Description

Rotary Bucket Machine

The invention relates to a rotary piston machine (motor, pump, compressor, steam engine, hydraulic motor, etc.) t whose rotor τοη planetary gears is guided, which is calibrated a sun gear so abwSleen that the rotor in a or several consecutive and adapted to the rotor Work chambers in and out of a stationary housing can be brought out of them.

The external structure of the machine is basically the same as that of the previously known rotary piston machine ^ Der The main difference, however, is that the rotary drive also ensures a significant increase in the torque on the inner shaft of the hash and a strong reduction in speed

Also the one proposed in the filter patent 1,231,055 Rotary piston engine exhibits the well-known type of Rotary motion ftuT. which, by the way, also at c & r p: find-

according to rotary piston machine is applied. In the rotary piston engine according to the older patent, the rotor is freely rotatable on an eccentric shaft and the movement of the rotor is caused by this eccentric shaft. The planet gears are stored in a freely rotating flange gear carrier and do not contribute to the guidance of the rotary piston. The shaft of this rotary piston engine lttuft against de «rotor» it three times speed, among other things _t resulting in the already relatively high rotor speed for the "Eisten the intended Anwendungegebiete nloht wtin- ■ is ohenswert"

In contrast, the object of the invention is to create a rotary piston machine which has a significantly improved Keohanism of rotor movement and energy transfer Has swisohen rotor and Masohinenwelle.

In the rotary piston machine mentioned at the outset, this object is achieved in that the internal shaft gate ends at the rotor and rotates at its end wears a camp sole, and that one on her eccentric shaft cones in the rotor, on the other hand, on a sentrisohen shaft cone in the Ijagersohelbe the Haeohlnenwelle are stored.

. Another feature of the invention

lies in the fact that the distance between the shaft journal centers and the corresponding Ilanetenred centers for all Ilaneten wheels, which lead the same rotor, is the same. The connecting lines of the shaft journal centers and the associated Ilanetenr-dmenter must run infrequently for ollen llanetenrfidern driving the same rotor.

A preferred embodiment of the invention is characterized in that disks or covers are attached to the sides of the rotor, which rotate with and which Limit and create cross winds of the workers. In In these basins, suitable slots are formed by appropriate Lfinge in order to be able to move the rotors and the lid to open the inlet and outlet knttle and the To bring about the desired control of the flow of work medium (gas, steam, liquid) in the workmen.

dee Sonnenradeβ be, έίηβ sketch of such An "order shows the Pig. 1. In the stationary housing 1 there are three working chambers 2, 3 t 4 _f, each of which can be filled with or less filled by the rotor 5 during its movement. The xlotor gets its special movement through the gear described below. The ttotor 5 is in the plane of the paper. Before that, a strong disk 8 is attached to the linden of the drive shaft 13, for example by forging. On this disk 8, the planet gears 7 are located in corresponding bearings at the same distance from the center of the drive shaft 13. The planetary gears 7 mesh with the aforementioned sun gear 9, which is designed to be stationary because it forms part of the case 1 or is connected to it. On the opposite sides of the bearings of the individual planet gears 7 there is a shaft journal 6 which is manufactured in one piece with the planet gear 7 or is attached to it. All bearing journals 6 have the same eccentricity. The rotor 5 is guided by these shaft journals 6 because they engage in the bearings of the hotor 5.

When the drive shaft 13 is rotated clockwise with the hub 8, the lower half of the Hotor slides, those in the wing. 1 with the BoBugseeihen A 1st, first in the working chamber 3 "to cause a reduction in volume there. After further turning the drive shaft .13, the motor half B slides into the working chamber » and causes a decrease in volume there, wonacL 11?

The rotor half A engages in the working chamber 4 and causes a reduction in volume there. As soon as this position is reached, the rotor halves A and B have swapped their positions, ie the rotor 5 (and the drive shaft) have made half a turn (180 °). After a further half turn of the ./eil, the rotor 5 again passes through the work kasaiern in the order 3, 2, 4, whereupon the output position shown in FIG. 1 is reached during one turn of the ', / hurry (and the rotor), the rotor 5 moves into each of the three working chambers 2, 3 »4 twice in and out. If the invention is therefore used for a four-stroke cylinder, three working strokes result for one revolution of the shaft, corresponding to a cylinder piston machine of the same type. When using a two-stroke machine (or for example as a rump ©), 3ich result in six strokes for each revolution of the ./eile. · Υ _θ ηη it should be useful in special cases, such as B. with high output power, a plurality of rotary pistons can easily be combined on the same machine shaft.

Between any two of the work clerks 2, 3 »4» is sioh between the rotor 5 and the stationary Oehäuee 1 a seal 11, which constantly comes into contact with the two mentioned components. This is without further ado possible since the one in Pig. 1 shown Kpitrocholden- : lotor there are three stationary points, which always remain on the circumference of the dotor when he is

runs. Through these points can therefore vortical to the On the paper plane three lines can be drawn, which nan can address as the generator of the rotor. In Fig. 1 these three lines agree with the contact lines between the rotor 5 and the spring loaded seals 11 overeln * -

The housing having a corresponding slot 22 * äs sufficient here to consider the upper working chamber. When the rotor 5 moves from the position shown in FIG. 3 to the position shown in FIG. 4, the volume of the upper chamber 4 increases, so that suction takes place. The working chamber 4 is connected to the inlet channel of the bearing cover 16 and the intake port 19, since the slot 21 releases the channel 23 (see also FIG. 2). The Anaaugen lasts as long as the volume of / rbaltskammer increases and as long as the channel is open 23 via the slot 21 · In presenting Fi ₁ ^. 4 lot the suction stroke is completed. The working chamber 4 is closed because the slot 21 has overflowed the channel 23. With continued movement of the rotor 5, the gases in the chamber 4 are compressed, since the volume of the chamber 4 is steadily decreasing up to the division of FIG. 5. This is where the ignition or fuel injection takes place, so that the working stroke now begins, when the rotor 5 is driven from the position in FIG. 5 to the position in FIG. 6.

The internal combustion engine may well be a gasoline engine, although spark plugs and the ignition system are not shown are. Since the play between the rotor and the working chamber can be adjusted according to v.'unsoh, the lower limit is For the dimensions of the working chamber, the envelope curve the rotor defines a predetermined movement.

B., if the seal is accommodated in the stationary housing and the sun gear has internal teeth, this distance cannot exceed a value that is · ■■ · times the diameter of a Krrtisee that envelops the rotor, where η is the ratio zv / ischan is the diameters of the sun gear and planet gears. The fact that the eccentricity and thus also the diameter of this sun gear 9 is independent of the diameter of the planet gear 7 is shown in FIG. 1, in which the diameter of the three planet gears 7 can be thought to be, for example, twice as large as the drive shaft is rotated, the primary rotational movement of the .ίοtors (which results directly from the rotation of the drive shaft) always remains the same as in the Pig. 1. Since the eccentricity is also the same, the center of gravity of the rotor moves on the same circle with the same speed. The eccentricity and the diameter of the planet gears are therefore independent quantities. The protruding vfellenzapfen 6 can be attached so.vohl inside as well as outside of the pitch circles of the planetary gears. In practice, this means that the dimensions of the gear (sun gear and planetary gears) and of the rotor and the eccentricity can be changed independently of one another to meet all requirements regarding the volume of the chambers, the torque, the pressure between the teeth "4jr gears, etc. to be sufficient
