We has over 30 years’ experience with reduction gearbox design and production. Our dependable, powerful power transfer solutions can be found in several sizes and configurations, with torque rankings up to 420Nm to meet up our customers’ requirements. Our flange equipment reducers are ideal for a broad spectrum of applications.
Our NEMA gearboxes are 
built in compact frames and provide at output that’s 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional single- and double-result shafts, worm gear designs are versatile enough for several applications. Durable aluminum and steel components 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 fit your requirements. Like all our gearboxes, these devices are manufactured for low backlash (≤30 arc minutes backlash or less) and high effectiveness (up to 90% at 1,000 RPM).
With its three item variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired as far as performance, smooth operating and versatility are concerned. A suitable solution exists for any specific torsional backlash higher than 2 arcmin. Features such as maximum economy in all axes, maximum torque density and constant, low torsional backlash low backlash planetary gearbox throughout the service life are common to all 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 and also optimal reliability and maximum economy throughout a lifespan of more than 20,000 hours.
Worm gears are often used when large speed reductions are needed. The decrease ratio depends upon the number of starts of the worm and number of tooth on the worm gear. But worm gears have sliding contact which is calm but tends to produce heat and have relatively low transmission efficiency.
As for the materials for creation, in general, worm is constructed of hard metal as the worm gear is manufactured out of relatively soft metal such as for example aluminum bronze. This is because the number of the teeth on the worm equipment is relatively high compared to worm using its number of begins being usually 1 to 4, by reducing the worm gear hardness, the friction on the worm the teeth is reduced. Another feature 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 out of 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.
