Video Description Product Description

For the HS high speed diaphragm coupling, the flexible elements adopt AISI 301 or high nickel alloy steel, the tensile strengh reaches as high as 150-170kgf. Computing on 10000RPM, the fatigue life can reach 20 years. The other components adopt AIS 4140 or equivalent high strength light alloy. Therefore, this coupling has ligh weight, superior axial rigidity and torsional strength etc mechanic properties. It has the outstanding features such as protecting the unit output shaft, extending the unit service life ect.

The shaft flange and the intermediate flange are the mutually lapping pawl structure. It can effectively prevent the broken pieces from flying out, and can urgently transfer the torque.The outside smooth circumferential face of the flexible element has effectively reduced wind drag at high speed rotation.The intermediate has several layers of stainless steel sheet, which can adjust the axial clearance.

It is suitable for the motor (gear speed-increasing) steam turbine, gas turbine, expander, rotary motor, blower, electric generator, tester, high speed pump etc high speed unit, especially suitable for the power transmission of the centrifuger, turbo compressor, shipping propeller etc.

On the basis of the ordinary type high speed diaphragm coupling, combining the site application practice, our factory has designed and developed the protective type and guard tooth multi-joint type high speed diaphragm coupling one after another. Through actual application examination over years, the site reflection is good. It is the most reliable choice of the high speed diaphragm coupling.
