摘　　要：垂直螺旋输送机在长时间输送煤料后,螺旋叶片会产生严重的物料磨损。现有磨损模型无法直接对垂直螺旋输送机上螺旋叶片的使用寿命进行预测。因此,基于Archard模型并采用连续介质假设的方法建立了螺旋叶片磨损模型。该螺旋叶片磨损模型可用于预测在不同工况下垂直螺旋输送机螺旋叶片的磨损,比如不同转速、填充率和螺距。可为螺旋叶片寿命的预测提供可靠的计算模型。After the long-term transportation of coal materials, the screw flight on the vertical screw conveyor will be seriously worn by the materials. The existing wear models can not directly predict the service life of screw flight on vertical screw conveyor. Therefore, based on Archard model, the wear model of screw flight was established by using continuous medium hypothesis. The wear model of screw flight can be used to predict the wear of screw flight of vertical screw conveyor under different working conditions, such as different speed, filling rate and pitch. It provides a reliable calculation model for the life prediction of screw flight.
