Abstract

A high-pressure toothed gear according to the invention is a gear designed in such a way that it makes it possible to transform the force of a fluid in a high-pressure system into mechanical, preferably circular motion, or vice versa, that it acts as a high-pressure pump where mechanical force is being supplied. The invention consists in (two or more) toothed, when engaged rotating elements, whereby the teeth of the elements are shaped so that fluid can flow between the teeth in one or the other direction depending on the position of momentary sealing points which are created between momentarily engaged teeth. The essential feature of the invention is that the toothing of the rotating elements, e.g. wheels, is designed in such a way that two or more rotating elements rotate in engagement, whereby the very shape of the body of individual teeth makes it possible to create momemtary sealing points, while the shape and the execution of the teeth allow fluid to flow in the moment of mutual engagement of individual teeth. Such a structure makes it possible for the fluid to flow while the teeth slide in engagement, which prevents the production of pressure or subpressure.

HIGH PRESSURE GEAR MECHANISM

The subject of the invention is a high-pressure gear mechanism that can be used as a driving mechanism, e.g. vessels or. as a high-pressure pump. The mechanism according to the invention enables the transfer of fluid (fluid, gas) force directly into the rotation of the drive axle or other drive mechanism in a system of high-pressure or low-pressure lines. The invention belongs to class F 15 B 15/00 of the international patent classification.

-2The technical problem that the present invention successfully solves is the construction and implementation of such a mechanism that will allow the direct transfer of fluid force in the high-pressure system into mechanical movement, the pre-annular circular, or vice versa, will act in the supply of mechanical force as a high-pressure pump. The mechanism of the invention should be suitable for widespread use.

Known solutions to the problem posed are mechanisms that convert fluid pressure primarily to linear mechanical motion. These are different versions of high-pressure valves, etc., but they do not solve the technical problem. The classic solution in the grip of the gear wheels, however, is also not useful for our purpose, since there must be a certain clearance between the teeth of one gear and the teeth of the other gear wheel; under pressure on one or the other side of the gear pair. Therefore, the utilization of such a gear assembly in its use for the purpose of solving a technical problem of the invention would be small.

The high-pressure gear mechanism according to the invention enables the solution of the set technical problem with gear, rotating elements (two or more), whereby the teeth of the elements are machined so that fluid between the teeth can flow in one or another direction depending on the position of the current sealing points , which are created by gritted teeth in an instant grip.

I will explain the invention in more detail on the basis of an embodiment and accompanying drawings, of which:

Figure 3 a, b, c, d, e are examples of dental flap machining.

Fig. 4 is a side view of a high-pressure gear mechanism according to variant III in cross-sectional view;

The high-pressure gear mechanism according to the invention is shown in FIG. 1 in a cross-sectional side view I. A partial cross-section of the pinion is also shown. The point of the solution is that on rotary elements, e.g. the wheels are grooved so as to rotate two or more rotating elements in the grip, with the shape of the individual tooth body creating instant sealing points, and the shape and design of the gear attachments allowing fluid to flow at the moment of mutual grip of the individual gear attachments. This design allows fluid to flow when the gears in the grip slide, which prevents pressure or pressure buildup. underpressure.

The number of gears depends on the diameter of the rotary element. Between the contact points, the rotary members are sealed apart, which means that they have at least one permanent and one or more current sealing points with each other. When rotating, the current sealing points pass into each other. The number of current sealing points depends on the number of gear attachments currently in the grip. Fluid flows left or right between each rotary element between the gears

-4Settings by channels or. parts that are not currently in grip, depending on the shape of the gears.

In the housing 1, two rotational elements 2,3 are rotated in contact, having alternately gear teeth 2a, 3a arranged along their periphery, respectively, with grooves 2b, 3b corresponding to the dimension and shape of the gears 2a, 3a. When rotating the rotating elements 2,3, instantaneous sealing points are created in the grip of the pinions 2a, 3a and grooves 2b, 3b. Thus, in the drawn position in Figure 1, the current sealing point at contact point A between the two rotating elements is 2.3. When rotating the two rotating elements 2,3, the sprocket 2a or. 3a into gear groove 2b or. 3b and due to the specific shape of the gears (eg such as shown in Figure 3a), the sealing point moves. As a result, there is always at least one current sealing point between the fluid inlet and outlet chamber.

Due to the shape and construction of the gears, which can be implemented in several ways and shown in Figure Sa.b.c.d.e, the fluid pressure in both chambers is the same.

Figure 2 shows the high-pressure gear mechanism after variant II in lateral cross-sectional view. Due to the larger number of gears on the rotating elements and the shape of the gears as shown in Figure 3c, the sealing points are created between the individual gears. In the situation shown in Fig. 2, one permanent seal point A is created between the pinions, while the current seal points change. The shapes of the toothed nozzles prevent the formation of underpressure or overpressure in the individual chamber.

-5Fig. 4 is a cross-sectional view of a high-pressure gear mechanism according to variant III in cross-sectional view. In this case, the gears are machined e.g. just as shown in Fig. 4c, which allows the creation of an intermediate space between the individual gears in the grip of both rotary members.
