Title:
ROLLING BEARING DEVICE
Document Type and Number:
Japanese Patent JP2015075142
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rolling bearing device in which a creep is hardly generated even if the device becomes high in temperature.SOLUTION: A rolling bearing device comprises: an outer ring 21 having an annular groove at an external periphery, and a raceway face at an internal periphery; an inner ring 30 which is arranged at an internal peripheral side of the outer ring 21, and has a raceway face at an external periphery; a plurality of rolling bodies 40 which are arranged between both the raceway faces, and roll with respect to the faces; a fitting member 11 which has a fitting face 12 fit to the external periphery of the outer ring 21, and is constituted of a material which is larger than the outer ring 21 in a linear expansion coefficient; and a rubber-made ring-shaped O-ring 65 which is embedded into the annular groove, and contacts with the fitting face. A resin-made ring-shaped temperature sensing member 70 is fit into the annular groove, and the temperature sensing member 70 has a linear expansion coefficient larger than a liner expansion coefficient of the fitting member 11, generates a pressing force between the temperature sensing member 70 and the fitting member 11 only at a high temperature, and also generates a pressing force between the temperature sensing member 70 and the outer ring 21 at least at a high temperature.
