Industrial Gear Units

RENK develops and builds industrial gear units for almost any field of application. In addition to the design versions listed in the tables, the RENK product range includes one-off special-purpose gear units for power generation, cement production, rubber and plastic industries, water and wind power stations, transport and conveyor equipment, and open-pit mining applications.


High speed

High Speed Gearbox

For many decades, RENK has been a leading manufacturer of high-speed gearboxes and enjoys an excellent reputation with their series TS, TB, TL, TNA and TNB. Supported by up-to-date CAD-systems and computer controlled production, products of superior quality are built and delivered worldwide.
Hydro power

Water Power Gearbox

RENK speed increaser with integral turbine bearings. Water power gear units form an integral part of the turbine. They have to be designed in close cooperation with the turbine manufacturer. Especially the gear units low speed shaft requires utmost attention. Low head sites usually can only be exploited by the use of Kaplan Turbines. The use of RENK water turbine gears will increase the overall efficiency from typically 96% to 98.3%

Wind Energy

Maximum reliability due to the optimal load distribution and slide bearing technology.
EQ-Gear® combines maximum power density with compact dimensions in a unique way.
Operating conditions with different combinations of speed and torque place high requirements on gearboxes in wind power. Special materials as well as innovative coating methods ensure an optimal operation – even at extremely high pressures and very low speeds. An intelligent planetary bearing system ensures a uniform load distribution in the respective operating conditions and optimizes the meshing contact of the gears. The intelligent planetary bearing system in connection with the use of five planets maximizes the power density.
The EQ-Gear® is suitable both for low and medium speed platform configurations in a coaxial design as well as for the highspeed drive train with an axial offset generator connection. In particular with the coaxial platform configuration, the wire required for the pitch control can easily be guided through the gearunit between the input shaft and output shaft. The unique wireless temperature monitoring ensures the remote maintenance of slide bearings as well as the optimized self-adjusting load distribution between the planetary stages. This results in an excellent overall system that is designed specifically for the drive train of the wind turbine: with a RENK coupling and a RENK condition monitoring system.
