The paper presents experimental studies of a drive system with a lead screw. The concept and the construction of the test stand, its parameters as well as the applied measuring apparatus and the scope of tests are described. Furthermore, a measuring system and a methodology of determining the loads on the nut of the lead screw, based on the strain gauge measurements, were developed. A special nut bracket with specimens for the strain gauge measurement was designed. Since the specimens are simultaneously subjected to tension, two plane bending and non–free torsion, a coefficient essential for determining the torque on the nut of the lead screw was estimated based on the finite element analysis of the nut bracket under complex load condition. The first part of experimental studies includes the determination of the efficiency of the lead screw and the efficiency of the typical drive system with the lead screw. The impact of the load level and the constant resistance in the system are included in the research. The second part of the study concerns the determination of dynamic load coefficients for various operating parameters. The efficiency of the lead screw and the efficiency of a typical drive system with the lead screw as well as the dynamic factors at start–up and braking were determined based on experimental tests referred to a ball screw.
