The successful development of the first 2.5MW wind power gearbox of CSR

Recently, the first 2.5MW wind turbine gearbox of China South Locomotive was assembled and accepted, and sent to the wind farm for prototype testing, indicating that CSR has the design and manufacturing capabilities of a 2.5MW wind power gearbox.

The 2.5MW wind power gearbox project was designed and developed by CSR Qishuyan Locomotive & Rolling Stock Research Institute Co., Ltd. (referred to as the China South Qishu Qishu Institute). The project started in October 2010 and lasted six months. It successfully completed the design, manufacture and testing, passed a third-party audit, and obtained the German “GL Classification Society” certification. In the process of project advancement, CSR Qishuyan has fully exploited the superiority of material technology research and development accumulated in more than 50 years, as well as multidisciplinary professional advantages such as casting, heat treatment, mechanical processing, welding and surface treatment, and overcame design, materials, large-scale casting and Technical difficulties in processing and assembly, etc. Product technical indicators have reached the international advanced level.

It is reported that gearboxes are one of the key components of wind turbines, and they are technically difficult and demanding, and are crucial to the normal operation of generator sets. The successful development of CSR 2.5MW wind power gearbox is an important step taken by CSR in the wind power industry layout, and it is an important symbol for CSR to further master the core technology of wind turbines and enhance the core competitiveness of products.
