We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, powerful power transfer solutions are available in numerous sizes and configurations, with torque rankings up to 420Nm to meet up our customers’ requirements. Our flange equipment reducers are well suited for a broad spectral range of applications.
Our NEMA gearboxes are low backlash worm reducer designed in small frames and offer at output that’s 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional solitary- and double-output shafts, worm gear designs are versatile enough for several applications. Durable aluminum and steel components make these worm reduction gearboxes perfect 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 models are engineered for low backlash (≤30 arc mins 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 nothing to be desired so far as performance, smooth running and flexibility are concerned. A suitable solution exists for any specified torsional backlash greater than 2 arcmin. Features such as for example maximum economy in all axes, maximum 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-class precision – tailored precision up to ≤ 2 arcminutes for a number of applications. You profit from rapid availability as well as optimal reliability and maximum economy throughout a lifespan of more than 20,000 hours.
Worm gears are often used when large velocity reductions are needed. The reduction ratio depends upon the number of begins of the worm and amount of teeth on the worm gear. But worm gears possess sliding get in touch with which is noiseless but tends to produce heat and have relatively low transmission effectiveness.
As for the materials for production, in general, worm is made from hard metal while the worm gear is made from relatively soft metallic such as aluminum bronze. That is because the number of tooth on the worm equipment is relatively high in comparison to worm using 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 specialized machine for gear cutting 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 isn’t possible to cut a number of gears simultaneously by stacking the gear blanks as can be carried out with spur gears.
