Founded as an ironworks

The company is named Königliches Berg- und Hüttenwerk (Royal Mine and Steel Works)

Production of agricultural machinery (toothed gear units, motorized road rollers, diesel locomotives, ballast excavators)

The company is renamed Bayerische Berg-, Hütten- und Salzwerke AG, Zweigniederlassung Hüttenwerk Sonthofen (Bavarian Mine, Steel and Salt Works Company, Sonthofen Steel Works)

Production of planetary gear units begins with the takeover of Stoeckicht—the start of precision mechanical engineering at BHS

Development of a double helical-geared Stoeckicht planetary gear unit for steam turbine drives

The first BHS parallel shaft gear unit

BHS manufactures gear units for the first five of Germany’s post-war Cologne-class frigates

A range of high-speed tooth couplings is developed

The first turning gear units to use the swivelling pinion principle are manufactured

The first of 20 planetary gear units with an internal gear diameter of 2.5 m (8 ft) is delivered for hydroelectric power stations on the Moselle river

High-speed parallel shaft gear units with reference speeds of >100 m/s (>328 ft/s) for gas turbine drives and transmission outputs of 18 MW are delivered for the first time

The first hydrostatically-controlled planetary gear unit (speed-modulating gearbox) for turbine compressors is developed

Starting gear units and adjustable mechanisms, known as multi-pinion gearboxes, are developed for gas turbines

Stoeckicht is taken over, together with all its patents

Multi-pinion gearboxes with integrated compressor stages

BHS acquires the turbo gear unit portfolio of Krupp, Essen

BHS licenses Cincinnati Gear, USA, to manufacture planetary gear units

The first thrust collar-type turbo parallel shaft gear unit is built

First turbo parallel shaft gear unit with an output of over 30 MW for gas turbine drive applications

The first of twelve gear units for class F122 frigates is delivered to the German navy

With an output of 47 MW, the most powerful turbo parallel shaft gear unit yet seen for gas turbine drives is built

The first turbo parallel shaft gear unit with a reference speed of 200 m/s (656 ft/s) is delivered

High-speed supercritical multi-pinion gearboxes in thrust cone form are developed for integrated multi-stage compressors

Spur-geared compact planetary gear units are developed for integrated single-stage compressors

Turbo parallel shaft gear units for gas turbines with an output of 51 MW

The first orders for the new compact planetary gear unit are received, and trials are completed successfully

TWINTORS diaphragm couplings are developed, tested and built

Merger with gear unit manufacturers Voith Heidenheim to form BHS–Voith Getriebetechnik GmbH, based in Sonthofen

The state-run company BHS AG is taken over completely by SKW Trostberg AG

The Bavarian state sells BHS to SKW Trostberg (VIAG AG)

First order for gear units for motor-driven LNG compressors

First orders for gas turbine gear units transmitting 75 MW

BHS–Voith-Getriebetechnik GmbH is wound up. BHS AG buys the Voith part back and integrates the gear unit division back into the Sonthofen works

BHS’s Sonthofen plant is broken up. The gear unit division is taken over by the Cincinnati Gear Company (USA) and is renamed BHS Cincinnati Getriebetechnik GmbH

Marine gear unit construction ceases on 31 December

Lothar Hennauer and Dieter Groher are appointed as directors

Delivery of WGD5-330, the biggest integral gear unit built so far for PTA production (weight 42 t, peripheral speed >170 m/s (>557 ft/s), output 28.4 MW)

Munich investment company EquiVest KG joins forces with the management to acquire the shares of BHS Cincinnati Getriebetechnik GmbH. The company is renamed BHS Getriebe GmbH

BHS Getriebe Inc. (USA) and BHS Japan are founded

Equity investment group Halder and BHS management take over the shares of BHS Getriebe GmbH from EquiVest GmbH, Munich

Voith Turbo AG takes over 100% of the shares of BHS Getriebe GmbH. The company is renamed Voith Turbo BHS Getriebe GmbH
