ABSTRACT:
Mechanical drive apparatus for rotating the cylindrical shell of a roll, such as a suction or deflection-compensated roll utilized in paper machines, wherein an elongate member, such as a tubular shaft in the case of a suction roll or a massive axle in the case of a deflection-compensated roll, extends longitudinally through the interior of the shell, including a gear transmission having transmission gears through which rotative power is supplied to the shell from an input shaft thereof includes a support member annular portion disposed around one end of the elongate member so as to support the same, unitary bearing means disposed around the annular portion of the support member, drive gear means rotatably mounted on the unitary bearing means within a housing, apparatus preferably in the form of a coupling sleeve, which interconnects the drive gear means and the roll shell whereby the rotational power is transferred from the drive gear means to the shell in a manner such that changes in position of the roll shell relative to the drive gear means can be accommodated within limits. The transmission gears of the gear transmission are disposed within the same housing as the drive gear means, which housing provides support for the elongate member which extends through the shell interior.
