新型金刚石链锯的链条受力分析

Force analysis for chain of new diamond chain saw

文章对用于大板切割新型金刚石链锯的链条张力进行了分析计算,由计算结果可知,新型金刚石链锯链条张力在试验装置条件下紧边张力为1705N,松边张力为1639N,且张力随着链轮直径的增加而减小;并由此计算并绘出了新型金刚石链锯链条围齿区整体受力分布图,由图可知,两轮结构下最大链条受力点为链条紧边最先与主动链轮啮合处。

In this paper,the strain of the chain of new diamond chain saw used for cutting stone is analyzed and calculated.The results show that under the experimental conditions,the strain of chain＇s tight side is 1705N,the loose side is 1639N,and strain is decreased with the chain wheels＇ diameter increasing.The force＇s distribution curve of the chain is also drawn.From the drawing we can found that the largest force point is the meshing point of chain＇s tight side with the driving wheel in the condition of two-wheel structure.
