成される。An example of a shell metal type crosshead pin bearing in a crosshead type diesel engine is shown in FIG. In FIG. 3, 4 is a connecting rod whose lower end is connected to a crankpin (not shown), 3 is a bearing structure material for a crosshead pin bearing formed on the upper part of the connecting rod 4, 1 is a back metal, and 2 is the same. A sliding material made of a copper alloy or the like attached to the backing metal 1. A bearing material 10 is composed of the back metal 1 and the sliding material 2.

から、クロスヘッドピンとクロスヘッドピン軸受とは高
負荷状態で相対すべり運動を行う。The crosshead pin and the crosshead pin bearing are elements for transmitting the force due to the explosion pressure in the combustion chamber to the crankshaft.
Since this crosshead pin bearing is a mechanism that oscillates with respect to the crosshead pin due to the eccentric movement of the crankshaft, the crosshead pin and the crosshead pin bearing perform relative sliding motion in a high load state.

止する必要がある。Since the bearing load accompanying the complicated movement is applied to the crosshead pin bearing in the high load state as described above, the lubricating oil for lubricating the sliding surface 2b through the oil groove 2a of the sliding member 2 is used. It is necessary to prevent the occurrence of wear or seizure between the crosshead pin and the sliding surface 2b by always maintaining the appropriate amount of the oil film.

焼付きの発生をみることが多々あった。However, in the above-mentioned conventional crosshead pin bearing, the backing metal 1 to which the sliding material 2 is attached is fitted to the fitting portion 3a of the bearing structure material 3 which is processed into a semicircular arc shape. Therefore, it is difficult to always maintain an appropriate oil film against a load from a crosshead pin that has a large load and a large load fluctuation. Therefore, wear and seizure of the bearing sliding part should be observed. There were many.

There is provided a method of processing the sliding surface 2b of the above into an elliptical shape. However, according to such a manufacturing method, it is difficult to form an elliptical shape when the thickness of the sliding member 2 is thin, and
The processing accuracy is low and it takes a lot of processing time.
