摘要
为测试滚子链的耐久性、使用寿命等性能,基于功率流封闭原理,为滚子链条磨损跑合试验设计了一套自动试验台。采用链轮错齿法,通过计算机控制张紧及夹持装置,对被试链条和陪试链条进行转矩加载,实现试验系统功率流封闭。为实现该试验台自动张紧和夹持功能,设计了液压及计算机测控系统,为满足不同型号链条的试验条件,对所需张紧油缸和夹持油缸进行了设计选型。通过零件加工和购买所需元件,搭建了试验台样机,并利用其对滚子链进行磨损跑合试验,结果表明,其能满足不同型号的滚子链试验条件,且能耗低,运行可靠。
In order to test the durability,service life and other properties of roller chain,based on the principle of closed power flow,an automatic test-bed is designed for testing the wear running-in of roller chain.To enable the power flow closure of the test system,the tension and clamping device is controlled by computer and the sprocket staggered teeth method is used for loading torque to the test chain and the accompanying test chain.The hydraulic and computer control systems are designed to realize the automatic tension and clamping function of the test-bed.The design and selection of tensioning cylinder and clamping cylinder are also carried out,so that the test-bed can meet the test conditions of different types of chains.The prototype test-bed is built by processing and purchasing required components.The wear running-in test of the roller chain is carried out by using the prototype.The results show that the prototype can meet the test conditions of different types of roller chains with low energy consumption and reliable operation.
