DE102007008274A1 - Hose coupler for rotary components, has clamp attached radially outwards on hose over retaining ribs, so that hose is clamped between ribs, where clamp is pressable by radial multi-crimp on hose - Google Patents

Abstract

The coupler (1) has a clamp (2) that is radially deformable around a longitudinal axis (1'), where edges (3) of the clamp lie closer with the longitudinal axis. An end section (7) of a hose (8) is attached to an end section (6) of a tube (5) and is fixed by the clamp, where the end section of the tube is provided with rotating retaining ribs. The clamp is attached radially outwards on the hose over the retaining ribs, so that the hose is clamped between the ribs. The clamp is pressable by a radial multi-crimp on the hose and is made of metal.

Description

The The invention relates to a hose coupling with the features of the Preamble of claim 1.

It starts from the German publication DE 103 59 799 A1 out. In this a hose coupling is described with a about a longitudinal axis radially deformable clamp. The edges of the clamp are in this case closer to the longitudinal axis of the hose coupling than the intermediate region. The hose coupling is provided for a pipe, on the end portion of an end portion of a hose can be plugged and clamped by means of the clamp. The end portion of the tube has a circumferential retaining rib, over which the end portion of the tube can be pushed away. Radially outward around the hose, in the area of the retaining rib, the clamp can be applied so that the hose is clamped between the retaining rib and the clamp. To clamp the hose, the hose coupling further comprises a screw connection, wherein when tightening the screw the radius of the clamp is reduced and thus the hose is clamped tightly on the pipe.

Becomes a generic hose coupling for rotating components used, arises due to the one-sided Screw connection an imbalance, resulting in the operation of the rotating Makes components negatively noticeable.

task The present invention is a hose coupling without unbalance show.

These The object is achieved by the feature dissolved in the characterizing part of claim 1.

The Advantages over the prior art arise when the arc-shaped clamp shape as a multi-crimp ring (without screw connection, or turnbuckle) executed becomes. A compression between the hose and tube takes place, as in the cylindrical Multi-crimp ring, by means of a shrinking device. It will the clamp by means of radially pressing jaws in diameter remaining reduced (shrinkage of the Schellendurchmessers). Next is the Hose coupling according to the invention a cost Connection with screw clamps. Continue to emerge Package advantages due to the elimination of the turnbuckle, resulting in a lower height leads. Furthermore formed in an advantageous manner a constant contact pressure the clamp and this over the entire width due to a low relaxation behavior, from.

The Versions according to the patent claims 2 and 3 are two particularly preferred embodiments.

By The embodiment according to claim 4 Damage to the hose prevented.

in the The following is the invention with reference to a particularly preferred embodiment explained in two figures.

1 shows a section through a hose coupling according to the invention 1 along a longitudinal axis 1' ,

2 shows a clamp according to the invention in three-dimensional view.

In both figures are the same for the same components Reference numerals.

1 shows a section through a hose coupling according to the invention 1 along a longitudinal axis 1' , Radial of the longitudinal axis 1' extends an end portion 6 a pipe 5 , Radially outward around the end section 6 extends an end portion 7 a hose 8th , In the overlap area of pipe 5 and hose 8th indicates the end portion of the tube 6 a radially circumferential retaining rib 9 on. In the area of this retaining rib 9 is radially outward around the end portion of the hose 7 a clamp 2 arranged. In the axial direction of the longitudinal axis 1' are here edges 2 the clamp 2 closer to the longitudinal axis 1' as an intermediate area 4 ,

According to the invention is the clamp 2 by radial Multicrimpen on the hose 8th pressed. The clamp is preferred 2 crimped radially at at least six locations. To create a particularly good and lasting crimp connection, the clamp is 2 preferably of a metal, for example of a ferrous material. Furthermore, the edges are preferred 3 rounded radially inwards to prevent damage to the hose 8th to avoid.

The inventive design results in a cost-effective connection with respect to the known from the prior art screw clamps. Furthermore, a package advantage is created by the elimination of the turnbuckle, which leads to a lower overall height. The Multicrimpen also results in a constant contact pressure under the clamp 2 over the entire clamp width. The rounded clamp edges also prevent damage to the hose 8th , As a big advantage, it can be seen that no unbalance arises with rotating components.
