We has over 30 years’ experience with reduction gearbox design and manufacturing. Our dependable, high performance power transfer solutions can be found in numerous sizes and configurations, with torque ratings up to 420Nm to meet up 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 is 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional solitary- and double-output shafts, worm gear designs are versatile enough for several applications. Durable light weight aluminum and steel components make these worm reduction gearboxes ideal for harsh working conditions.
We offers worm gear designs in a range of torque ideals and with various insight/output sizes to fit your requirements. Like all our gearboxes, these devices are manufactured for low backlash (≤30 arc mins 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 as far as performance, smooth operating 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 all axes, optimum torque density and continuous, 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 number of applications. You benefit from rapid availability in addition to optimal reliability and optimum economy throughout a lifespan greater than 20,000 hours.
Worm gears are usually used when large rate reductions are needed. The reduction ratio depends upon the number of begins of the worm and amount of the teeth on the worm gear. But worm gears have sliding contact which is quiet but will produce heat and also have relatively low transmission efficiency.
For the materials for creation, in general, worm is made from hard metal while the worm gear is made from 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 begins being usually 1 to 4, by low backlash worm reducer reducing the worm gear hardness, the friction on the worm tooth is reduced. Another characteristic of worm manufacturing is the need of specialized machine for gear cutting and tooth grinding of worms. The worm gear, on the other hand, may be made out of the hobbing machine used for spur gears. But due to the various tooth shape, it is not possible to cut several gears at once by stacking the gear blanks as can be done with spur gears.
