We has over 30 years’ experience with reduction gearbox design and production. Our dependable, high performance 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 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-output shafts, worm gear designs are versatile enough for a wide array of applications. Durable light weight aluminum and steel components make these worm reduction gearboxes perfect for harsh working conditions.
We offers worm equipment designs in a range of torque ideals and with various insight/output sizes to match your requirements. Like all our gearboxes, these products are designed for low backlash (≤30 arc a few 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, low backlash worm reducer smooth running and versatility are concerned. A suitable solution exists for just about any specific torsional backlash higher than 2 arcmin. Features such as maximum economy in every 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-course precision – tailored precision up to ≤ 2 arcminutes for a variety of applications. You benefit 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 rate reductions are needed. The reduction ratio is determined by the number of starts of the worm and number of tooth on the worm equipment. But worm gears have sliding contact which is calm but tends to produce heat and have relatively low transmission efficiency.
For the materials for creation, in general, worm is constructed of 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 usually 1 to 4, by reducing the worm equipment hardness, the friction on the worm teeth is reduced. Another characteristic of worm manufacturing is the need of specialized machine for gear reducing and tooth grinding of worms. The worm equipment, however, may be made with the hobbing machine utilized for spur gears. But due to the various tooth shape, it is not possible to cut several gears simultaneously by stacking the gear blanks as can be carried out with spur gears.
