Embodiment Construction

[0016] The shown bearing system 10 includes a bearing housing 11, and the outer ring 12 of the rolling bearing is flanged in the axial direction and connected to the bearing housing 11 on the fixed plane B1. Because the rolling bearing outer ring 12 is axially flanged on the bearing housing 11 , machining-induced tolerances of the components have no effect on the bearing play of the bearing system. Fixing screws 14 are provided for fixing the fixed bearing outer ring 12 to the bearing housing 11 . Boreholes 15 running parallel to the longitudinal axis A of the drum or roller are provided on the rolling bearing outer ring 12 at the same radial distance from the longitudinal axis A of the drum or roller to accommodate the fastening bolts 14 . However, based on the thick-walled structure, the outer ring has high shape stability. The outer ring 12 carries rolling bodies 13 guided by a retaining ring on the inner circumferential side, the rolling bodies 13 having a cylindrical des...

Abstract

The invention relates to a bearing system for a printing press and the printing press. The bearing system can support a free end of a cylinder or roller with one end being hung on the printing press, especially a flexographic press and as a journal, wherein, the bearing system comprises a bearing housing which is moved transversely to a cylinder and roller longitudinal axis or slided parallely to a cylinder and roller longitudinal axis and a roller bearing, the roller bearing has a roller bearing outer ring and a cage-guided roller body. According to the invention, the roller bearing outer ring is connected with the bearing housing in the fastening planes aligned transverse to cylinder and longitudinal axis in force and positive-fit manner and the journal of the cylinder or roller is formed into a roller bearing inner ring. Alternatively, a single roller bearing inner ring can be arranged, and the roller bearing inner ring can be connected with the journal in force and positive-fit manner.

Description

technical field [0001] The invention relates to a releasable and displaceable bearing system having the features stated in the preamble of claim 1 for cylinders or rollers on a printing press, in particular a flexographic printing press, which are suspended at one end, The free end formed as a journal is supported. Furthermore, the invention relates to a printing machine, in particular a flexographic printing machine, having such a bearing system. Background technique [0002] On printing presses, in particular flexographic printing presses, the image to be printed is changed by changing the sleeve of the printing cylinder carrying the relief plate, the so-called "sleeve". In order to be able to change the sleeve, each printing cylinder or each roller must be freely accessible at least temporarily at one end. Therefore, such drums or rollers are generally supported in the air at one end. That is to say, the end of the free bearing is provided with a bearing system for rec...
