Embodiment Construction

[0045] figure 1 shows the principle of the connection system according to the invention for axially securing the shaft-sleeve connection in the assembled state, while figure 2 An enlarged view showing a detail of the connection system. Said connection system comprises a shaft 1 and a bushing 5, said shaft having on one end thereof a journal 2 with external splines 3 and provided with a groove 4 at a short axial distance from the journal, In the present exemplary embodiment, the bushing is designed as the inner ring of the joint. The bushing 5 has a widened outer groove 6 on its outer circumference and a notch 7 on its end face facing the shaft 1, said notch 7 having a larger diameter than the inner diameter of the bushing so that behind its end face The axial stop surface 8 is formed at the shorter axial distance. The inner diameter of the bushing 5 axially adjoining the recess 7 corresponds to the outer diameter of the shaft 1, where the two diameters form a fit with each...

Abstract

The invention relates to a connection system for axially securing a shaft-sleeve connection, comprising a shaft (1) and a sleeve (5) with an inner stop surface (8) for the shaft (1) ) and an outer groove (6) for axial positioning of the fixing mechanism, wherein the fixing mechanism has an axially extending sleeve-like portion and a radial flange, the sleeve-like portion at least partially surrounds the sleeve (5) , while the radial flange acts at least partially on the annular end face of the bushing (5) from behind. According to the invention, the inner stop surface (8) for the shaft (1) is formed in the bushing (5) by a recess (7). The fastening means is formed by a radially deformable holding sleeve (14), whose axially extending sleeve-shaped part (15) is surrounded by a tensioning band (19). In the assembled state of the shaft-sleeve connection, the radially inwardly offset region (18) of the retaining sleeve (14) coaxially surrounds the widened outer groove (6) of the sleeve (5) and can be stretched The tightening band (19) is locked in the widened outer groove (6) of the shaft sleeve (5), and the radial flange (16) of the holding sleeve (14) is fixed against the axial direction of the shaft (1) in the locked state. on the ring (13).

Description

technical field [0001] The invention relates to a connection system for axially securing a shaft-sleeve connection and a method for axially securing a shaft-socket connection. Background technique [0002] In connection systems of shafts and bushings that are not exclusively force-locked, a form-locking axial fastening is provided in principle, which determines the relative position of shaft and bushing in such a way that , the axial securing structure engages the two components in a form-fitting manner and prevents the connection from loosening in the event of an axial force acting on the shaft and / or the bushing. For this purpose, a variety of systems are known which ensure different levels of security which are technically required in the respective application, during production and during user operations, ie during assembly and disassembly of the shaft-sleeve connection. Different workloads, and these systems contribute in different ways to reduce the weight of the con...
