Improving the efficiency of the conveyor train: investigation of the impact of the drive station parameters on the traction force

Purpose. The purpose of this article is to analyze the impact of the drive station parameters on the traction force between the drive wheel tire and the longitudinal beam of the conveyor train trolley. Methods. The research was carried out using a dedicated test bench, which made it possible to determine the friction force depending on the different normal load and pressure in the tire of the drive wheel. The planning matrix before the experiment is provided, the most significant parameters are determined. Results. It was revealed that the significant parameters include the normal load, the tire pressure and the material of the longitudinal beam of the trolley. It was also revealed that with different coating materials, the traction force can increase or decrease with increasing of the tire pressure and the normal load on the drive wheel. Conclusion. In the course of experimental studies, empirical values were obtained of the traction force between the drive wheel and the side surface of the longitudinal beam of the trolley made of various materials. The maximum values of the traction force have been determined for certain materials over the entire range of pressures and normal loads.
