low backlash worm reducer

We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, powerful power transfer solutions are available in many sizes and configurations, with torque rankings up to 420Nm to meet up our clients’ requirements. Our flange equipment reducers are perfect for a broad spectral range of applications.
Our NEMA gearboxes are built in small frames and offer at output that’s 90° from the input. 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 light weight aluminum and steel materials make these worm decrease gearboxes ideal for harsh working conditions.

We offers worm equipment designs in a variety of torque low backlash worm reducer values and with various input/output sizes to match your requirements. Like all our gearboxes, these models are manufactured 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 absolutely nothing to be desired as far as performance, smooth running and versatility are concerned. A suitable solution exists for any specified torsional backlash higher than 2 arcmin. Features such as maximum economy in every axes, optimum 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 greater than 20,000 hours.
Worm gears are usually used when large acceleration reductions are needed. The decrease ratio depends upon the number of begins of the worm and number of tooth on the worm equipment. But worm gears possess sliding get in touch with which is silent but tends to produce heat and also have relatively low transmission performance.

As for the materials for creation, in general, worm is made of hard metal while the worm gear is manufactured out of relatively soft metallic such as for example aluminum bronze. This is since the number of teeth on the worm equipment is relatively high in comparison to worm using its number of begins being generally 1 to 4, by reducing the worm gear hardness, the friction on the worm the teeth is reduced. Another characteristic of worm manufacturing is the need of specialized machine for gear slicing and tooth grinding of worms. The worm equipment, however, may be made with the hobbing machine used for spur gears. But because of the various tooth shape, it isn’t possible to cut several gears at once by stacking the apparatus blanks as can be done with spur gears.
