FIELD: engines and pumps.SUBSTANCE: invention may be used in engine building. A cross-head diesel comprises a bed 2 to accommodate a crankshaft 3 and a prop 5 with two outer walls. The prop 5 is arranged on the bed 2 and comprises at least one load-bearing twin-wall housing 6 with crosswise bearing walls. The said housing 6 comprises sliding surfaces for two adjacent cross heads and a cylindrical section arranged at the prop 5 to accommodate the cylinders thereon. The bed 2, prop 5 and cylindrical sections are interconnected by a connecting link 11 extending in the area of the prop 5 in the twin-wall bearing housing 6. The bed 2 incorporates a crosswise bearing one-wall element 12. The bed 2 has at least one bearing seat for the installation of the crankshaft 3. The connecting link 11 is secured in the said bearing seat between the crankshaft 3 lengthwise axis K and the lower end 200 of the bed 2, spaced from the prop 5 in a recess 14, with the help of a fastener 15 that can be removed from the recess 14.EFFECT: decreased stretching forces in the bearing seat radii.11 cl, 5 dwg |
