low backlash worm reducer

We has over 30 years’ experience with decrease gearbox design and production. Our dependable, powerful power transfer solutions can be found in many sizes and configurations, with torque rankings up to 420Nm to meet up our customers’ requirements. Our flange gear reducers are well suited for a broad spectrum of applications.
Our NEMA gearboxes are built in small frames and provide at output that’s 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional one- and double-result shafts, worm gear styles are versatile enough for several applications. Durable light weight aluminum and steel components make these worm reduction gearboxes perfect for harsh working conditions.

We offers worm equipment designs in a low backlash worm reducer variety of torque values and with various input/output sizes to match your requirements. Like all our gearboxes, these devices are engineered for low backlash (≤30 arc minutes 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 so far as performance, smooth running and flexibility are concerned. The right solution exists for any specific torsional backlash greater than 2 arcmin. Features such as maximum economy in every axes, maximum torque density and constant, low torsional backlash throughout the service life are common to all 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 benefit from rapid availability along with optimal reliability and optimum economy throughout a lifespan of more than 20,000 hours.
Worm gears are often used when large acceleration reductions are needed. The decrease ratio is determined by the number of starts of the worm and quantity of the teeth on the worm gear. But worm gears have sliding get in touch with which is tranquil but will produce heat and have relatively low transmission efficiency.

As for the materials for production, in general, worm is constructed of hard metal as the worm gear is manufactured out of relatively soft metallic such as for example aluminum bronze. That is because the number of tooth on the worm gear is relatively high compared to worm with its number of starts being usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm teeth is reduced. Another characteristic of worm manufacturing is the need of specific machine for gear trimming and tooth grinding of worms. The worm gear, on the other hand, may be made out of the hobbing machine used for spur gears. But because of the different tooth shape, it is not possible to cut many gears simultaneously by stacking the apparatus blanks as can be carried out with spur gears.
