Abstract
The rotation resistance of mining rollers is a key factor affecting the energy efficiency of belt conveyors.Based on the analysis of the typical structural characteristics of mining rollers,this article systematically elaborates on the sources and composition of the rotational resistance,uses the superposition mechanism of bearing friction torque and seal friction torque as the basic framework for resistance calculation,and analyzes the influence law and mechanism of each factor on rotational resistance from the four dimensions of radial load,rotational speed,environment temperature and lubrication state.Research shows that the rotational resistance of mining rollers is a dynamic variable affected by strong coupling of working conditions.The increase in radial load and rotational speed will cause the resistance to rise monotonically.Temperature has a nonlinear effect by changing the viscosity of the grease.The time-varying degradation of the lubrication state driven by dust intrusion and high-humidity environment is the fundamental reason why the resistance continues to rise with service time.关键词
