Problems solved by technology

However, it has been found that when the ring is pushed onto the conical expanding mandrel, the axial movement required here results in relatively high frictional forces between the ring and the expanding mandrel, which can lead to wear of the ring. and thus lead to damage to the ring

Embodiment Construction

[0038] according to Figure 1 to Figure 5 , a mounting device 1 comprising an expansion tool 4 and a mounting tool 5 , by means of which a split ring 2 can be mounted on a shaft 3 . The expansion tool 4 comprises a expansion mandrel 6 , a pressure pin 7 and a stripping sleeve 8 , which is also referred to as the expansion tool stripping sleeve 8 in the following. The installation tool 5 instead comprises an installation sleeve 9 , a cavity 10 and a stripping sleeve 11 , which is also referred to below as the installation tool stripping sleeve 11 .

[0039] according to Figure 1 to Figure 3 , the expansion mandrel 6 has a plurality of expansion fingers 12 arranged in a distributed manner in the circumferential direction, and the expansion fingers can be spring-elastically adjusted in the radial direction by means of the pressure pin 7 . In this case, the expansion fingers 12 are formed in one piece, in particular with the holder 13 of the expansion mandrel 6 . The pressure ...

Abstract

The invention relates to a method for assembling an open ring (2) on a shaft (3). The ring (2) is positioned on a spreading tool (4) in a coaxial manner in a relaxed state such that a spreading mandrel (6) of the spreading tool (4) engages axially into the ring (2), and the spreading mandrel (6) is spread radially until the ring (2) is widened to a specified spread cross-section in order to tension the ring (2). In the tensioned state, the ring (2) is axially pressed onto a setting sleeve (9) of a setting tool (5) by means of a scraper (8) of the spreading tool (4), and the ring (2) is pressed axially onto the shaft (3) in the tensioned state by means of a scraper (11) of the setting tool (5).

Description

technical field [0001] The invention relates to a method for fitting a split ring on a shaft. Furthermore, the invention also relates to an assembly device for carrying out such a method as well as an expansion tool and an installation tool. Background technique [0002] An open ring (that is to say a ring that is not closed in the circumferential direction but has exactly one opening) can be mounted on the shaft in order to be used there as a seal and / or as an axial stop or an axial lock pieces. For this purpose, the corresponding ring is usually inserted into a closed circumferential annular groove formed on the shaft. In order to be able to insert the ring into the annular groove, the ring needs to be expanded (that is to say tensioned) so that it can be pushed over the outer cross-section of the shaft into the annular groove. Depending on the material that can be used for the rings, the respective rings have only reduced bending elasticity, so that the expansion of th...
