We has over 30 years’ experience with decrease gearbox design and production. Our dependable, powerful power transfer solutions are available in numerous sizes and configurations, with torque ratings up to 420Nm to meet up our customers’ requirements. Our flange gear reducers are perfect 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 decrease ratios from 5:1 to 120:1 and optional solitary- and double-result shafts, worm gear styles are versatile enough for a wide array of applications. Durable aluminium and steel components make these worm reduction gearboxes perfect for harsh working conditions.
We offers worm equipment designs in a variety of torque values and with various input/output sizes to fit your requirements. Like all our gearboxes, these units are manufactured for low low backlash worm reducer backlash (≤30 arc minutes backlash or much less) and high performance (up to 90% at 1,000 RPM).
With its three product variants, the new servo worm gearbox series from WITTENSTEIN alpha leaves absolutely nothing to be desired so far as performance, smooth running and versatility are concerned. A suitable solution exists for just about any specified torsional backlash higher than 2 
arcmin. Characteristics such as maximum economy in all axes, optimum torque density and constant, low torsional backlash throughout the service life are normal to all of the gearboxes.
these servo worm gearboxes give you best-in-class precision – tailored precision up to ≤ 2 arcminutes for a variety 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 acceleration reductions are needed. The reduction ratio depends upon the number of starts of the worm and number of teeth on the worm gear. But worm gears possess sliding contact which is silent but will produce heat and have relatively low transmission effectiveness.
As for the materials for creation, in general, worm is made from 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 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 trimming 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 many gears at once by stacking the gear blanks as can be carried out with spur gears.
