摘要
为明晰齿轮马达密闭介质的制动机理及其制动性能的最大化措施,从齿轮副的啮合过程出发,由马达内介质作用的液压转矩等于马达外的负载转矩,推导出负载驱动转速的定量公式,并就制动性能最大化对齿形参数执行最优化设计。结果表明:啮合点的位置不同,负载驱动转速也不同,其中,最小困油位置处的最高,节点啮合处的最低;齿形参数对负载驱动转速的影响很大,案例优化前后的制动性能提高了31.2%~46.1%;负载转矩与马达内客观存在的泄漏途径为驱动转速产生的外因与内因,齿轮较小的宽径比和齿顶高系数能有效控制马达内泄漏等。研究成果为高质量齿轮马达的进一步研究与开发,提供一定的理论依据。
In order to clarify braking mechanism of closed working medium in gear motor and measures to maximize its braking performance,from meshing process of motor gear pair,and internal generated hydraulic torque by closed working medium being equal to external load torque,a quantitative formula for calculating driven revolving-speed by external load torque is derived;then a optimum design of tooth shape parameters is carried out for maximum braking performance of gear motor.All results show that driven revolving-speed varies with different meshing point position,among them,which is the highest at the least trapped-oil position,and the lowest at the pitch meshing point;tooth profile parameters have a great influence on the driven revolving-speed,before and after a optimized case,the braking performance is improved by from 31.2%to 46.1%;external load torque and objective leakage path in gear motor are main external and internal causes of driven revolving-speed,small width-diameter ratio and addendum coefficient of gear can effectively control internal leakage,etc.All research results can provide some theoretical basis for further high quality research and development of gear motor.
