CS209157B1 - Coupling of bellows coupling with shaft - Google Patents

Abstract

The subject of the invention is the connection of the bellows of the coupling with the shaft and its purpose is to solve the non-power transmission, for example from the control device to the control device. The stated purpose is achieved by inserting a flexible insert, which is slid onto the shaft, into the bellows flange. A protective strip is fixed on the outer surface of the bellows flange, on which a tightening clip is mounted.

Description

(54) Coupling bellows to shaft connection

Annotation

It is an object of the present invention to provide a coupling of the bellows of the clutch to the shaft and is intended to solve non-force transmission, for example from a control device to a control device. This is accomplished by inserting a flexible insert which is slid on the shaft into the bellows flange. A protective band is attached to the outer surface of the bellows flange, on which a clamping clip is fitted.

WHAT

BACKGROUND OF THE INVENTION The present invention relates to a coupling of a bellows to a shaft and to a non-force transmission of rotational motion, for example from a controlled device to a control device.

It is known to connect the bellows of the clutch to the shaft for the power transmission of relatively large torques and revolutions. For this power transmission, a thick-walled steel bellows is used, whose connection with the shafts requires hubs, which are connected with the bellows itself by means of screws, gearing and the like. The hubs are then attached to the shafts by feathers, wedges, as well as by grooving, pressing and the like.

It is also known to connect a thin-walled single- or multi-shell bellows to a non-force coupling! rotating motion. The connection is formed by hubs which are connected to the bellows of the coupling by soldering or gluing. The hubs are also attached to the shafts by tongues, crimping, locking pins and the like.

The disadvantage is the relatively high joint weight ' ^! and the mass moment of inertia. The disadvantage is also the relatively high labor intensity, difficult and laborious assembly and disassembly.

The above-mentioned drawbacks are eliminated by the embodiment of the coupling of the bellows-clutch to the shaft according to the invention, which is based on the fact that it consists of a flexible insert which is inserted into the flange of the bellows and slid on the shaft. On the outer surface of the bellows flange is

Claims (1)

! t »TAKE YOU Coupling bellows-shaft connection, characterized in that it consists of a flexible insert (2) which is inserted! in the bellows flange (1) and slid onto the shaft (5), a protective band is fastened, on which the pulling clip is fitted. _% The advantage of the joint according to the invention is that the weight, the mass moment of inertia and the manufacturing effort of the joint are reduced. It also has the advantage of a relatively high operational reliability of the joint (fast and easy assembly and disassembly of the joint The accompanying drawing shows an exemplary embodiment of a joint including a bellows and a connector according to the invention in front view. The connection according to the invention consists of a cylindrical flexible insert 2 which is inserted into the flange of the bellows 1 and which is slid on the shaft 5. A protective band 4 is fastened to the outer periphery of the flange of the bellows 1, on which the tightening clip 3 is fitted _. When assembling the connection according to the invention, it is first necessary! the elastic insert 2 is inserted into the flange bore 1 of the bellows 1 and then the shaft 5 is inserted into the bore of the liner 2. bellows flange 1 joint. At the same time, the protective band 4 protects the flange of the bellows 1 from mechanical damage when tightening the clamp 3. BACKGROUND OF THE INVENTION 1 '' i '♦ wherein a protective band (4) is attached to the outer surface of the bellows flange (1) on which the clamp (3) is fitted.
