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 equipment reducers are perfect for a broad spectral range of applications.
Our NEMA gearboxes are built in compact frames and provide at output that’s 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional solitary- and double-output low backlash planetary gearbox shafts, worm gear styles are versatile enough for a wide array of applications. Durable light weight aluminum and steel materials make these worm reduction gearboxes well suited for harsh working conditions.

We offers worm equipment designs in a variety of torque ideals and with various insight/output sizes to fit your requirements. Like all our gearboxes, these products are manufactured for low backlash (≤30 arc a few 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 so far as performance, smooth working and flexibility are concerned. The right solution exists for any specified torsional backlash higher than 2 arcmin. Features such as maximum economy in every axes, optimum torque density and constant, low torsional backlash throughout the service life are normal to all or any of the gearboxes.
these servo worm gearboxes offer you best-in-course precision – tailored precision up to ≤ 2 arcminutes for a variety of applications. You profit from rapid availability along with optimal reliability and maximum economy within a lifespan of more than 20,000 hours.
Worm gears are often used when large quickness reductions are needed. The reduction ratio depends upon the number of begins of the worm and amount of teeth on the worm gear. But worm gears possess sliding contact which is peaceful but will produce heat and 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 gear is relatively high in comparison to worm using its number of starts being generally 1 to 4, by reducing the worm gear hardness, the friction on the worm the teeth is reduced. Another feature of worm manufacturing is the need of specialized machine for gear slicing and tooth grinding of worms. The worm gear, however, may be made with the hobbing machine used for spur gears. But because of the various tooth shape, it isn’t possible to cut a number of gears simultaneously by stacking the gear blanks as can be done with spur gears.
