Roller bearing for rollers of rotary printing machines

摘要

The invention relates to a roller bearing for rollers of rotary printing machines, in particular for inking-unit rollers, provided for the two-point bearing of the rollers on both sides of a roller. The invention is based on the object of proposing a roller bearing which completely surrounds axle journals of the roller, brings them into a defined position and secures them, absorbs forces and moments and can be closed and opened without using tools. According to the invention, the object is essentially achieved in that bearing bushes (4, 5) are provided for receiving rolling bearings (3), in that the rolling bearing (3) is fixed axially in each case by means of annular grooves (6, 7) and securing rings (8), in that in each case two sleeves (12, 13) arranged one inside the other are provided, in that the sleeve (12) arranged on the inside is mounted on a bearing journal (15) arranged in each case in the frame wall (14) so as to be secure against rotation and displacement, and the sleeve (13) arranged on the outside is rotatably mounted, fixed axially on the sleeve (12) arranged on the inside, in that the sleeves (12, 13) are each designed to be divided in half longitudinally in the region which is remote from the frame, in that in each case both sleeves (12, 13) arranged one inside the other completely receive one of the two bearing bushes (4, 5), and in that the bearing bushes (4, 5) and the part of the sleeve (13) arranged on the outside and divided in half longitudinally and the bearing bushes (4, 5) and the part of the sleeve (12) arranged on the inside and divided in half longitudinally in each case form a fitting piece. <IMAGE>
