We has over 30 years’ experience with decrease gearbox design and production. Our dependable, powerful power transfer solutions can be found in several sizes and configurations, with torque ratings 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 designed 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 solitary- and double-result shafts, worm gear styles are versatile enough for a wide array of applications. Durable light weight aluminum and steel materials make these worm reduction gearboxes ideal for harsh low backlash worm reducer working conditions.
We offers worm equipment designs in a variety of torque values and with various insight/output sizes to fit your requirements. Like all our gearboxes, these units are designed for low backlash (≤30 arc a few minutes backlash or less) and high performance (up to 90% at 1,000 RPM).
With its three item variants, the new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired as far as performance, smooth running and versatility are concerned. The right solution exists for just about any specific torsional backlash greater than 2 arcmin. Features such as 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-class precision – tailored precision up to ≤ 2 arcminutes for a number of applications. You benefit from rapid availability as well as optimal reliability and optimum economy throughout a lifespan of more than 20,000 hours.
Worm gears are often used when large quickness reductions are needed. The reduction ratio is determined by the number of starts of the worm and quantity of tooth on the worm equipment. But worm gears possess sliding contact which is silent but tends to produce heat and have relatively low transmission effectiveness.
As for the materials for production, in general, worm is made of hard metal as the worm gear is manufactured out of relatively soft steel such as for example aluminum bronze. That is because the number of the teeth on the worm gear 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 tooth is reduced. Another characteristic of worm manufacturing may be the need of specialized machine for gear slicing and tooth grinding of worms. The worm equipment, on the other hand, may be made with the hobbing machine used for spur gears. But due to the various tooth shape, it isn’t possible to cut a number of gears simultaneously by stacking the gear blanks as can be done with spur gears.
