About WELTER zahnrad
WELTER zahnrad GmbH is a manufacturer of gearings and drive elements. Its manufacturing spectrum includes bevel gears with straight, spiral and curved toothing, produced as hard skiving to Klingelnberg HPG, by bevel gear grinding to Klingelnberg/Gleason, or by free-form milling in soft and hard machining. In the field of cylindrical gears, the company manufactures pinions, pinion shafts, gears, ring gears as well as numerous special parts, including internal gearings, herringbone gearings, worm gear sets, crown gears, Hirth and face gearings, elliptical gears and bevel gear sets with very small shaft angles. In addition, WELTER uses its experience in free-form milling to manufacture technical cams. The products are used, among other things, in locomotive drives, gearboxes for tunnel boring machines and turbo gearboxes. In addition to manufacturing, the company offers development and design services.
