Abstract


In this paper there are presented theoretical and experimental researches on the load capacity of a cone tightening assembly. Conical tightening assemblies are used in the automotive industry to assemble shaft pulley assemblies, such as assembling the pulley on the crankshaft or on the shaft of the current generator. It is necessary to test the theoretical and experimental maximum torque for different axial forces in order to ensure the proper operation of the designed assembly. The torque transmitted by the assembly is obtained in the first step by analysis with finite elements in ANSYS, and is necessary to be verified by experimental measurement. In the second step, the load capacity of this assembly, which is the dependence of the torque transmitted on the axial force of the assembly, is examined experimentally. For this purpose, an experimental test bench has been created to measure the axial force and torsion, by means of strain gauges transducers and a high performance measurement system. The results obtained by numerical simulation in ANSYS and by experimental research validate the prescribed specifications for designing these assemblies, commonly found in machine manufacturing.
