low backlash worm reducer

We has over 30 years’ experience with reduction gearbox design and production. Our dependable, powerful power transfer solutions are available in numerous sizes and configurations, with torque rankings up to 420Nm to meet our customers’ requirements. Our flange equipment reducers are ideal for a broad spectral range of applications.
Our NEMA gearboxes are built in compact frames and offer at output that’s 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional one- and double-result shafts, worm gear designs are versatile enough for several applications. Durable aluminum and steel materials make these worm reduction gearboxes perfect for harsh working conditions.

We offers worm gear designs in a variety of torque values and with various input/output sizes to match your requirements. Like all our gearboxes, these models are engineered for low backlash (≤30 arc moments backlash or much less) and high performance (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 flexibility are concerned. The right solution exists for any specific torsional backlash greater than 2 arcmin. Attributes such as maximum economy in every axes, maximum torque density and continuous, low torsional backlash throughout the service life are normal to all or any of the gearboxes.
these servo worm gearboxes offer you best-in-course precision – tailored precision up to ≤ 2 arcminutes for a variety of applications. You profit from rapid availability along with optimal reliability and optimum economy within a lifespan of more than 20,000 hours.
Worm gears are usually used when large swiftness reductions are needed. The decrease ratio is determined by the number of starts of the worm and amount of the teeth on the worm equipment. But worm gears have sliding contact which is silent but tends to produce heat and have low backlash worm reducer relatively low transmission efficiency.

For the materials for creation, in general, worm is constructed of hard metal as the worm gear is made from relatively soft steel such as aluminum bronze. This is because the number of tooth on the worm gear is relatively high in comparison to worm with its number of starts being usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm tooth is reduced. Another characteristic of worm manufacturing is the need of specific machine for gear cutting and tooth grinding of worms. The worm gear, on the other hand, may be made with the hobbing machine utilized for spur gears. But due to the various tooth shape, it isn’t possible to cut several gears simultaneously by stacking the apparatus blanks as can be carried out with spur gears.
