Definitions
- the invention relates to a hydrodynamic coupling with a pump wheel and a turbine wheel, which together form a toroidal working space.
- the work area is used to accommodate one
- Working medium such as oil or water, which transmits a torque.
- Hydrodynamic couplings are used to transmit torque from a drive motor to a work machine, for example from an electric motor to a grinding machine, or to a conveyor system. Due to the working characteristics of such a clutch, this will be the case
- Torque transmitted from the engine to the machine in a very elastic way In particular when starting off, that is to say with the motor rotating and the machine at a standstill, the curve of the torque transmitted to the machine increases only slowly. If the drive motor is an electric motor, it is ramped up to its nominal speed without load.
- Flow-controlled hydrodynamic couplings are used particularly heavily in mining.
- they are connected between an electric motor and a conveyor belt.
- An important application is the so-called chain scraper conveyor.
- the Coupling for gentle torque transmission not only in the start-up phase, but also when the scraper conveyor is running, namely when the scraper conveyor encounters particularly hard material during its work.
- the invention is based on the object of designing a drive device with a motor and a flow-controlled hydrodynamic coupling in such a way that sufficient torque is transmitted from the motor to the working machine during start-up operation even when the load on the working machine is very high.
- Inlet for the working medium in the working area is moved radially outwards, the greater is the rotational pressure of the inflowing working medium.
- This greater rotational pressure can overcome the hydrodynamic pressure in the work area. In this way, a full filling of the working space can be achieved, and thus a transmission of a sufficiently large torque from the drive motor to the working machine, for example to the chain scraper conveyor mentioned.
- the inlet does not necessarily have to be on the largest radius, that is, at the apex of the work area. However, it should be in the area of the apex of the work area.
- a chain scraper conveyor can also be started up from a standing position without any problem if extremely large amounts of coal have fallen into its feed area.
- Figure 1 shows a flow-controlled hydrodynamic coupling according to the invention in an axial section.
- Figure 2 shows a flow-controlled, hydrodynamic coupling according to the prior art, again in an axial section.
- the coupling shown in Figure 1 is designed in a duplex design.
- the clutch has an input shaft 1 and an output shaft 2.
- the drive shaft 1 is non-rotatably connected to a first pump wheel 3.1, and further - via a cylindrical wall 6, to a second pump wheel 3.2.
- the second pump wheel 3.2 is rotatably connected to the cylindrical wall 6.
- the output shaft 2 carries a first turbine wheel 4.1 and a second turbine wheel 4.2.
- the wheel pairs 3.1, 4.1 and 3.2, 4.2 each form a working space 5.1, 5.2 with one another.
- the rotating components mentioned are surrounded by a housing 7.
- the housing has a housing inlet 7.1 and a housing outlet 7.2 for a working medium.
- This can be water or oil, for example.
- the so-called coupling shell 7 is non-rotatably connected to the pump wheel 3.2. Together with the pump wheel 3.2, this forms one
- a bore 3.2.1 is decisive according to the invention. This creates a conductive connection between flow channel 9 and working space 5.2.
- the bore 3.2.1 can run parallel to the axis or inclined to the machine axis. It can also be configured downstream in the manner of a nozzle.
- An outlet valve 3.1.1 is assigned to the pump wheel 3.1.
- the working medium is supplied to the clutch from an external circuit, not shown here.
- the circuit comprises a cooler, a regulator and other known units in a known manner.
- the working medium is introduced into the housing through the housing inlet 7.1. It then flows radially inward within the housing up to approximately the output shaft 2. From there it enters the flow channel 9, passes through the transverse bore 3.2.1 into the working space 5.2, from there into the working space 5.1, and from there via valve 3.1.1 to the housing outlet 7.2.
- the embodiment of a known hydrodynamic flow coupling shown in FIG. 2 is again a duplex coupling.
- the decisive difference compared to the coupling according to the invention is that the inlet 3.2.1 in the working space 5.2 is on a much smaller radius. A complete filling of the work rooms 5.2, 5.1 with a slip of 100
