low backlash planetary gearbox

We has over 30 years’ experience with reduction gearbox design and manufacturing. Our dependable, high performance power transfer solutions are available in many 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 built in compact frames and offer at output that is 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional single- and double-output shafts, worm gear styles are versatile enough for a wide array of applications. Durable aluminum and steel materials make these worm reduction gearboxes perfect for harsh working conditions.

We offers worm equipment designs in a range of torque values and with various input/output sizes to fit your requirements. Like all our gearboxes, these low backlash planetary gearbox products are manufactured for low backlash (≤30 arc mins backlash or less) and high effectiveness (up to 90% at 1,000 RPM).
With its three product variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves absolutely nothing to be desired so far as performance, smooth running and versatility are concerned. The right solution exists for just about any specific torsional backlash higher than 2 arcmin. Features such as maximum economy in all axes, optimum 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 along with optimal reliability and optimum economy within a lifespan greater than 20,000 hours.
Worm gears are often used when large speed reductions are needed. The decrease ratio depends upon the number of starts of the worm and number of teeth on the worm equipment. But worm gears possess sliding contact which is quiet but tends to produce heat and also have relatively low transmission effectiveness.

As for the materials for production, in general, worm is made of hard metal as the worm gear is made from relatively soft metal such as for example aluminum bronze. This is since the number of the teeth 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 the teeth is reduced. Another characteristic of worm manufacturing may be 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 utilized for spur gears. But due to the different tooth shape, it is not possible to cut a number of gears at once by stacking the gear blanks as can be done with spur gears.
