We has over 30 years’ experience with reduction gearbox design and manufacturing. Our dependable, high performance power transfer solutions can be found in numerous sizes and configurations, with torque ratings up to 420Nm to meet our customers’ requirements. Our flange equipment reducers are well suited for a broad spectral range of applications.
Our NEMA gearboxes are designed in compact frames and offer at output that’s 90° from the insight. Along with reduction ratios from 5:1 to 120:1 and optional solitary- and double-result shafts, worm gear styles are versatile enough for several applications. Durable light weight aluminum and steel components make these worm reduction gearboxes perfect for harsh working conditions.

We offers worm gear designs in a variety of torque ideals and with various insight/output sizes to match your requirements. Like all our gearboxes, these units are manufactured for low backlash (≤30 arc mins 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 as far as performance, smooth running and flexibility are concerned. A suitable solution exists for any specified torsional backlash greater than 2 arcmin. Characteristics such as for example maximum economy in all axes, maximum torque density and constant, 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 maximum economy within a lifespan of more than 20,000 hours.
Worm gears are usually used when large rate reductions are needed. The decrease ratio is determined by the number of starts of the worm and number of teeth on the worm equipment. But worm gears possess sliding contact which is calm but will produce heat and also have relatively low transmission efficiency.

For the materials for low backlash worm reducer production, in general, worm is made from hard metal as the worm gear is manufactured out of relatively soft steel such as for example aluminum bronze. That is because the number of tooth on the worm gear is relatively high compared to worm using its number of begins being usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm the teeth is reduced. Another characteristic of worm manufacturing is the need of specific machine for gear reducing and tooth grinding of worms. The worm equipment, on the other hand, may be made with the hobbing machine used for spur gears. But because of the various tooth shape, it isn’t possible to cut many gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
