TENSIONING SYSTEM FOR A TRACTION MECHANISM DRIVE

摘要

The invention relates to a tensioning system (1) of a traction mechanism drive, comprising a base part (2) connected in one piece to a pivot arm (5), on the end of which a tensioning roller connected to a traction drive is disposed. The base part (2) is pivotable via a rotary bearing (7). The construction of the rotary bearing comprises a bushing (11) fixed by means of a holder (13), said bushing being fixed in place relative to a machine part (15) by means of a joint bond (30). The joint bond (30) is formed by a centering sleeve (31) inserted into a bore (32) of the bushing (11) and in a bore (33) of the machine part (15).
