摘　　要：将不完全齿轮机构应用于高速重载电液振动冲击系统,系统包含多个大流量高速开关阀。系统采用周期时序信号控制液压回路切换,实现重载、高速振动冲击动作。为降低大流量高速开关阀的功率损耗,且能快速准确地切换,高速阀的先导控制器采用不完全齿轮机构。文中对传统不完全齿轮机构进行了改进和优化,使切换时高速阀换向可靠且平稳无冲击力,动作灵敏,保证液压缸控制阀组按设定时序、无相位偏差的切换动作,实现液压缸高频振动冲击动作。The high-speed electrohydraulic vibration impact system controls the switch of hydraulic circuit by periodic sequence signals,to achieve the heavy-load and high-speed vibration impact motion. Therefore it contains many high- speed on-off valves. In this paper,the intermittent gear mechanism is applied to high-speed electrohydraulic vibration impact as the controller of on-off valves. An improvement of traditional intermittent gear mechanism is proposed to ensure that the control valves ran switch smoothly without phase deviation at the predetennined order and time. The improved method aims at reducing the impact and enhancing the sensitivity of the high-speed on-off valves.
