Abstract
A roll-journal bearing mounting is provided by a movable bearing housing from which pistons rigidly extend in opposite directions into cylinders rigidly fixed against displacement. Introduction of pressurized fluid to the cylinders moves the bearing housing either way in the direction of the pistons and cylinders. Consequently, a roll journaled by bearings in the bearing housings of two of the mountings can be moved towards and from a counter roll to apply roll nip pressure. At the same time the rigidly extending pistons in their rigidly fixed cylinders also function to hold the journal loading in a right angular direction, eliminating the need for the use of separate devices for that purpose.
Claims10
A roll-journal bearing mounting comprising cylinders having interfacing and interspaced open ends, holding means for holding said cylinders against displacement, a movable bearing housing spaced between said ends, and pistons rigidly connected to said housing so as to extend therefrom respectively in opposite directions and into said open ends of the cylinders, the ends of said cylinders opposite to their said open ends being closed so that pressurized fluid can be fed into the cylinders behind said pistons so as to cause movement of the housing and pistons either way in the directions said pistons extend from said housing in said cylinders.
