Problems solved by technology

In addition, machining-induced tolerances occur which further increase the radial play
However, this bearing clearance adversely affects the printing quality

Embodiment Construction

[0020]From this longitudinal section, firstly a bearing system 10 can be seen, which comprises a first housing part 11 and a second housing part 12 guided axially in the first housing part 11 . The two housing parts 11 , 12 have, corresponding to one another, conically extending circumferential regions 11 . 1 , 12 . 1 for forming the axial joint. On the conically distributed inner peripheral region 11.1 of the first housing part 11, a cylindrical inner peripheral region 11.2 is attached, which surrounds a cavity which, when a suitable force is applied, can push the second housing part 12 is pulled back into the cavity. The force is applied by means of a pneumatically actuatable piston 19 which is rigidly connected via a piston rod to the second housing part 12 and which is accommodated in a piston housing 21 which in turn is fixed to the first housing part 11 connect. Here, the piston housing has a radially protruding end plate 24 in which bores are provided for receiving fa...

Abstract

The present invention relates to a bearing system of a printing machine and the printing machine thereof. The bearing system is used for supporting a roller which is suspended and supported at one end of a flexo printing machine or a free end of a roller, which is composed as a shaft journal, wherein, the bearing system comprises the following components: at least one first housing which can move transversely with a longitudinal axis of the roller or the shaft, a second housing which can move parallelly with the longitudinal axis of the roller or the shaft in the first housing, and a rolling bearing. The rolling bearing comprises an outer ring which is connected with the second housing through a force matching and / or shape matching mode, and rolling members guided by a protecting ring. The rolling members roll on an inner ring formed by the shaft journal or rolls on a single component which is connected with the shaft journal through force matching and / or shape matching when the printing is performed, and therefore the outer ring of the rolling bearing can move parallelly with the longitudinal axis of the roller or the shaft relatively to the inner ring. Furthermore, the invention relates to a printing machine with the bearing system, particularly the flexo printing system.

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 such printing presses, in particular flexographic printing presses, the image to be printed is changed by changing the printing cylinder sleeve carrying the relief plate, the so-called “sleeve”. In order to be able to change the sleeve, the respective printing cylinder or the respective roller must be freely accessible at least temporarily at one end. Therefore, such cylinders 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 ...
