For heavy loads and quick mounting!
ETP-HYLOC is a hydro-mechanical hub-shaft connection which,
due to its robust design, is ideally suited to work in difficult
environments
and heavy operations like steel rolling mills, process industries etc. An
interesting application, among many, has been fastening of feeding or forming
rolls to shafts.ETP-HYLOC is fast to mount, has good concentricity and can take
high torque and radial loads. Mounting and dismantling is easily carried out
with a hydraulic pump.
Construction
ETP-HYLOC is a hydro-mechanical joint, which consists of a double-walled steel
sleeve which encloses a conical moveable piston. Mounting and dismantling is
carried out with a hydraulic pump.
In the flange there are three threaded connections (”ON”, ”P” and ”OFF”) in the
radial direction and the same in the axial.
This makes it possible to choose radial or axial connection of the pump hoses,
depending on the build-in situation.
Operation
When the piston is moved, by the hydraulic pressure from the pump, the
double-walled sleeve expands uniformly against shaft and hub to form a rigid
joint.
When dismantling, the piston is moved in the opposite direction and the joint
will loosen. A small amount of oil will be taken via spiral tracks in the
piston
between the surfaces (pressure applied through the ”P” connection), in this way
making it easier for the piston to move.
Normal working pressure is 1 000 bar.
