Abstract
The utility model provides an elastic ring support stiffness measuring device. The measuring device comprises a fixed core rod, an elastic ring to be measured and a loading ring arranged on the outer surface of the elastic ring to be measured. The elastic ring to be measured is sleeved on the periphery of the core rod. The central axes of the core rod, the elastic ring to be measured and the loading ring coincide. The upper surface of the loading ring is a plane parallel to the central axis and waiting to be measured. By using the cooperative relation of the core rod and the loading ring to simulate the cooperative relation of an inner ring and an outer ring when the elastic ring to be measured is in an installed state, the elastic ring support stiffness measuring device tests the stiffness of the elastic ring to be measured. The elastic ring support stiffness measuring device is convenient to install. Meanwhile, a displacement sensor arranged above the plane to be measured converts the deformed linear displacement of the elastic ring to be measured into electric signals and then outputs the electric signals. The stiffness measuring precision is thus enhanced.
