We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, high performance power transfer solutions are available in several sizes and configurations, with torque rankings up to 420Nm to meet up our clients’ requirements. Our flange equipment reducers are perfect for a broad spectrum of applications.
Our NEMA gearboxes are designed in compact frames and provide at output that is 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional one- and double-result shafts, worm gear designs are versatile enough for a wide array of applications. Durable aluminum and steel materials make these worm decrease gearboxes well suited for harsh working conditions.

We offers worm gear designs in a range of torque values and with various insight/output sizes to match your requirements. Like all our gearboxes, these models are designed for low backlash (≤30 arc minutes backlash or less) and high effectiveness (up to 90% at 1,000 RPM).
With its three product variants, the new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired so far as performance, smooth running and versatility are concerned. The right solution exists for any specified torsional backlash greater than 2 arcmin. Attributes such as maximum economy in all axes, optimum torque density and constant, low torsional backlash throughout the service life are normal to all of the gearboxes.
these servo worm gearboxes offer you best-in-course precision – tailored precision up to ≤ 2 arcminutes for a number of applications. You profit from rapid availability in addition to optimal reliability and maximum economy within a lifespan of more than 20,000 hours.
Worm gears are usually used when large velocity reductions are needed. The reduction ratio is determined by the number of starts of the worm and quantity of the teeth on the worm equipment. But worm gears possess sliding get in touch with which is noiseless but will produce heat and have relatively low transmission efficiency.

For the materials for low backlash planetary gearbox production, 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. That is since the number of teeth on the worm gear is relatively high compared to worm using its number of starts being usually 1 to 4, by reducing the worm gear hardness, the friction on the worm tooth is reduced. Another feature of worm manufacturing may be the need of specialized machine for gear cutting and tooth grinding of worms. The worm gear, however, may be made out of the hobbing machine used for spur gears. But because of the various tooth shape, it is not possible to cut a number of gears simultaneously by stacking the gear blanks as can be carried out with spur gears.
