We has over 30 years’ experience with decrease gearbox design and production. 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 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-result shafts, worm gear styles are versatile enough for several applications. Durable 
aluminium and steel materials 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 fit your requirements. Like all our gearboxes, these units are engineered 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 new servo worm gearbox series from WITTENSTEIN alpha leaves absolutely nothing to be desired as far as performance, smooth operating and versatility are concerned. The right solution exists for any specified torsional backlash higher than 2 arcmin. Characteristics such as for example maximum economy in all 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 give 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 optimum economy within a lifespan greater 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 amount of teeth on the worm equipment. But worm gears have sliding get in touch with which is noiseless but will produce heat and also have relatively low transmission effectiveness.
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 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 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 specific machine for gear slicing 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 several gears at once by low backlash worm reducer stacking the gear blanks as can be done with spur gears.
