Abstract (en)

[origin: EP2772431A2] A shear bearing (120) for a rotor system (100) has a four bar linkage and a grip configured to retain a flexural yoke (106) and the grip is connected between a first set of opposing links of the four bar linkage. A rotor system (100) has a flexural yoke (106) and a shear bearing (120) configured to perform at least one of transmitting forces to the yoke (106) and receiving forces from the yoke (106), wherein the yoke (106) is free of cavities for receiving the shear bearing (120). A rotational system (100) has a flexural yoke (106) and a damper (136) disposed on a surface of the yoke (106).
