Abstract: A bushing assembly (50) for an eccentric machine such as a gyratory crusher (1). The bushing assembly (50) comprising a first bushing (51) having a center axis (105) and a first cavity (53) being coaxial with a first eccentric axis (106). A second bushing (61) having a second center axis (205) is accommodated in the first cavity (53). The second bushing (61) having a second cavity (65) being coaxial with a second eccentric axis (206). The first bushing (51) and second bushing (61) are configured to rotate individually with different relative velocities whereby the distance between the second center axis and the first eccentric axis varies.
A drive mechanism is configured for rotating the second bushing (61). The drive mechanism comprising a first gear ring (63) configured for engaging with a driving means. The first gear ring (63) and the second bushing (61) are rotationally coupled by a flexible coupling (64), said flexible coupling configured to accommodate for an angular and/or axial misalignment of the first rotational axis and second rotational axis.
