多轴齿形链系统动载荷特性的研究

Study on Dynamic Load Characteristic of Multi Axis Silent Chain System

载荷(工况)系数是链传动系统设计的重要原始输入之一,是直接关系到链条承载能力的设计变量,特别是对于正时齿形链系统,链板厚度或链板片数均与此相关。通过某款发动机正时链系统设计实例,在忽略曲轴扭振以及发动机气缸爆炸做功的前提下,定性分析了正时链系统的载荷特性,并通过缸盖反拖系统试验台静拖动转矩、动载转矩的测试,提出了正时齿形链系统不同转速条件下的载荷(工况)系数及其确定方法,对相关多轴、高速齿形链系统设计具有重要参考价值。

The load （working condition） coefficient is one of the important original inputs in the design of chain transmission system, it is directly related to design variables of the chain bearing the timing silent chain system, the chain plate thickness or number are all related to it. capacity, especially for Through a engine timing chain system design, ignoring the torsional vibration and engine cylinder to work, the load characteristics of the timing silent chain system are analyzed qualitatively. By using the cylinder head anti drag system test bench, through static and dynamic load torque test, the load coefficient and the method of determining under different speed conditions of the timing silent chain system are proposed, which is of great reference value to the design of the multi axis and high speed silent chain system.
