摘　　要：采用混合动力技术是当代挖掘机研究发展的趋势。针对液电混合动力挖掘机的特点,研制了一种带内置制动器的电动回转驱动器,与桂柳工922D型混合动力挖掘机配套使用。运行结果表明:挖掘机回转平稳可靠、满足实地作业要求。电动回转驱动器的研制建立在广泛收集国内外相关技术文献、专利文献和信息的基础之上,特别对进口配套的回转驱动器在实际运行中出现的故障及主要失效原因作了专题考察和技术分析,明晰了回转驱动器的研发目标和技术要点,在行星减速器和内置制动器一体化集成结构的设计与计算、制造工艺及工装上取得多项技术突破与创新,为混合动力挖掘机回转工作平台的驱动与制动提供了有效的解决方案。Hybrid-powered technology is the trend of excavator development. According to the characteristics of liquid electrichybrid excavators, electric rotary driver with inner braker matches Liugong Model 922D dynamic excavator. The new excavator slewing is stable and reliable, and meets the field operation requirement. The development of the electric rotary driver is based on the extensive collection of technological references, patent document and information at home and abroad. After thematic investigations and technical analysis are made on the faults and the failure in actual running especially for the imported corollary rotary driver, the development and technique essentials of the rotary driver come to clarity. Several technical breakthroughs and innovations are made in the design and calculation of the integration structure for the planet reducer and the inner brake, manufacturing process and frock. This can provide an effective solution to the driving and braking of the dynam- ic excavator rotary working platform.
