摘　　要：针对非标齿轮设计参数协同关系展开研究,基于齿轮啮合原理,建立非标齿轮过渡圆角半径与齿轮压力角关系方程式,分别研究非标齿轮压力角、过渡圆角半径以及齿顶高系数对齿根弯曲应力的作用机理,获得非标齿轮压力角、刀具过渡圆角半径及齿顶高系数对承载能力的影响关系,提出高齿根弯曲强度非标齿轮参数协调关系曲线及协同设计方法,并通过仿真分析验证了理论研究的正确性,为要求高齿根弯曲强度的非标齿轮设计参数选取提供指导。The collaborative relationship of the design parameters of the nonstandard spur gears for improving the bending strength is studied,Based on the engagement theory,the equation of the relationship between the fillet radius and the pressure angle is established. The mechanism of action of the pressure angle,the fillet radius and the addendum coefficient to the bending strength are investigated. And the way that how the pressure angle,the fillet radius and the addendum coefficient effect the bending strength is achieved. The coordinated curves of the gear parameters and the collaborative design are proposed for the higher bending strength of nonstandard spur gears and the correctness of the study is verified by simulation analysis,the reference can be provided for the parameter design of the non- standard gear.
