low backlash planetary gearbox

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 ratings up to 420Nm to meet our clients’ 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 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 aluminium and steel components 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 designed for low backlash (≤30 arc a few minutes 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 operating and flexibility are concerned. A suitable solution exists for any specific torsional backlash higher than 2 arcmin. Features such as maximum economy in all axes, maximum torque density and constant, low torsional backlash through the entire service life are common to all or any of the gearboxes.
these servo worm gearboxes offer you best-in-class precision – tailored precision up to ≤ 2 arcminutes for a variety of applications. You benefit from rapid availability as well as optimal reliability and maximum economy within a lifespan greater than 20,000 hours.
Worm gears are usually used when large rate reductions are needed. The reduction ratio depends upon the number of starts of the worm and amount of the teeth on the worm gear. But worm gears have sliding contact which is quiet but tends to low backlash planetary gearbox produce heat and also 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 for example aluminum bronze. That is since the number of teeth on the worm gear is relatively high compared to worm with its number of starts being usually 1 to 4, by reducing the worm gear hardness, the friction on the worm the teeth 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 used for spur gears. But because of the different tooth shape, it is not possible to cut a number of gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
