Abstract:
A substrate (20) having one or more shaped effusion cooling holes formed therein is disclosed. Each shaped cooling hole has a bore (53) angled relative to an exit surface (37) of the combustor liner. One end of the bore is an inlet (13) formed in an inlet surface (36) of the combustor liner. The other end of the bore is an outlet (11) formed in the exit surface (37) of the combustor liner. The outlet has a shaped portion that expands in only one dimension. Also disclosed are methods for making the shaped cooling holes.
Abstract:
The invention relates to a method for producing a piston of an internal combustion engine, wherein the piston has a combustion bowl comprising a combustion bowl rim, and the combustion bowl rim is hardened by being remelted in a first step by means of an inductive energy supply and in a further step by means of a laser beam. According to the invention, the laser beam is deflected during a rotary, progressive motion relative to the piston.
Abstract:
Die vorliegende Erfindung betrifft ein Ramm- und Bohrgerät mit einem Mäkler, einer Umlenkvorrichtung zum Umlenken eines Seils, welche am Kopf des Mäklers verschwenkbar zwischen zumindest einer Transportposition und zumindest einer Arbeitsposition angelenkt ist, wobei die Umlenkvorrichtung um eine schräg auf der Erstreckungsachse des Mäklers stehende Achse drehbar ist.
Abstract:
The invention relates to a method for providing a component of a large machine, especially a piston head or an outlet valve head of a large two-stroke diesel engine, with a protective coating (4) which is applied to the corresponding surface (2 or 14) by means of surfacing. According to the ivnention, the method can be carried out in an economical and careful manner due to the fact that the large machine component provided with the protective coating (4) is cooled during the surfacing process.
Abstract:
A piston main body (13) in a piston assembly (10A) of a fluid pressure cylinder (11) has a first piston member (40) and a second piston member (42) composed of a plate-shaped member. The first piston member (40) and the second piston member (42) are joined in a state overlapping in the axial direction of a piston rod (15). The second piston member (42) is not provided with a hole that passes through in the plate thickness direction.
