摘要
齿轮间隙是影响汽油机平衡轴可靠性的关键因素。本文基于控制变量法研究了平衡轴齿轮间隙的测量特性,并对平衡轴夹爪橡胶材料、平衡轴弹簧压紧力与coast力矩的匹配关系和平衡轴螺栓的拧紧工艺进行了优化。结果表明:齿轮间隙的合格率主要与平衡轴夹爪橡胶材料、平衡轴压紧力与coast力矩匹配关系和平衡轴螺栓的拧紧工艺有关,通过优化平衡轴夹爪橡胶材料,齿轮间隙的合格率从95.09%提升至97.11%,优化平衡轴压紧力与coast力矩匹配关系后,合格率提升了1.41%,进一步优化螺栓的拧紧工艺后,其合格率提升了1.26%,最终达到了99.78%,有效解决平衡轴齿轮间隙测试不合格的问题。
Gear clearance is a key factor affecting the reliability of gasoline engine balance shafts.This article studies the measurement characteristics of the gear clearance of the balance shaft based on the control single variable method,and optimizes the matching relationship between the balance shaft clamp,the balance shaft compression force,and the coast torque,as well as the tightening process of the balance shaft bolts.The results indicate that the qualification rate of gear clearance is mainly related to the matching relationship between the clamping jaws of the balance shaft,the compression force of the balance shaft and the coast torque,and the tightening process of the balance shaft bolts.By optimizing the rubber material of the balance shaft gripper,the qualification rate of gear clearance increased from 95.09%to 97.11%.After optimizing the matching relationship between the balance shaft compression force and the coast torque,the qualification rate increased by 1.41%,and after further optimizing the bolt tightening process,the qualification rate increased by 1.26%,ultimately reaching 99.78%,effectively solving the problem of unqualified balance shaft gear clearance testing.
