We has over 30 years’ experience with decrease gearbox design and production. Our dependable, high performance power transfer solutions can be found in several sizes and configurations, with torque rankings up to 420Nm to meet up our clients’ requirements. Our flange gear reducers are perfect for a broad low backlash planetary gearbox spectrum of applications.
Our NEMA gearboxes are built in small frames and offer at output that’s 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional solitary- and double-output shafts, worm gear designs are versatile enough for several applications. Durable light weight aluminum and steel materials make these worm decrease gearboxes well suited for harsh working conditions.
We offers worm equipment designs in a range of torque ideals and with various input/output sizes to fit your requirements. Like all our gearboxes, these systems are engineered for low backlash (≤30 arc moments backlash or less) and high performance (up to 90% at 1,000 RPM).
With its three item variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves absolutely nothing to be desired so far as performance, smooth operating and flexibility are concerned. A suitable solution exists for any specific torsional backlash greater than 2 arcmin. Characteristics such as for example maximum economy in every axes, optimum 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 offer you best-in-course 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 greater than 20,000 hours.
Worm gears are often used when large acceleration reductions are needed. The reduction ratio depends upon the number of starts of the worm and 
quantity of the teeth on the worm gear. But worm gears possess sliding contact which is calm but tends to produce heat and also have relatively low transmission performance.
As for the materials for production, in general, worm is made from hard metal while the worm gear is made from relatively soft metallic such as for example aluminum bronze. That is because the number of tooth on the worm equipment is relatively high compared to worm using its number of starts being generally 1 to 4, by reducing the worm gear hardness, the friction on the worm tooth is reduced. Another characteristic of worm manufacturing is the need of specialized machine for gear slicing and tooth grinding of worms. The worm gear, however, 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 at once by stacking the apparatus blanks as can be carried out with spur gears.
