Definitions
- the invention relates to the control of the piston of a rotary piston engine with a single-arched trochoid as a housing track.
- rotary piston engines For large volume changes are particularly suitable rotary piston engines whose housing career have the shape of a single-arched trochoid.
- the piston of the machine has a two-cornered shape.
- a disadvantage is that, if the openings for the media change are unsuitable, short-circuit flows can occur between inlet and outlet. These short-circuit flows can be avoided by changing the media via side openings in the side wall of the housing.
- the two-cornered flask has only a small area and it is difficult to arrange the side openings so that they be covered or opened at the same time in connection with the movement of the piston.
- Circular piston engines with the housing track in the form of a single-arched trochoid which is explained with reference to Figure 1.
- a special feature of this rotary engine is given in the ratio of 2 to 1 in the translation of the two gears.
- the mathematical law of education now causes a longitudinal axis 6 projecting through the piston to always run through a housing-fixed point 3, and a transverse axis 7 passing through the piston always through a housing-fixed point 4.
- the points 3 and 4 are at the same time points of a Cartesian coordinate system For the rotation of a power shaft with the center point 5, it does not matter whether the rotation of the piston about itself by the interaction of two gears 10 and 11 or by sliding guides the piston through the points 3 and 4 are effected.
- Figure 2 shows that other pivot points can be selected on the side wall of the housing for the function of the rotary slide guide.
- the axes 12 and 13 pass through the pivot points 14 and 15.
- the axes 12 and 13 are rotated relative to the symmetry axes 6 and 7 in Figure 1 by an angle. This angle can be chosen arbitrarily according to the selected position of the rotary slide points on the housing side wall.
- Rotary piston engine with a single-curved housing contour with gears next to the piston is an elegant and safe solution is taken away both by a continuous power shaft and non-continuous power wave by the arrangement of a large internal gear next to the eccentric a large area that is no longer for the purposes of Media change on the piston side surface is available.
- the aim of the invention is to provide solutions as can be designed by other control systems of the media change on the side surfaces, especially in very small machines and waiving a continuous power wave.
- Sliding guide is arranged in the interior of the piston, that only a guide pin, which is arranged in the housing side wall, protrudes through a minimum central opening in the side surface of the piston in the piston and forms a rotary sliding guide in an inner space of the piston with guide tracks.
- the inventive solution is that in the piston side a straight, running over the piston center groove is incorporated at any angle, in which a simultaneously serving the media supply pivot is arranged.
- the pivot pin is designed as a tube and angeflächt at the cross-groove in the groove groove width.
- the media supply into the machine is controlled by the pipe channel as soon as a certain position between the pivot and guide groove or a certain angle of rotation of the piston is reached in the movement, such that by a piston located in the duct line, which then coincides with the pivot, the Medium is directed into a working space of the machine.
- Another inventive feature is that the control of the piston kinematics is carried out by two double cross loops in the plane of movement of the piston are arranged so that two sliding blocks, which are interconnected by a joint coupling, can run in both cross loops, while The piston and a turntable, in which one of the cross loops is located, rotate in the same direction of rotation at the same angular velocity.
- the centers of the joint bearings of the coupling have the distance of the eccentricity of the machine, given by the distance between the center of the eccentric in the piston and the center of the power shaft and the housing-fixed cross loop has a common axis of rotation with the power shaft.
- An inventive feature is also that a housing-fixed cylindrical pin projects into a lateral central piston opening and in the middle of the opening another cylindrical piston-solid pin is arranged, that the piston-fixed pin has twice the diameter of the housing-fixed pin and in that both Have a pin teeth and a toothed belt around both pins, so that during the rotation of the piston takes place a relative rotation about the power shaft.
- the lateral opening in the piston ensures a large free area in the piston for the arrangement of organs for the media change in the housing wall.
- Piston kinematics in that, instead of a toothed belt, a toothed wheel as an intermediate wheel connects both toothed pins.
- the piston 1 is seated on the eccentric 19. He has on the side facing away from the power shaft a passing through the piston center groove with the guideways 17, with which the sliding block 18 is guided.
- the pivot pin 16 protrudes into the piston 1 in such a way that the slideways 17, which occupy a larger space, do not reduce the lateral area on the piston 1 for a lateral media control beyond the necessary degree of freedom of movement of the pivot pin 16.
- This embodiment of the piston guide connects the principle of the rotatably seated on the fixed pivot sliding block 20 with the direct media supply via the pivot 21.
- the pivot pin 21 has the bore 22 and the lateral opening 23 for supplying the medium to the sliding block 20th In a certain position comes on the rotation of the piston 1 of the sliding block 20 to coincide with the opening 23 of the pivot 21 and the upper, narrow working space of the machine facing channel 25.
- the angle of rotation and the duration of the feed can be changed in an operationally appropriate manner.
- the cross loop 26 In the interior of the piston 1 and in the lateral piston center is the cross loop 26, in which the sliding blocks 28, 29 run.
- the sliding blocks 28, 29 are designed as double stones, which have in the middle a shaft piece, which serves as a storage for the joint coupling 30.
- the sliding blocks 28, 29 run in the cross loop 27. Between two cross loops there is a distance in the planes, which allows the passage of the joint coupling 30.
- Turntable 31 in which the cross-bow 27 is arranged, has its housing-fixed pivot point 5, through which at the same time the axis of rotation of the power shaft of the machine runs.
- the distance between the centers of the bearings of the joint coupling 30 is identical to its eccentricity for a einbogige Trochoidenmaschinebahn a rotary piston engine.
- the bore 34 is incorporated with the corresponding component height.
- the running of the piston 1 in the Trochoidenlaufbahn of the housing 2 is achieved here by a fixed housing fixed cylindrical pin 16 is disposed in the lateral housing part of the machine, which sits in alignment with the power shaft axis and projects into an opening 32 of the piston 1 so, that upon rotation of the piston about its axis clearance exists.
- In the opening 32 is located in Achsfrowung to the piston axis of the cylindrical piston-fixed pin 36.
- the ratio of the diameter of the two pins is 1 to 2 and thus corresponds to the mathematical condition for the generation of a einbogigen trochoid.
- Pin 16 on the housing and pin 36 on the piston 1 are provided with a toothing, so that a toothed belt can be placed around both pins, which generates slip-free upon rotation of the power shaft rotation of the piston 1 about its axis with the same direction half angular velocity of the power wave , With the dimension of the opening 32 a minimum restriction of the lateral piston surface can be achieved.
- the arrangement corresponds to a three-shaft epicyclic gear consisting of the gear 38 which is concentrically mounted on the housing-fixed pin 16, the piston-fixed gear 39 which is aligned with the piston axis and the intermediate gear 40 and the gear 41 fixed to the web Gear ratio of the wheels 38 and 39 is 1 to 2, so that upon rotation of the power shaft of the piston 1 with the half angular velocity rotates in the same direction.
- the gear assembly can be housed in a minimal opening 32 (see Figure 13) laterally in the piston.
