TENSIONING DEVICE FOR A TRACTION MEMBER, ENGINE EQUIPPED WITH SUCH A TENSIONING DEVICE AND METHOD FOR IMPLEMENTING SAME

摘要

The present invention relates to a tensioning device having a mounting plate; a tensioning roller centered on a roller axis and mounted movably on the plate, with at least one degree of rotational freedom around a pivot axis that is off-centered relative to the roller axis between at least one initial configuration, a mounting configuration and a final configuration for tensioning the traction member positioned on the tensioning roller. The device includes means for locking the tensioning roller relative to the mounting plate in the different configurations of the tensioning device. The tensioning device has at least partially removable means for indexing the position of the tensioning roller relative to the mounting plate in the final configuration. The invention also relates to an engine equipped with at least one traction member and at least one tensioning device. The invention also relates to a method for implementing such a tensioning device.

主权项

1. A tensioning device, comprising:
a mounting plate; a tensioning roller centered on a roller axis (X4) and movably mounted on the mounting plate with at least one degree of rotational freedom around a pivot axis (X6) that is off-centered relative to the roller axis (X4) between at least one initial configuration (C0), a mounting configuration (C1) and a final configuration (C2) for tensioning (F) a traction member positioned on the tensioning roller; and locking means for locking the tensioning roller relative to the mounting plate in the different configurations of the tensioning device; wherein the tensioning device provides at least partially removable indexing means for indexing the position of the tensioning roller relative to the mounting plate in the final configuration (C2).
