Method for producing a compression connection

Abstract

A method for producing a compression connection for a driving part (1), in particular for an essentially ring-shaped driving part (1) on a shaft (3), in particular in the case of a built-up camshaft with which the driving part (1) has an opening that essentially corresponds to the outside diameter of the shaft (3),the driving part (1) sits on the shaft with coverage in the finished compression connection,an adhesive layer is applied between the circumferential surfaces of the driving part (1) and the shaft (3), is to be improved.

Description

The figures show schematically:

FIG. 1 a schematic diagram of a driving part,

FIG. 2 multiple driving parts mounted on a shaft by the method according to the invention.

FIG. 1 shows a driving part 1, in particular a cam, having an essentially ring-shaped design equipped with a bulge 2. In addition, the driving part 1 has an opening 4 whose diameter corresponds essentially to the outside diameter of the shaft 3 shown in FIG. 2. To allow the driving part 1 to be arranged on the shaft 3 in a fixed manner, it is heated to create a compression connection by the inventive method until reaching a joining temperature, so that the diameter d of the opening 4 is increased. The widening of the diameter d of the opening 4 may be only large enough to allow the driving part 1 in the heated state to be pushed onto the shaft 3 directly without exerting any axial or radial forces and it solidifies on reaching a predetermined position and then is joined fixedly to the shaft 3. The application of the driving part 1 is thus limited according to this invention to the extent that the adhesive applied to the connection of the driving part 1 and/or the shaft 3 is not removed at all or not to any considerable extent in the joining operation.

Claims

1. A method for producing a compression connection for a driving part (1), in particular for an essentially ring-shaped driving part (1) on a shaft (3), in particular in the case of a built-on camshaft, wherein the driving part (1) has an opening corresponding essentially to the outside diameter of the shaft (3),the driving part (1) sits on the shaft with coverage in the finished compression connection,an adhesive layer is provided between the circumferential surfaces of the driving part (1) and the shaft (3), whereinthe driving part (1) is heated until reaching the joining temperature and is thereby widened, andthe driving part (1) is pushed onto the shaft in an essentially force-free operation.

2. The method according to claim 1, wherein the shaft (3) is joined without after-working.
