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 our customers’ requirements. Our flange gear reducers are well suited for a broad spectral range of applications.
Our NEMA gearboxes are designed in small frames and offer at output that’s 90° from the input. Along with decrease ratios from 5:1 to 120:1 and optional single- and double-result shafts, worm gear designs are versatile enough for several applications. Durable light weight aluminum and steel components make these worm decrease gearboxes ideal for harsh working conditions.

We offers worm equipment designs in a variety of torque ideals and with various input/output sizes to match your requirements. Like all our gearboxes, these models are engineered for low backlash (≤30 arc moments backlash or much 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 so far as performance, smooth running 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, maximum torque density and continuous, low torsional backlash throughout the 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 variety of applications. You benefit from rapid availability in addition to optimal reliability and maximum economy low backlash planetary gearbox within a lifespan greater than 20,000 hours.
Worm gears are usually used when large swiftness reductions are needed. The reduction ratio depends upon the number of starts of the worm and quantity of teeth on the worm gear. But worm gears have sliding get in touch with which is silent but will produce heat and have relatively low transmission effectiveness.

For the materials for production, 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 tooth 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 trimming and tooth grinding of worms. The worm equipment, however, may be made out of the hobbing machine used for spur gears. But because of the different tooth shape, it isn’t possible to cut a number of gears at once by stacking the gear blanks as can be carried out with spur gears.
