| 摘要 |
This invention relates to a device for correcting the alignment of the machining of a chainset housing (1b), the housing comprising a pair of half-casings (2a, 2b) inserted in one of the openings of the housing (1b) to position the parts (3a, 3b) of a pedalling effort or chain tension sensor which pivots inside the casing (2) and positions the shaft of the chainset (4) so as to rotate eccentrically compared to the pivot axis (Y-Y′) of the sensor (3) inside the casing (2), said device being characterized in that the sensor enables pivoting of the half-casings via a rolling-contact bearing (5) which, in a cross section passing through the axes of the half-casings, allows a ball-joint-like turning of the pivot axis of the effort sensor (3) with respect to the axes of the half-casings in order to allow the pivot axis of the sensor to be positioned independently of the axes of the two half-casings so that errors of alignment between the axes of the two half-casings can be eliminated.
