<p><P>PROBLEM TO BE SOLVED: To provide an insulated rolling bearing with excellent insulation properties capable of being manufactured at a low cost, capable of arranging an insulation layer with reduced processing man-hours, free from defect of a chamfer part and capable of being assembled in a housing and the like easily. <P>SOLUTION: This insulated rolling bearing comprises an inner ring 2, an outer ring 3, a plurality of rolling elements 4 interposed between rolling surfaces of these inner and outer rings and an insulation sleeve 8 fit to an outer peripheral part of the outer ring 3. The insulation sleeve 8 is a multilayered structure with an insulation layer 8b consisting of a ceramics coating formed by an AD (aerosol deposition) method as a middle layer. The multilayered structure consists of an inner annular sleeve 8a fit to the outer peripheral part of the outer ring, an outer annular sleeve 8c fit to the housing and an insulation layer 8b interposed between the inner and outer annular sleeves as a middle layer. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
