System and method for the identification of a mechanical component, in particular a bearing or a hub bearing unit of a vehicle or a ring thereof, consisting of a marking applied directly onto an exposed surface of the mechanical component, performed using a photopolymerizable ceramic ink which is printed on the exposed surface by an inkjet printer having a resolution equal to, or greater than, 700 dpi and which is at least partly vitrified using a heat treatment at a temperature equal to or higher than 700° C., preferably after fixing of the ceramic ink on the exposed surface by UV irradiation.

A method for determining a load in a working machine including a linkage to be connected to an implement includes determining pressure in a first hydraulic cylinder and pressure in a second hydraulic cylinder arranged to control the linkage and determining at least one link angle between at least two links in the linkage. The method further includes, for a selected linkage bearing, determining at least two perpendicular force components acting on the selected linkage bearing, based on the determined pressure in each of the first and second cylinders and the at least one link angle; and determining a load on the selected linkage bearing as a linear combination of the at least two perpendicular force components using predetermined constants for the linear combination.

A plastic sliding component for mounting without lubricant in a sliding bearing is proposed, having a moulded part which is manufactured from plastic and has a sliding face for movably guiding two bearing parts relative to one another. An electric function circuit with a sensor function for acquiring an operating parameter is arranged on the moulded part. The invention proposes that the function circuit comprises at least one conductor track structure which is formed on the moulded part as a carrier of the conductor track structure. The function circuit can preferably be applied to the prefabricated moulded part, which is made of plastic, by means of an additive fabrication method (AM method).

A ball joint for a chassis of a vehicle. The ball joint has an inner joint portion (2) and a slide bearing (7). The inner joint portion (2) is movably fitted in the slide bearing (7). The ball joint further has a closure element (5) for closing a joint housing. The slide bearing (7) and the closure element (5) are connected to one another. To reduce the number of components and/or the number of assembly steps, the ball joint (1) is characterized in that the slide bearing (7), for the inner joint portion (2), is made as a single, one-piece plastic component (6).

A device for capturing and transmitting data of a bearing of a steel mill or rolling mill includes a sensor with a data processing unit arranged in a bearing housing capturing and storing data of a bearing. A data transmission unit in the bearing housing wirelessly transmits data of the sensor to a remote receiver. An energy receiving unit in the bearing housing receives energy wirelessly and transmits it to the data transmission unit and the data processing unit. An energy source with an energy transmitting unit arranged outside the bearing housing supply the energy unit wirelessly. The energy transmitting unit is covered by the bearing housing and is arranged on or in a structural part which adjoins the bearing housing and is part of the supporting structure of mill and remains on the supporting structure of the mill when the bearing housing is removed for maintenance purposes.

Conveyor idler monitoring apparatus, systems and methods are provided. In some embodiments, one or more sensors (e.g., temperature sensors, load sensors, etc.) are supported by the shaft of a conveyor idler. In some embodiments, one or more sensors are in data communication with a wireless transmitter. In some embodiments, a power generator driven by rotation of the idler is in electrical communication with one or more sensors and/or a wireless transmitter. In some embodiments, idler monitoring systems are in data communication with a conveyor monitoring system and/or operational monitoring system.

A sliding element for an engine may include a polymer-based overlay layer and a metallic substrate. The polymer-based overlay layer may include a polymer-based matrix, a metal particulate, and a pigment. The pigment may have a hardness of at least 4 on the Mohs hardness scale.

A linked hinge mechanism includes a first member, a second member, a hinge unit and a passive unit. The hinge unit is connected to the first member and the second member, wherein the first member is adapted to be rotated relative to the second member via the hinge unit. The passive unit is adapted to be moved by the movement of the hinge unit, wherein the passive unit is adapted to be rotated by the movement of the hinge unit in only a portion of the whole rotation range of the hinge unit.

A condition monitoring system for monitoring a rolling element bearing. The system includes a signal processing unit and a vibration energy harvester. The vibration energy harvester provides an electromagnetic transducer. When vibrated, a coil moves relative to a static electromagnetic field to create power. To create a compact and efficient condition monitoring system, it uses the electromagnetic transducer also as a vibration sensor, a velocity sensor. The signal processing unit determines if the bearing has been damaged and in some embodiments also the extent of the damage. The electromagnetic transducer is attached directly or indirectly to the rolling element bearing.

The present invention relates to a detection system for detecting wear of a ball-joint connection device of a pitch rod. The detection system includes at least one measurement assembly, said at least one measurement assembly having at least one deformation gauge for placing on said pitch rod, said detection system comprising at least one electrical conditioning circuit connected to at least one said deformation gauge and to at least one electrical energy source, said electrical conditioning circuit being configured to generate a measurement signal that varies as a function of deformation of said at least one deformation gauge and as a function of said wear.
