We has over 30 years’ experience with decrease gearbox design and production. Our dependable, high performance power transfer solutions are available in several sizes and configurations, with torque rankings up to 420Nm to meet up our clients’ requirements. Our flange gear reducers are perfect for a broad spectral range of applications.
Our NEMA gearboxes are built in small frames and offer at output that is 90° from the input. Along with reduction ratios from 5:1 to 120:1 and low backlash planetary gearbox optional single- and double-output shafts, worm gear designs are versatile enough for several applications. Durable light weight aluminum and steel components make these worm decrease gearboxes well suited for harsh working conditions.

We offers worm gear designs in a range of torque ideals and with various insight/output sizes to fit your requirements. Like all our gearboxes, these products are engineered for low backlash (≤30 arc minutes backlash or less) and high effectiveness (up to 90% at 1,000 RPM).
With its three item variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves absolutely nothing to be desired so far as performance, smooth operating and flexibility are concerned. The right solution exists for just about any specified torsional backlash greater than 2 arcmin. Features such as for example maximum economy in every axes, maximum torque density and continuous, low torsional backlash throughout the service life are common to all of the gearboxes.
these servo worm gearboxes offer you best-in-class precision – tailored precision up to ≤ 2 arcminutes for a number of applications. You benefit from rapid availability and also optimal reliability and optimum economy within a lifespan greater than 20,000 hours.
Worm gears are often used when large rate reductions are needed. The reduction ratio depends upon the number of starts of the worm and number of the teeth on the worm gear. But worm gears possess sliding contact which is calm but will produce heat and also have relatively low transmission effectiveness.

As for the materials for production, in general, worm is made from hard metal as the worm gear is manufactured out of relatively soft metal such as aluminum bronze. That is because the number of the teeth on the worm equipment is relatively high compared to worm using its number of starts 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 gear, however, may be made with the hobbing machine utilized for spur gears. But due to the different 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.
