Turbine Couplings

Turbine coupling is a specialized product developed by Rokee for matching couplings of steam turbine units. It has been serialized and adapted to steam turbine units of different powers and speeds. After years of verification, the product quality is reliable, meets the operation environment requirements of turbine units and has long service life.

The operating environment of the steam turbine coupling is sometimes very harsh, especially the high temperature and humidity environment and high speed requirements have special manufacturing process requirements for couplings. Besides, the coupling structure cannot be sealed and can only be lubricated openly, thus requiring more special design. Rokee cleverly solved all the problems of structure and manufacturing process, becoming the only professional company in the Chinese market that can produce better substitutes for imported products. Furthermore, through R&D of such type of products, we have mastered the core development index and technology of high-performance drum gear coupling, to allow Rokee's gear coupling technology to stand out further.

In the field of steam turbine transmission systems, our excellent products outperformed the imported products in some occasions, saving more costs and time for customers. The drum gear shafts we designed are fast and silent, and every component has passed strict balance test, enjoying long life and excellent performance.

The detailed size of each gear has been carefully and rigorously optimized, and the grinding process has achieved a precision of 6 levels.

With open lubrication, the coupling skillfully distribute the lubrication medium to all parts needing lubrication through its own rotation, providing reliable guarantee for operation performance and product life.

The special metal diaphragm coupling designed by us for high-speed and low-wind resistance steam turbine units is also the product that we are proud of and has become a better choice among domestic units.

The patented bolt anti-loosening design ensures that our high-speed couplings are worry-free to use.

Our technical team will continue to work on the improvement and optimization of the series of couplings. We expect to make more contributions to China's steam turbine units and nuclear power fields with better system performance and longer service life.
