Drive unit for an elongated oscillating body

摘要

The drive arrangement has crank-rocker mechanisms (21), which are driven over a fixed pivoting angle for generating a non-circular oscillatory motion under automatic reversion of rotation. The adjacent crank-rocker mechanisms of the drive arrangement are arranged pair-wise in a longitudinal section of an oscillating body (20) and are coupled with a common bearing region of the oscillating body by an intermediate link (23).
