We has over 30 years’ experience with decrease gearbox design and production. Our dependable, powerful power transfer solutions can be 
found in numerous sizes and configurations, with torque ratings up to 420Nm to meet up our customers’ requirements. Our flange gear reducers are ideal for a broad spectral range of applications.
Our NEMA gearboxes are designed in compact frames and offer at output that's 90° from the insight. Along with reduction ratios from 5:1 to 120:1 and optional single- and double-output shafts, worm gear designs are versatile enough for a wide array of applications. Durable aluminium and steel materials make these worm decrease gearboxes well suited for harsh working conditions.
We offers worm equipment designs in a range of torque values and with various input/output sizes to match your requirements. Like all our gearboxes, these models 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 low backlash planetary gearbox performance, smooth working and versatility are concerned. The right solution exists for just about any specified torsional backlash higher than 2 arcmin. Features such as for example maximum economy in every axes, maximum 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 benefit from rapid availability along with optimal reliability and optimum economy within a lifespan greater than 20,000 hours.
Worm gears are often used when large velocity reductions are needed. The reduction ratio depends upon the number of starts of the worm and quantity of tooth on the worm equipment. But worm gears possess sliding get in touch with which is calm but tends to produce heat and have relatively low transmission efficiency.
For the materials for production, in general, worm is made of hard metal while the worm gear is made from relatively soft metal such as for example aluminum bronze. That is since 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 may be the need of specialized machine for gear cutting and tooth grinding of worms. The worm gear, on the other hand, may be made with the hobbing machine used for spur gears. But because of the various tooth shape, it is not possible to cut several gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
