Claims13
Method for creating a press connection arrangement of two components having an axis of rotation, wherein the axis of rotation extends in an axial direction (A) of the press connection arrangement, and having a radial direction (R) which is orthogonal to the axial direction (A) and a circumferential direction (U) extending in a plane spanned by the orthogonal and the radial direction (R), wherein the press connection arrangement is carried out by creating a non-positive connection by means of a microform connection between a radially inner component with a radially outer contact surface and a radially outer component with a radially inner contact surface, the method comprising the steps of:
- providing the inner component with an axially extended and radially outer contact surface which is rotationally symmetrical to an axis of rotation of the inner component;
- providing the outer component with an axially extended and radially inner contact surface which is rotationally symmetrical to an axis of rotation of the outer component;
- laser structuring at least one of the contact surfaces, wherein a structuring is created having a surface profile that is point-symmetrical with respect to the respective axis of rotation;
- non-contact arranging of the inner component and outer component with respect to one another in the intended axial relative position;
- joining the press connection arrangement, wherein a pressure-stress contacting of the contact surfaces to each other is carried out by a purely radial joining movement, so that the contact surfaces are pressed purely in the radial direction (R) during joining, wherein in the joined state the axis of rotation of the inner component and the axis of rotation of the outer component coincide with the axis of rotation of the press connection arrangement.

Method for creating a clamping connection which has an axial direction (A) along which an axis of rotation of the clamping connection extends and which has a radial direction orthogonal thereto, having a receptacle which has a radially inwardly oriented conical contact surface, which corresponds to the outer surface of a truncated cone, and having a shank section, in particular a tool shank, which has a radially outward-oriented conical contact surface which also corresponds to the outer surface of a truncated cone and is formed complementary to the contact surface of the receptacle, the method comprising the steps of:
- providing the receptacle with a radially inwardly oriented, conical contact surface,
- providing the shank section with a radially outwardly oriented, conical contact surface,
- laser structuring of at least the contact surface of the receptacle, wherein the structuring is created having a surface profile which is point-symmetrical, in particular, rotationally symmetrical, to the axis of rotation of the receptacle, wherein the laser structuring comprises, in particular, line-like elevations extending in a plane spanned by the axial direction (A) and the radial direction (R),
- non-contact arranging of the receptacle and shank section with respect to one another in the intended axial relative position,
- joining the clamping connection, wherein a pressure-stress contacting of the contact surfaces to each other is carried out by a purely axial joining movement, so that the contact surfaces are pressed purely in the axial direction (A) during joining, wherein, in the joined state, the axis of rotation (52) of the shank section and the axis of rotation of the receptacle lie on one another with the axis of rotation of the clamping connection.
Clamping connection which has an axial direction (A) and which has a radial direction (R) orthogonal thereto, having a receptacle which has a radially inwardly oriented contact surface, which corresponds to the outer surface of a truncated cone, and having a shank section, in particular a tool shank, which has a radially outward-oriented contact surface which also corresponds to the outer surface of a truncated cone and is formed complementary to the contact surface of the receptacle, wherein the shank section is clamped against the receptacle by axially directed clamping, characterized in that the radially inwardly directed contact surface of the receptacle is laser-structured, the laser structuring having a surface profile that is rotationally symmetrical with respect to the axis of rotation and includes line-like elevations, each extending in a plane spanned through the axial direction (A) and the radial direction (R).
(canceled)
A method for using a press connection of two components having an axis of rotation, wherein the axis of rotation extends in an axial direction (A) of the press connection arrangement, and having a radial direction (R) which is orthogonal to the axial direction (A) and a circumferential direction (U) extending in a plane spanned by the orthogonal and the radial direction (R), wherein the press connection arrangement is carried out by creating a non-positive connection by means of a microform connection between a radially inner component with a radially outer contact surface and a radially outer component with a radially inner contact surface, the method comprising the steps of:
- a. prior to using the press connection, using a laser to create a structure having a surface profile that is point-symmetrical with respect to the respective axis of rotation and the structure comprises one of:
- i. lines extending at an angle between 60° and 120° to the resulting direction of force, and
- ii. intersecting lines resulting in an engagement surface and extending at an angle between 60° and 120° to the resulting direction of force;
- and
- b. transmitting axial forces and a torque, wherein the axial forces and the torque define a resulting direction of force.
