Bearing device with sensor and rolling bearing with sensor

A bearing apparatus with a sensor, furnished with a rolling bearing including in that a plurality of rolling elements are incorporated between a rotary-side bearing ring and a stationary-side bearing ring,

• a sensor enabling to detect conditions of the rolling bearing,
• a ring shaped sensor cover housing the sensor inward and secured to the stationary-side bearing ring, and
• a ring shaped presser member secured to a bearing housing or a shaft provided outside in a radius direction of the sensor cover,
• wherein an opening is defined in a determined position of the sensor cover, and is provided at its peripheral part with projections standing toward the side of the presser member,
• the presser member is formed with a cutout into which the projections are inserted for restraining rotation of the sensor cover.

In a rolling bearing structured in that a plurality of rolling elements held in a holder are rotatably incorporated between a pair of bearing rings,

• a bearing apparatus with a sensor, comprising
• a sensor for detecting conditions of a supported rotating shaft or of the rolling bearing,
• a ring shaped sensor cover secured to one end face in an axial direction of a stationary-side bearing ring, and
• a ring shaped sensor holding member secured to the sensor cover,
• wherein the sensor is fitted in a sensor holding groove provided in a determined position along a circumferential direction in the sensor holding member with a determined tightening margin owing to elastic deformation of the sensor holding member.

• a bearing apparatus with a sensor, comprising
• a sensor for detecting conditions of a supported rotating shaft or of a bearing,
• a ring shaped sensor cover of a magnetic material secured to one end face in an axial direction of a stationary-side bearing ring,
• a ring shaped sensor holding member of a non-magnetic material holding the sensor inward under a condition of being secured inward of the sensor cover, and
• a conductive member installed as covering at least one part of the sensor holding member and has an electromagnetic shield effect.
