AI Technical Summary
Traditional spherical plain bearing testing equipment cannot accurately simulate the interaction between loads in the X, Y, and Z directions and the over-constraint problem. It also cannot simulate the axial rotation, tilting oscillation, and combined motion of the inner ring, resulting in inaccurate test results.
Design a three-axis loading device that uses a spherical bottom, a cover plate with a spherical groove, and a loading disk. Through spherical clearance fit, loads in the Z, X, and Y directions can be applied independently. The inner ring can rotate around the X-axis and swing around the Y-axis by using a rod end spherical bearing, thus avoiding mutual interference between loads.
It achieves a more accurate simulation of the force and motion of spherical plain bearings in actual operation, and can independently apply loads in the X, Y, and Z directions to meet static and fatigue loading requirements. The structure is simple, flexible and versatile.
