Features

Principle
This flexible shaft coupling utilises a cruciform intermediatebody to transmit power even when the angular misalignment
between the two shafts is particularly large.
Misalignment
Allow angularsingle
doubleAllow lateral and angular
Allow lateral and angular, endplay

telescopic

Hub-Shaft Connection
Cross-pinning
Fastening by drilling a bore slightly smaller than the outer
diameter of the pin and press-fitting the cross-pinning into the bore
Set screw
Fixes a shaft by digging sets crews into the shaft directly
Fail-safe
resin

Breaking during excessive torqueshuts off the torque between thedriven and driven

Topology
There is a phase difference between the driven
and driven phases. Even in the case of a double,
there is in principle no phase difference if theintermediate shaft has a symmetrical shapeand the angles with the driven and driven shaftson their quantity side are not exactly equal.
However, because of the spring constantin the direction of rotation. The phase difference depends
on the rotation speed and the torque to be transmitted.
BacklashZero backlash
about 2 degrees at the telescopic section
