low backlash worm reducer

We has over 30 years’ experience with reduction gearbox design and production. Our dependable, powerful power transfer solutions can be found in many sizes and configurations, with torque rankings up to 420Nm to meet up our customers’ requirements. Our flange equipment reducers are ideal for a broad spectrum of applications.
Our NEMA gearboxes are designed in small frames and provide at output that’s 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional single- and double-result shafts, worm gear styles are versatile enough for several applications. Durable aluminium and steel materials make these worm reduction gearboxes perfect 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 products are manufactured for low backlash (≤30 arc a few minutes backlash or less) and high efficiency (up to 90% at 1,000 RPM).
With its three product variants, the new servo worm gearbox series from WITTENSTEIN alpha leaves absolutely nothing to be desired so far as performance, smooth working and versatility are concerned. A suitable solution exists for any specific torsional backlash greater than 2 arcmin. Attributes such as for example maximum economy in every axes, maximum 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 variety of applications. You profit from rapid availability and also optimal reliability and maximum economy throughout a lifespan greater than 20,000 hours.
Worm gears are usually used when large rate low backlash worm reducer reductions are needed. The reduction ratio depends upon the number of begins of the worm and amount of tooth on the worm equipment. But worm gears possess sliding get in touch with which is tranquil but tends to produce heat and have relatively low transmission performance.

For the materials for creation, in general, worm is made of hard metal as the worm gear is manufactured out of relatively soft metallic such as for example aluminum bronze. This is because the number of tooth on the worm equipment is relatively high compared to worm using its number of starts being generally 1 to 4, by reducing the worm gear hardness, the friction on the worm the teeth is reduced. Another feature of worm manufacturing may be the need of specific machine for gear reducing and tooth grinding of worms. The worm gear, on the other hand, may be made with the hobbing machine used for spur gears. But because of the various tooth shape, it isn’t possible to cut many gears at once by stacking the gear blanks as can be done with spur gears.
