Recently, Nanjing Gaojing Marine Equipment Co., Ltd., a wholly-owned subsidiary of China High Speed ​​Transmission Equipment Group Co., Ltd., which settled in Jiangning Science Park, successfully developed the marine lateral thruster with the largest power and the largest blade diameter in China. The successful development of this propeller has filled the gap in the field of large-scale lateral propellers in China, breaking the market monopoly of foreign manufacturers on large-scale side thrust products.
The power of the propeller motor is 2200KW, the diameter of the blade is 2750mm, the diameter of the large end of the spiral bevel gear is 1075mm, and the power and blade diameter are the largest in China. In the R&D and design of the product, the company introduced foreign advanced design software for product strength design, bearing life and gear shape calculation, which improved the reliability and advancement of the product and effectively shortened the product development cycle. At the same time, in the design, attention is paid to improving the hydrodynamic performance, optimizing the gearbox line type and reasonable bearing arrangement, so that the propulsion efficiency and service life of the product are greatly improved, and the vibration and noise of the whole system are greatly reduced.
