Embodiment Construction

[0026] figure 1 A printing press 10 is disclosed, the printing press 10 shown in this example being a flexographic printing press.

[0027] The printing press 10 includes an anilox roll 12, a first printing cylinder 14, which may also be referred to as a plate cylinder, and a second printing cylinder 16, which may also be referred to as an impression cylinder.

[0028] The printing press 10 is configured for printing on a substrate 18 using a known flexographic printing method according to which an anilox roller 12 transfers ink from an ink tank (not shown) to a first printing cylinder 14. The first printing cylinder applies the ink to a substrate 18 supported by a second printing cylinder 16 .

[0029] The anilox roll 12 is rotatable about an axis of rotation 12 a and comprises a shaft body 12 b which is rotatably supported in a carrier element 20 of the printing press 10 .

[0030] The first printing cylinder 14 is rotatable about an axis of rotation 14 a and has a shaft ...

Abstract

A bearing assembly (26) is described. It is suitable for supporting a printing cylinder or an anilox roll in a printing machine and comprises at least one roller bearing (28, 30) being configured for receiving a shaft (12b, 14b, 16b) associated with the printing cylinder or the anilox roll. Additionally, it has a first support part (32) carrying the roller bearing (28, 30) and a second support part (34) being a carrier element of the printing machine or being configured for being mounted to a carrier element of the printing machine. Furthermore, a fluid chamber (36) is provided acting between the roller bearing (28, 30) and the second support part (34). Moreover, a printing machine is presented wherein a shaft (12b, 14b, 16b) associated with a printing cylinder or an anilox roll thereof is supported by such a bearing assembly (26).

Description

technical field [0001] The invention relates to a bearing assembly for supporting a printing cylinder or anilox roll in a printing press, comprising at least one roller bearing configured to receive a The shaft associated with the roller. [0002] Furthermore, the invention relates to a printing machine comprising a printing cylinder and / or anilox roll, wherein a shaft associated with said printing cylinder and / or anilox roll is supported in said printing machine by such a bearing assembly . [0003] Herein, the shaft associated with the printing cylinder or the anilox roller may be a shaft directly or indirectly connected to the printing cylinder or the anilox roller, respectively. Indirect connections may include transmissions or drive mechanisms. Background technique [0004] Most printing methods result in vibrations which are generally undesirable. This shock has to be at least partially absorbed by the bearing assembly in order to allow high quality printing result...
