Printing machine cylinder mount

Claim 2

In a printing machine, a cylinder, a mounting having means for confining the axial displacement of the cylinder, the combination comprising an inner bearing member, an outer bearing member which is rotatable relatively to the inner bearing member and has a mounting constituting part of a printing machine cylinder, a plurality of recesses provided in one of the bearing members on a surface in the space between the inner and outer bearing members, a liquid passage leading to said recesses including restriction means, a liquid passage leading from said recesses, and means continuously circulating liquid through said liquid passages and between the bearing members into said recesses whereby the liquid provides a support for the one bearing member relative to the other.

Claim 3

A printing machine cylinder mounting as claimed in claim 1, wherein the printing machine cylinder mounting further comprises a frame and a mechanism for controlling the axial displacement of the printing machine cylinder relative to said frame.

Claim 4

A printing machine cylinder mounting, comprising a cylinder, means for confining axial displacement of the cylinder, an inner bearing member, an outer bearing member which is mounted on and coaxial with and rotatable relative to the inner bearing member and which comprises part of said printing machine cylinder, a plurality of recesses in the exterior peripheral surface of the inner bearing member between the bearing members, a flow passage for liquid including restricting means situated in the inner bearing member and in communication with the plurality of recesses, and at least one return passage from said recesses situated in inner bearing member, means continuously circulating liquid through the flow passage, the restricting means, the plurality of recesses, and at least one return passage so that the liquid provides a support for the outer bearing member relative to the inner bearing member.

Claim 5

A printing machine cylinder mounting, comprising a cylinder, means for confining axial displacement of the cylinder, an inner bearing member, an outer bearing member which is mounted on and coaxial with and rotatable relative to the inner bearing member and which comprises part of said printing machine cylinder, a plurality of recesses in the exterior peripheral surface of the inner bearing member between the bearing members, a flow passage for liquid including restricting means situated in the inner bearing member and in communication with the plurality of recesses, and at least one return passage from said recesses situated in inner bearing member, means continuously circulating liquid through the flow passage, the restricting means, the plurality of recesses, and at least one return passage so that the liquid provides a support for the outer bearing member relative to the inner bearing member.

Claim 6

A printing machine cylinder mounting claimed in claim 3, wherein the plurality of recesses in the exterior peripheral surface of the inner bearing member are arranged in at least one annular band around the circumference of the exterior peripheral surface of the inner bearing member and wherein each of the recesses is connected to the flow passage by one of the restricting means.

Claim 7

A printing machine cyliNder mounting as claimed in claim 4, wherein said annular band of recesses is adjacent a single annular recess around the exterior peripheral surface of the inner bearing member, and wherein said single annular recess is connected to at least one return passage.

Claim 8

A printing machine cylinder mount comprising in combination, a frame, an axle member, means in said frame for mounting said axle member nonrotatably, a printing machine cylinder mounted concentrically about said axle to rotate thereabout means confining the axial displacement of said cylinder, structure providing a recessed pocket between said axle and said cylinder capable of maintaining a fluid under pressure for supporting the position of said axle within said cylinder, a fluid flow path into and out of said recessed pocket, a restriction is said flow path outside said recessed pocket, and means supplying continuous fluid flow into said pocket at such pressure that the cylinder tends to be held in an optimal position relative to said axle member by means of relative pressures at said pocket and said restriction.

Claim 9

A printing machine cylinder mount comprising in combination, a frame, an axle member, means in said frame for mounting said axle member nonrotatably, a printing machine cylinder mounted concentrically about said axle to rotate thereabout means confining the axial displacement of said cylinder, structure providing a recessed pocket between said axle and said cylinder capable of maintaining a fluid under pressure for supporting the position of said axle within said cylinder, a fluid flow path into and out of said recessed pocket, a restriction is said flow path outside said recessed pocket, and means supplying continuous fluid flow into said pocket at such pressure that the cylinder tends to be held in an optimal position relative to said axle member by means of relative pressures at said pocket and said restriction.

Claim 10

A printing machine cylinder mount as defined in claim 6 wherein said means confining the axial displacement includes means holding said cylinder axially in a predetermined position on said axle relative to said frame.
