Clamping element

example, it is very important that the eccentricity between
pitch circle and seating bore is very small.
For this purpose the diaphragm clamping system SM is
used. For machining the seating bore it allows clamping of
the gear wheel at the pitch circle.
The clamping element is a ring disk with primarily three
clamping jaws. If the workpiece is thin-walled the diaphragm
can also have four or six clamping jaws. These are either
carved out of the diaphragm or they are screwed onto it.
By applying an axial force onto the diaphragm, it bends in
direction of the force. The clamping jaws simultaneously
move axially and open in radial direction. The gear wheel is
being released.
Due to its flexibility the diaphragm returns to its initial position
if the axial force is reduced or taken away. The gear
wheel is being clamped in axial and radial direction.
