“…This solution has a wider installation tolerance and zero operational tolerance between the surfaces in contact. Shrink fitting as a method for joining two mechanical parts has been investigated over many years, e.g., McMillan et al [7] studied the slip between a hub and a shaft in a shrink-fit assembly subjected to axial load, and Mouaa et al [8] reported an analytical methodology to analyze the elastic-plastic stresses in a shrink fit with a solid shaft.…”

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