Abstract: A method of determining the center of loading of a rolling element includes providing a rolling element body and at least three load sensors. The sensors are each positioned within a bore of the rolling element body at a separate distance from a reference position. Load measurements are taken with each one of the sensors at various positions about the circumference of the bearing and the center of loading is calculated at each one of the positions to determine the variation in axial loading about the bearing circumference.

Abstract: A monitoring device (1) for monitoring a rolling bearing (2) being mounted into an application system (4), for example a motor or generator system. The monitoring device (1) includes a sensor unit (12) for monitoring the rolling bearing (2), and a processing unit (14). The sensor unit (12) monitors the rolling bearing (2) for obtaining an actual value of at least one parameter of the rolling bearing (2). The processing unit (14) compares the actual value of the at least one parameter and a desired value of the at least one parameter. The processing unit (14) controls the application system (4) to reduce a deviation between the actual value and the desired value of the at least one parameter.

Abstract: A detection device for vehicles includes a base section fixed to a body of a vehicle, and a bearing having an outer ring member, an inner ring member, and rolling elements, which rotatably supports a wheel of the vehicle against the base section. A first bearing member of the outer ring member and the inner ring member is fixed to the wheel, and a second bearing member of the outer ring member and the inner ring member is fixed to the base section. The detection device includes a disk-shaped rotating section for detection that extends radially outward of the bearing with respect to the first bearing member, and a displacement detection section that outputs a signal in response to an axial displacement of the rotating section for detection.

The impulse ring includes a target holder, a target mounted on the target holder, and a sleeve secured to the first ring of the bearing. The sleeve is provided with an axial portion having at least one radial protrusion and a collar extending at least partially radially. The target holder is mounted radially around the axial portion of the sleeve and axially between the first ring of the bearing and the collar of the sleeve. The at least one radial protrusion of the sleeve axial portion extends into a complementary recess provided on the target holder.

Abstract: The present application provides a brushless motor and an electrical equipment. The brushless motor includes: a casing, a stator, and a rotor. The stator includes a stator core and a winding. The rotor includes a rotor core and a shaft. Two bearings are sleeved on the shaft at positions corresponding to two ends of the rotor core, respectively. The two bearing brackets are installed at two ends of the casing. The brushless motor further includes a conductive sheet, configured for adjusting a capacitive reactance between the stator core and each of the two bearing brackets. The conductive sheet is attached to an outer circumferential surface of the casing. The conductive sheet and the stator core each at least partially has an area aligned to each other in a radial direction of the casing.

Abstract: The invention is a bearing, with an inner member having an inner ring with a raceway and an inner wall assembled around an outer bearing surface of a hub. The outer bearing surface has a groove in which an annular member is arranged having an inner segment axially immobilised in the groove and an outer segment that projects to form an axial stop for the assembly of the inner ring on the hub. The inner member has an encoder. The encoder also has a frame securing it to the inner member. The frame has a stop section between the inner ring and the outer segment.

Abstract: In a bearing cap in which a sensor support part is formed on a bottom surface section of a cap body and in which an insertion hole for a rotational speed sensor is formed in the sensor support part, a recess that accommodates a tip portion of the rotational speed sensor is formed in the portion of the bottom surface section where the sensor support part is formed. The sensor support part includes a first wall section and a second wall section that are disposed, facing each other across a virtual line L passing through a center axis G1 of the bottom surface section and a center axis G2 of the insertion hole, and that are formed along the circumferential edge of the recess. Protrusions protruding from the bottom surface section are continuously provided on the outer circumferential surfaces of the first wall section and the second wall section.
