Gearwheel for driving the cylinders of offset printing machines

摘要

In order to use the actual wheel body of a gearwheel both for partial deformation in the radial direction and for increasing the diameter, convex spreading walls (17, 17') are moulded as a supporting body onto the wheel body, on which spreading walls a multiplicity of tensioning screws acting in the axial direction are mounted, distributed evenly around a circle. <IMAGE>
