摘　　要：主要探讨如何在有限的空间内提高重载齿轮箱的传动性能,延长齿轮箱的服役寿命。在不改变啮合齿轮副的传动特性情况下,经过齿根喷丸强化增加齿根许用弯曲应力值,通过改变齿轮副顶隙系数的情况下,降低齿轮弯曲应力值这两种方法提高齿轮抗冲击强度23%左右,极大提高重载齿轮箱齿轮副抗冲击载荷能力。It is mainly discussed how to improve the transmission performance of heavy-duty gearboxes and extend the service life of gearboxes in limited space.Without changing the transmission characteristics of the meshing gear pair,after tooth root shot peening to increase the permissible bending stress value of the tooth root,by changing the top clearance coefficient of the gear pair,reduce the bending stress value of the gear,these two methods to improve the impact strength of the gear by about 23%.Greatly improve the heavy-duty gearbox gear vice impact load resistance.
