Bearer ring-press cylinder connection construction for rotary printing machine
First Claim
1. In a rotary printing press,a bearer ring (1) - press cylinder (7) connection construction, in which the bearer ring (1) is mounted on the shaft (5) of the cylinder for rotation therewith and positioned against an end face of the cylinder, the shaft passing through the bearer ring,and wherein, in accordance with the invention,the engagement surfaces (9, 11) of the shaft and of the bearer ring are axially bowed or rounded to form, respectively, matching concave-convex engagement surfaces to permit slight floating alignment of the bearer ring with respect to the axis of rotation of the respective printing cylinder and tilting of the plane of rotation of the bearer ring with respect to the direction of the axis of rotation of the shaft in the region of said engagement surfaces.

Abstract
To provide for engagement between adjacent bearer rings throughout their entire engagement line or surface, in spite of slight misalignment or tilting of the actual axis of rotation of the shaft of the printing cylinder with which the bearer ring is associated, the bearer ring is located on the shaft of the printing cylinder with a slightly spherical engagement surface, preferably by attaching a hub to the shaft having a slightly convex outer surface which matches a slightly concave inner surface of the bearer ring. Preferably, a shock-absorbing, wear-resistant elastic material is interposed between the respective engagement surfaces. To permit alignment of the bearer ring with respect to the cylinder, and exact concentricity, eccentric alignment pins are provided, engaging the bearer ring and the end face of the printing cylinder, at least three such attachment arrangements being located circumferentially on the end face of the printing cylinder, and bearer ring, respectively.
