Capability Research On Friction With Meshing Composite Belt

This paper established the mathematical model of friction and mesh belt using for pumping unit, systematically analyzed the characteristics of friction and mesh composite belt and the relationship between the transmission power and the friction coefficient, initial tension, wrap angle and the meshing teeth number for static performance analysis and testing. Put forward a test method for friction coefficient of belt, and conduct dynamic and static friction coefficient test with different roughness of belt wheel. It analyzed stress distribution of friction and mesh composite belt in the transmission process based on multi-body dynamics simulation software Recurdyn, which provided a feasible method for optimization of tooth structure size. This paper systematically studied influence of different tension force on friction and mesh composite belt slip rate, and field tested the the friction and mesh composite belt in the pumping unit, and the test results showed that the service life of this belt improved at least3times compared with transmitte the narrow v-belt with obvious energy saving effect. Design the NC electric closed friction and mesh composite belt performance, and used finite element analysis software solidworks simulation to analyze the shaft system of test-bed for optimization design.
