Connection Arrangement

Abstract

Connection arrangement between a shaft and a bore, wherein the connection can be produced via a pressing operation and a subsequent soldering operation. An object on which the invention is based is to improve a connection arrangement in such a manner that sufficient wetting of the components with solder is provided even in unfavorable circumstances in terms of fit and that, before the soldering operation, the connection between the pressed-in shaft and bore has at least one gap. The circumferential length of the at least one gap and/or the sum of all the circumferential lengths of the gaps is less than the circumferential length of the bore. The resulting gaps have a gap width between 0.05 and 0.2 mm, preferably 0.1 mm. With these gap widths, it is possible to achieve a particularly good flow of solder during soldering.

Claims

1-5. (canceled)

6. A connection arrangement comprising: a member defining a bore; a shaft configured to be pressed into said bore; the connection arrangement being between said shaft and said bore, wherein a connection can be made between said shaft and said bore via a pressing operation and a subsequent soldering operation; said shaft being configured to be pressed into said bore via said pressing operation; said bore defining a bore circumferential length; wherein, before the soldering operation, the connection between said shaft pressed into said bore and said bore defines at least one gap; said at least one gap having a gap circumferential length; and, wherein at least one of said gap circumferential length and a sum of all gap circumferential lengths of said at least one gap is less than said bore circumferential length.

7. The connection arrangement of claim 6, wherein said at least one gap is formed by at least one circular arc-shaped relief.

8. The connection arrangement of claim 7, wherein said at least one gap has a maximum gap width between 0.05 millimeters and 0.2 millimeters.

9. The connection arrangement of claim 7, wherein said at least one gap has a maximum gap width between 0.07 millimeters and 0.15 millimeters.

10. The connection arrangement of claim 7, wherein said at least one gap has a maximum gap width of 0.1 millimeters.

11. The connection arrangement of claim 6, wherein said member is a holder.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0015] The invention will now be described with reference to the single figure of the drawing (FIG. 1) which shows a bore of a connection arrangement between a shaft and the bore.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

[0016] FIG. 1 shows a bore 1 of a connection arrangement (not represented any more specifically) between a shaft (not represented either) and the bore 1. The bore 1 has a main radius 2 which corresponds to the diameter of the shaft (not represented) in the form of a press fit. Four reliefs 3 are arranged in a uniformly distributed manner over the circumference of the bore 1. The reliefs 3 each have a secondary radius 4, and therefore the reliefs 3 are configured to be circular arc-shaped.

[0017] The reliefs 3 are arranged in such a way that in each case a gap 6 delimited by the radii 2 and 4 and having a maximum gap width 7 is formed between an imaginary circle line 5 of the bore 1 in the region of the reliefs 3 and the reliefs 3.

[0018] The maximum gap widths 7 and the size of the circular arcs of the reliefs 3 can be individually adapted through the choice of suitable secondary radii 4 and associated imaginary center points 8 of the reliefs 3.

[0019] It is understood that the foregoing description is that of the preferred embodiments of the invention and that various changes and modifications may be made thereto without departing from the spirit and scope of the invention as defined in the appended claims.
