摘　　要：为了开发研制出一种低速小型机械调速器,论证基于接触摩擦的调速原理,通过建立调速器的实体模型检验设计、加工的可行性,对其调速特性进行仿真分析,调整重要零部件的规格尺寸及材料,检验调速性能的可靠性及合理性,最后试制样机进行速度试验,并验证调速器的整体性能.结果表明,所探讨的调速器能够有效消除干扰对速度的影响,通过调节弹簧力得到较为精确的低速稳态转速;综合考虑加工装配误差、润滑不均及现场使用条件等不良因素对调速性能所造成的负面影响,调速器可以满足低速运动状态下控制速度,使其稳定在一定范围之内的使用要求;可以应用于低速运动以及高压环境下或存在电磁干扰以及严禁流体泄漏等不便于使用电气控制、流体控制的调速环境之中.In order to develop small mechanical low speed governor, firstly, the paper gives reasoning for contact friction principle of speed control. And then, solid model is established for checking feasibility of design and machining, and part size and material adjusting method is used for speed control simulation and analysis to checking reliability and rationality. Finally, sample machine is made for speed testing and whole capability validating. Result shows that the governor can effectively eliminate effect from interference, and the control of spring force can get more accurate low steady speed, and the governor can meet speed controlling demand at low speed state when adverse factors is considering, such as error of assembly machining and bad lubricate and bad using environment. The governor can be used in electric or fluid control environment with low speed or high voltage or electromagnetic interference or no fluid leaking demand.
