A piezoelectric strain sensor unit for a rolling bearing includes a piezoelectric strain sensor, and a sensor holder provided with a main body having a front face intended to be into contact with a component of the rolling bearing and a rear face, and with at least two flexible arms mounted on the main body and supporting opposite ends of the piezoelectric strain sensor, the piezoelectric strain sensor being axially located on the side of the rear face of the main body while remaining spaced apart from the rear face. The sensor holder is provided with a central pin which protrudes axially with regard to the front face of the main body and which is axially moveable with regard the main body, the central pin axially abutting onto the piezoelectric strain sensor.

Piezoelectric strain sensor unit for a rolling bearing

A rolling element bearing may potentially experience uneven loads across the length of its rolling elements due to either one or more of design errors, manufacturing errors or installation errors or any combination of these errors. The invention enables a physical measurement to be carried out on these potentially uneven loads on the rolling elements of a rolling element bearing by a technique that makes use of two or more load or strain sensors for measurement of roller load induced strain signals along a length of a rolling element in a rolling element bearing with rollers, such as cylindrical rollers for bearing arrangements.

Condition monitoring

A sensor device for monitoring a component, the sensor device providing a zinc alloy mounting element comprising a bracket and a bolt. The zinc alloy of the zinc alloy mounting element increases a rigidity of the mounting element, the zinc alloy having less than 5% aluminum by weight and less than 5% copper by weight; and at least one sensor coupled to the zinc alloy mounting element for mounting to the component of interest. The at least one sensor measures at least one condition parameter of the component.

Sensor device with mounting element

A flanged shaft having a shaft part including a bearing seat for mounting an inner ring of a bearing arrangement and a flange part at a first side of the shaft. The flange part has an axially inner surface for axially retaining the inner ring. The flanged shaft is instrumented with one or more sensor units. Each unit having a measuring surface formed by an axially inner surface of at least one contact plate on which one or more sensors are provided for monitoring one or more operating parameters of the bearing arrangement. According to the invention, each of the one or more sensor units is arranged in a corresponding recess that extends through the flange part such that the measuring surface lies flush with or protrudes somewhat beyond the axially inner surface of the flange part.

Instrumented shaft for condition monitoring

A device for monitoring a bearing, wherein the device comprises at least one sensor configured to obtain data concerning at least one of the factors that influences the residual life of the bearing. The device is a portable device and comprises a non-permanent attachment feature configured to non-permanently attach the device to a surface of the bearing so that at least a part of the at least one sensor is pressed against the surface of the bearing.

Obtaining data concerning factors influencing a residual life of a bearing

A sensor unit for a bearing includes a main body, a sensor holder and a mounting bracket. The sensor holder has a measurement surface in a first plane on which at least one sensor is provided for measuring an operating parameter of the bearing. Each mounting bracket has an attachment portion having an attachment surface. The sensor unit is configured to contact the bearing ring that forms part of an assembly in which the bearing is mounted. The sensor holder has one or more extendable legs that are extendable in a longitudinal direction perpendicular to the first plane, such that the measurement surface is adjustable in longitudinal direction relative to the main body. The mounting brackets are linearly movable and pivotable relative to the main body. The sensor unit has a first attachment position and a second attachment position.
