| 摘要 |
The present invention relates to a drive chain (1) comprising a plurality of chain links (2, 3) interconnected by pivot pins (4). The links (2) have bushes (6) through which the pivot pins (4) extend, and which are of a resiliently torsionally deformable material. The pivot pins (4) are non-rotatably secured in the bushes (6) so that flexing of the chain (1) may occur without relative rotation at the interface between the bushes (6) and the pins (4) by means of rotational deformation of the bushes (6). |
