摘要： A method for mechanically roughening a cylindrical surface of a workpiece, e.g. the piston-bearing surface of a cylinder sleeve in a cylinder crankcase, by producing a defined microstructure of mutually crossing grooves, and by a groove forming tool, operating with or without material removal. A method in which in a first operation, a groove-forming tool is moved axially along the workpiece surface in such a way that at least one axial groove is machined into the workpiece surface; and in a second operation, following the first operation, the groove forming tool is rotated about the cylinder axis by a predefined rotational angle in the axial position reached in the first operation, whereby at least one circumferential groove crossing the axial groove is machined into the workpiece surface; and in a third operation following the second operation, the groove-forming tool is drawn back axially along the workpiece surface.

摘要： A piston for an engine includes a skirt part, and a resin coating film and a recess formed on a surface of the skirt part. A plurality of the resin coating films are discretely arranged in spots on the surface of the skirt part, and a mesh-like groove is formed by the recess provided between the resin coating films. The recess formed on the skirt part between the resin coating films adjacent to each other in a piston circumference direction is set to be adjacent to another resin coating film in a piston moving direction. An end part of the resin coating film in the piston moving direction is formed in a concave shape when seen in a piston radius direction.

The piston head has at least one groove which runs in a circumferential direction suitable for receiving a piston ring, and the piston shaft has a pin boss and, at its outer circumference, a guide surface which is suitable for guiding the piston along a cylinder inner wall. An outer diameter of the piston neck is smaller than an outer diameter of the piston head and/or of the piston shaft, and the length of the piston neck approximately corresponds to the travel of the piston in the installed state.

摘要： A sliding element 20, such as a bushing or bearing, includes a sintered powder metal base 24 deposited on a steel backing 22. The base 24 includes a tin, bismuth, first hard particles 40, such as Fe3P and MoSi2, and a balance of copper. In one embodiment, a tin overplate 26 is applied to the base 24. A nickel barrier layer 42 can be disposed between the base 24 and the tin overplate 26, and a tin-nickel intermediate layer 44 between the nickel bather layer 42 and the tin overplate 26. In another embodiment, the sliding element 20 includes either a sputter coating 30 of aluminum or a polymer coating 28 disposed directly on the base 24. The polymer coating 28 includes second hard particles 48, such as Fe2O3. The polymer coating 28 together with the base 24 provides exceptional wear resistance over time.

摘要： The present invention utilizes rolling elements, such as balls or rollers acting as bearings carried in openings in the skirt or equivalent portion of a piston, to engage the cylinder walls and replace the sliding bearings of the skirt with the roller elements in the skirt. The rolling elements then absorb all or some of the thrust loads conventionally absorbed by the skirt walls sliding along surfaces of an associated cylinder and thereby reduce the friction forces developed by the reciprocating action of the piston skirt.
