Definitions

  • the present invention relates to an oil sump for a piston engine in accordance with the preamble of claim 1 .
  • the invention also concerns an oil sump ar- rangement according to the preamble of the other independent claim.
  • Oil sumps of internal combustion engines can be either wet sumps or dry sumps.
  • the main function of a wet sump is to be an oil reservoir for the engine.
  • dry sump designs the engine is provided with a separate oil reservoir, into which the oil is introduced from the oil sump.
  • the oil sump is in many engines an important part of the whole engine structure. Cracks and other problems in the oil sump are very difficult to detect while the engine is in use, and therefore the design must be robust.
  • oil sumps are attached to the engine blocks by means of support beams, which are arranged on the upper surfaces of the side walls of the oil sumps.
  • the support beams are welded together with transversal partition walls, which divide the oil sump into compartments.
  • the weld seams between the partition walls and the support beams are subjected to very high fatigue stress, which is mainly a result of the vibrations and displacements of the engine block. Therefore, a very high quality of the weld seams is required. Also some additional treatment of the weld seams may be needed in order to ensure sufficient resistance against failures. All this increases the costs of the construction.
  • An object of the present invention is to provide an improved oil sump for a piston engine.
  • the characterizing features of the oil sump according to the inven- tion are given in the characterizing part of claim 1 .
  • Characterizing features of the oil sump arrangement are given in the characterizing part of the other independent claim.
  • An oil sump according to the invention comprises a bottom plate, side walls and end walls encircling the bottom plate, and at least one partition wall, which partition wall is arranged between the side walls of the oil sump for dividing the oil sump into compartments. Both ends of the partition wall are provided with a curvilinear cutting opening towards the longitudinal center line of the oil sump.
  • An oil sump arrangement comprises an oil sump defined above.
  • the arrangement is provided on both sides of the oil sump with a support beam for fastening the oil sump to an engine block, which support beam is arranged above the partition wall and fastened to the partition wall by a weld.
  • each end of the partition wall is provided with a protrusion extending away from the bottom plate, and the cut- tings are arranged in the protrusions.
  • at least part of the cutting is a segment or a sector of a circle, of which radius is 1 .5-2.5 times the thickness of the partition wall.
  • the radius is 1 .8-2.2 times the thickness of the partition wall.
  • the height of the weld in the oil sump arrangement is 0.5-1 .5 times the thickness of the partition wall.
  • the height of the weld is 0.8-1 .2 times the thickness of the partition wall.
  • the support beam extends over the weld towards the center line of the oil sump a distance, which is 0.5- 1 .5 times the thickness of the partition wall.
  • the distance is 0.8-1 .2 times the thickness of the partition wall.
  • Fig. 1 shows an oil sump according to the invention in connection with an en- gine block
  • Fig. 2 shows a cross-sectional view of the oil sump of figure 1
  • Fig. 3 shows an enlarged view of a detail of the oil sump
  • Fig. 4 shows dimensioning of the detail of figure 3.
  • an oil sump 1 according to an embodiment of the invention in connection with the engine block 1 1 of an internal combustion engine 10.
  • the engine 10 is a large piston engine, which could be used, for instance, as a main or an auxiliary engine of a ship or at a power plant for producing electrici- ty.
  • the cylinders 12 of the engine 10 are arranged in a V-configu ration, but also other cylinder configurations could be used.
  • the oil sump 1 is a wet sump 1 .
  • the crankcase 13 of the engine 10 is used as a reservoir for oil.
  • the invention is also applicable to dry sump constructions, in which external oil reservoirs are used.
  • FIG 2 is shown a cross-sectional view of the oil sump 1 of figure 1 .
  • the oil sump 1 is a trough-shaped part, which can accommodate a relatively large amount of oil.
  • the oil sump 1 comprises a bottom plate 2, which is encircled by a first and a second side wall 3a, 3b and a first and a second end wall 4a, 4b.
  • the bottom plate 2 comprises a straight middle section 2a and inclined side sections 2b, 2c.
  • the side sections 2b, 2c are further divided into two sections so that the outer of the two sections is inclined more than the inner section in relation to the horizontal plane.
  • the bottom plate 2 is thus bent and rises towards the sides of the oil sump 1 , which helps to col- lect the oil towards the middle of the oil sump 1 .
  • the bottom plate 2 can be made of one or several pieces.
  • the side walls 3a, 3b are integrated into the same part as the bottom plate 2 or part of it.
  • the side walls 3a, 3b are inclined slightly outwards. However, they could also be straight, i.e. at right angle relative to the horizontal plane.
  • the oil sump 1 is provided with partition walls 5, which divide the oil sump 1 into compartments 7.
  • Each partition wall 5 extends from the first side wall 3a to the second side wall 3b.
  • the height of the partition wall 5 increases slightly towards the sides of the oil sump 1 .
  • the upper edges of the partition walls 5 are inclined in relation to the horizontal plane.
  • the sidewall ends of the partition walls 5 are further provided with protrusions 5b, which extend away from the horizontal plane. The protrusions 5b thus increase the height of the partition wall 5 at the ends at the partition wall 5.
  • the partition walls 5 are provided with openings 9 for allowing oil flow between compartments 7 and for accommodating pipes that are arranged in the oil sump 1 for different purposes.
  • the partition wall 5 can be made of a single piece of material, or it can be composed of several parts.
  • the partition walls 5 could also be integral parts of an oil sump casting.
  • the oil sump 1 is fastened to the engine block 1 1 by means of support beams 6a, 6b, 6c, 6d, which are arranged between the oil sump 1 and the engine block 1 1 .
  • Each end and side of the engine 10 is provided with a support beam 6a, 6b, 6c, 6d.
  • the support beams 6a, 6b, 6c, 6d are fastened to the oil sump 1 by welding.
  • welds 12 are arranged between the support beams 6a, 6b and the protrusions 5b of the partition walls 5.
  • each partition wall 5 is provided with a curvilinear cutting 5a at both ends of the partition wall 5.
  • the cutting 5a is arranged in the protrusion 5b and opens towards the longitudinal center line 8 of the oil sump 1 .
  • Figure 4 shows an enlarged view of the cutting 5a.
  • the cutting 5a is a segment of a circle.
  • the radius R of the circle is 1 .5-2.5 times the thickness of the partition wall 5, preferably approximately two times, for instance 1 .8-2.2 times the thickness of the partition wall 5.
  • the distance of the bottom i.e.
  • the outermost part of the cutting 5a is at least 1 .5 times the radius R of the circle from the end of the partition wall 5.
  • the width of the support beam 6a is greater than the width of the protrusion 5b of the partition wall 5 and the length of the weld 12 between the support beam 6a and the partition wall 5.
  • the length of the weld 12 is approximately the same as the width of the protrusion 5b.
  • the support beam 6a extends a distance X over the inner edge of the protrusion 5b.
  • the weld 12 extends to the same dis- tance X from the inner edge of the support beam 6a.
  • the distance X is 0.5-1 .5 times the thickness of the partition wall 5.
  • the distance X is approximately the same as thickness of the partition wall 5, for instance 0.8-1 .2 times the thickness of the partition wall 5.
