Controlled deflection roll drive

Claim 2

A driven roll construction comprising in combination, a roll shell, support bearing means carrying the roll shell for rotation, an extension ring having an annular driving ring gear and being on an end of the roll shell for driving the shell, a drive pinion gear positioned radially outwardly of the ring gear and in mesh therewith for rotationally driving the roll shell, a pinion support member rotatably supporting said pinion and having a portion positioned radially inwardly of the extension ring, and a bearing between the extension ring and support member portion.

Claim 3

A driven roll construction in accordance with claim 1 wherein said bearing is located in substantial radial alignment with said ring gear.

Claim 4

A driven roll construction in accordance with claim 1 wherein said pinion support member includes a housing surrounding said pinion gear.

Claim 5

A driven roll construction in accordance with claim 1 wherein said roll shell includes a stationary shaft extending through the roll shell and force transmission means at one side of said shaft between the roll shell and shaft having fluid force transmitting means for applying an equal pressure along the axial length of the roll shell.

Claim 6

A driven roll constructed in accordance with claim 1 wherein said roll shell includes a stationary shaft extending therethrough with a shoe slidably supporting the roll shell on the shaft and a fluid piston and cylinder means supporting the shoe on the shaft for carrying the roll shell with a uniform force along its axial length.

Claim 7

A driven roll construction in accordance with claim 1 wherein said ring gear is carried on an extension ring on the end of the roll shell and said bearing is located between saId extension ring and said pinion support member.

Claim 8

A driven roll construction in accordance with claim 1 including a flexible coupling drive for said pinion gear.

Claim 9

A driven roll construction in accordance with claim 1 wherein said pinion support member includes bearings at each end of said pinion gear.

Claim 10

A driven roll construction in accordance with claim 1 wherein said pinion support member includes a housing for the pinion gear with an oil seal between the extension ring and housing for maintaining lubricant between said pinion gear and ring gear.

Claim 11

A driven roll construction comprising in combination, a roll shell, a stationary shaft extending through said roll shell, deflection control means between the roll shell at one side thereof and the shaft and including a fluid force transmission means for transmitting the load from one radial location of the roll shell to the shaft, a self-aligning bearing between the shaft and roll shell, an annular driving ring gear on an end of the roll shell for driving the shell, a drive pinion gear positioned radially outwardly of the ring gear and in driving mesh therewith for rotationally driving the roll shell, a pinion support member rotatably supporting said pinion gear and having a portion extending axially within the ring gear, and a bearing between the ring gear and said support member for stabilizing the relative positions of the gears.

Claim 12

A driven roll construction comprising in combination, a roll shell, a stationary shaft extending through said roll shell, deflection control means between the roll shell at one side thereof and the shaft and including a fluid force transmission means for transmitting the load from one radial location of the roll shell to the shaft, a self-aligning bearing between the shaft and roll shell, an annular driving ring gear on an end of the roll shell for driving the shell, a drive pinion gear positioned radially outwardly of the ring gear and in driving mesh therewith for rotationally driving the roll shell, a pinion support member rotatably supporting said pinion gear and having a portion extending axially within the ring gear, and a bearing between the ring gear and said support member for stabilizing the relative positions of the gears.
