low backlash planetary gearbox

We has over 30 years’ experience with decrease gearbox design and production. Our dependable, powerful power transfer solutions are available in numerous sizes and configurations, with torque ratings up to 420Nm to meet up our customers’ requirements. Our flange gear reducers are perfect for a broad spectral range of applications.
Our NEMA gearboxes are designed in compact frames and offer at output that is 90° from the input. Along with decrease ratios from 5:1 to 120:1 and optional solitary- and double-result shafts, worm gear styles are versatile enough for a wide array of applications. Durable aluminium and steel components make these worm reduction gearboxes perfect for harsh working conditions.

We offers worm gear designs in a variety of torque ideals and with various input/output sizes to fit your requirements. Like all our gearboxes, these units are manufactured for low backlash (≤30 arc moments 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 absolutely nothing to be desired as far as performance, smooth running and versatility are concerned. A suitable solution exists for any specified torsional backlash greater than 2 arcmin. Features such as for example maximum economy in all axes, maximum 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 variety of applications. You profit from rapid availability as well as optimal reliability and optimum economy throughout a lifespan of more than 20,000 hours.
Worm gears are often used when large velocity reductions are needed. The decrease ratio depends upon the number of begins of the worm and amount of teeth on the worm gear. But worm gears possess sliding get in touch with which is noiseless but tends to produce heat and also have relatively low low backlash planetary gearbox transmission effectiveness.

As for the materials for creation, in general, worm is made from hard metal as the worm gear is manufactured out of relatively soft metal such as for example aluminum bronze. This is since the number of the teeth on the worm gear 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 is the need of specialized machine for gear slicing and tooth grinding of worms. The worm gear, on the other hand, may be made with the hobbing machine used for spur gears. But due to the various tooth shape, it isn’t possible to cut many gears simultaneously by stacking the gear blanks as can be carried out with spur gears.
