We has over 30 years’ experience with decrease gearbox design and production. Our dependable, powerful power transfer solutions are available in several sizes and configurations, with torque rankings up to 420Nm to meet up our clients’ requirements. Our flange equipment reducers are perfect for a broad spectrum of applications.
Our NEMA gearboxes are designed in small frames and offer at output that’s 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional single- and double-result shafts, worm gear styles are versatile enough for several applications. Durable aluminium and steel components make these worm reduction gearboxes perfect for harsh working conditions.

We offers worm equipment designs in a range of torque values and with various insight/output sizes to fit your requirements. Like all our gearboxes, these models are designed for low backlash (≤30 arc moments backlash or much less) and high performance (up to 90% at 1,000 RPM).
With its three product low backlash worm reducer variants, the new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired so far as performance, smooth working and versatility are concerned. A suitable solution exists for just about 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 throughout the service life are common to all 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 optimum economy throughout a lifespan of more than 20,000 hours.
Worm gears are usually used when large speed reductions are needed. The decrease ratio depends upon the number of begins of the worm and quantity of teeth on the worm gear. But worm gears have sliding contact which is quiet but tends to produce heat and also have relatively low transmission performance.

As for the materials for production, in general, worm is made of hard metal as the worm gear is manufactured out of relatively soft metallic such as for example aluminum bronze. That is because the number of tooth on the worm equipment is relatively high in comparison to worm with its number of starts being generally 1 to 4, by reducing the worm equipment hardness, the friction on the worm tooth is reduced. Another characteristic of worm manufacturing may be the need of specialized machine for gear cutting 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 many gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
