汽轮机转子动叶围带滚压机的设计与实践

Design and Development of Rolling Machine for Rotor Blade Shroud

针对公司汽轮机转子动叶围带的产出供应不足问题,指出铸钢动叶围带制造工艺的局限性是影响动叶围带生产效率的关键原因。根据动叶围带的特点,设计了一台简单实用的动叶围带滚压机,通过结构改进提高了设备的性能。经过实际使用,证明滚压的动叶围带成本低、质量可靠、性能稳定,完全可以取代铸钢动叶围带。

The thesis briefly analyzes the advantages and disadvantages between rolled shroud and casting shroud. It introduces the design and development of a set of roiling machine for rotor rotating blade shroud. It＇s been proved that the rotating blade shrouds which rolled by the rolling machine have stable properties, high quality and low cost.
