Title:
INSULATED ROLLING BEARING FOR ELECTRIC-EROSION PREVENTION
Document Type and Number:
Japanese Patent JP2008039032
Kind Code:
A
Abstract:
To provide a structure capable of preventing electrical discharge phenomenon from occurring between securing grooves 11, 11 and housing 12 when a rolling bearing is incorporated in a rotation support portion.
In addition to the outer periphery face 13 and both ends faces 14, 14 in the axial direction of an outer-ring 3b, an insulating layer 6a is formed in the securing grooves 11, 11. This can prevent the electrical discharge phenomenon from occurring between a partial surface of the housing 12 and both securing grooves 11, 11 when a part of the housing 12 and these both securing grooves 11, 11 are adjacently located.
