Definitions

  • the invention relates to a thermodynamic reciprocating engine of the displacer-piston type, comprising at least one pair of identical cranks each located on one side of a plane going through the center line of the engine and forming part of two crank shafts which rotate in synchronism in co-phase and in relatively opposite directions.
  • the center lines of the shafts are parallel to each other and are located symmetrically one on each side of the plane going through the center line of the engine in a plane at right angles to said center line.
  • Each pair of associated cranks is connected with at least one piston and at least one displacer co-operating with the former, while the connection between each of the cranks and the pistons and displacers respectively includes a piston connecting rod and a displacer connecting rod respectively.
  • the rectilinearly moving parts of the piston connecting rods being located on one side and the rectilinearly moving parts of the displacer connecting rods being located on the other side of the plane going through the center lines of the crank shafts.
  • hot gas reciprocating engine as used herein not only denotes hot-gas engines but also cold-gas refrigerators and heat pumps, operating on the inverse hotgas engine principle.
  • the synchronization of the two crank shafts is obtained by providing, on each of the crank shafts, a gear wheel so that the two gear wheels engage each other.
  • One of the crank shafts of such a machine is coupled with the driving or the driven machine, whereas the other crank shaft transfers its torque via the gear wheels to the other crank shaft.
  • the gear wheels are therefore used for the transfer of torque. Since the two crank shafts will have unequal inertia moments and since the torque fluctuates, the tooth and bearing tolerances will have to meet very severe requirements in view of the noise level. It will be obvious that the number of revolutions of the engine and that of the driving or driven machine will, in general, differ from each other, so that a comparatively expensive reducing member is required between the crank shaft and the driving or the driven machine.
  • the invention has for its object to provide an improved structure of the hot-gas'reciprocating engine of the kind set forth and is characterized in that the two crank shafts are connected with each other by the provision of a worm and a worm wheel thereon, each of which engages a worm wheel and a worm respectively on a third shaft, which crosses the crank shafts and which establishes a coupling between the hot-gas reciprocating engine and the driving or the driven machine.
  • An advantage of the construction according to the invention consists in that the worm and worrn wheel transice mission is capable of providing not only the synchronization of the numbers of revolution of the crank shafts, but also, with a suitable choice of the dimensions, a correct transmission ratio between the number of revolutions of the hot-gas reciprocating engine and that of the driven or the driving machine.
  • the expensive reducing gear required in the known construction between the crank shaft and the driven or the driving machine is thus dispensable.
  • a further advantage of the worm and worm wheel transmission is that since simultaneously a plurality of teeth of the worm wheel engage the worm such a transmission gear produces only little noise. This is particularly favorable with hot-gas reciprocating engines which themselves operate substantially without noise or vibrations.
  • a further advantage of the hot-gas reciprocating engine according to the invention resides in that the third shaft can occupy a position in which it is parallel to the plane of the crank shafts. This is particularly advantageous in hot-gas reciprocating engines mounted in a ship in horizontal position, in which case the driving gear is arranged so that the crank shafts are located one above the other and extend substantially parallel to the bottom of the vessel. Under certain conditions it may be desirable for the propulsion to employ a screw driven by a vertical shaft. In accordance with the invention the third shaft can be directly employed to this end.
  • the third shaft intersects the plane going through the crank shafts.
  • the third shaft (output shaft) may then extend parallel to the center line of the cylinder, in contrast to known structures in which the output shaft crosses the center line of the cylinder at right angles. This may bring about a great advantage, for example, if a hot-gas reciprocating engine has to be built in a low-roofed space, for instance below the bottom of a vessel in horizontal position.
  • a further embodiment of the hot-gas reciprocating engine according to the invention has the feature that each pair of piston connecting rods has two pistons and each pair of displacer connecting rods has two displacers, said pistons and displacers being all located on the same center line, while the head faces of the pistons and displacers are remote from each other.
  • a further advantageous embodiment of the hot-gas reciprocating engine according to the invention is characterized in that the engine comprises at least two pair or" associated cranks, each pair of cranks being connected with two pistons and two displacers, the pistons and displacers connected with one pair of cranks having a common center line, the head faces of said pistons and displacers being remote from each other, the center line of the pistons and displacers connected with one pair of cranks being parallel to the center line of those connected with the other pair of cranks.
  • a further embodiment of the hot-gas reciprocating engine according to the invention is characterized in that it comprises at least two pairs of crank shafts, the crank shafts of each pair being parallel to each other and adapted to rotate in synchronism in opposite directions and in co-phase, while the pairs. of crank shafts are arranged in parallel planes at a small distance from each other, so that the crank shafts of one pair cross those of the other pair. Furthermore, each pair of crank shafts has at least two pairs of associated cranks and each pair of cranks is connected with two pistons and two displacers, the head faces of said pistons and clisplacers being remote from each other, while those pistons and displacers which are connected with one pair of cranks have one common center line, all common center lines being parallel to each other.
  • the engine comprises a third shaft, which intersects the planes going through the crank shafts and is provided with a widened worm wheel or widened worm or a plurality of worm wheels or worms respectively, which co-operate with worms and worm wheels respectively on each of the crank shafts.
  • a plurality of hot-gas reciprocating engines according to the invention are arranged in line with the third shaft and around the latter in horizontal positions.
  • the hot-gas reciprocating engine according to the invention comprises two coaxial third shafts, one of which is accommodated at least partly inside the other, the two shafts being provided with one or more worm wheels and worms respectively, which cooperate with worms and worm wheels respectively on the crank shafts of one or more of the hot-gas engines arranged around said shaft.
  • This embodiment has the advantage that two output shafts are available which are capable of rotating with different speeds.
  • the third shaft intersects the plane(s) of the crank shafts at an angle deviating from 90 while said third shaft is provided with two worm wheels and two worms or a widened worm wheel or a widened worm, which cooperate with worms or worm wheels respectively on the crank shaft.
  • This is favorable for a flat twin engine of the thermodynamic reciprocating type, in which the third shaft is not located in the plane going through the center lines of the two cylinders, but slightly beyond said plane. The distance between the cylinders may then be particularly small, which is advantageous with the space to be occupied.
  • a further advantage resides in that particularly in ships the third shaft leading to the screw must always extend slightly downwards. is solved by arranging the engine itself at an angle.
  • the hot-gas reciprocating engine can then be arranged normally in the horizontal position, while the output shaft is at an angle to the horizontal plane.
  • the crank shafts of a hot-gas reciprocating engine will usually be provided with worms, while the third shaft will be provided with a worm wheel.
  • the number of revolutions of a cold-gas refrigerator will usually be lower than the number of revolutions of the driving machine.
  • the third shaft will usually be provided with a worm and the crank shafts will have worm wheels.
  • FIGS. 1, 2 and 3 are three cross sections of a hot-gas reciprocating engine.
  • FIGS. 4 and 5 show diagrammatically a four-cylinder hot-gas engine, the former in cross-section and the latter in elevation.
  • FIG. 6 shows diagrammatically an advantageous arrangement of an eight-cylinder hot-gas engine.
  • FIGS. 7 and 8 show an eight-cylinder hot-gas engine in which the cylinders are arranged around the output shaft.
  • FIGS. 9 and 10 show a two-cylinder hot-gas engine in which the output shaft is parallel to the plane going through the crank shafts.
  • reference numeral 1 designates a cylinder, in which a displacer 2 and a piston 3 are adapted to reciprocate with phase difference.
  • the piston 3 varies, during its displacement, the volume of a compression space 4 and the displacer varies with its head face the volume of an expansion space 5.
  • the compression space 4 and the expansion space 5 communicate with each other through a cooler 6, a regenerator 7 and a heater 8. Heat is supplied to the head of the cylinder 1 and the heater 8 through a burner 9.
  • the piston 3 is connected through a piston rod 10 with a yoke 11.
  • the displacer 2 is connected through a displacer rod 12 with a yoke 13.
  • the yoke 11 is connected via piston connecting rods 14 with the cranks 15 of the crank shafts 16.
  • the yoke 13 is connected through displacer connecting rods 17 also with the cranks 15.
  • the crank shafts 16 are provided with worms 18, which cooperate with a worm wheel 19 on a third shaft 20.
  • the third shaft 20 is coupled with a shaft 21 of a driven machine 22.
  • the torque of the crank shafts 16 will be trans ferred through the worms 18 to the worm wheel 19 and hence to the output shaft 20.
  • the worms 18 and the worm wheel 19 have a double function i.e. the synchronization of the crank shafts 16 and the transfer of torque from the crank shafts 16 to the driven shaft 20.
  • An advantage of this hot-gas engine is that the center line of the cylinder 1 and that of the driven machine are parallel to each other, so that a horizontal hot-gas engine may be constructed with a very small height. This is important for example in ships, Where the engine may be accommodated below the floor.
  • FIGS. 4 and 5 show diagrammatically a four-cylinder hot-gas engine.
  • the cylinders are designated by 31, 32, 33 and 34.
  • the continuous crank shafts 35 are provided with worms 36, which cooperate with the worm wheel 37.
  • the worm wheel 37 occupies an oblique position and is widened, so that the output shaft 38 is at an angle to the plane going through the center lines of the cylinders.
  • the resultant construction is a hot-gas engine which also has a very low structural height and which is particularly suitable for being accommodated below the floor of a vessel or water craft.
  • a further advantage of this construction is that the shaft 38 is at an angle to the plane going through the cylinders.
  • the cylinders 31 and 32 may therefore have a smaller distance between their center lines than in the case in which the shaft 38 is located in the plane of these cylinders.
  • a further advantage is that the shaft 38 can be directly coupled with a machine located slightly outside the plane going through the center lines of the cylinders. This may be the case in ships in which the engine is located at a higher level than the screw. According to the invention it is now possible to couple the engine directly with the screw through the shaft 38, without the need for an oblique position of the engine. It will be obvious that the crank shafts 35 may be extended at will on both sides and may be provided with cranks. The engine may thus be extended on either side and further pairs of cylinders, so that eight or twelve cylinder hot-gas engines are obtained. FIG.
  • crank shaft 40 shows diagrammatically the possibility of providing a third shaft 40 with for example two worm wheels 41 and 42, with which worms 43 and 44 cooperate, arranged on crank shafts 45 and 46 respectively.
  • crank shafts 45 and 46 are provided with cranks forming part of rhombic driving gears of hot-gas engines. This provides an arrangement which is particularly suitable for accommodation in a low-roofed, narrow space.
  • FIGS. 7 and 8 show a hot-gas engine having two output shafts 50 and 51.
  • the shaft 50 is accommodated for the major part inside the .hollow shaft 51.
  • the two shafts 50 and 51 are provided with worm wheels 52 and 53 respectively, with which co-operate the worms 54 and 55 respectively.
  • the worms 54 are provided on the crank shaft 56 forming part of the driving gears of the hot-gas engine cylinders 57 and 58.
  • the worms 55 are arranged on the crank shafts 59, which form part of the driving gears of the hot-gas engine cylinders 60 and 61.
  • the pitch angle of the worms 54 may be chosen so with respect to the pitch angle of the worms 55 that the shafts 50 and 51 rotate in the same directions.
  • the worms con cerned may, however, also be chosen so that the shafts 50 and 51 rotate in opposite directions, which may be important for the propulsion of ships. From FIG. 8 it will be seen that the cylinders 57, 58 and 60, 61 are arranged symmetrically around the center of the engine. In this manner a very compact construction of the hot-gas engine is obtained, which is extremely suitable for accommodation in a cylindrical, elongated space.
  • FIGS. 9 and show two cylinders 90 and 91 of a hotgas engine.
  • the pistons 92 and displacers 93 are capable of reciprocating with phase difference.
  • the volumes of a compression space 94 and of the expansion space 95 are varied.
  • Said spaces communicate with each other through a cooler 96, a regenerator 97 and a heater 98.
  • Each of the pistons and displacers is connected through a piston rod 100 and a displacer rod 101 respectively with a rhombic driving gear.
  • This rhombic driving gear comprises the yokes 103 and 104 with which the pistons and displacers respectively may be coupled.

  • the piston and displacer movements are transferred through the yokes 103 and 104 respectively and connecting rods 105 and 106 respectively to the crank shafts 107 and the movement of the crank shafts is transferred through the worms 108 and the worm wheels 109 to the output shaft 110.
  • This provides an extremely simple coupling between the crank shafts and the output shaft and by suitable choice of the worms and the worm wheels the correct transmission ratio is obtained.
  • the worms and worm wheels ensure furthermore that the crank shafts rotate in synchronism and in opposite directions. It should be noted here, that, since the crank shafts rotate in opposite directions, the pitches of the two worms or of the two worm wheels must be opposite each other.
