THEORETICAL AND EXPERIMENTAL INVESTIGATION OF THIN-WALLED BEARING SHELL'S DESIGN PARAMETERS AND ASSEMBLY CONDITIONS ON THE HOLDING TORQUE INSIDE A HOUSING BORE OF A CONNECTING ROD

摘要

The aim of the work was the experimental and theoretical evaluation of the influence of the most important parameters determining the holding torque of a thin-walled bearing shell inside a housing bore of a connecting rod. The main investigated parameters were defined by authors experience in this field. In the first stage of research, a special test stand was designed in order to allow measuring the real values of the friction torque for different variants of bearing shell geometries and assembly conditions, additionally analysing the influence of the locking lip. Subsequently, theoretical computer-assisted FEM simulations were performed.
