We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, powerful power transfer solutions are available in numerous sizes and configurations, with torque rankings up to 420Nm to meet up our clients’ requirements. Our flange gear reducers are ideal for a broad spectrum of low backlash worm reducer applications.
Our NEMA gearboxes are designed in compact frames and provide 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 several applications. Durable aluminium and steel components make these worm reduction gearboxes ideal for harsh working conditions.
We offers worm equipment designs in a range of torque ideals and with various input/output sizes to match your requirements. Like all our gearboxes, these models are designed for low backlash (≤30 arc moments backlash or much less) and high performance (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 as far as performance, smooth working and versatility are concerned. A suitable solution exists for any specified torsional backlash greater than 2 arcmin. Characteristics such as for example maximum economy in every axes, maximum torque density and constant, low torsional backlash throughout the service life are common to all 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 profit from rapid availability in addition to optimal reliability and optimum economy throughout a lifespan of more than 20,000 hours.
Worm gears 
are usually used when large quickness reductions are needed. The reduction ratio depends upon the number of begins of the worm and quantity of teeth on the worm equipment. But worm gears have sliding contact which is tranquil but tends to produce heat and have relatively low transmission efficiency.
As for the materials for production, in general, worm is constructed of hard metal while the worm gear is manufactured out of relatively soft steel such as for example aluminum bronze. That is because the number of teeth on the worm gear is relatively high compared to worm with its number of starts being generally 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 cutting and tooth grinding of worms. The worm equipment, however, may be made out of 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 done with spur gears.
