摘要： A bearing assembly may include an integral sensor module retained within a bore in the bearing housing. The sensor module includes at least one strain gauge oriented to sense a compressive load acting on the bearing housing. The sensor module may be retained within the bore under an axial compressive load. The sensor module may include a power source and a wired or wireless communications module for transmitting information indicative of the compressive load to an external instrument or other system.

摘要： A bearing equipped with a sensor and incorporating a power generation function in a simple configuration is provided. A bearing includes an outer ring, a plurality of rolling elements, an inner ring, a cage, a seal member, a sensor, a transmission unit, and a power generation unit. The sensor is disposed in the seal member, and detects state information of the bearing. The transmission unit transmits the state information detected by the sensor to outside. The power generation unit is disposed so as to face a bearing space sandwiched between the outer ring and the inner ring, and generates electric power that is to be supplied to the sensor and the transmission unit. The power generation unit includes an element that converts stress into electromotive force.

摘要： A sensor bearing unit includes a bearing having a first ring and a second ring, and an impulse ring provided with a target holder, with a target mounted on the target holder, and with a sleeve secured to the first ring. The target holder having a mounting portion secured to the first ring of the bearing. The target holder has at least anti-rotation feature axially spaced apart from a free end of the mounting portion and cooperating with a complementary anti-rotation feature of the first ring so as to prevent angular movement of the impulse ring relative to the first ring. The anti-rotation feature of the target holder extends into the complementary anti-rotation feature of the first ring.

摘要： This application relates to an absolute position detection device and detection method of a rotating body using a magnetic material. The device may include magnets coupled to a rotating body and configured to rotate together and having n pole pairs, wherein n is a natural number and (n+1) magnetic materials arranged adjacent to the magnets, spaced apart from each other by a predetermined interval, and configured to rotate together with the rotating body. The device may also include a first Hall sensor spaced apart from the magnets, installed to allow the magnetic materials to rotate in a space between the first Hall sensor and the magnets and configured to output a first signal based on the magnets when the magnetic materials approach the first Hall sensor. The device may further include a controller configured to measure an absolute position of the rotating body using the first signal.

摘要： A bearing arrangement includes two bearing rings which can be rotated with respect to one another about a common axis, an annular module carrier, an encoder, and at least one sensor module. The module carrier is arranged axially on one of the two bearing rings. The encoder is arranged on the other one of the two bearing rings. The at least one sensor module is arranged in the module carrier. In some embodiments, the module carrier has a cut-out on at least one of its axial side surfaces. through which a lubricant can be introduced into the bearing. The cut-out is arranged circumferentially in the region away from the sensor modules. In other embodiments, the module carrier has at least one predetermined break point for configuring a cut-out.

摘要： A combined insulator and conductor assembly is for a bearing disposable between a shaft and a housing and includes an annular insulator disposeable about the bearing outer ring. The insulator is configured to prevent electric current flow between the outer ring and the housing and includes one or more axial mounting tabs. An electrical conductor has an outer radial end, an inner radial end and at least one retainer, the at least one retainer being engageable with the at least one mounting tab to releasably couple the conductor with the insulator. Each retainer includes a radially-extending prong engageable with a separate tab. The conductor outer radial end or/and a portion of the conductor between the outer and inner ends is conductively engageable with the housing and the conductor inner radial end being conductively engageable with the shaft so as to provide a conductive path between the shaft and the housing.
