Title:
COUPLING FOR DIRECTLY TRANSMITTING ROTATION MOVEMENT OF OPERATION BOLT TO CLAMP JAW DRIVEN BY OPERATION BOLT IN PARALLEL THEREWITH
Document Type and Number:
Japanese Patent JP2012082960
Kind Code:
A
Abstract:

To provide a coupling having at least one clamp jaw.

The coupling comprises the clamp jaw adapted to be mounted to a first element to couple the clamping jaw to a second element by clamping the second element against first element, the clamping or releasing of the second element resulting from translational movement following an axis, the clamping jaw comprising a bore having a threaded part forming a nut in which an actuation bolt defining the axis is engaged and can drive the clamping jaw in translation following the axis. The coupling is characterized in that a torque limitation means making the actuation bolt engaged with the clamping jaw allows the transmission of the rotational movement of the actuation bolt directly to the clamping jaw by means of the bore of the clamping jaw, and consequently, allows the driving of the clamping jaw in rotation about the axis.
