| 摘 要： | 介绍了一种使用普通电机,行星减速机构和液压系统组成的新型调速装置.通过液压马达的速度调节,可方便进行输出转速的调节.对输出转速和输出扭矩进行了理论分析,在高转速输出时,调速装置以机械传动为主,输出高速小扭矩,获得大功率高效率的传动.在低转速输出时,利用液压系统的反馈作用,产生低速大扭矩的输出,以满足主机在恶劣作业工况下的要求.最后对电机和液压系统的功率匹配值进行了推荐,并对液压系统中的液压元件的参数进行了计算分析. |

| Abstract: | A novel speed governor with the normal electrical motor,planetary gear reduction mechanism and hydraulic system is primarily introduced.Afterwards,the output rotary speed is conveniently governed using the hydraulic motor.Subsequently,the output rotary speeds and toques are theoretically analyzed.Under high-speed outputs,the mechanical transmission is applied for speed governors with high speed,low torque and high-power yet high-efficiency transmission.Under low-speed outputs,the hydraulic system is used for feedback with low speed and high torque to meet the tough working conditions to main engine.Consequently,the matching value between the electrical motor and hydraulic system is recommended,while the hydraulic component parameters are calculated and analyzed. |
| Keywords: | stepless speed governing electrical motor closed circuit system planetary gear reduction mechanism feedback |
