  • Belt drive
    Patent number: 5012263
    Abstract: The invention is directed to a positively-guided belt drive wherein the drive of the belt by supporting surfaces is decoupled from the drive of the belt via projections. This decoupling is effected with the aid of ball bearings. In a belt drive of this kind, the forces acting on the inner side of the belt are greatly reduced. This leads to reduced wear and to a longer service life. The rate of malfunctions of focal plane shutters of photogrammetric cameras is significantly reduced by this belt drive.
