ANTENNA-EQUIPPED ROLLING BEARING

摘要

PROBLEM TO BE SOLVED: To provide an antenna-equipped rolling bearing wherein a seal and an antenna is easily incorporated therein at reduced cost using the small number of part items.

SOLUTION: The rolling bearing has an inner member 3 and an outer member 2 which are rotatable relative to each other via rolling elements 4. The rolling bearing has the seal 18 for sealing an end of an annular space between the inner member 3 and the outer member 2. The antenna 43 for transmitting signals is embedded in the seal 18. A generator 11 which generates electric power using the relative rotation between the outer and inner members is provided between the outer and inner members 2 and 3. The antenna 43 serves as a means for transmitting rotation signals detected at the generator 11 or signals of a sensor which operates using the generator 11 as a power supply.
