Assignee: IGUS GMBH
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  F | IPC F  H

Claim 0:
1. An energy guide chain (1) with wear detection, comprising a number of chain links, which are configured for protected guidance of lines between a first connection end (F) and a second connection end (M) movable relative thereto, wherein each chain link has at least one link plate (5) and link plates (5) of adjacent chain links are each connected together in the longitudinal direction (L) by an articulated joint with a nominal swivel axis (A), wherein each articulated joint comprises
a pin (6A),
a corresponding receptacle (6B), and
at least one detection unit (10, 20, 30, 40, 50, 120) for detecting wear on at least one chain link, the at least one detection unit (10, 20, 30, 40, 50, 120) comprises
a first electrical component (11, 41, 51, 121), which is attached with a predetermined orientation to a first chain link, and
a second electrical component (12, 42, 52, 122), which is attached with a predetermined orientation to an adjacent second chain link that is articulatedly connected to the first chain link,
wherein the electrical components interact in contactlessly coupled manner to sense a change in the coupling in the event of wear-related occurrence of radial and/or axial play in the articulated joint between two chain links.
