啮合齿向误差对齿轮承载能力的影响

The Effect of Gear Mesh Error on Gear Loading Capacity

提出了一种啮合齿向误差计算方法，即将齿轮轴线倾角分成两个分量，分别计算啮合齿向误差，然后按方向进行叠加；用这种方法可以分析多种外界因素对齿轮啮合的影响，如箱体变形、轴端受力、轴线挠曲等；可以形成适当的空负荷啮合齿向误差，使工作状态下啮合齿向误差得到补偿；可以根据齿轮接触情况验算齿轮强度；在不增加啮合齿向误差的前提下，合理给定支承平行度要求。

The authors have come up with a method for calculating gear mesh error. Under this method the gear axial inclination angle is divided into two components with the gear mesh error being calculated separately and then added up as per direction. This makes it possible to analyze the effect on gear mesh of such factors as gear box deformation, axial end loading and axial deflection, etc. A proper no load gear mesh error may be generated to compensate gear mesh error under operating conditions. It is also feasible to verify gear strength on the basis of gear contact conditions. Under the precondition of an absence of increase in gear mesh error a rational support parallelism can be set.
