Definitions
- the invention relates to a hydrodynamic machine, in particular a retarder. However, it also relates to other hydrodynamic machines which are used to transmit torque using a hydrodynamic medium, for example using an oil or using water. Hydrodynamic couplings and converters can be considered as further machines.
- the development of such machines is primarily about increasing efficiency. It is also endeavored to design such a machine in such a way that it can be operated in a desired manner in various operating states.
- the main aim of the retarder is to achieve the highest possible power density. The aim is to ideally design the parts involved in the energy exchange, especially the rotor and the stator.
- the invention has for its object to design a hydrodynamic machine such that the efficiency is further improved.
- the inventors recognized a feature that is essential for efficiency. This characteristic affects the shape of the individual Bucket edge. It is known to chamfer or sharpen the blade edges. However, it is surprising that a significant improvement can be achieved by a relatively simple measure. If the blade edges are chamfered in the manner according to the invention, impact losses are minimized and the efficiency is significantly increased. According to the invention, the bevel in the flowed-on blade areas is chamfered on both sides of the blade tip, and thus not only on one side, as has been the case since then.
- Part of the blade length flows out.
- the areas of the blade edge which are exposed to flow are beveled on both sides of the theoretical center of the blade.
- Figure 1 shows a retarder in a schematic representation in a
- Figure 2 shows a perspective view of a rotor blade wheel.
- Figure 3 shows an even more schematic representation similar to Figure
- FIG. 4 shows a section from a cylindrical section A - A through the object from FIG. 3.
- FIG. 5 shows a section of a cylindrical section BB through the object from FIG. 3.
- the retarder shown in FIG. 1 has a drive shaft 1, on which a rotor blade wheel 2 is keyed, and also a stator blade wheel 3, which is arranged in a housing 4 in a rotationally fixed manner.
- the working fluid is supplied to the retarder through an inlet channel 5 via an unillustrated one
- Control device supplied. It first arrives in a distribution space 6. It is discharged again from an outlet duct 7. Filling slots 8 are located on the rotor blade wheel in the radially inner region, and emptying slots 9 are located in the radially outer region, but these are of no significance for the invention. Between the rotor and the stator
- Paddle wheel is a toroidal work space 10, which is filled and emptied via the filling and emptying slots 8 and 9.
- the rotor blade wheel 2 shown in FIG. 2 reveals a large number of blades 2.1.
- Each blade 2.1 has a blade edge 2.2.1, one of which is designated in more detail.
- the retarder has a profile diameter DP, a so-called center diameter DM and an inner diameter DI.
- Figures 4 and 5 illustrate the two cylinder sections A - A and B - B.
- rotor blades 2.1 are shown on the left and stator blades 3.1 on the right.
- the edges of the blades each have a tip. They are chamfered in different ways.
- the tip is produced in the classic manner by chamfering.
- the rotor blade 2.1 has a thickness s1.
- the bucket is limited by lateral surfaces 2.3, 2.4.
- the tip 2.6 lies in the plane of the lateral boundary surface 2.3.
- the situation is different for the stator blade 3.1 according to FIG. 4.
- the stator blade 3.1 has a thickness s2.
- the tip 3.6 is in the theoretical blade center plane 3.5. There are therefore two bevels.
- the cylindrical section A - A is placed in a diameter range of the retarder, in which working medium flows out from the edge of the rotor blade 2.1, but flows against the edge of the stator blade 3.1.
- FIG. 4 An area is shown in the stator vane 3.1 from which working medium flows, and an area in the rotor vane 2.1 to which the working medium flows. Accordingly, the tip 3.6 of the stator blade 3.1 is offset from the longitudinal center plane 3.5 of the blade. It lies in the plane of the lateral boundary surface 3.4. The blades are arranged in a "pike" manner. The tips are thus facing each other. In this illustration, the blades of the rotor and stator are essentially aligned with one another.
- the arrangement according to the invention leads to a minimization of the impact losses and thus to a significant increase in efficiency and smoothness.
