摩擦带传动弹性滑动的动力学分析与试验 by 王旭东, 熊平原

“…Belts are widely applied to various machine.Elastic sliding is one of the characteristics of friction belt transmission,and it leads to inexact transmission ratio and transmission efficiency decreased of belt drive system.In order to investigate generation mechanism and influencing factor of elastic sliding of belt transmission,dynamic model and kinematics model of elastic deformation of belt are established.The section analysis method indicates that pulling force difference of tight side and loose side of belt is essential reason which brings elastic sliding of belts.Orthogonal tests of the effects initial tension of belt,pulley-belt speed and load on elastic sliding rate of belt are carried out by CQP-B drive test bed.The results show that 3-factor are almost equal importance on sliding rate of belt.The greater initial tension,the lower pulley speed and the smaller load,the less elastic sliding rate of belt,and vice versa.Based on the above research results,the foundation of theory and tests for design of belt transmission system is provided.…”
