The architecture of the mounting of a power transmission of a rotorcraft, comprising a vibration damper device implementing the shock absorbers laminates

摘要

The present invention relates to an architecture of the assembly to the edge of a rotorcraft of a main power transmission is carried by the suspension mast of a main rotor and supported by a chassis by means of a vibration damper device implementing the laminated dampers (12). The laminated dampers (12) comprise a body (16) with laminated armatures (17,18) at its axial end faces. At least one of the reinforcements (17,18) comprises a stop (19) of axial bearing radially sliding of the reinforcements (17,18) against one another in the case of excessive wear of the laminated body (16), said bearing limiting the travel of the pivoting of the main gearbox to a predetermined wear threshold of the body (16 laminated).
