An Investigation of the Effects and Consequences of Combining Expanding Dual Pin with Radial Spherical Plain Bearings

An expanding pin locks the assembly to its supports and bearings prevents any relative movements between surfaces in contact. In this study, diameter changes of bearing inner ring as a function pin’s tightening torque were studied. addition, required rotational moment set complete locked an solution was studied by exposing combination increasing radially outwards directed load from bolt torquing external inwards hydraulic jack. The type Radial Spherical Plain Bearings (RSPBs), GE 80 ES, steel/steel, loaded externally up their maximum dynamic limit 400 kN. results indicate major reduction rotation when is expanded use pin. indicates reduced contact pressure friction force two rings, which ultimately can have effect on surface wear positive operational lifetime.
