Previously, for the casting of plain bearing shells operating under medium load conditions, for example in slow running marine engines, ball mills. , gas compressors, railroad cars, and tin alloys containing 80 to 90% tin, 4 to 13% antimony, 5 to 10% copper and lead tin alloys containing 2 to 20% tin, liOi up to 16% antimony, up to 3% copper or. arsenic, a minimum of 58% lead. The current designs of these devices are more demanding, and therefore the requirements for bearing alloys have also increased. The applied tin and lead-tin alloys turn out to be insufficient, and because of the components of these alloys, they are relatively expensive. Alloys suitable for higher requirements should be able to transfer unit pressures of 12 to 18 MPa for a long time at a temperature of 353 to 413 K, corresponding to the operating temperature range of ice-cadmium 4.1 to 18.0%, nickel plus cobalt 0.10 to 1.5% and a minimum of 77.5% lead. As reinforcing elements, the content of which has been determined by weight, there are: These conditions are met by the alloy according to of the invention, consisting of a plastic matrix and reinforcing elements, at least one of which strengthens the matrix, containing by weight: 10 15 20 25 30 calcium manganese bar silver copper aluminum scand tellurium yttrium arsenic magnesium vanadium titanium zinc sodium silicon zircon chromium beryllium molybdenum oxygen nitrogen boron 0.001 (M01 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 0.001 to 1.0% to 1.0% to 1.0% to 1.0% to 1.0% to 1.0 % to 2.5% to 2.5% to a. 5% up to 2.5% up to 2.5% up to 0.5% up to 0 ^ 6% up to 0.5% up to 1.0% up to 1.0% up to 0-2 and 5% up to 0.25% up to 0-25% up to 0 25% 0 / MM) 1 to 0.25% 0.0001 to 26% 0.0001 to 0.25%, 122 601 122 601 3 where the sum of the reinforcing elements used for the alloy does not exceed the weight of 3. 0% of the alloy. The alloy based on the invention, reinforced with the appropriate reinforcing elements, after pouring in the bearing, is heat treated at a temperature of up to 458 K and plastic processed at a deformation degree of 10 to 60%. The elastic properties of the alloy are then 35 to 65% higher. from those obtained in the previously used tin alloys. The drop in elastic properties at the temperature of 410 * -K is very mild, not exceeding 415% of the temperature at the ambient temperature, which proves that the alloy is heat stable. The advantage of the alloy is also the extremely low coefficient of friction of the dry material * as well as the corrosion resistance of polyoxy and felJcMil compared to tin alloys. The alloy according to the invention will be characterized in more detail on the examples in which, in addition to the alloy composition, the following is also given mechanical properties obtained from the performed heats: - tensile strength Rm, - yield strength Re, - notched impact strength Kv, - hardness HB 2.5 / 15.625 / 60 s. 1. 2. 4.Cd Ni A $ Pb Cd Co Ni Zr Pb Cd Cu Co Zr Ba Pb Cd Co Ni Pb 17.85% 1.23% 1.17% balance 17.92% 0.87% 0.10% 0.062% balance 15.65% 0.98% ai2P / about 0.055% 0.21% rest 15i, 63%. 0.82% 0.1 li2% rest (Rm Re Ky HB iRm Re Kjv HB 'Rm He KJv HB Rm Re Kv HB 96.5 MPa 62.3 MPa 111.3 J / cm2 130.6 106 MPa 73.3 MPa 21.3 J / cm2 fl | 7.8 116 MPa 82 ^.6 MPa 10.2 J / cm2 20.2 91.5 MPa 63.6 MPa 22.8 J / cm2 25.2 5, Cd Co Ni Ba Pb 17.88% 0.96% 0.14% 0.26% rest (Rm Re Kv HB 118 MPa 87.8 MPa 14.6 J / cm2 3 (1.3 10 15 20 The mechanical properties shown in the examples are These alloys allow for the application of heat treatment at a temperature of 423 K and plastic working at 20% deformation to obtain a unit pressure of about 15 MPa.
