We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, high performance power transfer solutions can be found in numerous sizes and configurations, with torque ratings up to 420Nm to meet up our customers’ requirements. Our flange equipment reducers are ideal for a broad spectral range of applications.
Our NEMA gearboxes are designed in small frames and offer at output that is 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional single- and double-result shafts, worm gear designs are versatile enough for a wide array of applications. Durable aluminum and steel materials 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 match your requirements. Like all our gearboxes, these models are engineered for low backlash (≤30 arc a few minutes backlash or less) and high performance (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 working and flexibility are concerned. The right solution exists for any specified torsional backlash greater than 2 arcmin. Characteristics such as maximum low backlash worm reducer economy in every axes, maximum torque density and continuous, low torsional backlash through the entire service life are normal 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 number of applications. You benefit from rapid availability along with optimal reliability and maximum economy throughout a lifespan greater than 20,000 hours.
Worm gears are often used when large velocity reductions are needed. The decrease ratio depends upon the number of begins of the worm and amount of tooth on the worm equipment. But worm gears possess sliding get in touch with which is calm but tends to produce heat and have relatively low transmission efficiency.

For the materials for creation, in general, worm is made of hard metal as the worm gear is made from relatively soft metal such as aluminum bronze. This is since the number of the teeth on the worm gear 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 teeth is reduced. Another feature of worm manufacturing is the need of specialized machine for gear slicing and tooth grinding of worms. The worm gear, however, may be made out of the hobbing machine utilized for spur gears. But due to the various tooth shape, it isn’t possible to cut a number of gears simultaneously by stacking the gear blanks as can be carried out with spur gears.
