Clamping Unit KE … FHK spring activated – hydraulically released Features Clamping Unit Spring activated Hydraulically released For piston rod diameter from 12 mm to 115 mm Example for ordering Clamping Unit KE 037 FHK with piston rod diameter 16 mm: KE 037 FHK - 016 Description The Clamping Unit KE … FHK clamps and holds hydraulic cylinder drawbars with a calculated clamping force in both directions of movement. The clamping force is generated via built-in disc springs. The Clamping Unit is released by hydraulic pressure. The units are fitted to cylinders and other machine parts with a connecting flange by the customer. When the pressure on the Clamping Unit is removed, the force of the springs work fully onto the piston and therefore also on to the disc pack. The clamping discs translate the axial spring pressure into a radial force applied to the slotted clamping sleeve that is equal to at least five times the axial pressure. The clamping sleeve transmits the radial clamping forces to the piston rod, thereby holding the piston rod firmly in place. Operation During the working stroke of the hydraulic cylinder, pressure is exerted onto the Clamping Unit. Through this pressure the disc springs are compressed via the piston. In this position, the clamping discs are free of axial tension and thus allow the piston rod to move freely. Application The Clamping Unit secures the piston rod with precision against unintentional axial movements. For example, on machines with cylinders or linear motors a certain position can be driven in one continuous movement. With the Clamping Unit this position can then be held mechanically with accuracy. The accuracy of the safety Clamping Unit is independent of the size and the direction of the force on the piston rod up to the maximum Each time the pressure falls – even when this was not planned – the Clamping Unit will respond immediately. Features holding force indicated. No movement of the piston rod is required for the holding force to become effective; the clamping force is effective immediately and does not depend on outside forces. If it is necessary to brake the movement of the piston rod, the Clamping Unit would, when pressure falls, produce virtually without delay a constant friction force independent of time. The slowing down of the piston rod is therefore even and protects the decelerated components of the installation. • For continuous piston rod clamping • Spring activated, hydraulically released • Holding forces transmissible in both directions of movement • No application of force (lifting) to the piston rod requi
