We has over 30 years’ experience with reduction gearbox design and manufacturing. Our dependable, powerful power transfer solutions can be found in many sizes and configurations, with torque rankings up to 420Nm to meet our customers’ requirements. Our flange equipment reducers are ideal for a broad spectral range of low backlash worm reducer applications.
Our NEMA gearboxes are built 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 one- and double-output shafts, worm gear designs are versatile enough for several applications. Durable aluminum and steel materials make these worm decrease gearboxes perfect for harsh working conditions.

We offers worm gear designs in a range of torque ideals and with various input/output sizes to match your requirements. Like all our gearboxes, these products are manufactured for low backlash (≤30 arc moments backlash or much less) and high effectiveness (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 operating and flexibility 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 continuous, low torsional backlash throughout the service life are normal to all of the gearboxes.
these servo worm gearboxes offer you best-in-course 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 of more than 20,000 hours.
Worm gears are often used when large rate reductions are needed. The decrease ratio is determined by the number of begins of the worm and number of teeth on the worm gear. But worm gears have sliding get in touch with which is tranquil but will produce heat and also have relatively low transmission performance.

As for the materials for creation, in general, worm is constructed of hard metal while the worm gear is made from relatively soft metallic such as aluminum bronze. This is since the number of tooth on the worm equipment is relatively high compared to worm with its number of starts being generally 1 to 4, by reducing the worm equipment hardness, the friction on the worm teeth is reduced. Another feature of worm manufacturing is the need of specific machine for gear trimming and tooth grinding of worms. The worm gear, however, may be made out of the hobbing machine utilized for spur gears. But because of the different tooth shape, it is not possible to cut several gears at once by stacking the gear blanks as can be carried out with spur gears.
