Definitions

the present invention relates to a device for fixing of a sleeve on an axis of a plate cylinder of a printing machine.
the deformation of the sleeve is usually obtained by blowing pressurized air between the internal surface of the latter and the outer surface of the tree, through small diameter holes provided in the latter.
the outer surface of the sheath can also be hollowed out, opposite each of the holding surfaces, with a recess whose depth is such that when the sleeve is in assembly position, the outer surface of this next to the holding surface is located substantially in line with its external surface located next to the cavities.
the shaft 1 is hollowed out with a second longitudinal channel 13 which is axial and which also opens at one end of tree 1.
Channel 13 is in communication with five radial conduits 15 which open onto the periphery of shaft 1, in a small cylindrical bowl 17 dimension.
the sleeve 2 is drilled, opposite each conduit 15, an orifice 18.
the shaft 1 is hollowed out by two circular grooves 19 in which are placed O-rings 21.
Another O-ring 21 ' is arranged in a circular groove 19' to the other end of shaft 1.
the sleeve 3 consists in particular of a metal, by example of aluminum. It can also consist of synthetic materials using a structure especially honeycomb, so as to have a large rigidity.
a flow of pressurized air A is then injected through the axial channel 13, so that it passes through the sheath 2 through the orifices 18, and creates, between the surface of the internal wall of the sleeve 3 and the surface of the external wall of the sheath 2, a film of pressurized air which has the effect of repelling the parts of the sheath 2, which are opposite the cavities 7, or deformable parts 25, which allows said subassembly to be easily introduced inside the sleeve 3.
the deformation of the sheath 2 is facilitated by the fact that the volumes V, comprised between the internal walls of each cavity 7 and the internal face of the deformable parts 25 sleeve 2, are maintained at atmospheric pressure by the conduits 9 and the channel 11. In fact, the pressurized air injected through the orifices 18 can not enter these volumes V due to the presence of O-rings 21 and 21 '.
the present invention thus makes it possible to produce a removable locking of a sleeve, and in particular of a sleeve anilox, on its drive shaft, without causing deformation on the upper surface of this sleeve.
this device ensures such blocking, without that it is necessary, during operation, to put using hydraulic pressure maintenance means.
