Definitions
- the invention relates to a balance shaft unit for piston engines, in particular internal combustion engines, for installation in a housing with non-split bearing seats, wherein at least one balance shaft is integral with at least one balance weight.
- Balance shafts are used to balance free mass forces or torques, and second-order inertial forces in inline four-cylinder engines. This requires two balancing shafts, which rotate in opposite directions at twice the crankshaft speed.
- Balance shafts are either housed in a separate housing, which is fixed in the base engine or on the crankshaft bearings. Or their housing is part of the crankcase or the engine block.
- a separate housing which is fixed in the base engine or on the crankshaft bearings. Or their housing is part of the crankcase or the engine block.
- An improved balance shaft should be integral with its balance weights, but still be installed without restriction in terms of their storage in an undivided housing.
- this is achieved in that at least one bearing of the balance shaft is formed by a constriction of the balance shaft as a journal and a housing-fixed split bearing ring whose outer diameter is greater than the outer diameter of the balance weights.
- the balance shaft can be pushed together with their bearing ring or with their bearing rings together in the housing from one side, after previously the parts of the bearing ring were created around the constriction around.
- the balance shaft because in one piece, cheap to manufacture and can be delivered as a ready-to-assemble assembly.
- the main advantage is that the bearing diameter can be kept small thanks to the Einschnü-, whereby smaller circumferential speeds occur in the bearing gap and the friction losses are significantly reduced.
- the bearing ring is divided into two half-rings, the contact surfaces of which have positioning means, preferably at least one bore for a dowel pin.
- the positioning means hold the two half-rings together during insertion into the housing and ensure exact positioning of the half-rings to one another.
- the outer diameter of the bearing ring is dimensioned so that it is smaller than the diameter of the bearing seat in the housing in tiefkaltem state and sits firmly in the latter at normal temperature.
- the balance shaft unit according to the invention can be housed in its own undivided differential housing, or as a tunnel in the engine block or in the crankcase. In the latter case, the advantages of the invention are particularly good advantage.
- Fig. 1 An engine block, are to be installed in the balance shaft units according to the invention
- Fig. 2 A balance shaft unit according to the invention in a built-in
- a balance shaft unit according to the invention may well be an independent housing for a pair of balance shafts, which is fixed in the crankcase to partitions or lids of the crankshaft bearing in a known manner.
- Fig. 2 are of the housing, whichever way it is, only the housing parts forming a bearing seat 8.9 shown. From the bearing seat itself only the circular contour is seen, which corresponds to a cylindrical surface in the interior of the housing parts 8.9 with the diameter 27.
- the two housing parts 8, 9 thus contain the bearing of a balancing shaft 10, which is summarily denoted by 11 and 12 in FIG. 3. 5
- the balancing shaft 10 consists at least of a first cylindrical constriction 13, a second cylindrical constriction 14 and a first counterweight 15 therebetween.
- the constrictions 13, 14 form the bearing surfaces of the balancer shaft 10; whose diameter is substantially smaller than the outer diameter 26 of the at least one balance weight 10 15, which is integral with the balance shaft 10.
- the balancer shaft 10 has two additional balancing weights 16, 17 on the outside of the bearings 11, 12.
- a first bearing ring 20 and a second bearing ring 21 exploded 15 is shown. It consists here of two half rings 20 ', 20 "and 21', 21".
- the outer diameter 28 approximately (see later) corresponds to the inner diameter 27 of the bearing seat. Because the diameter of the constrictions 13, 14 is substantially smaller, the bearing rings 20, 21 can be dimensioned very strongly. You could also call them very thick cups. 20
- the half rings each have contact surfaces 22 with holes 23 into which the pins 25 fit.
- the half rings 20 ', 20' and 21 ', 21' are about the respective constriction
- the balance shaft unit by pressing or, even better and gentler, by hypothermia of the entire balance shaft unit, so the balance shaft 10 with their bearing rings 20,21.
- the excess of the outer diameter 28 of the bearing rings is to be dimensioned so that the inserted bearing rings 20,21 in sit firmly in their camp seats.
- the balance shaft unit can be easily inserted, the tight fit of the bearing rings 20,21 in the bearing seats is made as soon as the balance shaft unit has returned to normal temperature.
