We has over 30 years’ experience with reduction gearbox design and production. Our dependable, powerful power transfer solutions are available in several sizes and configurations, with torque rankings up to 420Nm to meet up our clients’ requirements. Our flange gear reducers are ideal for a broad spectrum of applications.
Our NEMA gearboxes are built in compact frames and offer at output that is 90° from the input. Along with decrease ratios from 5:1 to 120:1 and optional single- and double-output shafts, worm gear designs are versatile enough for a wide array of applications. Durable aluminum and steel materials make these worm decrease gearboxes ideal for harsh working conditions.

We offers worm gear designs in a range of torque ideals and with various insight/output sizes to fit your requirements. Like all our gearboxes, these systems are manufactured for low backlash (≤30 arc mins backlash or less) and high effectiveness (up to 90% at 1,000 RPM).
With its three product variants, the new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired so 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 for example maximum economy in every axes, maximum torque density and continuous, low torsional backlash through the entire service life are common to all of the gearboxes.
these servo worm gearboxes offer you best-in-course precision – tailored precision up to ≤ 2 arcminutes for a number of applications. You profit from rapid availability in addition to optimal reliability and maximum economy throughout a lifespan greater than 20,000 hours.
Worm gears are often used when large quickness reductions are needed. The decrease ratio depends upon the number of starts of the worm and quantity of the teeth on the worm equipment. But worm gears have sliding contact which is peaceful but will produce heat and have relatively low transmission efficiency.

As for the materials for creation, in general, worm is constructed of hard metal as the worm gear is made from relatively soft steel such as aluminum bronze. That is because the number of tooth on the worm gear is relatively high compared to worm with its number of starts being usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm tooth is reduced. Another feature of worm manufacturing may be the need of specific machine for gear cutting and tooth low backlash planetary gearbox grinding of worms. The worm gear, on the other hand, may be made out of the hobbing machine utilized for spur gears. But due to the different tooth shape, it is not possible to cut a number of gears simultaneously by stacking the apparatus blanks as can be carried out with spur gears.
