摘要

为研究动载荷对准双曲面齿轮齿根弯曲应力的影响,使用电测法对驱动桥从动锥齿轮齿根弯曲应力进行了静态和动态测试,并对比有限元计算结果进行了分析。静态测试分析结果表明,齿轮啮合过程中,齿面接触由大端过渡到小端,啮入过程正车面齿根受拉,啮出过程受压,应力值与有限元计算结果基本一致。动态测试分析结果表明,随着齿轮转速升高,齿根最大应力的平均值、振幅都逐渐增加。此测试方法可靠易行,可用于齿轮相关的可靠性研究。

Abstract

In order to study the effect of dynamic load on the tooth root bending stress of hypoid gears,both static and dynamic test of hypoid gear bending stress of the driving axle are carried out by using electromotive strain method,which are compared and analyzed with results from finite element simulation. The static test shows that the tooth contact position is from the big side to small. The tooth root is under the application of tensile stress when the contact is begin while under compressive stress when the contact is finish. The stress value is consistent with the results of finite element calculation. The dynamic test shows that the mean value and amplitude of the maximum bending stress increased gradually with the increase of gear speed. This method is reliable and can be used in the reliability research on gear.
