Abstract (en)
[origin: CN113529539A] An unbalance arrangement for a compactor roller of a soil compacter includes a first unbalance mass unit (34) rotatable around an unbalance axis (U) of rotation having a first center (M1) of mass eccentric with respect to the unbalance axis (U) of rotation, a second unbalance mass unit (36) rotatable around the unbalance axis (U) of rotation having a second center (M2) of mass eccentric with respect to the unbalance axis of rotation, an unbalance drive (42) for jointly driving the first unbalance mass unit (34) and the second unbalance mass unit (36) to rotate around the unbalance axis (U) of rotation, and a phase position adjustment unit (46) for adjusting a phase position of the first center (M1) of mass with respect to the second center (M2) of mass around the unbalance axis (U) of rotation. The phase position adjustment unit (46) includes a spur gear arrangement (68) in the torque transmission path between the unbalance drive (42) and the first unbalance mass unit (34) or the second unbalance mass unit (36).
