【摘要】 渐开线齿轮由于啮合性能好、传动效率高、加工成本低，广泛应用在各种机械传动领域中。在渐开线齿轮泵中，由于内部流体体积的变化，渐开线齿轮表面会受到不断变化的流体压力，较强的流体压力会使齿面发生变形，导致齿轮在运行过程中不能按照理想的啮合线进行啮合，从而影响齿轮泵的寿命与稳定性。目前针对渐开线齿轮受力变形的研究大部分是对齿廓进行齿顶修形，减小啮入、啮出冲击，以及齿向鼓形修形，常规方法对齿轮泵性能和寿命提升幅度较小，无法满足齿轮泵性能要求。因此，为了提升齿轮啮合性能和使用寿命，在考虑齿面流体压力的基础上，建立齿面变形与表面受力的关系，将变形补偿到齿廓上，提升齿轮的啮合性能，解决齿轮泵性能低、寿命短等问题。该性能改进方法对齿轮泵性能提升具有理论指导意义。更多还原

【Abstract】 The involute gear was widely used in various mechanical transmission fields because of its good meshing performance, high transmission efficiency and low processing costs. In the involute gear pump, due to the change of internal fluid volume, the surface of the involute gear was subject to changing fluid pressure, and the strong fluid pressure would deform the tooth surface, which resulted in that the gear could not be engaged according to the ideal line of engagement during operation, thus affected the life and stability of the gear pump. At present, most of the studies on the force deformation of involute gears were to modify the tooth top of the tooth profile to reduce the impact of biting in and out, and to modify the tooth drum shape. The conventional methods had a small improvement in the performance and life of the gear pump, which could not meet the performance requirements of the gear pump. Therefore, in order to improve gear meshing performance and service life, it was established that the relationship between tooth surface deformation and surface force on the basis of considering the fluid pressure of the tooth surface, and we compensated the deformation to the tooth profile to improve gear meshing performance and solve the problems of low performance and short life of the gear pump. The performance improvement method had theoretical guiding significance for improving gear pump performance.更多还原
