Title:
作用トルクを制限するためのねじ付ナット及びそれに対応する方法
Document Type and Number:
Japanese Patent JP2004524493
Kind Code:
A
Abstract:
The present invention relates to a screw nut (10) for limiting an acting torque and a method corresponding thereto. The screw nut (10) has a threaded section (1) and a tubular section (2), where a predetermined breaking point (3) is arranged between the threaded section (1) and the tubular section (2), and where the threaded section (1) has a first shoulder structure (6) for a wrench and the tubular section (2) has a second shoulder structure (7) for an additional wrench. The screw nut (10) according to the invention preferably consists of a synthetic material, in particular of a polymer such as polyamide. This has the advantage that particularly the region of the predetermined breaking point (3) may consist of a material differing from, in particular softer than, the threaded section (1) and/or the tubular section (2), and therefore a defined torque limitation is obtainable not only via the geometry of the predetermined breaking point (3) but also or exclusively via selectively processed material of suitable quality.
