Abstract: A system monitoring statuses such as presence and absence of abnormality and lifetime of a machine component such as, for example, a bearing having rolling elements, includes: a plurality of determining units respectively connected with a plurality of sensors, and a control unit connected with the determining units. Each sensor is disposed on the machine component of the associated rolling bearing to detect an influence signal resulting from passage of the rolling element induced in the machine component. Each determining unit determines, according a process set-up condition, the presence and absence of an abnormality and lifetime of the machine component associated with the sensor in reference to an output signal from the sensors. The control unit collects a result of determination performed by each determining unit. In this way, with a simplified structure, monitoring can be achieved at a low cost, precisely and efficiently.

Abstract: A shaft coupling includes plates fitted on ends of input and output shafts, respectively. A plurality of guide grooves are formed in the opposed surfaces of the plates, respectively, so that each of the grooves extends perpendicular to the corresponding groove formed in the other plate. A steel ball is disposed between each pair of guide grooves of the plates at a portion where the pair of grooves cross each other. When the steel balls are pushed by the driving plate, they push the driven plate while rolling in the guide grooves, with their movements restricted by a retainer in the radial direction of the plates. Thus, large power can be smoothly transmitted between the rotary members with less frictional resistance. The offset amount can be changed easily. Between the plates, there are only the steel balls and the retainer.

Abstract: An object is to provide a shaft coupling which is short in axial dimension, which can transmit large power between shafts even if the offset amount of the shafts is large, and which is less expensive and can be assembled easily. The shaft coupling includes plates 1 and 2 fitted on ends of input and output shafts A and B, respectively. A plurality of guide grooves 5 and 6 are formed in the opposed surfaces of the plates 1 and 2, respectively, so that each of the grooves 5 and 6 extend perpendicular to the corresponding groove formed in the other plate. A steel ball is disposed between each pair of guide grooves 5 and 6 of the plates 1 and 2 at a portion where the pair of grooves 5 and 6 cross each other. When the steel balls are pushed by the driving plate 1, they push the driven plate 2 while rolling in the guide grooves 5 and 6, with their movements restricted by a retainer 4 in the radial direction of the plates. Thus, large power can be smoothly transmitted between the rotary members with less frictional resistance. The offset amount can be changed easily. Between the plates 1 and 2, there are only the steel balls 3 and the retainer 4. Thus, the shaft coupling is sufficiently short in axial length, can be manufactured at a low cost, and can be assembled easily.

Abstract: A power transmission mechanism for a vehicle includes a clutch assembly which includes a two-way clutch and an electromagnetic clutch. The two-way clutch includes three rows of rollers retained by a retainer and disposed between a clutch inner member, which is actually a stem of a constant-velocity joint mounted on the outboard end of a drive axle, and a clutch outer member, which is actually a hub ring of a hub bearing supporting a vehicle wheel. Simply by energizing and deenergizing the electromagnet of the electromagnetic clutch, the two-way clutch can be engaged and disengaged. Since the rollers are arranged in three rows, it is possible to increase the contact area between the rollers and the clutch inner and outer members and thus the maximum torque that can be transmitted through the rollers without the need to increase the number of rollers in each row or their length or diameter.

Abstract: A ring magnet is attached to an outer ring by a magnet holding unit. A coil hold unit attached with a generator coil is provided at an inner ring to face the ring magnet. A substrate with a transmission circuit and a loop antenna is attached to the coil hold unit. Rotation of the inner ring causes the generator coil to generate power. The generated power is applied to the transmission circuit. A sensor output or the like is transmitted by the transmission circuit as a weak wave via the loop antenna to be received at the stationary side.

Abstract: A rotating side case 3b supporting the rotor 3R of an in-wheel motor 3 and a wheel 2 or a hub 4 are interconnected by a flexible coupling 10 which comprises a motor-side plate 11A and a wheel-side plate 11C having a plurality of grooves 11a and a plurality of grooves 11b formed on their opposed surfaces in the circumferential direction at an angle of 45° from the radial direction of the plates and extending in directions orthogonal to each other, respectively, small balls 11m sandwiched between the grooves 11a and 11b in such a manner that they can slide, and an intermediate plate 11B interposed between the above plates 11A and 11C and having guide holes 11s for guiding the small balls in a direction orthogonal to the radial direction of the plates and which has a small number of parts and is easily assembled. Therefore, even when the motor shaft and the wheel shaft become eccentric with each other, the drive torque of the motor 3 can be transmitted to the wheel 2 without fail, thereby making it possible to improve the assembly work efficiency of the in-wheel motor.
