We has over 30 years’ experience with decrease 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 up our customers’ requirements. Our flange equipment reducers are ideal for a broad spectrum of applications.
Our NEMA gearboxes are 
designed in small frames and provide at output that is 90° from the input. Along with reduction ratios from 5:1 to 120:1 and low backlash worm reducer optional single- and double-output shafts, worm gear designs are versatile enough for several applications. Durable aluminum and steel components 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 input/output sizes to match your requirements. Like all our gearboxes, these systems are engineered for low backlash (≤30 arc minutes backlash or less) and high effectiveness (up to 90% at 1,000 RPM).
With its three item variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired as far as performance, smooth running and flexibility are concerned. The right solution exists for just about any specified torsional backlash greater than 2 arcmin. Features such as 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 variety of applications. You benefit from rapid availability as well as optimal reliability and optimum economy throughout a lifespan greater than 20,000 hours.
Worm gears are often used when large rate reductions are needed. The reduction ratio depends upon the number of starts of the worm and number of the teeth on the worm gear. But worm gears have sliding contact which is quiet but will produce heat and also have relatively low transmission effectiveness.
For the materials for creation, in general, worm is made from hard metal as the worm gear is made from relatively soft metal such as aluminum bronze. This is because the number of teeth on the worm equipment is relatively high in comparison to worm using its number of begins being generally 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 specific machine for gear reducing and tooth grinding of worms. The worm gear, however, may be made out of the hobbing machine used for spur gears. But because of the various tooth shape, it is not possible to cut several gears simultaneously by stacking the gear blanks as can be done with spur gears.
