    Abstract: In order to optimize a nut and a method for the production of a nut, comprising a nut body which is provided or can be provided with an internal thread and has a polygonal section with a polygonal outer contour which has, on the one hand, edge areas and, on the other hand, key faces which are located between the edge areas and extend in key face planes extending in a manner conforming to standards, in such a manner that it has mechanical properties which are as ideal as possible with as low a weight as possible, it is suggested that the nut body have a plurality of recesses which extend into the nut body in the direction of the bore proceeding from the respective key face planes.

    Abstract: A locking nut comprising at least two nut portions and at least one frangible bridging portion and a method of making a locking nut. The nut portions are made from a single nut. Each nut portion has an outer gripping surface and a centrally disposed threaded aperture for receiving and engaging a screw. The bridging portion is integral with the nut portions and is disposed to a side of the aperture adjacent to the gripping surface. The nut portions are disposed on either side of the bridging portion so that the apertures are axially aligned, the threads are aligned and a space is defined between opposing faces of the nut portions. By applying torque to one of the nut portions relative to the other nut portion, the bridging portion is sheared and opposing faces of the nut portions are brought into contact and the nut portions are locked in place.

    Abstract: A heavy duty press mechanism, whose ram is driven by means of an eccentric crank and pitman, carries a head with four aligned indention punches for distorting thread pitch simultaneously on four axially aligned hex nuts. A feed track system feeds a row of axially aligned hex nuts under the punch head. A reciprocating ejector-stop, synchronized with the punch ram, simultaneously ejects a group of four indented nuts and defines a stop for the following group of nuts at the indention station. A feed system includes an axial feed track for feeding nuts to the indention station, a lateral feed track, and a transfer speed coupler coupling these tracks. A vibrating hopper feeds laterally aligned nuts into the lateral feed track, where a single row of side-by-side nuts is fed by gravity to the speed coupler. The speed coupler effects a transfer from lateral feed to axial feed into the axial feed track. Air jet means initiates the axial feed of nuts in the speed coupler; and a vibrator associated with the speed coupler contributes to the smooth, fast transfer of nuts from lateral feed to axial feed. The indention punches deform the material of one wall of each nut, producing accurately controlled thread deflection into the threaded bores, and also produce a controlled, slight ovaloid shape of the hex nut.

    Abstract: An improved locknut has a hexoganal body with a threaded central opening. The threaded central opening has noncircular lock thread convolutions with a reduced pitch. Standard thread convolutions are disposed adjacent to the bottom of the opening to facilitate engagement with the mating thread. To form the lock thread convolutions, a hexagonal nut is moved through a nip between a pair of rotating externally toothed indenting wheels. As the nut passes through this nip, crest portions of the teeth on the indenting wheels move into engagement with opposite flat side surfaces of the nut body. As the nut body continues to move through the nip, the externally toothed wheels indent the nut body at spaced-apart locations. To promote accurate control of the axial extent of the lock thread convolutions, the external teeth on the indenting wheels have a tooth depth which is greater than the depth of the indentations formed in the opposite sides of the nut. This prevents deformation of the nut body by the root portions of the indenting teeth. The indenting teeth extend at an acute angle to the axis of rotation of the wheels to form the indentations with sloping inner surfaces.

    Abstract translation: 改进的锁紧螺母具有带有中心孔的螺旋体。 螺纹中心开口具有减小间距的非圆形锁螺纹卷积。 标准螺纹卷绕件布置成与开口的底部相邻，以便于与配合螺纹接合。 为了形成锁螺纹卷积，六边形螺母通过一对旋转外齿形压痕轮之间的辊隙移动。 当螺母穿过该辊隙时，凹入轮上的齿的波峰部分与螺母体的相对的平坦侧表面接合。 当螺母体继续移动通过辊隙时，外齿轮将螺母体在间隔开的位置处压紧。 为了促进锁螺纹卷积的轴向范围的精确控制，压痕轮上的外齿的齿深度大于在螺母的相对侧形成的凹陷的深度。 这防止了由凹口的根部产生的螺母本体的变形。 凹入的齿与轮的旋转轴线呈锐角地延伸，以形成具有倾斜的内表面的压痕。
