We has over 30 years’ experience with reduction gearbox design and production. Our dependable, high performance power transfer solutions can be found in several sizes and configurations, with torque ratings up to 420Nm to meet our clients’ requirements. Our flange gear reducers are ideal for a broad spectrum of applications.
Our NEMA gearboxes are built in small 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 a wide array of applications. Durable aluminium and steel components make these worm decrease gearboxes well suited for harsh working conditions.
We offers worm equipment designs in a variety of torque ideals and with various input/output sizes to match your requirements. Like all our gearboxes, these devices are designed for low backlash (≤30 arc a few minutes backlash or less) and high performance (up to 90% at 1,000 RPM).
With its three product variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired as far as performance, smooth working and versatility are concerned. The right solution exists for any specified torsional backlash greater than 2 arcmin. Attributes such as maximum economy in all axes, optimum torque density and constant, low torsional backlash through the entire service life are common to all or any 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 profit from rapid availability along with optimal reliability and maximum economy within a lifespan greater than 20,000 hours.
Worm gears are usually used when large velocity reductions are needed. The decrease ratio is determined by the number of starts of the worm and quantity of the teeth on the worm gear. But worm gears have sliding contact which is tranquil but tends to produce heat and also have relatively low transmission efficiency.
For the materials for 
production, in general, worm is made from hard metal as the worm gear is manufactured out of relatively soft metal such as for example aluminum bronze. That is since the number of the teeth on the worm equipment is relatively high in comparison to worm with its number of begins being usually 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 low backlash worm reducer machine for gear reducing and tooth grinding of worms. The worm gear, on the other hand, may be made out of the hobbing machine used for spur gears. But because of the different tooth shape, it is not possible to cut several gears at once by stacking the apparatus blanks as can be done with spur gears.
