This article presents the results of measurements of a belt transmission with a poly-V belt 5PK, most often used in the industry, especially in industrial drives, agricultural machines and in the automotive industry. The main goal of the works was to obtain the dependence of the belt slip value on the measured, relatively high values of resistance torque. For this purpose, a series of measurements were made using a specialised research stand consisting of two alternating current motors and attached pulleys. It considered four cases of the value of the belt pre-tensioning force. In each of the cases, while making the measurements, the resistance of the passive pulley was increased, resulting in increasing values of belt slip. Finally, the achieved courses were approximated. The obtained results will be used to develop empirical models of friction at the belt-pulley interface. They can also be useful for belt manufacturers to make better belts, especially those subjected to higher loads.
