    • A method of making a casting is disclosed. At least one support member has at least one first portion and a plurality of second portions connected to a mold core. The mold core is positioned at least in part in a sealed interior volume of a negative mold. The first portion is positioned outside the interior volume. The second portions are positioned at least in part inside the interior volume. A consumable pattern material is introduced into the negative mold to create a consumable pattern. The support member is disposed at least in part outside the consumable pattern. The consumable pattern is removed from the negative mold. A shell is formed around the consumable pattern. A casting material is introduced into an interior of the shell to create a final casting. The support member is disposed at least in part outside the final casting. A mold core is also described.
    • 公开了一种铸造方法。 至少一个支撑构件具有连接到模芯的至少一个第一部分和多个第二部分。 模芯至少部分地定位在阴模的密封内部体积中。 第一部分位于内部容积的外部。 第二部分至少部分地定位在内部容积内。 消耗图案材料被引入负模具以产生消耗图案。 支撑构件至少部分地设置在消耗图案之外。 将消耗品图案从阴模中取出。 围绕消耗品图案形成外壳。 将铸造材料引入壳体的内部以产生最终铸造。 支撑构件至少部分地设置在最终铸件的外部。 还描述了模具芯。

    • A rotor for an electrical generator is disclosed, including a rotor body having a circular portion and a cylindrical portion coaxial with the circular portion. A generally cylindrical recess is defined by the cylindrical portion and the first side of the circular portion for receiving a stator. At least one first wall is at least partially spaced apart from the first side of the circular portion, defining at least one chamber therebetween. The chamber has an inlet. An aperture in the at least one first wall defines an outlet of the at least one chamber. At least one second wall extends outwardly from the first side of the circular portion. The at least one second wall has an end portion adjacent to the inlet of the at least one chamber. An internal combustion engine with an electrical generator and a method of cooling an electrical generator are also disclosed.
    • 公开了一种用于发电机的转子,包括具有圆形部分的转子体和与圆形部分同轴的圆柱形部分。 大致圆柱形的凹部由圆柱形部分和用于接收定子的圆形部分的第一侧限定。 至少一个第一壁至少部分地与圆形部分的第一侧间隔开,在其间限定至少一个室。 腔室有一个入口。 所述至少一个第一壁中的孔限定所述至少一个室的出口。 至少一个第二壁从圆形部分的第一侧向外延伸。 所述至少一个第二壁具有与所述至少一个室的入口相邻的端部。 还公开了一种具有发电机的内燃机和冷却发电机的方法。
