On August 18, the GH270 high-speed gearbox—self-developed and prototype-produced by the company for a research institute in northern China—has been shipped to the customer in Beijing.
The GH270 speed increaser features a single-stage, parallel-shaft, horizontal offset-center design, with a rated input power of 800 kW. Its high-speed shaft is designed for a rated speed of 10,500 rpm, and the gear line speed can reach up to 70 m/s. While this product boasts a relatively simple overall structure, it demands meticulous attention to design details, precise machining of components, and rigorous control throughout the entire assembly process. Test bench evaluations have demonstrated that the speed increaser excels in key performance metrics, including vibration levels, noise emissions, and bearing temperatures—earning high praise from users.
