摘要： The invention relates to a worm shaft (10) comprising a first component (12) which bears a screw flight (14) and which has a first worm shaft end, and a second component (18) which has a second worm shaft end, wherein the axial extension (A) of the worm shaft (10) is defined by the spacing of the first worm shaft end from the second worm shaft end, wherein the axial extension (A) is fixed by connecting the first and second components (12, 18) at a predefined spacing by means of a connection member. The invention is characterized in that the axial extension (A) of the worm shaft (10) is set by the axial extension (A) of the connection member.

摘要： The invention relates to a connection element for an interlocking connection to at least one component. The at least one component is held between the connection element and a securing element, and the connection element and the securing element enter into a friction welded connection, having a head with a drive and a shaft, wherein the shaft has at least two cutting structures on its front side. The at least two cutting structures have cutting edges situated in a cutting plane, wherein the cutting plane borders the shaft, and the at least two cutting structures are also spaced apart in the circumferential direction and define a cutting diameter. The shaft also has a cross-section, which has a reduced extension between the cutting structures relative to the cutting diameter, wherein the area of the reduced extension extends in the axial direction at least with the length of the cutting diameter from the cutting structures in the direction of the head.

摘要： A securing element includes a threaded region, wherein a securing rotational direction and an axial clamping direction are defined by the thread design. The securing element has a head with a head lower face which faces the clamping direction and via which a force-fitting connection with a component can be produced. The head is designed such that the head lower face has an edge region at a radial distance from the head center, and the contour of the head lower face runs opposite the clamping direction in the direction of the head center starting from the edge region, whereby a spring effect can be produced. The edge region has a changing circumferential level in the axial direction. Opposite the securing rotational direction, the circumferential level rises at a rising angle of maximally 15° in the clamping direction over a central angle of at least 65°.
