Provided is a rotational torque inspection method for a bearing device for vehicle wheel that enables detection of an abnormality in a component or step occurring midway in the manufacturing of the wheel bearing device. This rotational torque inspection method for a wheel bearing device 1 comprises: a press-fitting step S02; a post-press-fitting rotational torque measurement step S04 for measuring a rotational torque T1 of the wheel bearing device 1 when, after the press-fitting step S02, the hub ring 3 and the inner ring 4 that are inner members and an outer ring 2 that is an outer member are rotated in a relative manner; and a post-press-fitting rotational torque determination step S05 for determining the fitness of the rotational torque T1 by whether or not the rotational torque T1 measured in the post-press-fitting rotational torque measurement step S04 is within a range of standard values S1.

An abnormality diagnosis method of a rolling bearing used in rotating machinery includes: a time acquisition step of acquiring, from an output signal detected by a sensor during the rotation of the rolling bearing, an entry time when a rolling element enters a flaking region of a bearing ring, and an escape time when the rolling element escapes from the flaking region of the bearing ring; and an estimation step of estimating a flaking size based on a flaking passage time, which is a time difference between the entry time and the escape time. When the bearing ring receives repeated load from the rolling element, the progress of the flaking occurring in the bearing ring can be quantitatively evaluated.

A washing machine appliance includes a wash basket rotatably mounted within a wash tub and supported by a front bearing and a rear bearing. A method of operating the washing machine appliance includes rotating the wash basket within the wash tub at a basket speed and obtaining first and second displacement amplitudes of the wash tub. Bearing forces at the front and rear bearings are obtained based on the basket speed and the displacement amplitudes. The determined bearing force at the front bearing is compared to a front limit. The determined bearing force at the rear bearing is compared to a rear limit. If the determined bearing force value at either of the front bearing or the rear bearing is greater than or equal to the respective limit, an operating parameter of the washing machine appliance is adjusted to limit bearing forces resulting from out-of-balance loads.

In a vehicle suspension assembly a sensorized system applied to a wheel hub unit, in which radially outer cylindrical surface of an outer ring of the wheel hub unit configured for coupling to a suspension upright or knuckle has four circumferential flats formed to be angularly spaced from each other on the radially outer lateral cylindrical surface, each flat delimiting a plane surface which extends axially over a pair of annular tracks for rolling bodies of the outer ring; each flat carries integrally a sensor module including a pair of extensometers positioned parallel to each other and each at the position of a respective annular track, orientated in a circumferential direction so as to extend along a circumferential development of the annular track; an electrical circuit picks up a signal from each sensor module and sends it to a data socket carried by the suspension upright or knuckle.
