Embodiment Construction

[0013] exist figure 1 with figure 2 A bearing arrangement for a shaft 1 of a printing technology machine is shown in . exist figure 1 A longitudinal section of the shaft 1 and bearing assembly is shown in , and in figure 2 A cross section of a bearing housing 19 of a bearing arrangement without a shaft is shown in . Printing technology machines are sheet printing presses for lithographic offset printing. Shaft 1 is a gripper shaft with a row of sheet gripper fingers 18 arranged thereon for gripping a printed sheet conveyed in the printing press. A bore 4 is provided in the bearing housing 19 , the central axis of which is coaxial with the shaft 1 .

[0014] The bearing housing 19 comprises an upper part 2 and a lower part 3 . The two parts 2 , 3 are joined together at the parting seam 5 . The boundary seam 5 is a fracture boundary line extending irregularly, and the fracture boundary line is produced by cracking or cracking (or fracture-splitting). The upper part 2 c...

Abstract

A bearing arrangement for a shaft (1) of a printing technology machine comprises a bearing housing consisting of an upper part 2 and a lower part 3. The bearing housing has a bore for receiving a rolling bearing (20) for the shaft (1). The upper part (2) and the lower part (3) are separated by a parting seam which is located in the region of the hole. The rolling bearing is an axial bearing having at least one rolling element ring and at least one annular rotating disc. The rotating disk (8) is clamped between the upper part (2) and the lower part (3), which are pressed radially onto the rotating disk (8) on the outer peripheral surface.

Description

technical field [0001] The invention relates to a bearing arrangement for a shaft of a machine in printing technology, comprising: a bearing housing consisting of an upper part and a lower part; a hole in said bearing housing for receiving a rolling bearing for said shaft ; wherein the upper part and the lower part are separated by a boundary seam, the boundary seam being located in the region of the hole. Background technique [0002] Printing technology machines include printing machines and post-processing machines in which printed sheets are post-processed. Gripper systems are used in printing technology machines, with which the sheets are held in place during their transport. The gripper system can be arranged on a conveyor roller or a chain conveyor. This gripper system comprises gripper fingers and gripper holders arranged in pairs with each other. The sheets are clamped between the corresponding gripper finger and the associated gripper holder. The gripper finger...
