Corrosion resistantand easy to clean
The demand from the food andprocess industries is increasing for stainless steel hub-shaftconnections. The most common sizes of he hydraulic connection ETP-EXPRESS are available in stainless steel. The flat flange design allows for easy cleaning,essential within food processing.
Also the pressure medium and screwlubricant are approved for use in the food industry.
Small built-in dimensions and one radial screw
In this cleaning system for workpieces in the automobile industry,ETP-EXPRESS R is used for fastening of the brushes. The minimal built-indimensions, radial tightening, good runout (less vibrations), moderate surfacepressure with thin hubs (a bearing outside the hub) and resistance to frettingcorrosion were important factors. Also the quick change of brushes was a benefit.
A through going shaft in a gearbox is locked in both ends with ETP-EXPRESS R.The gearbox drives a mixer for food. Also the pump wheel in the mixer is lockedwith ETP-EXPRESS R, which fulfills the requirements to be approved for use infood environment. The good corrosion resistance, the quick mounting and ease of cleaning are appreciated features.
Frequent mounting, sealing function
In this ”column” for manufacturing of medicines ETP-EXPRESS R is used tomake sure that the piston is locked in an exact position vertically. The design is compact with a thin hub and a hollow shaft, at the same time the moderate and even surface pressure in both directions have a sealing function. Frequent adjustments, approval to be used in food environment, ease of cleaning are other important factors.
Exact and quick axial positioning
In this test machine for static and dynamic strength of for example skeleton parts,ETP-EXPRESS R is used for adjustment and locking of the lower shaft to which the parts are fixed. Positioning is important and is made easily as no axial movement takes place when the screw is tightened. Change of test specimen is made quickly as only one screw has to be operated. The surface of the shaft will not be damaged, even when frequently mounted, because of the even andmoderate surface pressure.
Ease of mounting/adjustment
Two parallel chains drive this packaging machine for food. Adjustment of the chains, relative each other, and location of the chain hubs in position along the shafts are made easy when ETP-EXPRESS R is used. Adjustments are easily done later as only one screw needs to be loosened/ tightened.
Accurate positioning,adjustments, good runout
The gears in this food machine are accurately adjusted during assembly with ETP-EXPRESS R to avoid backlash and noise. After a certain time wear makes adjustment necessary, this is done easily as only one screw needs to be loosened/tightened. Also the good runout helps to reduce the noise level and vibrations.
ETP-EXPRESS R is available as standard for shafts 15-80 mm, also imperial. Runout ≤ 0,02 mm. Number of mountings 200 – 800 (size dependent). The extremely thin built-in dimensions allows for a compact design with low weight and inertia.
ETP-EXPRESS R is a hydraulic connection which consists of a double-walled hardened stainless steel sleeve filled with a pressure medium, and a flange. The flange part contains a stainless screw and piston with seals to maintain pressure.
When the pressure screw is tightened the double-walled sleeve expands uniformly against shaft and hub and creates a rigid joint. Dismantling is done by loosening the screw. ETP-EXPRESS R returns to its original dimensions and can easily be dismantled.
Benefits and features
