A NEW GENERATION of Geared Motors As one of the leading global manufacturers and solutions providers of drive technology, WEG’s aim was to expand its extensive range of products by gear units produced in its own facilities. Perfect coordination of products throughout the drive train has put WEG in a position to offer customers even more superior and efficient solutions. Under the leadership of WEG Gear Systems (formerly known as Watt Drive Antriebstechnik), the challenge was to develop a program which not only meets the current demands of the market, but also satisfied WEG’s high quality requirements....

Highly efficient In line with market Optimised design Less noise

YOUR REQUIREMENTS OUR EXPERTISE WG20 is the first geared motor range to be completely developed in-house at WEG. It comprises helical, parallel shaft, helical bevel and helical worm gear units with torques between 50 and 18,000 Nm. Already the two-stage units excel with their large ratio range, as well as being exceptionally efficient thanks to the sophisticated design. The light aluminium housings of the gear units up to 600 Nm and the robust cast iron housings from 800 Nm provide a highly versatile and reliable product, with a wide range of possible applications. HIGHLY EFFICIENT The gear units...

OPTIMISED DESIGN When creating the new gear unit range, the designers paid particular attention to develop a robust housing, opting for a light aluminium construction for the frame sizes up to 600 Nm. The die casting process used in production not only benefits from a smooth surface for demanding hygienic applications, but also features excellent heat conductivity. The housing design additionally enhances this property. The intelligently designed surface encourages heat dissipation from the internal gear parts, thereby aiding more efficient operation and a longer life. The housings for frame...

The helical gear units come in twelve housing sizes for nominal torques from 50 to 18,000 Nm and are available in both foot and flange designs. While the two smaller gear units (C00 and C01) are able to perform to their full potential with just two stages, the larger sizes C03 to C08 are available in both two or three stages for applications in higher torque ranges. From size C09 there is an additional fourth stage, while the C16 is even equipped with 5 gear stages.

Design versions Foot Standard mounting dimensions Typical areas of application Taking the most significant standard mounting dimensions available into account, the design allows for easy integration of WG20 geared motors into almost any existing systems. Machines for timber processing companies, presses, conveyor belts, rotary tables, pumps, packaging machines, bakery equipment, lifts, looms, screw conveyors and screw compressors. Gear size

Parallel shaft geared motors F Thanks to their structural design, parallel shaft gear units are particularly suitable for conveyor technology applications. All 11 sizes can be fitted with either a hollow shaft, output shaft, mounting flange or shrink disc. The ratio range of gear unit sizes F04 to F07 can be extended by a third, from size F08 by a fourth and at size F15 even with a fifth gear stage.
