摘要： A loosening prevention structure for a bolt and nut, having a bolt, a nut member screwed on the bolt, and a lock nut. The nut member has a lock nut engagement portion formed in a tapered manner toward axially one end of the nut member. The lock nut engagement portion has, on its outer surface, an external screw having a thread direction same as or reversed to that of an internal screw on its inner peripheral surface and also has a slit extending toward the axially one end of the nut member.

摘要： A self-locking nut includes a main-nut body and a deformable-nut body. The main-nut body has a recess leading into an interior threaded bore forming x turns of an internal thread therein. The deformable-nut body has an outer flange and an interior threaded bore forming y turns of an internal thread therein. The outer flange of the deformable-nut body is fixed to the main-nut body such that a relief space is formed between the deformable-nut body and the recess. A ratio of x:y is about 2:1.

摘要： Die Erfindung bezieht sich auf eine Doppelmutter (1) mit einer Flanschmutter (2) und einer Einlegemutter (3). Dabei weist die Flanschmutter eine Längsachse und in einem der Einlegemutter zugewandten Endbereich eine Anschlag- (24) und eine Wandfläche (25) auf. Die Einlegemutter weist eine Längsachse und in einem der Flanschmutter zugewandten Endbereich ein Schnappelement (35) auf. Zudem übergreift die Anschlagfläche das Schnappelement radial in Richtung der Längsachse der Flanschmutter. Die Erfindung sieht vor, dass die Flanschmutter eine Führungsfläche (26) im der Einlegemutter zugewandten Endbereich aufweist, wobei die Führungsfläche näher zur Längsachse der Flanschmutter angeordnet ist als die Wandfläche.
摘要翻译：提供了一个双螺母，其中法兰螺母和插入螺母联接在一起。凸缘螺母具有纵向轴线，并且在面向插入螺母的端部区域中具有止动表面和壁表面。插入螺母具有纵向轴线并且在面向凸缘螺母的端部区域中具有至少一个卡扣元件。止动表面在法兰螺母的纵向轴线的方向上径向延伸至少一个卡扣元件。凸缘螺母在面向插入螺母的端部区域中具有引导表面，该引导表面比壁面更靠近凸缘螺母的纵向轴线设置。
