low backlash planetary gearbox

We has over 30 years’ experience with reduction gearbox design and manufacturing. Our dependable, high performance power transfer solutions can be found in numerous sizes and configurations, with torque ratings 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 designed in small frames and provide at output that’s 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional single- and double-result shafts, worm gear designs are low backlash planetary gearbox versatile enough for several applications. Durable aluminum and steel components make these worm decrease gearboxes well suited 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 models are designed for low backlash (≤30 arc a few minutes backlash or much less) and high performance (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 as far as performance, smooth running and versatility are concerned. The right solution exists for any specified torsional backlash greater than 2 arcmin. Features such as for example maximum economy in every axes, optimum torque density and continuous, low torsional backlash through the entire service life are normal to all or any of the gearboxes.
these servo worm gearboxes give you best-in-course precision – tailored precision up to ≤ 2 arcminutes for a number of applications. You benefit from rapid availability along with optimal reliability and optimum economy within a lifespan of more than 20,000 hours.
Worm gears are often used when large velocity reductions are needed. The reduction ratio depends upon the number of begins of the worm and number of the teeth on the worm equipment. But worm gears possess sliding contact which is noiseless but will produce heat and also have relatively low transmission effectiveness.

As for the materials for production, in general, worm is made from hard metal while the worm gear is manufactured out of relatively soft metal such as for example aluminum bronze. That is because the number of teeth on the worm equipment is relatively high compared to worm with its number of begins 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 specialized machine for gear reducing and tooth grinding of worms. The worm equipment, on the other hand, may be made with the hobbing machine used for spur gears. But because of the different tooth shape, it isn’t possible to cut several gears at once by stacking the gear blanks as can be carried out with spur gears.
