Screw nut to the torque limitation and use of such a screw nut in a holder module for the clamping force limitation

摘要

Screw nut (18) for limiting the torque, or respectively of the clamping force, which is in the case of a screw connection with a screw (22) on the screwability end component is applied, comprising:– a clamp body (19), which in the case of the screw connection with the component to be screwed in; and– a screw element (20) with an internal thread (21), with which the screw nut (18) on the screw (22) can be screwed;the clamping body (19) and the screw body (20) in the axial direction of the internal thread (21) between an unlocked position and a locking position are arranged so as to be movable,the clamping body (19) and the screw body (20) in the locking mechanism, by means of a form in a positive-locking manner in the engagement with one another,finally, wherein the form of a mechanism with first engaging means (29) of inner cone (27) is provided, which are coaxial or in the through opening (23) of the clamping body (19) is formed, and a second engaging means (30) has external cone (28) is provided, the screw element (20) which surrounds the circumference, and wherein the inner cone (27) and the outer cone (28) in the locked position in such a way into one another, so that the first engaging means (29) and the second engaging means (30) engage into each other in positively locking relationship, andin the event of exceeding a defined clamping force the unlocked position is established, which state transition continuously a restoring force which counteracts.
