We has over 30 years’ experience with reduction gearbox design and production. Our dependable, powerful power transfer solutions can be found in numerous sizes and configurations, with torque rankings up to 420Nm to meet up our clients’ requirements. Our flange equipment reducers are well suited for a broad spectral range of applications.
Our NEMA gearboxes are built in small frames and provide at output that is 90° from the input. Along with decrease ratios from 5:1 to 120:1 and optional single- and double-output shafts, worm gear styles are versatile enough for a wide array of applications. Durable aluminum and steel components make these worm decrease gearboxes well suited for harsh working conditions.
We offers worm gear designs in a range of torque ideals and with various insight/output sizes to match your requirements. Like all our gearboxes, these systems are engineered for low backlash (≤30 arc minutes backlash or much less) and high effectiveness (up to 90% at 1,000 RPM).
With its three product variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired as far as performance, smooth working and versatility are concerned. A suitable solution exists for just about any specified torsional backlash greater than 2 arcmin. Characteristics such as for example maximum economy in all axes, optimum torque density and continuous, low torsional backlash through the entire 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 number of applications. You profit from rapid availability in addition to optimal reliability and optimum economy within a lifespan greater than 20,000 hours.
Worm gears are often used when large quickness reductions are needed. The decrease ratio is determined by the number of starts of the worm and amount of the teeth on the worm equipment. But worm gears have sliding get in touch with which is peaceful but will produce heat and have relatively low transmission effectiveness.
For the materials for production, in general, worm is made 
of hard metal as the worm gear is manufactured out of relatively soft metallic such as for example aluminum bronze. That is since the number of the teeth on the worm gear is relatively high compared to worm using its number of begins being generally 1 to 4, by reducing the worm equipment hardness, the friction on the worm tooth is reduced. Another feature of worm manufacturing is the need of specialized machine for gear reducing and tooth grinding of worms. The worm equipment, on the other hand, may be made with the hobbing machine used for spur gears. But because of the different tooth shape, it is not possible to cut several gears low backlash planetary gearbox simultaneously by stacking the gear blanks as can be carried out with spur gears.
