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 ratings up to 420Nm to meet our clients’ requirements. Our low backlash worm reducer flange equipment reducers are well suited for a broad spectrum of applications.
Our NEMA gearboxes are built in small frames and offer at output that is 90° from the insight. Along with decrease ratios from 5:1 to 120:1 and optional single- and double-result shafts, worm gear designs are versatile enough for a wide array of applications. Durable aluminium and steel materials make these worm reduction gearboxes ideal for harsh working conditions.

We offers worm equipment designs in a variety of torque ideals and with various insight/output sizes to match your requirements. Like all our gearboxes, these products are engineered for low backlash (≤30 arc moments backlash or less) and high effectiveness (up to 90% at 1,000 RPM).
With its three item variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired as far as performance, smooth operating and versatility are concerned. The right solution exists for any specified torsional backlash higher than 2 arcmin. Attributes such as for example maximum economy in all axes, maximum torque density and continuous, low torsional backlash through the entire service life are common to all or any of the gearboxes.
these servo worm gearboxes give you best-in-course precision – tailored precision up to ≤ 2 arcminutes for a number of applications. You benefit from rapid availability and also optimal reliability and optimum economy within a lifespan greater than 20,000 hours.
Worm gears are often used when large speed reductions are needed. The decrease ratio is determined by the number of begins of the worm and quantity of teeth on the worm equipment. But worm gears possess sliding contact which is tranquil but will produce heat and have relatively low transmission effectiveness.

For the materials for creation, in general, worm is made of hard metal as the worm gear is made from relatively soft metallic such as aluminum bronze. This is because 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 equipment hardness, the friction on the worm tooth is reduced. Another characteristic of worm manufacturing is the need of specific machine for gear trimming and tooth grinding of worms. The worm equipment, however, may be made with the hobbing machine used for spur gears. But due to the different tooth shape, it is not possible to cut a number of gears simultaneously by stacking the gear blanks as can be done with spur gears.
