Problems solved by technology

As a result, although an inexpensive and particularly compact construction of the turbo coupling is possible, the connected machines must be designed in such a way that their bearings can also absorb the movements acting on the drive and output shafts of the turbo coupling force

Embodiment Construction

[0035] exist figure 1 shows a fluid coupling which is designed as a double coupling with two working chambers 3 . Each working chamber 3 is formed by a pump wheel 1 and a turbine wheel 2 respectively, wherein, in the embodiment shown, the hydrodynamic coupling is provided with a so-called outer wheel drive, that is to say, the two pump wheels 1 are connected via the pump wheel housing 4 are connected to each other and enclose between them two turbines 2 positioned on the output shaft 5 in a back-to-back arrangement. The impeller housing 4 surrounds the two turbine wheels 2 in the circumferential direction.

[0036] The drive of the two pump wheels 1 is effected via the drive shaft 6 carrying the two pump wheels 1 accordingly, wherein an opposing support of the pump wheels 1 facing the output shaft 5 can also be provided on the output shaft 5 or on the turbine wheel 2 department.

[0037] The two impellers 1 and turbine 2 are enclosed together with an impeller housing 4 by a...

Abstract

A hydrodynamic coupling with a bladed impeller (1) and a bladed turbine (2), which form together a torus-shaped working chamber (3) which is filled with a working medium or filled to form a hydrodynamic circulating flow, wherein the pump (1) is supported by a revolving about an axis of rotation drive shaft (6) and the turbine wheel (2) is supported by a revolving about an axis of rotation output shaft (5) and the hydrodynamic coupling a station res Housing for use ( 7), which surrounds the pump wheel (1) and the turbine wheel (2); characterized in that the drive shaft (6) and / or the output shaft (5) in each case by at least one grease-lubricated bearing (13, 14, 15, 16) is mounted with grease nipples (28).

Description

technical field [0001] The invention relates to a fluid coupling. Background technique [0002] Fluid couplings of this type are already known. As can be achieved for the fluid couplings according to the invention, they are used, for example, in heavy machines like pulverizers, crushers, chain conveyors, mills, belt conveyors, especially in open air Used in mining or underground mining for wear-free and vibration-damped starting and running of working machines. In combination with the electronic start adjustment, start times of up to several minutes can be achieved. Here, the belt tension during start-up of the belt conveyor can be reduced to a minimum. [0003] Traditionally, such fluid couplings are usually implemented as externally supported (fremdgelagert) couplings, that is to say their drive shaft and output shaft are supported on the connected machine, i.e. on the drive shaft side On the driving machine and the working machine on the output shaft side or on the tr...
