low backlash planetary gearbox

We has over 30 years’ experience with decrease gearbox design and production. Our dependable, high performance power transfer low backlash planetary gearbox solutions can be found in many sizes and configurations, with torque rankings up to 420Nm to meet up our customers’ requirements. Our flange gear reducers are well suited for a broad spectral range of applications.
Our NEMA gearboxes are designed in small frames and provide at output that is 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional one- and double-result shafts, worm gear styles are versatile enough for several applications. Durable aluminum and steel materials make these worm decrease gearboxes ideal for harsh working conditions.

We offers worm equipment designs in a range of torque ideals and with various input/output sizes to fit your requirements. Like all our gearboxes, these units are engineered for low backlash (≤30 arc mins backlash or much 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 as far as performance, smooth running and versatility are concerned. The right solution exists for just about any specified torsional backlash greater than 2 arcmin. Features such as maximum economy in all axes, maximum torque density and constant, low torsional backlash throughout the service life are common to all or any of the gearboxes.
these servo worm gearboxes give you best-in-class precision – tailored precision up to ≤ 2 arcminutes for a variety of applications. You profit from rapid availability as well as optimal reliability and maximum economy throughout a lifespan greater than 20,000 hours.
Worm gears are usually used when large velocity reductions are needed. The decrease ratio depends upon the number of starts of the worm and quantity of the teeth on the worm gear. But worm gears possess sliding contact which is tranquil 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 manufactured out of relatively soft metallic such as for example aluminum bronze. This is because the number of the teeth on the worm equipment is relatively high compared to worm using its number of starts being generally 1 to 4, by reducing the worm gear hardness, the friction on the worm tooth is reduced. Another characteristic of worm manufacturing may be the need of specific machine for gear slicing and tooth grinding of worms. The worm gear, however, may be made with the hobbing machine utilized for spur gears. But because of the different tooth shape, it is not possible to cut several gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
