Abstract
The invention relates to a workpiece made of two components joined together by means of an adhesive. A first component has a reservoir for receiving the adhesive in a first state, and one of the components undergoes a geometric change in a second state during the joining process such that the reservoir is reduced in size and adhesive is moved out of the reservoir.
Claims20
A workpiece comprising two components joined together via an adhesive, wherein a first component of the two components has a reservoir for receiving the adhesive in a first state, and one of the two components undergoes a geometric change in a second state during a joining process such that the reservoir is reduced in size and the adhesive is moved out of the reservoir.
A joining method for joining a first component and a second component, the method comprising:
- in a first step, filling a reservoir of the first component with adhesive, the reservoir formed as a groove on an outer surface of the first component,
- in a second step, pushing the second component onto the first component in a joining direction so that:
- an axial stop of the second component strikes against a partial piece of the first component,
- the first component is nested within the second component, and
- the reservoir is delimited by an inner wall of the second component, and
- in a third step, further pushing the second component onto the first component in the joining direction so that the partial piece breaks off of the first component at a predetermined breaking point, and
- in a fourth step, further pushing the second component onto the first component in the joining direction so that:
- a volume of the reservoir is reduced, and
- the adhesive is pressed out of the reservoir and into a radial gap formed between the inner wall of the second component and an outer wall of the first component, and
- in a fifth step, further pushing the second component further onto the first component in the joining direction until the second component axially abuts with the first component.
A workpiece assembly comprising:
- a first cylindrical component having a reservoir having a first volume is configured for receiving an adhesive,
- a second cylindrical component disposed around the first cylindrical component so as to delimit the reservoir, and
- a third cylindrical component disposed radially between the first cylindrical component and the second cylindrical component, and
- in a first assembly state:
- adhesive is disposed in the reservoir, the reservoir open on a radial outer side,
- the reservoir is axially delimited by the third cylindrical component and radially delimited by the first cylindrical component on a radial inner side, and
- in a second assembly state, the reservoir is radially delimited by the second cylindrical component on a radial outer side, and
- in a third assembly state:
- the adhesive is disposed in a radial gap via axial displacement of the second cylindrical component and the third cylindrical component, the radial gap formed between the first cylindrical component and the second cylindrical component, and
- the reservoir has a second volume less than the first volume.
