Gear wheels have been used in their simplest form for millennia to translate forces and convert energy into motion. Today, gear wheels play a vital role in the powertrains of machines and vehicles. The quality of gearing must be ensured for it to do its job with minimal loss or wear and tear. Quality is the top priority at Zahnradfabrik Wittmann GmbH. Dr. Oliver Mager, a senior executive in the company, emphasizes that “orders from our customers are not one-way streets. We are interested in long-term partnerships.” Wittmann’s customers come from a wide range of industries: gear manufacturing, mechanical engineering, special equipment construction, railway and energy technology, and wind turbines. As a contract gear manufacturer, the company produces straight and slanted-tooth spur gears, bevel gears, chain wheels, toothed-belt gears and pinion shafts from module 1 to module 36. Ninety percent of the batches have between 10 and 100 pieces. Occasionally, the company is called on to deliver single parts, prototypes and serial orders with 1000-10,000 parts. Single parts and entire batches are inspected. The gearing is subject to extreme demands, which is reflected in the requirements of DIN accuracy class 6 and higher.
