Definitions

  • the present invention relates to a crank-case for an internal combustion engine in particular with one or two longitudinal rows of built-in cylinders as well as to the various applications and uses resulting therefrom and to the engines and machines fitted therewith.
  • crank-cases for internal combustion engines with a plurality of built-in bylinders arranged in particular either in line or in two longitudinal rows according to a V-shaped arrangement, of the type forming a possibly ribbed hollow box of combined construction that is forming an assembly composed of cast or forged elements and of metal sheets andv like rolled products connected together by welding.
  • Such a structure often exhibits a configuration with pillars or legs comprising in particular transverse, vertical, spaced, intermediate and end partitions forming supporting webs for the crank-shaft bearings and welded for this purpose on forged yokes or the like, respectively, constituting the bearing cages.
  • each supporting plate has its direction corresponding to its largest dimension disposed transversely of the crank-case with a roof-like configuration forming an upward projecting dihedron having its edge directed longitudinally of the crankcase substantially in the longitudinal vertical centre plane thereof.
  • Each supporting plate is then provided with a pair of transverse openings for example longitudinally offset or shifted with respect to each other and located in the faces, respectively, on either side of said central edge whereas in the case of an engine with inline cylinders, each plate is substantially flat and horizontal and comprises one single aforesaid opening.
  • the assembly of the transverse partitions and of the supporting plates is welded on each side, respectively, on longitudinal metal sheets forming a pair of at least approximately vertical opposite side walls or faces of the crank-case between and to which are welded said transverse partitions and supporting plates.
  • a tablet-like metal sheet which is substantially flat and horizontal in the case of an engine with in-line cylinders or folded according to a roof-like configuration in the case of an engine with V-shaped cylinders is welded to the corresponding ends of the transverse partitions and of the longitudinal side walls.
  • This metal sheet is formed with parallel circular openings which are coaxial with those of said supporting plates, which openings are adapted to accommodate the cylinder water jackets.
  • the transverse partitions and longitudinal side walls thus extend substantially continuously throughout the height of the crank-case above and below the intervening cast supporting plates.
  • the longitudinal walls extend substantially throughout the length of the crank-case and the transverse partitions also extend substantially continuously over the whole width of the crank-case.
  • transverse partitions are substantially flat in the case of an engine having inline cylinders whereas they are offset or shifted longitudinally with respect to each other by being bent twice in opposite directions along vertical folds in the case of an engine with V-shaped cylinders to make allowance for the longitudinal offset of staggering of the cylinders from one row to the other when such an offset is present.
  • the transverse partitions are in addition braced above the sup porting plates by longitudinal, vertical metal-sheet members substantially aligned above the central crest or ridge of the cast supporting plates extending throughout the height available between said supporting plates and the upper tablet-like metal sheet to form a central vertical longitudinal partition welded to the transverse partitions, to the supporting plates and to the upper tablet-like metal sheet.
  • the assemblies are generally carried out by fillet welding with seams or the like.
  • the fillet welding step is relatively difficult to carry out at least on some portions of the crank-case owing to the fact that the joints to be welded are not very accessible.
  • Such a fillet welded construction also exhibits a relatively large number of welded joints which is not appropriate in view of the pressure of concentrated residual stresses and from the standpoint of the cost price.
  • the main object of the invention is to remove said drawbacks and difficulties by providing a crank-case composed of a relatively reduced number of parts and elements assembled by welding.
  • the crankcase according to the invention is characterized in that said, supporting structure is a single supporting plate consisting of one single integral for example cast or rolled part forming a single continuous main beam made in one piece of material and receiving the anchoring of the cylinder tie-bolts whereas said transverse partitions and longitudinal walls consist each one of a bottom portion and of a top portion substantially in extension of each other and which are welded to said supporting plate below and above the latter, respectively, while being separated thereby, said upper tablet-like plate or metal sheet being welded to said top portions.
  • each aforesaid transverse partition consists of a pair of bracing'elements fillet welded at a preferably substantially right angle to said longitudinal partition on either side thereof and to each aforesaid side wall between the latter and said longitudinal partition.
  • said supporting plate comprises on each one of its opposite respective lower and upper faces, at least approximately vertical projecting ribs or ridges forming scarfs of material integrally cast for buttwelded assembly with said partitions and walls.
  • FIG. 1 shows an elevational view in cross-section taken upon the broken line I-l of FIG. 2, of a crankcase of an internal combustion engine in particular of the Diesel type with a pair of rows of radially arranged V-shaped cylinders with mounted crank-shaft and bearings
  • FIG. 2 is a fragmentary view in cross-section taken upon the broken line II-II of FIG. 1 showing in particular the top of the integral supporting plate made from cast steel together with the top portions of the partitions and walls
  • FIG. 3 is a fragmentary view drawn to a larger scale in horizontal section taken upon the line III-III of FIG. I, particularly showing the structure of the bottom portion of one transverse partition
  • FIG. 4 is a fragmentary view at an enlarged scale in partial section taken upon the line IVIV of FIG.
  • FIG. 5 is a enlarged view of the encircled detail V of FIG. 1 showing one portion of the central region of the top of the supporting plate integrally made from cast steel;
  • FIG. 6 is a view similar to the preceding one and showing the encircled detail VI of FIG. 1 in the lateral edge region of the supporting plate made in one piece from cast steel;
  • FIG. 7 shows a separate top view of said supporting plate according to a form of embodiment carried out by casting in two cast parts connected together by a transverse weld
  • FIG. 8 is an end side view, seen from the left-hand side, of the supporting plate shown on FIG. 7
  • FIG. 9 is an enlarged fragmentary view in crosssection taken upon the line IX-lX of FIG. 7 of the area assembled by welding and
  • FIG. 10 is an enlarged fragmentary cross-sectional view of the upper portion of an engine crank-case showing an alternative embodiment of the supporting plate made in two parts connected together by a central longitudinal weld.
  • crank-case shown therein is intended for use with a Diesel engine with V-shaped cylinders which are for example longitudinally offset or shifted with respect to each other from one row to the other and the longitudinal central planes of which passing through the cylinder axes of both cylinder rows, respectively, define for example therebetween a 45 dihedral angle.
  • the base plate forming in particular the oil sump has not been shown.
  • This crank case essentially comprises the integral supporting plate made in one piece from for example cast or rolled steel and generally denoted by the reference numeral 1 and extending continuously substantially throughout the length of the crank-case.
  • This supporting plate assumes substantially the shape of a roof defining a dihedral angle the top edge or crest line of which is located in the central longitudinal vertical plane of the crank-case.
  • This supporting plate comprises in each face of its dihedron openings 2 adapted to accommodate the lower portions of the cylinder liners and the axes of which are mutually offset or shifted with respect to each other in the longitudinal direction from one cylinder row to the other according to FIG. 2 which particularly shows the end portion of the crank-case located on the side opposite to the timing system or coupling.
  • the supporting plate On its top face the supporting plate comprises blind tapped holes 3 (FIGS.
  • the supporting plate 1 comprises projecting connecting ridges or ribs for buttwelded assembly edge-to-edge of the supporting plate with other structural elements of the crank-case and directly integrally cast in one piece with said supporting plate. These connecting ridges or welding assembly scarfs are in the shape of continuous ribs.
  • the bottom face or the supporting plate 1 thus exhibits a pair of continuous parallel longitudinal substantially vertical ribs 8 extending along each one of both longitudinal opposite edges, respectively, of the supporting plate and transverse, spaced, substantially parallel and vertical ribs 9 extending continuously throughout the width of the supporting plate between the longitudinal ribs 8 and separating transverse pairs of openings 2, respectively. All of these ribs are substantially flat and straight so that the transverse ribs 9 are oblique or inclined with respect to the longitudinal direction of the crank-case for making allowance for the possible mutual offset or staggering of the openings 2 in the longitudinal directionof a longitudinal row of openings with respect to each other.
  • the top face of the supporting plate 1 comprises a pair of continuous longitudinal lateral substantially straight ribs 10 extending over the whole length of the crank case, respectively, along both opposite longitudinal edges thereof while being directed obliquely upwards so as to diverge sidewise outwards.
  • the top face of the supporting plate 1 comprises in addition on the one hand a longitudinal, central, substantially vertical, straight rib 11 extending continuously along the longitudinal, central crest line of the supporting plate and substantially parallel'and vertical, spaced, straight, transverse ribs 12 extending on each face of the dihedron formed by the supporting plate, respectively, throughout the width thereof between one longitudinal side rib 10 and the cental longitudinal rib 11 substantially at right angles thereto so as to separate the successive openings 2, respectively, in each face, whereby these transverse ribs 12 are longitudinally offset from one face to the other according to the corresponding offsets of the openings 2 of these respective faces.
  • continuous longitudinal ribs 10 and 11 of the top face of the supporting plate are respectively butt-welded three substantially flat continuous longitudinal metal sheets extending substantially through the length of the crank-case and comprising a pair of lateral metal sheets 13 forming sidewalls or faces of the the adjacent transverse partition to form a box adapted to accommodate the distribution or timing system.
  • transverse ribs 12 of the top face of the supporting plate 1 are respectively butt-welded substantially flat and vertical transverse metal sheets 15 forming upper transverse partitions, respectively, aligned with their associated ribs in extension thereof, so that they are also offset in the longitudinal direction from one face to the other of the supporting plate 1 according to FIG. 2.
  • These metal sheets of the upper transverse partitions 15 are respectively fillet welded onto the longitudinal lateral and central metal sheets 13 and 14.
  • the longitudinal metal sheets 13 and 14 are limited by a single transverse metal sheet 16 twice bent in opposite directions and extending over the whole width of the crank-case and onto which the longitudinal metal sheets 13 and 14 are secured by fillet welds (FIG. 2). As shown on FlG.
  • each end of the crankcase is limited or terminated by a substantially flat and vertical end wall metal sheet 17.
  • this end metal sheet is spaced to a larger extent from lel relation thereto and forming an upper tablet.
  • round openings 19 are provided in each face of the dihedron formed by the metal sheet 18 in each face of the dihedron formed by the metal sheet 18 corresponding to the openings 2, respectively, of the supporting plate while being arranged in parallel and coaxial relation thereto to accommodate the water jackets 5 of the cylinders.
  • the upper portion of the crank-case located above the supporting plate 1 is thus divided into adjacent compartments each one assigned to one cylinder of the engme.
  • each transverse rib 9 of the bottom face of the supporting plate 1 is butt-welded a transverse partition made from cast steel 21 and assembled in edge-toedge relationship in alignment with the associated rib 9 in extension thereof.
  • Each transverse partition 21 extends over the whole width of the crank-case between the lateral longitudinal metal sheets 20 and is fillet welded onto the latter.
  • At least each intermediate transverse partition 21 comprises a substantially flat solid web 22 and a central recess 23 at least approximatively in the shape of an inverted U opening downwards and defined by a thickened bead-like or bulb-like portion 24 forming a yoke-shaped crank-shaft bearing cage integrally cast in one piece with the web 22. As shown in particular by FIG.
  • the bearing cage or yoke 24 has a substantially flat and vertical configuration directed at right angles to the horizontal crank-shaft axis 25 hence to the longitudinal side walls 20 of the crankcase whereas the web 22 is disposed obliquely with respect to the plane of the bearing cage 24 hence with respect to the crank-shaft axis 25 so as to follow the obliqueness of the associated transverse rib 9 of the supporting plate between two adjacent,transverse,- successive pairs of cylinders to match the possible longitudinal offset of the latter from one cylinder row to the other.
  • This offers the advantage of removing the double folding in opposite directions of the transverse partitions of the crank-cases known from the prior state of the art.
  • the transverse partitions 21 therefore define together with the longitudinal side walls 20 successive adjacent compartments opening downwards and corresponding each one to one transverse pair of cylinders.
  • Such a configuration enables to mount the crank-shaft 26 within the bearing cage 24 so that it may be easily removable from below.
  • Through each longitudinal lateral metal sheet 20 extends at least one for example substantially circular inspection hole 27 opening into one aforesaid compartment and enabling the inspection and disassembling of the pivotal connections, couplings and connecting-rod bearings. These holes are normally closed by removable doors or covers not shown.
  • crank-shaft 26 which in this example is removable from the bottom, is mounted with its journals in suitable bearing bushes and held in the corresponding bearing yoke 24 by means of a removable bearing body portion 28 detachable from the bottom which is secured by a pair of tiebolts 29 screw-threaded within suitable tapped holes of the bearing cage 24 and receiving corresponding nuts 30 at their respective free lower ends.
  • Each bearing body portion 28 is moreover held laterally on each side by a transverse substantially horizontal screw 31 extending through a smooth hole provided in a corresponding cast boss of the partition 21 for being screwthreaded into a tapped blind hole of the bearing body portion 28.
  • Two longitudinal substantially horizontal side base flanges 32 are welded to the bottom of the longitudinal walls and to the transverse partitions 21, respectively, on each side. These flanges extend substantially continuously over the whole length of the crank-case and serve to secure the crank-case onto the base plate, a pedastal or like supporting platform known per se.
  • the exemplary form of embodiment shown is concerned with an engine with V-shaped cylinders which are longitudinally offset from one row to the other the invention is also applicable to the case where the cylinders are not offset or shifted that is wherein the axes of two cylinders of a transverse pair of cylinders are meeeting in a same plane extending at right angles to the crank-shaft of the engine. In this latter case the web of each transverse partition is no longer oblique but also perpendicular to the engine crank-shaft.
  • the stand-by ridges for butt-welding onto the supporting plate could possibly be omitted and the buttwelding could be replaced by a fillet welding in this case the cast supporting plate could be replaced by a supporting plate made from sheet metal or a like rolled product.
  • crank-shaft could also be mounted so as to be removable from above while still using a bearing body portion removable from below.
  • the bearing yoke within the transverse partition is more deeply recessed upwards to allow the accommodation of an upper bearing cap removable from above and clamped against the bearing body portion by a set screw engaging the yoke and selectively adjustable to the desired clamping pressure by means of a hydraulic actuator incorporated into the bearing cap.
  • the supporting plate 1 will be substantially flat and horizontal and the transverse partitions will have their webs extending substantially at rights angles to the crank-shaft axis.
