low backlash worm reducer

We has over 30 years’ experience with reduction gearbox design and production. Our dependable, high performance power transfer solutions can be found in numerous sizes and configurations, with torque rankings up to 420Nm to meet our customers’ requirements. Our flange gear 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 solitary- and double-result low backlash worm reducer shafts, worm gear designs are versatile enough for a wide array of applications. Durable aluminium and steel components make these worm decrease gearboxes ideal for harsh working conditions.

We offers worm gear designs in a variety of torque values 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 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 operating and versatility are concerned. The right solution exists for just about any specified torsional backlash higher than 2 arcmin. Attributes such as for example maximum economy in every 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 give you best-in-course 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 usually used when large speed reductions are needed. The decrease ratio depends upon the number of begins of the worm and amount of the teeth on the worm gear. But worm gears possess sliding get in touch with which is silent but will produce heat and also have relatively low transmission performance.

For the materials for creation, in general, worm is made from hard metal as the worm gear is made from relatively soft metal such as for example aluminum bronze. That is since the number of teeth on the worm equipment is relatively high compared to worm using its number of starts being usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm the teeth is reduced. Another feature of worm manufacturing is the need of specialized machine for gear trimming and tooth grinding of worms. The worm gear, on the other hand, may be made with the hobbing machine utilized for spur gears. But because of the various tooth shape, it is not possible to cut many gears at once by stacking the gear blanks as can be done with spur gears.
