    摘要: The invention relates to gudgeon pin bushes which find application in highly-stressed engines, with the problem of a tendency to pit, in particular in the middle regions (with relation to the radial axis of the bush), on starting the motor. According to the invention, the problem can be avoided whereby the friction surfaces of a gudgeon pin bush, at least in the high loading region, have the following parameters measured over the bush cross-section in the axial direction: the support percentage is a minimum of 99.0% to a depth of at most 1.800 m, the depth of the roughness core profile is at most 0.30 m, the proportion of the material Mr1 of the roughness core profile is at most 8%. The gudgeon pin bush can be obtained by finishing the bearing surface of the gudgeon pin bush using a surface machining method.

    摘要: A method and an apparatus for testing the adhesive strength of overlays attached to the inside of plain bearing bushings. The method is characterized in specifying clearance between the plain bearing bushing tested and a rotating or oscillating pin extending through the bushing. Next, feeding a liquid medium into the gap between the bushing and the pin and oscillating the plain bearing bushing and pin relative to one another perpendicularly to the bushing axis for a given period and examining the bushing after the load test. The corresponding apparatus comprises a pin mounted rotatably in a pin receptacle and on which there is arranged a first drive mechanism. In addition, a bushing receptacle is provided, in which the plain bearing bushing is fitted, wherein the pin is mounted with predetermined clearance in the bushing. The apparatus additionally comprises a mechanism for bringing about oscillating relative movement of bushing receptacle and pin receptacle.

    摘要: A multi-stage regulating valve is provided with a cylinder and an adjusting piston guided inside it to which a regulating pressure can be applied from one side and a return force from the other. Depending on the regulating pressure, the piston keeps at least one outlet aperture in the cylinder wall closed or partly or fully opens it and thus closes off a connection to the side of the piston to which the regulating pressure is applied or partly or fully opens it via the outlet aperture. To provide a multistage regulating valve which can alter the regulating characteristics over a wide range depending on the position of the piston even without the use of several return components, the piston consists of at least two partial pistons to which the regulating pressure can be applied, where the force of the return component can be applied to a first partial piston, whereby a follower interconnects the partial pistons in such a way that a return force is exerted on the second partial piston or other partial pistons via the first partial piston and the follower. The cylinder has at least one stop for the second or other partial pistons limiting the movement of the second or other partial pistons under the effect of the regulating pressure and against the action of the return component. The first partial piston is unaffected by the stop and remains movable against the return component if the regulating pressure increases further.
