Definitions

  • the invention relates to a bearing shell assembly, a bearing and a semi-circular bearing shell half.
  • the invention relates to a crankshaft main bearing and a mass balance gearbox bearing.
  • the crankshaft of motor vehicle or truck engines is stored in so-called main bearings, via which the oil supply of the connecting rod bearing of the crankshaft takes place.
  • the main bearings are designed with and without collar.
  • the main bearing has an upper bearing shell, which has at least one oil hole and an oil groove extending substantially over the entire inner circumference.
  • the corresponding crankshaft journal has a radial oil bore, through which the oil provided in the upper bearing shell is removed and fed to the connecting rod bearing.
  • the upper bearing shell is designed with and without collar.
  • Such flange bearing shells are known for example from US 4,845,817. As a rule, however, they are so-called built-up flange bearing shells, in which the thrust washers are arranged movably on the bearing shell. Bearing shells with and without collar and with oil groove are also used in so-called mass balancing gearbox bearings.
  • the requirements for such bearings relate, inter alia, the size of the flow cross-section of the oil groove.
  • a wide and deep oil groove is desirable.
  • the depth in terms of stability of the bearing shell limits. Due to the small material thickness at the groove bottom, the bearing shell back may not be completely in the bearing seat. If the oil grooves are too wide, the remaining bearing area of the bearing shell is again too small.
  • Another disadvantage of the conventional bearing shells is that the oil groove must be made by a machining operation, that at least one oil hole must be introduced and that the removed material must be disposed of as waste. During the production of the oil groove as well as during the production of the oil well smallest chips (baubles) are created. These are extremely disturbing in the manufacturing process and must be eliminated by expensive washing operations.
  • the invention preferably relates to bearing shells having an outer diameter of 20 mm to 150 mm.
  • the width Bi of the bearing cup assembly includes the widths of the two bearing shell halves and the width of the oil channel formed between the bearing shell halves. This width Bi is predetermined by the width B 3 of the bearing cup receptacle or bearing bore in the bearing housing. In the case of bearing shell halves with axial bearing parts attached to the edge, the bearing shell halves protrude opposite the bearing bore, so that B 3 ⁇ Bi. In general, B 3 ⁇ B 1 .
  • an oil passage is formed, for the depth according to the invention, the entire thickness of the bearing shell is available. If the widths B 2 of the two bearing shell halves corresponds to the width of the wing portion of conventional individual bearing shells with an oil groove, the oil passage has a larger flow cross-section than the oil groove in the conventional bearing shell. Conversely, with the same flow cross-section as in conventional bearing shells, the wing portion can be increased by a correspondingly greater width of the bearing shell half.
  • the width of the oil passage and thus the flow cross section can be selected by the user himself by determining the distance of the bearing shell halves by the choice of the width B 2 to each other.
  • Each bearing shell half preferably has an axial bearing part at each edge. While in conventional flange bearing shells the impbundment between the two Axiallager sculpture is fixed, this can now be chosen freely. The bearing shell halves are thus used variably.
  • both bearing shell halves are identical.
  • the production can be considerably simplified.
  • the oil passage extends over the entire circumferential length of the bearing shell halves.
  • the two bearing shell halves do not touch.
  • a particular use of at least two semicircular bearing shell halves is provided for oil-lubricated bearings, especially in vehicle engines.
  • the oil-lubricated bearing having a first and a second bearing shell, which abut each other at their partial surfaces, is characterized in that at least one of the two bearing shells is divided into two and consists of two semicircular bearing shell halves, which are arranged in the axial direction of the bearing spaced from each other, wherein between the Bearing shell halves a circumferentially extending oil passage is formed.
  • the crankshaft main bearing with a bearing housing having a bearing bore of width B 3 and a bearing arrangement of the width Bi used in the bearing housing of an upper shell and a lower shell, wherein the bearing housing has at least one oil supply to the upper shell, characterized in that the upper shell is divided into two parts and two semicircular bearing shell halves is arranged, which are arranged spaced from each other in the axial direction of the bearing, wherein between the bearing shell halves, a circumferentially extending oil passage is formed, in which the oil supply opens.
  • the mass balancing transmission bearing with a bearing housing having a bearing bore of width B 3 and an upper shell inserted in the bearing housing and a lower shell, wherein the bearing housing has at least one oil supply to the lower shell, characterized in that the lower shell is divided into two and consists of two semicircular bearing shell halves , which are spaced apart in the axial direction of the bearing, wherein between the bearing shell halves, a circumferentially extending oil passage is formed, in which the oil supply opens.
  • the bearing shell halves of the crankshaft main bearing and the mass balance gear bearing can be provided with or without thrust bearing parts.
  • a semi-circular bearing shell half width B 2 with outer diameter D and partial surfaces is characterized in that the bearing shell half with a second half-circular bearing shell half width B 2 to a bearing shell arrangement of the width Bi for a bearing is assembled, the two bearing shell halves in the axial direction next to each other are arranged, which is located between the bearing shell halves extending in the circumferential direction of the bearing shell halves oil passage, and that for the ratio V of bearing shell outer diameter D in mm to width B 2 in mm of the bearing shell half applies: 2.5 ⁇ V ⁇ 6 for 20 ⁇ D ⁇ 24 2.4 ⁇ V ⁇ 10 for 24 ⁇ D ⁇ 40
  • the semi-circular bearing shell half has at least one retaining cam in the partial surface, which projects from the outer circumference of the bearing shell half.
  • a retaining cam is provided in each partial area. The provision of at least one retaining cam in each partial area has the advantage that a high level of alignment accuracy is ensured and an axial wandering in the bearing seat is prevented.
  • the semi-circular bearing shell half is characterized by an axial bearing part which is arranged on an edge of the bearing shell half.
  • the bearing shell halves are characterized by a lesser skew of the partial surfaces ( ⁇ 0.03 mm) with respect to the apex area.
  • FIG. 2 a perspective view of a bearing according to a further embodiment, 3 shows a section through the bearing assembly of Figure 2 in the installed state, and
  • FIG. 4 shows a bearing shell half according to a further embodiment.
  • FIG. 1 shows a bearing 1 with an upper shell 4 and a lower shell 3. While the lower shell 3 is a one-piece smooth shell, the upper shell 4 is divided into two and consists of a bearing shell assembly 10 of width B 1 with two semicircular bearing shell halves 11 of width B 2 , which are spaced from each other, so that between the two bearing shell halves 11, a gap 12th is formed, which forms an oil passage 14 in the installed state together with the bearing housing. This will be explained in connection with FIG.
  • the bearing shell assembly 10 is formed from two mutually spaced bearing shell halves 11 ', each having an axial bearing 13 at its outer edge.
  • Such bearings are used inter alia as a crankshaft main bearing 2.
  • the lower shell 3 consists of a one-piece smooth shell.
  • FIG. 3 shows a partial section through the bearing 1 shown in FIG. 2, the section extending through the bearing shell arrangement 10.
  • the bearing housing 20 is located, which has an oil feed 21 in the center. This oil supply 21 opens into the intermediate space 12 between the two bearing shell halves 11 ', which thus forms an oil passage 14.
  • the entire bearing shell thickness LD is available for the oil passage 14.
  • FIG. 3 is representative of a crankshaft main bearing 2, wherein the bearing housing 20 is formed by a connecting rod.
  • the bearing receptacle 22 is in this example the large connecting rod eye.
  • Figure 3 is also representative of a
  • Mass balance gear bearing in which case the lower shell is formed by two axially adjacent bearing shell halves.
  • FIG. 4 shows a perspective view of a bearing shell half with an axial bearing part 13.
  • Each partial surface 16 of the semicircular bearing shell half 11 ' has a retaining cam 15, which protrudes with respect to the outer peripheral surface.
