Abstract
A connecting assembly for a driveshaft, includes an end toothing at a first component and an end toothing at a second component, wherein the end toothings have teeth and gaps. In an end view, the image of the teeth and gaps at both components, are identical and wherein, starting from corresponding images of the teeth and gaps at both components, there are obtained matching complementary images of the teeth and gaps at the two components in an end view when the components are rotated relative to one another by 90° or 180°.
Claims18
A connecting assembly comprising:
- a first component having an end toothing and a second component having an end toothing, wherein the end toothings each comprise teeth and gaps which are axially inserted into one another and circumferentially engage one another in a clearance-free way and wherein the teeth of the respective end toothings on an outer circumference each comprise outwardly opening circumferential grooves which are delimited by two flanks and which, when the respective end toothings are inserted into one another, together, form a circumferentially extending annular groove in which there is positioned a securing ring on the outside, and wherein the teeth at the first component and the second component, are each positioned within a cylindrical annular space and the gaps are positioned in pairs within two groups of continuous groove tracks which extend at a right angle relative to one another and which each pass through the respective cylindrical annular space twice, and wherein,
- in an end view, images of the teeth and gaps are the same at the first component and the second component, and wherein, starting from the corresponding images of the teeth and gaps at the first and second components, there are obtained matching complementary images at the teeth and gaps at the first and second components in an end view when the components are rotated relative to one another by 90° or 180°.
A connecting assembly comprising:
- a first component having an end toothing and a second component having an end toothing, wherein the end toothings each comprise teeth and gaps which are axially inserted into one another and circumferentially engage one another in a clearance-free way and wherein the teeth of the respective end toothings on an outer circumference each comprise outwardly opening circumferential grooves which are delimited by two flanks and which, when the respective end toothings are inserted into one another, together, form a circumferentially extending annular groove in which there is positioned a securing ring on the outside, and wherein the teeth at the first component and the second component, are each positioned within a cylindrical annular space and the gaps are positioned in pairs within two groups of continuous groove tracks which extend at a right angle relative to one another and which each pass through the respective cylindrical annular space twice, and wherein,
- at the cylindrical annular space, a ratio of an inner diameter (d) to an outer diameter (D) is defined by d{square root over (2)}≧D, and wherein, a number (z) of teeth and gaps and a width (t) of the teeth and of the gaps is defined by t={square root over (2(D/2z))}.
A connecting assembly comprising:
- a first component having an end toothing and a second component having an end toothing, wherein the end toothings each comprise teeth and gaps which are axially inserted into one another and circumferentially engage one another in a clearance-free way and wherein the teeth of the respective end toothings on an outer circumference each comprise outwardly opening circumferential grooves which are delimited by two flanks and which, when the respective end toothings are inserted into one another, together, form a circumferentially extending annular groove in which there is positioned a securing ring on the outside, and wherein the teeth at the first component and the second component, are each positioned within a cylindrical annular space and the gaps are positioned in pairs within two groups of continuous groove tracks which extend at a right angle relative to one another and which each pass through the respective cylindrical annular space twice, and wherein,
- in an axial view, an image of the teeth and gaps comprises:
- a first axis of symmetry (80) which extends through a central axis of the cylindrical space and intersects two of said teeth (82, 89) positioned opposite one another in pairs;
- and
- a second axis of symmetry (100) which extends perpendicularly relative to the first axis of symmetry (80) through said central axis and which intersects two of said gaps (122, 129) positioned opposite one another in pairs.
