low backlash worm reducer

We has over 30 years’ experience with decrease gearbox design and manufacturing. Our dependable, powerful power low backlash worm reducer 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 applications.
Our NEMA gearboxes are built in compact frames and offer 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 designs are versatile enough for a wide array of applications. Durable aluminum and steel materials make these worm decrease gearboxes ideal 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 models are manufactured for low backlash (≤30 arc a few minutes 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 so far as performance, smooth working and versatility are concerned. The right solution exists for just about any specified torsional backlash greater than 2 arcmin. Characteristics such as maximum economy in all axes, maximum torque density and continuous, low torsional backlash through the entire service life are normal to all or any of the gearboxes.
these servo worm gearboxes give you best-in-class precision – tailored precision up to ≤ 2 arcminutes for a variety of applications. You profit from rapid availability along with optimal reliability and optimum economy throughout a lifespan greater than 20,000 hours.
Worm gears are often used when large quickness reductions are needed. The decrease ratio depends upon the number of begins of the worm and quantity of tooth on the worm equipment. But worm gears have sliding contact which is noiseless but tends to produce heat and also have relatively low transmission efficiency.

For the materials for creation, in general, worm is made of hard metal as the worm gear is made from relatively soft metal such as aluminum bronze. This is since the number of teeth on the worm equipment is relatively high compared to worm with its number of starts being usually 1 to 4, by reducing the worm gear hardness, the friction on the worm teeth is reduced. Another characteristic of worm manufacturing may be the need of specialized machine for gear cutting and tooth grinding of worms. The worm equipment, however, may be made with the hobbing machine utilized for spur gears. But due to the different tooth shape, it isn’t possible to cut several gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
