We has over 30 years’ experience with decrease low backlash worm reducer gearbox design and manufacturing. Our dependable, powerful power transfer solutions can be found in several 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 offer at output that’s 90° from the input. Along with decrease ratios from 5:1 to 120:1 and optional one- and double-result shafts, worm gear styles are versatile enough for a wide array of applications. Durable aluminium and steel materials make these worm reduction gearboxes perfect for harsh working conditions.

We offers worm equipment designs in a variety of torque values and with various insight/output sizes to fit your requirements. Like all our gearboxes, these units are manufactured for low backlash (≤30 arc 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 flexibility are concerned. The right solution exists for any specific torsional backlash greater than 2 arcmin. Features such as for example maximum economy in all axes, optimum torque density and constant, low torsional backlash through the entire 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 number 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 swiftness reductions are needed. The decrease ratio depends upon the number of starts of the worm and amount of tooth on the worm gear. But worm gears possess sliding get in touch with which is quiet but will produce heat and also have relatively low transmission efficiency.

As for the materials for creation, in general, worm is constructed of hard metal as the worm gear is manufactured out of relatively soft metal such as aluminum bronze. This is because the number of tooth on the worm equipment is relatively high compared to worm with its number of begins being usually 1 to 4, by reducing the worm gear hardness, the friction on the worm tooth is reduced. Another characteristic of worm manufacturing may be the need of specialized machine for gear reducing and tooth grinding of worms. The worm gear, however, may be made out of the hobbing machine used for spur gears. But because of the various tooth shape, it is not possible to cut a number of gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
