机械齿轮故障机理以及特性分析

Analysis of the Fault Mechanism and Characteristic of Mechanical Gear

从传动理论的角度分析机械齿轮出现故障的机理,从齿轮损坏、碰撞自振、齿面破损、齿面点蚀4个方面阐述齿轮故障的主要特征,并从干预齿轮啮合振动、齿轮损坏的预防、落实日常维护3个方面介绍齿轮故障的预防措施。

This paper analyzes the failure mechanism of mechanical gear from the angle of transmission theory,expounds the main characteristics of gear fault from four aspects of gear damage,collision self-vibration,gear surface breakage and gear surface pitting.And the preventive measures for gear fault are introduced from three aspects,including the prevention of gear meshing vibration,prevention of gear damage and the implementation of daily maintenance of the gear.
