摘要： A split bearing arrangement in a machine housing, particularly a crankshaft journal bearing for piston machines. The split bearing arrangement including a bearing block and a bearing cover that are made of materials of different hardnesses. In order to provide a material anchoring between the bearing cover and the bearing block that can be subjected to high loads and is cost-effective to produce, the bearing arrangement provides the bearing cover, which is made of an iron material, with cutting-edge like projections protruding above its clamping faces and, furthermore, provides grooves in the corresponding clamping faces of the bearing cover and the bearing block. These grooves in an initial mounting of the bearing cover with the required force serve to receive the material of the bearing block that is displaced in the pressing-in process when the projections are pressed into the opposite clamping faces of the bearing block, which is made of a light metal.

摘要： A journal bearing for a high speed surgical drill and/or attachment for rotatably supporting a cutter is made from a polymer of polyimide resin and graphite material and is designed to have a polygon configured bore where there are two point contact of the mating surfaces of the bore walls and cutter's shaft and preferably the bore is square shaped in cross section. This bearing results in a decrease in the envelope size of the support tube and hence, the overall diameter of the surgical instrument at the distal end enhances the line of vision of the cutter to the surgeon when the surgeon is performing surgical procedures. The entrance ends of the intermediate bearings are countersunk to define a ramp to ease the egress of the tool bit shaft for entering the tube of the drill motor or drill attachment during the assembly thereof.

摘要： A core member has a core member side journal portion and a core member bolt hole on both sides of the core member side journal portion and is provided in a separation state from a surface of a casting mold through a cast-off pin including a step portion in a vertical direction in the casting mold. A radius of curvature of the core member side journal portion of the core member is made greater than a radius of curvature of the cap side journal portion of the bearing cap in such a manner that a clearance between the cap side journal portion and the core member side journal portion is larger than a clearance between the core member bolt hole and the cast-off pin. A pouring gate is provided on a side surface of the casting mold to inject a base material along the bonding portion of the bearing cap.

摘要： A crank shaft thrust bearing half includes a semi-cylindrical bearing shell carrying a pair of radially outwardly projecting thrust flanges having outer thrust surfaces. Radial grooves are formed in the thrust face to divide the surface into thrust pads. Each thrust pad has hydrodynamic contours which provide a hydrodynamic wedging action during rotation of the shaft to support high thrust loads. The thrust pad at the trailing end of the flange has an elevated land area spaced about 30° away from the trailing end and includes a long relief area from the land to the end to provide a no contact zone of the flange. Locating the land away from the trailing end and providing the relief zone shifts the peak pressure location away from the end and toward the middle of the bearing to relieve the trailing end from stress. Having radially oriented oil grooves with suitable width enables adequate oil supply and improved hydrodynamic oil film generating capability.

摘要： A bearing metal positioning structure in a split connecting rod with lowered production cost and improved accuracy in positioning the bearing metal. The bearing metal positioning structure includes a pair of bearing metal halves, each of which is formed into a circular arc shape traversing 180 degrees. The pair of bearing metal halves have flat mating planes which abut one another to form a cylindrical bearing metal. A pair of projections are disposed on each of the mating planes at both axial ends so as to project radially outwardly therefrom. Locking grooves to be engaged with the pairs of projections, and additional locking grooves, are integrally die-formed simultaneously with the production of a die-formed body of the split connecting rod.

摘要： The invention relates to a crankshaft bearing for a motor vehicle, in which a crankshaft 1 produced from ADI (austempered ductile iron, DIN EN 1564) is supported on an engine block 2 produced from aluminum without the interposition of other components. There is very little difference between the thermal expansion coefficients between ADI and aluminum materials, ensuring that the bearing operates reliably even when there are fluctuations in temperature.

摘要： The present invention provides a cylinder block which can reduce the vibrations and noises produced from the engine at high temperatures and has a light weight, as well as a method of making such a cylinder block. Specifically, the cylinder block of the present invention comprises a main body (5, 21) of the cylinder block, a bearing (11, 17) attached to the underside of the main body (5, 21), and a crankshaft supported rotatably in a bearing section (13, 25) formed by the underside of the main body (5, 21) and the bearing (11, 17). In this cylinder block, an aluminum alloy layer (33) is formed in the sliding portion of the bearing section (13, 25), the region adjacent to the aluminum alloy layer (33) consists of a composite material (35), and the coefficient of thermal expansion of the composite material (35) is lower than that of the aluminum alloy layer (33) formed in the sliding portion.

摘要： For a machine housing with a split bearing arrangement, particularly journal bearing in piston machines, with a bearing cover clampably arranged via corresponding profiles on a bearing block, it is proposed that a bearing cover having a profile in its clamping face and acting as the tool electrode be used to produce by an electrical discharge machining process a corresponding profile in the clamping face of the bearing block of the machine housing serving as the workpiece electrode in order to achieve an advantageous formation of the profile. After the electrical discharge machining process, the bearing cover is mounted to the bearing block.
