Title:
【発明の名称】印刷機の回転する部分に圧縮空気を導入するための回転式供給装置
Document Type and Number:
Japanese Patent JPH0720696
Kind Code:
B2
Abstract:
The invention proposes a rotary transfer device for the introduction of compressed air into a rotating part of a printing machine, especially via the end face (3) of the journal (4) of a roller or cylinder, consisting of a rotor (2) which is attached to the rotating part in the direction of the axis (DA) of rotation and on the shaft of which a housing bush (6) is mounted. For each compressed-air conduit to be transferred, pairs of deep groove ball bearings (13) between the shaft of the rotor (2) and the housing bush (6) form an annular chamber (17) which can be supplied with compressed air via a bore (18). The pressure forces sealing washers (19) against the lateral contact faces of the inner and outer races (13.1, 13.2) of these bearings. In unpressurized operation, the sealing washers are held by retention rings (14). The compressed air from the chamber(s) (17) is conveyed via bores (20.1, 20.2) in the rotor (2).
