为明晰齿轮马达困油对输出转矩转速的影响机理及其脉动最小化策略,在马达困油特性分析的基础上,从双齿啮合与单齿啮合两个方面,建立了输出转矩的分段计算式;由注入介质的压差能等于马达输出的动力能,建立了输出转速的分段计算式;根据理论判断出的最大最小转矩位置,给出脉动最小化的轴向双副结构方案。结果表明,齿轮马达的困油现象相对温和,常规双矩形卸荷槽即能满足卸荷要求;齿数为10下的转矩、转速的脉动系数分别为0.26、0.3,齿数为其影响的最大因素;马达齿轮的空转有利于采用轴向错位啮合的双齿轮副构造来实现输出脉动的最小化,改善率分别为61.5%、65.3%。得出双副能实现少齿数的轻量化和超低脉动的目的,为高质量齿轮马达的进一步研发提供了依据。
In order to clarify the influence mechanism of trapped-oil on output torque and speed of gear motor and its ripple minimization strategy,from its special trapped-oil characteristics analysis and two aspects of double tooth meshing and single tooth meshing,the proprietary calculation formula between partitions of output torque is established. Then from pressure difference energy of injected medium is equal to power energy of motor output,the proprietary calculation formula between partitions of output speed is established. Finally,according to the special meshing position of maximum and minimum torque,the axial double-pairs structure with minimum ripple is given. The results show that,trapped-oil phenomenon of gear motor is relatively mild,conventional double rectangular relief groove is suitable for relieving trapped-oil pressure. The tooth number is the biggest factor affecting torque and speed ripple,the ripple coefficients of torque and speed under the tooth number of 10 are 0.26 and 0.3,the idling motor gear is advantageous to double-pairs structure to minimize output torque and speed ripple,and following improvement rates are 61.5% and 65.3%,respectively,etc. It is concluded that lightweight through fewer teeth and ultra-low ripple through axis double-pairs with dislocation meshing can be perfectly fulfilled,which provides the basis for the further research and development of high quality gear motor.
