Definitions
- the present invention relates to an engine for oscillating displacement machines, such as diaphragm pumps, with an eccentric shaft and a plurality of piston rods, wherein the piston rods are so in communication with the eccentric shaft, that rotation of the eccentric shaft causes an oscillating linear movement of the piston rods.
- Oscillating machines are usually built according to the principle of the Geradschubkur- geretriebes. At high power, or to keep the oscillating, acting on the machine foundation mass forces small, such machines are usually designed as a multi-crank engine.
- the individual eccentric with connecting rod and piston rods, either in a row or boxer or star shape are arranged side by side and are driven by a common crankshaft, the eccentric are offset by the same angle to each other.
- the engine has a large overall volume, a high weight and high production costs.
- DE 85 21 520 describes a multi-cylinder diaphragm pump with a plurality of diaphragm pump heads, each having an actuatable by a hydraulic piston diaphragm.
- the pump drive takes place via a connecting rod eccentric device.
- the connecting rod is rotatably coupled to both the piston and the piston rod and the eccentric shaft, whereby the engine is expensive to manufacture.
- US-5,368,451 describes a corresponding device with three hydraulic cylinders, in which the piston rod is pressed by means of a return spring on the eccentric surface.
- DE 196 26 938 A1 describes a star-shaped piston-cylinder arrangement in which the shaft is surrounded by radially aligned cylinders in which displaceable pistons are arranged, which are connected by connecting rods via an eccentric with the shaft.
- a slotted guide consists of a backdrop, which has a slot, a web or a groove, and a correspondingly formed sliding block, which is forcibly guided by the backdrop.
- all the piston rods lie in one plane, wherein the piston rods are particularly preferably arranged in a star shape.
- star-shaped in the context of the present application, it is understood that the piston rods are equally spaced from each other in the circumferential direction of the eccentric shaft. In other words, adjoining adjacent piston rods in a projection on a plane perpendicular to the eccentric shaft in each case the same angle.
- the slotted guide is designed such that eccentric shaft and piston rods are positively connected to each other in a first spatial direction, preferably in a second direction perpendicular thereto spatial direction, while a relative movement in a third spatial direction perpendicular to is arranged first and second spatial direction is possible.
- the backdrop may be formed as a T-slot and the sliding block as a correspondingly adapted sliding block. It has been shown that the link is preferably arranged on the piston rod and the sliding blocks are preferably attached to the eccentric shaft.
- the eccentric shaft may be connected to a link element (eg rotatable), which has the slotted links or the sliding blocks, the slotted links or the sliding blocks lying on the boundary surfaces of a regular polygon with n corners.
- the backdrop is preferably made of hardened steel.
- the sliding block is best made of a copper alloy, preferably made of bronze, in order to allow the lowest possible movement of the sliding block in the backdrop.
- the disadvantages mentioned above are eliminated in that the piston forces for both the pressure stroke and the suction stroke di-. - A - rectly from the eccentric link, which is rotatably connected to the eccentric shaft are transmitted to the individual piston rods, which additional components, such as an expensive retraction rod or connecting rods, accounts and so the size of the entire engine can be significantly reduced.
- Figure 1 shows a first embodiment of a Exzenterkulissen engine according to the
- FIG. 2 shows a further sectional view perpendicular to the view shown in FIG. 1,
- FIGS. 3a-c show three variants of the engine according to the invention.
- Figures 4a + b and 5 a + b different embodiments of the connection between the piston rod and link element.
- the engine is used to drive a three-cylinder engine.
- the engine thus has three piston rods 1, which lie in a plane and are offset by 120 ° from each other.
- the eccentric shaft 2 is rotatably connected to a Exzenterkulisse. If the eccentric shaft is rotated about the axis 12, the center point 1 1 of the eccentric cam will move on the circle provided with the reference numeral 13. In other words, the eccentric cam performs a translatory circular motion.
- the link element 6 is preferably triangular in shape, wherein on the three sides of the triangle, the sliding blocks or sliding blocks are arranged, the sliding surfaces 8 have.
- the piston rods 1 have corresponding sliding shoes 5, which serve as a backdrop.
- the slide shoe 5 surrounds the sliding blocks of the link element 6, so that the sliding surfaces 8 of the sliding blocks bear against the sliding surfaces 7 of the backdrop.
- the sliding blocks of the link element 6 are thus positively embraced by the shoe 5.
- the sliding blocks 5 Upon rotation of the shaft 2, the sliding blocks 5 will slide along the sliding surfaces 8 of the sliding blocks.
- almost no transverse forces are applied by the eccentric shaft to the piston rods 1.
- FIG. 3 a shows a two-cylinder drive.
- the engine therefore has only two piston rods 1.
- the link element 6 ' here has a rectangular shape, with corresponding sliding surfaces provided with sliding surfaces are arranged only on two opposite sides of the rectangle, which are encompassed by the shoes 5 of the piston rods 1. at a rotation of the shaft, the center 1 1 of the link element 6 'will move along the circle 13.
- Figure 3b shows the already known from Figures 1 and 2 embodiment with three cylinders.
- FIG. 3c shows a four-cylinder drive.
- the gate element 6 is similar to the gate element 6 'of the embodiment of Figure 3a, but here on all four sides of the square gate element 6" corresponding sliding surfaces 11 supporting sliding blocks are arranged, which are each embraced by a shoe 5 of the four piston rods 1.
- FIGS. 4a and 4b show an enlarged view of the slotted guide.
- the piston rods 1 have at their end a pressure plate 5 ', which together with the remindholklauen 14 form the shoe.
- the return claws 14 are fastened by means of a screw to the pressure plate 5 '. In the embodiment shown in FIG. 4a, the return claw 14 is screwed onto the pressure plate 5 'at the end.
- the return pawl 14 is U-shaped, so that it surrounds both the sliding block and the pressure plate 5 '.
- the return claw 14 is then from behind, d. H. from the side facing away from the sliding block of the pressure plate 5 'screwed with this.
