Roll for use in calenders and the like |
摘要 |
A roll for use in a calender has a stationary carrier for a hollow cylindrical shell whose end portions are supported by combined radial and axial bearings surrounding annular bearing members which, in turn, surround the end portions of the carrier. The carrier defines with each bearing member a set of chambers which are sealed from the atmosphere and can receive pressurized hydraulic fluid to ensure that the end portions of the shell are biased toward a second roll with a requisite force as well that the end portions of the shell are stabilized against lateral and/or other stray movements. The fluid in the chambers ensures that the shell can be acted upon by large forces without unduly stressing the antifriction bearings. The bearing members flank a hydrostatic bearing unit which acts between the central portion of the shell and the carrier.
