Definitions

• the tilting pixel of the piston in a reciprocating machine e.g. in a four-stroke piston engine
• Constructions in which the pistons are suspended on guided rods that run in linear bearings and end on one side in a crosshead are known. They were mainly used for locomotives. According to the above-mentioned constructions, lubrication is present in the work room or in the rooms adjoining the work room.
• the design known as the Philips rhombic gearbox from RJ MEIJER (DE-AS 1080351) *, requires hardly any lubrication in the working area of the pistons.
• the gears are lubricated or greased in order to reduce the much higher friction of the 21 ) rhombic gearbox caused by the gears.
• lubrication of the piston or the piston rods is necessary in order to prevent parts from seizing.
• Piston suspension for one working as a motor or pump
• the play between the piston and cylinder can be dimensioned so small that no lubrication between the piston and cylinder is necessary, no significant wear of dry 5 sealing rings occurs and a seal of
• Piston housing or piston guide rods can be omitted.
• the invention is based on a reciprocating piston machine, in particular an engine or pump, i) with one or two pistons per cylinder and for each
• Pistons with a power transmission each consisting of a connecting rod or diamond and a crank.
• the invention consists in that at least one third power transmission, consisting of connecting rod and crank, per piston
• crankshafts are not congruent with the axes of the crankshafts for the first and second power transmission.
• a disk-shaped 21) piston bearing ring is provided, on which the piston is supported at one end and the connecting rods.
• the piston bearing ring is provided with a recess corresponding to the piston shape, the diameter of which is small
• Amount is larger than the diameter of the piston, so that the piston can be assembled and disassembled through the piston bearing ring.
• the piston suspension consists of three connecting rods with crankshafts that form a tripod, for example. Exemplary embodiments of the invention are shown in the drawings. Show it:
• Fig. 1 is a perspective view of one with three
• 1A is a view of a piston, which is mounted on only 1u of a connecting rod, with associated associated force vectors.
• Fig. 2 is a perspective view of the
• Fig. 3 is a perspective view of one with eight
• u Fig. 4 is a perspective view of the
• the suspension of the piston 1 of a reciprocating piston machine 5 is shown, the piston 1 being mounted on three connecting rods 21, 22, 23.
• the connecting rods 21, 22, 23 are all of the same length in this case and are mounted on the three cranks 31, 32, 33.
• the crankshafts 34, 35, 36 of the cranks 31, 32, 33 do not lie on a straight line and also do not have to be connected to one another, as is the case, for example, in the case of a rhombic transmission Downward movement in relation to the friction between the piston 1 and the cylinder wall is supported with almost no play
• crankshafts 34, 35, 36 do not have to be in the same alignment or parallel lie to each other.
• the offset of the at least three cranks 31, 32, 33 can also be different.
• Pistons 1 transmit the force component D to the crank 31 through the connecting rod 21.
• a counterforce ⁇ B arises on the piston 1, which also causes the piston 1 to be perpendicular to it
• Piston suspensions wear. In the case of the invention 5, this force is intercepted by counter forces of the two connecting rods 32, 33 and completely balanced. The forces acting sideways and perpendicular to the direction of movement of the piston 1 do not occur on the piston 1. They are now transmitted to the crankshafts 34, 35, 36 and no longer have an i) wear-and-tear effect between the piston 1 and the cylinder. It should also be mentioned that the disadvantageous additional effort of three crankshafts 34, 35, 36 compared to one crankshaft up to now has the advantage that the cranking of the cranks 31, 32, 33 can be kept smaller than the stroke. Also the individual crankshaft 34 , 35, 36 less burdened. This leads to the simplification of the crankshaft 34, 35, 36 and their storage.
• FIG. 2 shows the piston holder according to FIG. 1 with the piston 1 removed. From this it can be seen that the piston 1 is surrounded and clamped at its lower end by a bearing ring 37. If the bearing ring 37 is opened, the piston 1 can go down pulled through the bearing ring 37 and replaced.
• crankshafts running parallel to one another will be selected.
• a piston suspension with four crankshafts 51, 52, 53, 54 and four split connecting rods 61-68 is therefore shown.
• the four crankshafts .51, 52, 53, 54 are all in alignment.
• the cranking of the eight cranks 41-48 is about a third of the stroke.
• the connecting rods 61-68 are divided and the bearing rings 71, 72, which are located in two planes, are fastened to the outside of the piston 1 to achieve additional stability.
• crankshafts 51, 52, 53, 54 can be dimensioned smaller because of the rare use of the piston center line and because of the forces.
• the offset of the crankshafts 51, 52, 53, 54 also reduces the cranking of the cranks 41-48.
• the crankshafts 51, 52, 53, 54 lying sideways to the piston center line lead to a more favorable attack of the forces on the crankshafts 51, 52, 53, 54.
• a connecting rod 61-68 acts in a conventional reciprocating piston engine at the top and bottom dead center of the piston 1 largely radially on the crankshaft, this is significantly cheaper in the invention depending on the size of the deflection.
• the tangential forces clearly outweigh the radial forces on the. " Crankshaft.
• seals can now be used which run dry and are no longer subject to wear after a certain running-in period, which can lead to engine failures or leaks.
• FIG. 4 shows the piston suspension according to FIG. 3 with the piston 1 removed.
• the piston 1 is gripped and clamped at its lower end by two bearing rings 71, 72 lying in two planes in a particularly tilt-proof manner. If the bearing rings 7, 72 are opened, the piston 1 can also be pulled down through the bearing rings 71, 72 and exchanged in this exemplary embodiment.
• the arrangements of the connecting rods according to FIGS. 1-4 enable the actual piston 1 in a very short time
• the piston can be fastened to the bearing ring 37 or to the bearing rings 71, 72 or the piston suspension by means of a thread, bayonet lock, screws or other technically known methods.
• pistons can also be mounted on a crankshaft set, e.g. B. with two counter-rotating or offset pistons in a cylinder.
• the number of connecting rods can also be increased as required.
