A chain drive unit (4, 5, 6) for reducing chain vibrations comprising a chain wheel unit (43) with at least two sprockets (431, 432) that are arranged parallel on a common rotation axle, at least two parallel chains (51, 52) engaging these sprockets (431, 432). At least one damping element (6) connecting two adjoining chains (51, 52). The circumferential orientation of two adjoining sprockets (431, 432) differs by a partial pitch (pP) and the damping element (6) comprises a first fixation (61) on its one free end for the lateral fixation to the first chain (51), a second fixation (62) on its opposite free end for the lateral fixation to the second chain (52) and a force transmission unit (63, 8, 9) arranged between the first and the second fixation transmitting an applied force from the first fixation (61) to the second fixation (62) and vice versa.
A chain drive unit for reducing chain vibrations comprising a chain wheel unit with at least two sprockets that are arranged parallel on a common rotation axle, at least two parallel chains engaging these sprockets, characterized in that at least one damping element connecting two adjoining chains and in that the circumferential orientation of two adjoining sprockets differs by a partial pitch, and in that the damping element comprises a first fixation on its one free end for the lateral fixation to the first chain, a second fixation on its opposite free end for the lateral fixation to the second chain and a force transmission unit arranged between the first and the second fixation transmitting an applied force from the first fixation to the second fixation and vice versa.
A damping element to be used in a chain drive unit, wherein the damping element comprises a first fixation on its one free end for the lateral fixation to the first chain, a second fixation on its opposite free end for the lateral fixation to the second chain and a force transmission unit arranged between the first and the second fixation transmitting an applied force from the first fixation to the second fixation and vice versa.
A method for reducing chain vibrations within a chain drive unit comprising:
