Definitions
- Machine housing with a split bearing arrangement in particular plain bearings in reciprocating piston machines
- the invention relates to a machine housing with a split bearing arrangement, in particular plain bearings in reciprocating piston machines, with a bearing cover arranged to be braced on a bearing bracket, both of which are in a form-fitting connection with one another in their clamping surfaces at least in regions via corresponding profiles.
- the invention has for its object to show a measure for a more favorable profile training for a generic machine housing.
- a form-fitting, precise profile in the bearing bracket and bearing cap can be formed perfectly in the case of identical materials as well as in the case of dissimilar materials with bearing caps formed in particular from an iron material.
- an erosion-rough surface with a roughness Ra of approximately 50-300 ⁇ m is produced, with hard free-standing deposits (crystals) in the clamping surfaces made of similar materials of the bearing bracket and the bearing cover, corresponding recesses in the respective counter surface have a tooth surface-like gearing profile.
- FIG. 1 shows a bearing arrangement with a bearing cover shown separately from the bearing chair, with a profile, the corresponding profile of which
- EDM is to be generated in the clamping surface of the bearing chair
- Figure 2 is a profile with pyramid-like tips deviating from the profile with cutting-like projections according to Figure 1.
- a machine housing 1 with a split bearing arrangement 2, preferably a crankshaft sliding bearing 3 in a reciprocating piston internal combustion engine, not shown, comprises a bearing block 4 with a bearing cover 5 arranged so that it can be clamped, both of which have clamping surfaces 6, 7, at least in regions, via corresponding profiles 8, 8 'are in a positive connection with each other.
- Cutting-like projections 9 or pyramid-like tips 10 are preferably provided as profiles 8 over triangular or square bases.
- a machine housing 1 in particular made of an aluminum alloy, for a V-type internal combustion engine, it is preferably proposed that the projections 9 or tips 10 are machined on a bearing cover 5 made of iron material and that the projections 9 have a cutting edge angle ⁇ or the tips 10 have a cone angle ⁇ of 50 ° - 10 ° each with a cutting edge or tip height "H" of 0.25 - 1.5 mm, the cutting edge distance "A" of the projections 9 or the distance "A” of the tips 10 is between 0.5 - 3.0 mm.
- this aforementioned goal is also achieved in that in the clamping surfaces of the bearing cover 5 and the bearing block 4, which are assigned to each other and are spaced apart in accordance with an electroerosive machining process, an erosion-rough surface with a roughness Ra of approximately 50-300 ⁇ m is produced, by means of With hard, free or protruding inclusions (crystals) in the clamping surfaces made of similar materials (aluminum alloys) formed by bearing bracket 4 and bearing cover 5 corresponding depressions in the respective counter surface 6, 7 a fracture surface-like toothing profile is achieved (not shown).
- This profile formation is preferably used for a crankshaft bearing frame of a V-engine or internal combustion engine, wherein the machine housing 1 and the bearing frame (not shown) are each made of an aluminum alloy.
- the aluminum alloys used are in particular those in which relatively large and hard crystals are embedded.
- the invention relates to the use of an electroerosive machining method for the formation of positive clamping surfaces between the bearing cover and the bearing chair a split bearing arrangement aligned in a machine housing, the use of the bearing cover as a tool electrode per se can be derived from DE-A 44 36 803, in which an externally toothed wheel is known as an electrode for producing an internally toothed workpiece by means of spark erosion.
