low backlash planetary gearbox

We has over 30 years’ experience with reduction gearbox design and manufacturing. Our dependable, high performance power transfer solutions are available in many sizes and configurations, with torque rankings up to 420Nm to meet our customers’ requirements. Our flange equipment reducers are perfect for a broad spectrum of applications.
Our NEMA gearboxes are designed in compact frames and provide at output that is 90° from the input. Along with reduction 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 components make these worm decrease 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 models are engineered for low low backlash planetary gearbox backlash (≤30 arc mins backlash or much 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. A suitable solution exists for any specified torsional backlash higher than 2 arcmin. Characteristics such as maximum economy in every axes, maximum torque density and constant, low torsional backlash through the entire 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 number of applications. You benefit from rapid availability in addition to optimal reliability and optimum economy within a lifespan of more than 20,000 hours.
Worm gears are usually used when large acceleration reductions are needed. The reduction ratio is determined by the number of begins of the worm and number of tooth on the worm gear. But worm gears have sliding get in touch with which is calm but will produce heat and have relatively low transmission performance.

As for the materials for production, in general, worm is made of hard metal while the worm gear is manufactured out of relatively soft steel such as aluminum bronze. This is since the number of teeth 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 teeth is reduced. Another characteristic of worm manufacturing is the need of specialized machine for gear slicing and tooth grinding of worms. The worm gear, on the other hand, may be made out of the hobbing machine utilized for spur gears. But due to the different tooth shape, it is not possible to cut a number of gears simultaneously by stacking the apparatus blanks as can be done with spur gears.
