Abstract

Angular misalignment error is a prevalent issue in gear transmission systems, often leading to adverse effects such as uneven load distribution and the induction of vibrations. Tooth modification methods are commonly utilized to optimize load distribution and mitigate vibrations in gear systems experiencing angular misalignment. However, these methods may exhibit degradation when gear systems operate outside the supposed specified range of working conditions. In this paper, we introduce a new tunable eccentric bearing block (TEBB) mechanism specifically designed for vibration control in spur gear system with angular misalignment errors. The spatial position variation of bearing rotation axis, time varying mesh stiffness (TVMS) and contact line length are analyzed with the proposed TEBB and angular misalignment. Subsequently, a 10-degree-of-freedom (DOF) dynamic model of spur gear system is established to investigate the effects of the TEBB on dynamic responses considering angular misalignment. The findings reveal that the proposed TEBB offers superior performance in vibration control compared to the traditional tooth crown modification method. Furthermore, a back-to-back experimental setup is constructed to validate the effectiveness of the proposed TEBB. The results demonstrate that the proposed TEBB mechanism is indeed beneficial for vibration control in spur gear system with angular misalignment error.

角对中误差直齿轮系统振动控制的可调偏心轴承座机构设计与分析

角度不对准误差是齿轮传动系统中一个普遍存在的问题，经常导致不利影响，如负载分布不均匀和振动的诱导。齿形修正方法通常用于优化负载分布和减轻振动在齿轮系统经历角度失调。然而，当齿轮系统在假定的指定工作条件范围之外运行时，这些方法可能会出现退化。本文介绍了一种新型的可调偏心轴承座（TEBB）机构，该机构是专门为具有角对中误差的直齿轮系统振动控制而设计的。利用提出的TEBB和角不对中分析了轴承旋转轴的空间位置变化、时变啮合刚度和接触线长度。在此基础上，建立了直齿齿轮系统的10自由度动力学模型，研究了考虑角度不对准的直齿齿轮对系统动态响应的影响。结果表明，与传统的牙冠修复方法相比，所提出的TEBB在振动控制方面具有更好的性能。此外，建立了一个背靠背实验装置来验证所提出的TEBB的有效性。结果表明，所提出的TEBB机构对存在角不对中误差的直齿齿轮系统的振动控制确实是有益的。
