摘要： A bearing with an oil film thickness measuring device in which sensor portions at distal ends of four common optical fibers are connected to sensor mounting portions formed at four positions in an axial direction of a bearing body. A lubricating oil containing a fluorescent agent is supplied to a sliding surface of the bearing body. A laser beam generated from a laser beam generator is branched into four beams, which are applied to an oil film on a sliding surface through each of sensor portions. Fluorescence generated by the fluorescent agent in the oil film, passing through a return-route optical fiber, is introduced into a photomultiplier tube, and is detected. Since the fluorescence intensity detected by the photomultiplier tube is proportional to the thickness of oil film, the absolute value of oil film thickness can be measured. In this case, the oil film thickness can be measured at four positions.

摘要： A sliding bearing comprises a back metal and a bearing alloy layer formed thereon, the thickness of the back metal gradually decreasing from the middle portion toward each axial end portion, and the thickness of the bearing alloy layer being increased at each axial end portion. The bearing alloy layer has a Young's modulus smaller than that of the back metal of steel plate and hence it is elastically deformed with greater ease, and therefore, particularly at the beginning of the use, the oil film pressure at each axial end portion becomes higher when misalignment takes place, with the result that the bearing alloy layer is elastically deformed in the direction of compression. In consequence, the oil film thickness at opposite end portions is increased to prevent rupture of oil film, thus avoiding occurrence of metal contact.
摘要翻译：滑动轴承包括背面金属和在其上形成的轴承合金层，背面金属的厚度从中间部分朝向每个轴向端部逐渐减小，并且轴承合金层的厚度在每个轴向端部处增加。轴承合金层的杨氏模量比钢板的背面金属的杨氏模量小，因此容易弹性变形，特别是在使用开始时，各轴端部的油膜压力变高当发生不对准时，结果轴承合金层在压缩方向上弹性变形。因此，相对端部的油膜厚度增加，以防止油膜破裂，从而避免金属接触的发生。

In the working method and apparatus, a working holder 18 is provided which has a groove 20 extending on the inner peripheral surface in the peripheral direction and portions on both sides of the groove in the transverse direction formed in step-like shape, a half bearing 11 is housed in the working holder 18, and both ends of the half bearing 11 in the peripheral direction are pressed by use of pressing means 24. Then, the half bearing undergoes plastic deformation so as to be fitted into the groove and both sides of the half bearing in the axial direction thereof come into abutment with the edges 22, 23 of the step-like portions and are deformed in a polygonal line form. In this state, both ends of the half bearing 11 in the axial direction thereof are cut along one cylindrical surface by use of a broach 19. As a result, two inclined surfaces of different angles are continuously formed in the portions of both sides of the bearing alloy metal 13 of the half bearing in the axial direction thereof.

摘要： A method of manufacturing a multilayer material including a back metal and a metal plate made from a metal differing from the back metal is disclosed. The method includes heating powder of the metal formed into the metal plate in a reducing atmosphere so that an oxide on a surface of the metal powder is deoxidized, and spreading the deoxidized metal powder onto the back metal and irradiating laser beam having an energy density of 10 to 100 kW/cm2 onto the metal powder spread on the back metal so that the metal powder is partially heated to be melted, while the laser beam is moved relative to the spread metal powder, and quenching the melted part of the metal powder at an underside of the back metal so that the melted part is rapidly solidified, whereupon the multilayer material has a dendritic structure in which the metal plate extends substantially vertically from a surface of the back metal, and the dendritic structure has a crystal grain size equal to or smaller than 0.02 mm at a cut surface thereof parallel to a surface of the back metal and/or a dendritic arm spacing equal to or smaller than 0.02 mm at a cut surface thereof vertical to the surface of the back metal.

摘要： In order to enhance the fatigue resistance and the anti-seizure property while maintaining the embeddability, there is provided a plain bearing comprising a bearing alloy layer, an intermediate layer and an overlay layer sequentially formed on the inner surface of a back metal. The inner surface of the bearing alloy layer is provided with a recess “a” and protrusions “b”, thereby being made into a textured uneven surface. The protrusion has the shape of a oblique square at 45° relating to the circumferential direction, so that when a foreign particle X introduced between sliding surfaces of a shaft and the plain bearing is moved in the circumferential direction in accordance with the rotation of the shaft, the foreign particle X runs against a side edge of the protrusion “b” and moves along the side edge, thereby the embedding of the foreign particle X is promoted. If the foreign particle fails to be adequately embedded, the foreign particle leaves the side edge again.

摘要： A copper alloy sliding material which can bring about superior resistance to fatigue as well as good anti-seizure property without containing any Pb. The copper alloy sliding material is made to have the structure in which both of the hard copper alloy phase and the soft copper alloy phase coexist in a mixture state. On the surface of the sliding material, the soft copper alloy phase comes to have a shape more concave than that of the hard copper alloy phase when receiving a load or when being in a sliding wear relation, in which concave portions is retained lubricant with the result that the anti-seizure property is enhanced. Further, since the soft phase and the hard phase are made of the same copper alloy, the wettability thereof becomes good, and Ni and etc. contained in the hard copper alloy phase are diffused into the soft copper alloy phase, so that the hardness of the boundary portion defined between the phases come to be gradually varied. Thus, because of the unclear boundary, the load received in the hard phase comes to be spread in a wide range without being concentrated at the boundary, so that the fatigue strength is enhanced.

摘要： There is disclosed a sliding member which slidably contacts an counterpart member with friction and in which a friction force is varied without changing a contact pressure. A sliding member 11 is formed by covering a steel plate with sliding materials 13a to 13e different in friction coefficient. In this case, when a sliding direction of the counterpart member 14 is set to directions of arrows A and B, a sliding material 13a of a low friction coefficient is disposed in the middle, and the sliding materials 13b to 13e are arranged so that the friction coefficient gradually increases toward both terminal sides in the directions of arrows A and B of the sliding material 13a. According to the sliding member 11, the friction force increases as the counterpart member 14 moves in the directions of arrows A and B from the middle.
