We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, powerful power transfer solutions can be found in many sizes and configurations, with torque rankings up to 420Nm to meet up our customers’ requirements. Our flange equipment reducers are ideal for a broad spectrum of applications.
Our NEMA gearboxes are designed in small frames and offer at output that is 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional single- and double-output shafts, worm gear designs are versatile enough for several applications. Durable 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 values and with various insight/output sizes to fit your requirements. Like all our gearboxes, these units are designed for low backlash (≤30 arc minutes backlash or much 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 operating and versatility are concerned. A suitable solution exists for just about any specific torsional backlash higher than 2 arcmin. Characteristics 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 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 benefit from rapid availability in addition to optimal reliability and maximum economy within a lifespan greater than 20,000 hours.
Worm gears are usually used when large rate reductions are needed. The reduction ratio is determined by the number of starts of the worm and amount of teeth on the worm equipment. But worm gears have sliding get in touch with which is tranquil but will produce heat and also have relatively low transmission effectiveness.

As for the materials for production, in general, worm is constructed of hard metal while the worm gear is made from relatively soft metal such as for example aluminum bronze. This is since the number of the teeth on the worm gear is relatively high in comparison to worm with its number of starts being usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm teeth is reduced. Another characteristic of worm low backlash planetary gearbox manufacturing is the need of specific machine for gear slicing and tooth grinding of worms. The worm equipment, on the other hand, may be made out of the hobbing machine utilized for spur gears. But due to the various tooth shape, it is not possible to cut a number of gears simultaneously by stacking the apparatus blanks as can be carried out with spur gears.
