Abstract
A journal bearing is provided that supports a rotating shaft to be rotatable around a central axis and includes: a bearing main body that has a sliding contact surface that is in sliding contact with the rotating shaft, an outer circumferential surface that is directed outward in the radial direction to face a side opposite to the sliding contact surface, a recess that is recessed from an outer circumferential surface of the bearing main body inward in the radial direction, and a groove that continuously extends from the recess; a sensor main body that is housed in the recess; and a sensor wiring whose one end is connected to the sensor main body and in which a part thereof in a length direction is housed in the groove.
Claims18
A journal bearing that supports a rotating shaft to be rotatable around a central axis, comprising:
- a bearing main body configured to have a sliding contact surface which is configured to be brought into slidable contact with the rotating shaft and is directed inward in a radial direction, an outer circumferential surface that is directed outward in the radial direction to face a side opposite to the sliding contact surface, a recess that is recessed from the outer circumferential surface inward in the radial direction, and a groove that is recessed from the outer circumferential surface to be continuous with the recess and extends along the outer circumferential surface;
- a sensor main body housed in the recess;
- and
- a sensor wiring whose one end is connected to the sensor main body and in which a part thereof in a length direction is housed in the groove.
A journal bearing-manufacturing method, comprising:
- a process of preparing:
- a bearing main body that has a sliding contact surface that is brought into slidable contact with the rotating shaft and is directed inward in a radial direction, an outer circumferential surface that is directed outward in the radial direction to face a side opposite to the sliding contact surface, a recess that is recessed from the outer circumferential surface inward in the radial direction, and a groove that is recessed from the outer circumferential surface to be continuous with the recess and extends along the outer circumferential surface;
- a sensor main body that is able to be housed in the recess;
- and a sensor wiring whose one end is connected to the sensor main body and in which a part thereof in a length direction is able to be housed in the groove;
- and
- a process of housing the sensor main body in the recess of the bearing main body, housing the part of the sensor wiring whose one end is connected to the sensor main body in the groove, and fixing the sensor main body in the recess using an adhesive.
