We has over 30 years’ experience with decrease gearbox design and production. Our dependable, high performance power transfer solutions can be found in low backlash worm reducer numerous sizes and configurations, with torque ratings up to 420Nm to meet our customers’ requirements. Our flange equipment reducers are well suited for a broad spectrum of applications.
Our NEMA gearboxes are built in compact frames and offer at output that’s 90° from the input. Along with reduction ratios from 5:1 to 120:1 and optional one- 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 variety of torque values and with various input/output sizes to match your requirements. Like all our gearboxes, these devices are engineered for low backlash (≤30 arc mins 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 absolutely nothing to be desired as far as performance, smooth operating and versatility are concerned. The right solution exists for just about any specified torsional backlash greater than 2 arcmin. Features such as for example maximum economy in all axes, optimum torque density and continuous, low torsional backlash throughout the service life are normal to all of the gearboxes.
these servo worm gearboxes give you best-in-class precision – tailored precision up to ≤ 2 arcminutes for a variety of applications. You profit from rapid availability as well as optimal reliability and maximum economy throughout a lifespan greater than 20,000 hours.
Worm gears are usually used when large velocity reductions are needed. The decrease ratio is determined by the number of starts of the worm and number of the teeth on the worm gear. But worm gears possess sliding get in touch with which is peaceful but tends to produce heat and also have relatively low transmission effectiveness.
As for the materials for creation, 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. This is because the number of tooth on the worm gear is relatively high compared to worm with its number of starts being usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm the teeth is reduced. Another feature of worm manufacturing is the need of specialized machine for gear trimming and tooth grinding of worms. The worm gear, however, may be made with the hobbing machine utilized for spur gears. But due to the different tooth shape, it is not possible to cut a number of gears at once by stacking the gear blanks as can be carried out with spur gears.
