Helical gear unit, G type

The high-speed gear units from RENK-MAAG GmbH are designed and constructed according to the latest findings and methods of gear unit technology. RENK-MAAG GmbH high-speed gear units can transmit a power of up to 180 MW and serve as the key component of an energy production system or as drive units for compressors or pumps (such as those used for air separation, the supply of gas turbines, gas compression, in the chemical and petrochemical industries, the refining of raw materials, steelworks, and in the process industry).

The pinions of the helical gear units with horizontally, vertically, or diagonally divided housings rotate at up to 63,000 rpm. The gear unit housing and the customer’s connecting dimensions can either conform to RENK’s standards or be adapted completely to the requirements of the customer. This is of crucial importance when it comes to replacing third-party products in particular.

Gear units from RENK-MAAG GmbH can be propelled by gas turbines, steam turbines, synchronous or asynchronous electric engines, or even by expanders (axial or radial turbines). An energy recovery system can even be implemented in conjunction with a synchronous clutch coupling from RENK-MAAG GmbH. In this case, a synchronous electric engine, for example, propels a compressor and an expander turbine feeds process energy back into the system via the MS clutch.
