Plate mill finishing stand roll latch ring

摘要

A latch ring, chock and drive pod retainer assembly ideally suited for use with a finishing stand roll having a chock located at each of its ends, a drive pod at one of its ends, and a circumferal groove formed at each of its ends. The latch ring assembly is employed for retaining the chocks and the drive pod on their respective ends of the roll. The latch ring assembly includes a plurality of latching arms pivotally mounted within a generally toroidal shaped housing, the latching arms being movable between a latched position, in which the latching arms engage the circumferal groove of the roll, and an unlatched position, in which the latching arms are retracted within the assembly housing to a position in which they are out of engagement with the finishing roll circumferal groove. The assembly is configured such that the latching arms are biased toward their latched positions, the assembly also having a mechanism which is operated to retain the latching arms in their unlatched position for facilitating removal of the latch assembly from the roll when it is desired to remove the drive pod and chocks therefrom.
