In a spindle gear mechanism () having a spindle component () with a spindle thread () which has a pitch which alters over a longitudinal axis of the spindle component (), and having a threaded component () which engages in the spindle thread (), wherein the two components () can be displaced relative to one another in relation to the longitudinal axis () of the spindle component (), provision is made, for the purpose of straightforward production capability and suitability for a large number of applications, for the threaded component () to have at least one freely movable threaded element () which engages in the spindle thread () and, during operation, adapts automatically to the pitch of the spindle thread ().

Wear detection in a plain bearing is proposed, with a first component comprising at least one sliding element of plastics material, which has a sliding surface for mobile guidance of a second component relative to the first component. The first component, in particular the sliding element, has a device for detecting wear in a critical region of the sliding element, in particular at the sliding surface thereof, with a transponder and with a detector element which cooperates with the transponder and is arranged on the sliding element. The detector element changes the behavior of the transponder when a predetermined degree of wear is reached in the critical region of the plastics sliding element, such that the wear-induced change is wirelessly detectable. The system and detection method are particularly advantageous for plain bearings for a lubricant-free bearing arrangement.

Plain bearing, plastics sliding element, system and method for wear detection

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).
