摘要

不同齿数的双圆弧齿轮啮合传动时,由于齿宽不相同,轮齿在受力时的弯曲变形也不相同,则轮齿每个啮合点处的接触应力不相同。建立双圆弧齿轮啮合点接触力的数学模型,并根据弹性力学和材料力学计算出了轮齿弯曲刚度,通过实例计算获得了不同齿数、模数及重合度时双圆弧齿轮各啮合点处的接触力。研究结果将为双圆弧齿轮齿廓修形及提高齿轮承载能力提供依据。

Abstract

The contact stress in different meshing point is not the same of double circular arc gear due to its different teeth numbers,tooth width and tooth bending deformation. A meshing point contact force mathematical model of double circular arc gear is established,the gear tooth bend stiffness is calculated according to mechanics of materials and the theory of elasticity. The numerical example is calculated to obtain the contact force in different meshing point of double circular arc gear of different tooth number,modulus and contact ratio.The basis for the tooth profile modification and improving the gear load capacity of double circular arc gear is provided by the research result.
