Abstract
The present invention relates to a shaft ground ring for preventing bearing electrical erosion caused by leakage current, and more specifically, the shaft ground ring of the present invention includes a brush that contacts the outer circumferential surface of the shaft to discharge leakage current flowing through the shaft to the outside, and a pair of cases disposed opposite each other relative to the brush so as to enclose the brush, wherein the shaft ground ring, by reducing the number of components, facilitates the manufacture and assembly of the components, and further includes a flow path through which cooling fluid can pass.
