A rolling bearing device equipped with IC tags is proposed which includes a tapered roller bearing. In the tapered roller bearing, tapered rollers are rotatably retained by a retainer between an outer race and an inner race. The outer end metal surface portions of the inner race and the outer race have holes, in which IC tags capable of non-contact communication are attached through shock-absorbing bodies made of an elastic rubber material. Even when the surface of the outer race or inner race is a surface for receiving a preload, the strain, vibration or impact caused by external force and exerted on the surface is absorbed in the shock-absorbing body made of an elastic rubber material.

To provide a wireless sensor system, in which an abnormal power supply in the power supply section can be ascertained, for avoiding a malfunction of the system and accomplishing a stable power supply with reduction of the consumption of a power being transmitted, the wireless sensor system includes wireless sensor units and a sensor signal receiving unit. The wireless sensor units include a sensor section for detecting a detection object, a sensor signal transmitting section for transmitting by wireless a sensor signal from the sensor section, and a power supply section having a power receiving section for receiving a driving power transmitted by wireless. In this system, a power supply monitoring section is provided for monitoring the voltage of the power supply section. The sensor signal receiving unit includes a monitor dependent power control section for regulating the power to be transmitted, depending on a monitored result of the power monitoring section.

An object of the present invention is to provide a bearing device which includes a lubricant supply device that is capable of supplying lubrication oil from a lubrication oil tank to a rolling bearing without time lag and without using a pump, and at a high level of energy efficiency. A bearing device is constituted by a rolling bearing and a lubricant supply device combined with each other. The lubricant supply device includes a lubrication oil tank which stores pressurized lubrication oil and has a lubrication oil discharge spout; an open/close valve which opens/closes the discharge spout of the lubrication oil tank; a driving section which operates the open/close valve; and an electric power source section which generates electric energy for operation of the driving section. The lubricant supply device is attached to the rolling bearing or to a spacer adjacent thereto.

In a magnetic sensor 7, a tubular duct 9a for output cables 12 is formed integrally with a sensor housing 9, provided with an opening 14 having a uniform width from a proximal end to a distal end of the duct 9a on a side face thereof. The output cables 12 are mounted through the duct 9a from this opening 14, and then a slidable lid 15 is mounted to close the opening 14. Thus damage to the output cables 12 connected to the magnetic sensor 7 is prevented and, at the same time, drawing the output cables 12 outside the sensor housing 9 is made easier.

A bearing assembly with a rotation sensor is proposed which can be fixed to a stationary member in the form of a thin plate formed with a through hole for positioning the bearing assembly so that its outer race can be easily rotationally fixed to the stationary member. The bearing assembly includes a stationary member (7) in the form of a thin plate member formed with a through hole (7a) extending in the thickness direction of the thin plate member and defining a radially inner portion (7b) capable of radially positioning a radially outer portion (4d) of the outer race (4) of the rolling bearing (1), and a snap ring (8) fitted in a ring groove (4a) formed in the outer race (4). The stationary member (7) has an anti-rotation portion (7c, 22) which is configured to be inserted between circumferentially spaced apart ends (8a, 15d) of the snap ring (8) or the sensor case (5) with the rolling bearing (1) mounted between the radially inner portion (7b) and a rotary shaft (9). The anti-rotation portion (7c, 22) thus prevents rotation of the outer race (4) by circumferentially engaging either of the circumferentially spaced apart ends (8a, 15d).

Provided is an in-vehicle power supply apparatus which supplies power to both a high-power load such as an actuator, and the CPU for controlling the high-lower load, and which is capable of preventing reduction in voltage of the CPU even when voltage of the in-vehicle power supply is momentarily reduced due to power consumption of the high-power load, and which include an auxiliary power supply having its capacity reduced so as to enable reduction of the size of the power supply apparatus. The in-vehicle power supply apparatus for supplying a power to both a power load, and a CPU for controlling the power load comprises: a first distribution line for distributing, to the power load, the power supplied from an in-vehicle power supply through a bus; a second distribution line for distributing, to the CPU, the power supplied from the in-vehicle power supply through the bus; an auxiliary power supply, connected to the second distribution line, for supplying the power to the CPU when a voltage is reduced in the bus; and a backward flow prevention section for preventing a charge stored in the auxiliary power supply from flowing into the bus.

摘要:
To provide a bearing with integrated rotation sensor capable of detecting the rotational speed and the origin position without being affected by an external magnetic field, the bearing includes a rotating ring, a magnetic encoder 7 mounted on the rotating ring, and a stationary ring. 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.
