Definitions
- the invention relates to a crankcase for an internal combustion engine with V-shaped cylinders, which is divided into two parts along a parting plane passing through the axis of the crankshaft, the bearing screws running on both sides of the crankshaft bearings, running perpendicular to the parting plane, and cylindrical fitting pieces are connected to each other, which engage in a fitting bore provided between the two housing parts.
- crankshaft bearings consist of comparatively thin bearing shells that are inserted in the bearing bores between the two crankcase parts. This means that the two parts of the crankcase cannot be centered over the crankshaft bearings.
- the invention is therefore based on the object to design a crankcase of the type described for an internal combustion engine with V-shaped cylinders so that a precisely centering and load-bearing connection of the two crankcase parts can be ensured with little manufacturing effort.
- the invention solves this problem in that the adapters running parallel to the axis of the crankshaft lie in the parting plane and are penetrated by a bearing screw each.
- the adapter bores for these adapters can be drilled together with the bearing bores for the crankshaft bearings, which combines simple design conditions with high accuracy. Since the centering and the load transfer parallel to the division level is achieved by the separate pieces of the bearing bolts, there is no need for fitting holes for the bearing bolts, so that the mounting holes for the bearing bolts can be created without particular accuracy. Despite the A separate, less protruding construction is ensured by the fitting pieces which are separate because the fitting pieces are penetrated by the bearing screws. Thus, the bearing screws passing through the adapters fix the adapters in the axial direction, so that no additional construction measures are required for this.
- crankcase according to the invention for an internal combustion engine with V-shaped cylinders is shown in a schematic, partially broken front view.
- crankcase 1 shown has two parts 2 and 3, the division plane of which is designated by 4.
- the upper part 3 of the crankcase 1 forms the receptacles 5 for the cylinder liners of the V-shaped cylinders.
- the crankshaft 6 is mounted between the crankcase parts 2 and 3 in crankshaft bearings 7, which consist of comparatively thin bearing shells inserted in bearing bores 8 between parts 2 and 3. Laterally next to the bearing bores 8, the crankcase parts 2 and 3 are connected to one another by bearing screws 9 which pass through the crankcase part 2 in through bores 10 and engage in threaded bores 11 of the crankcase part 3.
- cylindrical fitting pieces 12 are provided, which run parallel to the axis of the crankshaft 6 and lie in the parting plane 4. These adapters 12 engage in adapter bores 13 between the crankcase parts 2 and 3, so that via the adapters 12 not only a centering of the crankcase parts 2 and 3 but also a transfer of forces parallel to the parting plane 4 is possible. Since the fitting holes 13 can be drilled together with the bearing bores 8, precise alignment of the crankcase parts 2 and 3 with respect to the axis of the crankshaft 6 can be ensured with simple means, regardless of the accuracy of the arrangement of the bearing screws 9.
- the adapters 12 have through holes 14 for the associated bearing screws 9, so that the adapters 12 are axially fixed via the bearing screws 9 passing through them. In addition, a compact construction is ensured because no additional space is required laterally next to the bearing screws 9 due to the separate adapters 12. Since the adapters 12 have been assigned to the respective outer bearing screws 9, the inner bearing screws 9 can be provided near the bearing bores 8.
