific torsional backlash greater than 2 arcmin. Features such as for example maximum economy in every axes, optimum torque density and continuous, low torsional backlash through the entire service life are normal to all or any 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 within a lifespan of more than 20,000 hours.
Worm gears are often used when large rate reductions are needed. The reduction ratio is determined by the number of begins of the worm and number of the teeth on the worm equipment. But worm gears have sliding contact which is tranquil but will produce heat and also have relatively low transmission performance.

As for the materials for creation, in general, worm is made from hard metal while the worm gear is manufactured out of relatively soft metal such as aluminum bronze. That is because the number of tooth on the worm equipment is relatively high compared to worm with its number of begins being generally 1 to 4, by reducing the worm gear hardness, the friction on the worm tooth is reduced. Another characteristic of worm manufacturing is the need of specific machine for gear cutting and tooth grinding of worms. The worm equipment, however, may be made with the hobbing machine utilized for spur gears. But because of the different tooth shape, it isn’t possible to cut several gears simultaneously by stacking the gear blanks as can be carried out with spur gears.
