摘要： The object is to stably support pillars forming a retainer of the roller type one-way clutch. An outer race (11) has one end thereof closed by a flange (16) and the other end closed by a lid (22). A predetermined number of pocket bottom surfaces (17) are continuously formed on the radially inner surface of the outer race (11). A pocket (24) is defined by pillars (23) inserted on both circumferential sides of each pocket bottom surface (17). The pillars (23) have their base portions integrally joined to the lid (22), thereby forming a retainer (12). The pillars (23) have protrusions (32) at their distal ends which are fixed to holes (19) formed in the flange (16) by e.g. fusing, thereby fixing the retainer (12) to the outer race (11).

摘要： An annular sensor holder (5) has an axial end (15) including a protrusion (18). The axial end (15) is fitted in a circumferential groove (7), such as a seal groove, of a bearing race (2) fitted to a stationary member (9) so that the sensor holder (5) can slide in the circumferential direction relative to the bearing race (2). In this state, the sensor holder (5) is coupled to the stationary member (9) by a fixing arrangement (19). Thus, when the bearing race (2) creeps, the sensor holder (5) slides relative to the bearing race (2) and does not rotate relative to the stationary member (9). This prevents breakage of connecting wires.

摘要： Disclosed is a bearing assembly with a sensor, in which a sensor holder that is formed of a synthetic resin and is the annular member having ends is supported on an outer race using a circumferential groove of the outer race of a rolling bearing, and the sensor holder is adapted to be strongly fixed in position by a spring member having circumferential half-split elastic recovery portions. Because spring forces by which the sensor holder is strongly fixed in position as described above can be increased, the sensor holder can be more strongly fixed in position. A spring member (15) is a formed-wire spring formed of a square sectional wire, which includes a main portion (16) fitted in an annular groove (14) of a sensor holder (7), and opposite end portions (17) that circumferentially protrude from the annular groove (14) and are located inside an open recess (18) of the sensor holder (7). The opposite end portions (17) of the spring member (15) overlap in an axial direction when the main portion (16) is fitted in the annular groove (14), and are portions that abut and are deflected when one of the end portions (17) is shifted to remove the overlapping. The forces (F) caused by elastic recovery of the deflected end portions (17) increase the force of the main portion (16) pushing the sensor holder (7) in a radially outward direction. As a result, the spring forces by which the sensor holder (7) is strongly fixed in position are increased.

The magnetic encoder 7 includes a ring shaped rotational speed to-be-detected member 7A having a plurality of magnetic poles alternating with each other, and a origin position to-be-detected element 7Ba arranged axially in a portion of the circumferential direction of the to-be-detected member 7A. Rotational speed and origin position magnetic sensors are mounted on the stationary ring so as to respectively confront the rotational speed and origin position to-be-detected elements. A magnetized restoration element 7Bb is disposed in a circumferential portion of the magnetic encoder 7, where it confronts the origin position magnetic sensor, and except the second to-be-detected member 7Ba.

摘要： A compact rolling bearing with a rotation sensor is proposed which has a shortened axial length of a housing for mounting the rotation sensor. The rolling bearing comprises a rotating bearing ring and a fixed bearing ring, and the rotation sensor comprises a rotating element mounted to the rotating bearing ring and a detecting element mounted on the fixed bearing ring so as to oppose the rotating element, and an electric circuit board. The electric circuit board has a flexibility. With this arrangement, it is possible to mount the electric circuit board in a curved state in a limited space on a peripheral wall of the sensor housing, and thus to shorten the axial length of the sensor housing. This provides a compact rolling bearing with the rotation sensor. Another embodiment has a magnetic encoder, the binder for which is heat-resistant nitrile rubber, fluorine rubber or silicone rubber.

摘要： In a magnetically suspended type pump, an operating state of the pump can be obtained without using a pressure gauge and a flowmeter. In addition, in the case where the magnetically suspended type pump is applied to a blood pump, in order to reduce the number of connections in a flow path and to avoid thrombus formation, a correlation between current flowing in a motor and flow or a correlation between current flowing in the motor and pressure is obtained in advance, and the speed of rotation of motor is varied by a speed of rotation control circuit in response to an instruction from a CPU circuit, based on the obtained correlation between current and flow or between current and pressure, whereby flow or pressure is controlled.
