low backlash worm reducer

We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, high performance power transfer solutions are available in low backlash worm reducer several sizes and configurations, with torque rankings up to 420Nm to meet 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 provide at output that is 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional solitary- and double-output shafts, worm gear designs are versatile enough for several applications. Durable light weight aluminum and steel components make these worm reduction gearboxes well suited for harsh working conditions.

We offers worm gear designs in a range of torque ideals and with various input/output sizes to fit your requirements. Like all our gearboxes, these models are manufactured for low backlash (≤30 arc a few minutes backlash or much less) and high efficiency (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 so far as performance, smooth running and flexibility are concerned. A suitable solution exists for just about any specified torsional backlash greater than 2 arcmin. Features such as maximum economy in all axes, optimum torque density and constant, low torsional backlash through the entire service life are normal to all or any 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 in addition to optimal reliability and maximum economy throughout a lifespan greater than 20,000 hours.
Worm gears are often used when large acceleration reductions are needed. The reduction ratio depends upon the number of starts of the worm and number of the teeth on the worm gear. But worm gears possess sliding get in touch with which is peaceful but will produce heat and also have relatively low transmission efficiency.

As for the materials for production, in general, worm is made from hard metal while the worm gear is made from relatively soft steel such as for example aluminum bronze. That is because the number of the 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 the teeth is reduced. Another characteristic of worm manufacturing may be the need of specialized machine for gear reducing 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 different tooth shape, it isn’t possible to cut several gears at once by stacking the gear blanks as can be done with spur gears.
