Abstract
A transmission device for a printing machine having an endless transmission element, and rotating bodies around which the transmission element is wrapped, includes a tensioning device for tautening the transmission element, and an actuating device for displacing a first one of the rotating bodies parallel to the axis of rotation thereof, the tensioning device being formed by the actuating device, the actuating device having a tensioning shaft operatively connected to the first rotating body, the tensioning shaft, when rotated about a longitudinal axis thereof, causing a lateral displacement of a center-of-mass line thereof.
Claims7
A transmission device for a printing machine, comprising:
- an endless transmission element;
- a longitudinal guide;
- rotating bodies around which said transmission element is wrapped, a first one of said rotating bodies being rotatable mounted in said longitudinal guide;
- a tensioning shaft being pivotable around a longitudinal axis, said tensioning shaft displacing said first one of said rotating bodies along said longitudinal guide and changing an axial spacing between said first one of said rotating bodies and a second one of said rotating bodies when said tensioning shaft is pivoted around it's longitudinal axis.
A sheet-fed printing machine, comprising:
- a printing unit;
- a sheet transporting device supplying sheets to said printing unit, said sheet transporting device having a transmission device including:
- an endless transmission element;
- a longitudinal guide;
- rotating bodies around which said transmission element is wrapped, a first one of said rotating bodies being rotatably mounted in said longitudinal guide;
- a tensioning shaft being pivotable around a longitudinal axis, said tensioning shaft displacing said first one of said rotating bodies along said longitudinal guide and changing an axial spacing between said first one of said rotating bodies and a second one of said rotating bodies when said tensioning shaft is pivoted around it's longitudinal axis.
