    Abstract: PROBLEMS
    Local stress concentration caused by rotational moment transmitted from a crankshaft is eased.
    MEANS FOR SOLVING PROBLEMS
    A crankshaft (6) and an mounting hole (5) have two main circular arc parts (11, 21) on the same circle; and two connecting parts (12, 22) for connecting the adjacent main circular arc parts (11, 21), and have a cross-sectional shape in which the connecting parts (12, 22) facing each other are substantially parallel. The connecting parts (22) of the mounting hole (5) are formed in the shape of a large circular arc which projects inward. The torque of the crankshaft (6) is transmitted to the mounting hole (5) in a state where the connecting parts (12) of the crankshaft (6) and the connecting parts (22) of the mounting hole (5) which are formed in the shape of a large circular arc come into line contact with each other; therefore, the value of any local stress generated in the mounting hole (5) can be reduced.

    Abstract translation: 问题从曲轴传递的旋转力矩引起的局部应力集中减轻。 解决问题的手段曲轴（6）和安装孔（5）在同一个圆上具有两个主圆弧部分（11,21）; 以及用于连接相邻的主圆弧部分（11,21）的两个连接部分（12,22），并且具有彼此面对的连接部分（12,22）基本上平行的横截面形状。 安装孔（5）的连接部（22）形成为向内突出的大圆弧的形状。 在曲轴（6）的连接部（12）和安装孔（5）的连接部（22）形成的状态下，曲轴（6）的扭矩传递到安装孔（5） 大圆弧的形状相互接触; 因此，可以减小在安装孔（5）中产生的任何局部应力的值。

    Abstract: A multi-layer sliding part has a Cu-plated solid lubricant uniformly dispersed in the matrix of a sintered bronze powder. The sintered alloy layer is densified by pressing, and the surface of the bearing alloy layer is coated with a resin having sliding properties. In a method of manufacturing a multi-layer sliding part, a mixture of a bronze powder and a Cu-plated solid lubricant are initially sintered, and the initially sintered mass is pulverized. The pulverized powder is sintered on both sides of a backing plate. After sintering of the pulverized powder on both sides of the backing plate to form bearing alloy layers, the bearing alloy layers are pressed and densified. After densification, the bearing alloy layers are annealed, again pressed, and then coated with a resin having sliding properties.

    Abstract translation: 多层滑动部件具有均匀分散在烧结青铜粉末的基体中的镀Cu固体润滑剂。 烧结合金层通过压制致密化，轴承合金层的表面涂覆有具有滑动性的树脂。 在制造多层滑动部件的方法中，最初烧结青铜粉末和镀Cu固体润滑剂的混合物，并将最初烧结的物料粉碎。 粉碎的粉末在背板的两面烧结。 在背板的两侧烧结粉碎粉末之后，形成轴承合金层，对轴承合金层进行压制和致密化。 在致密化之后，将轴承合金层退火，再次压制，然后用具有滑动性能的树脂涂覆。
