Variable contact rolling-sliding composite bearing and design method

PendingCN122328449ACritical loadRolling sliding
This invention discloses a variable contact rolling-sliding composite bearing and its design method, relating to the field of bearing technology. The bearing includes an outer ring, an inner ring, bearing rollers, and a cage. The diameter of the bearing rollers is larger than the axial height of the cage to form an initial clearance. When the external load is small, the bearing rollers bear the load alone, and the bearing is in a pure rolling contact state. When the external load increases to the point that the bearing rollers undergo elastic deformation and the initial clearance closes, the end face of the cage contacts the raceway surface of the outer ring, sharing the load with the bearing rollers, and the bearing switches to a rolling-sliding composite contact state. The design method involves: calculating the roller deformation to determine the critical load; establishing a spring stiffness model for the rollers and cage to solve for the load distribution; checking whether the cage contact stress is lower than the yield limit; if it exceeds the limit, increasing the initial clearance and iteratively optimizing. This invention achieves adaptive switching of the bearing's operating mode, enabling low friction under light loads and high load capacity under heavy loads, and the design method is universal and reliable.
