We has over 30 years’ experience with reduction low backlash planetary gearbox gearbox design and production. Our dependable, high performance power transfer solutions can be found in several sizes and configurations, with torque rankings 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 built in small frames and offer at output that is 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional one- and double-result shafts, worm gear styles are versatile enough for several applications. Durable light weight aluminum and steel materials make these worm reduction gearboxes perfect for harsh working conditions.
We offers worm gear designs in a variety of torque ideals and with various insight/output sizes to match your requirements. Like all our gearboxes, these devices 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 item variants, the 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 higher than 2 arcmin. Features such as for example maximum economy in all axes, maximum torque density and constant, low torsional backlash throughout the service life are normal to all or any 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 throughout a lifespan greater than 20,000 hours.
Worm gears are usually used when large speed reductions are needed. The reduction ratio depends upon the number of begins of the worm and quantity of tooth on the worm equipment. But worm gears have sliding get in touch with which is peaceful but will produce heat and have relatively low transmission 
effectiveness.
For the materials for production, in general, worm is constructed of hard metal as the worm gear is manufactured out of relatively soft metal such as for example aluminum bronze. That is since the number of teeth on the worm equipment is relatively high compared to worm with its number of begins being usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm tooth is reduced. Another feature of worm manufacturing is the need of specific machine for gear slicing and tooth grinding of worms. The worm equipment, however, may be made out of the hobbing machine used for spur gears. But due to the different tooth shape, it is not possible to cut several gears simultaneously by stacking the apparatus blanks as can be carried out with spur gears.
