We has over 30 years’ experience with decrease 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 perfect for a broad spectral range of applications.
Our NEMA gearboxes are built in small frames and offer at output that’s 90° from the input. 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 gear designs in a variety of torque values and with various input/output sizes to match your requirements. Like all our gearboxes, these devices are designed for low backlash (≤30 arc moments backlash or less) and high effectiveness (up to 90% at 1,000 RPM).
With its three product variants, the brand new servo worm gearbox series from WITTENSTEIN alpha leaves nothing to be desired so far as performance, smooth working and versatility are concerned. A suitable solution exists for any specified torsional backlash higher than 2 arcmin. Features such as maximum economy in all axes, maximum torque density and continuous, low torsional backlash throughout the service life are common 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 low backlash planetary gearbox number of applications. You profit from rapid availability along with optimal reliability and optimum economy within a lifespan greater than 20,000 hours.
Worm gears are usually used when large velocity reductions are needed. The reduction ratio depends upon the number of starts of the worm and number of tooth on the worm equipment. But worm gears possess sliding contact which is tranquil but tends to produce heat and have relatively low transmission performance.
As for the materials for creation, in general, worm is constructed of hard metal as the worm gear is made from relatively soft steel such as for example aluminum bronze. This is because the number of the 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 the teeth is reduced. Another characteristic of worm manufacturing is the need of specialized machine for gear reducing 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 because of the different tooth shape, it is not possible to cut many gears simultaneously by stacking the gear blanks as can be done with spur gears.
