Abstract
A wave generator with a sealing plate includes an elliptical hub having a rotating axis. An inner ring of a bearing fits around a peripheral surface of the elliptical hub. The inner ring and an outer ring of the bearing change from a circular shape to an elliptical shape along with the peripheral surface. The inner ring and the elliptical hub are rotatable around the rotating axis. A sealing plate which is elliptical fits around the inner ring. An outer edge of the sealing plate abuts against the outer ring. The sealing plate is driven by the elliptical hub and the inner ring to rotate around the rotating axis and shelters a side of the rolling bodies. In the present invention, the sealing plate is installed in the bearing to shelter the rolling bodies after the bearing deforms.
