摘要： If the slot width is reduced with a decrease in the number of laminated plates of a ring, a die stress sharply increases, thereby hindering production. Elements satisfy (h/t) 40, where h is a slot width of the elements, t is a plate thickness thereof, and S is a head area thereof. Even if the slot width h is reduced, increasing the head area reduces a hydrostatic pressure applied in a punching process, and thus, reduces the load on a die. The present invention is preferably used in endless metal belts in which elements having a width on a pitch line of 24 [mm], and a ring is formed by laminating six plates.
摘要翻译： 如果槽的宽度随着环的层叠板的数量的减少而减小，则模具应力急剧增加，从而妨碍了生产。 元素满足（h / t）<1和（S / h）> 40，其中h是元素的槽宽度，t是板厚度，S是其顶部区域。 即使狭槽宽度h减小，增加头部面积减小了冲压加工中施加的静水压力，从而降低了模具上的负荷。 本发明优选用于环形金属带，其中节距线宽度为24 [mm]的元件和通过层压六个板形成的环。

摘要： A cooling structure of a rotary electric machine (10) that includes a rotating shaft (16), a rotor (18), and a stator (20) that includes a coil end (22), includes a coolant passage (38) that is included in the rotating shaft (16) and through which coolant flows, and a squirt hole (42) that is included in the coolant passage (38). The squirt hole (42) is included in the coolant passage (38). An opening portion of the squirt hole (42) is positioned on an outer peripheral surface of the rotating shaft (16) and to an outside of the coil end (22) in the axial direction. The squirt hole (42) squirts the coolant such that the coolant is distributed to an inner peripheral surface (C1, C2) of the coil end (22) and an end surface (A1, A2) of the coil end (22) in the axial direction.

摘要： Provided is a stator capable of reducing the possibility that the temperature of a stator core becomes non-uniform in axial and circumferential directions in a stator positioned so that its axial center extends substantially horizontally.
In a stator 20, fixing ridges 40 are respectively formed at circumferential locations of a cylindrical main body portion 30 of a stator core 21, and protrude radially outward from a main body outer peripheral surface 31 along an entire axial length of a main body portion 30. Of the fixing ridges 40, a fixing ridge 40 that satisfies the following conditions is selected as a target ridge 41: an uppermost part of a ridge outer peripheral surface 42 is located at the same height as, or lower than a horizontal plane extending in an uppermost part of the main body outer peripheral surface 31, and the uppermost part of the ridge outer peripheral surface 42 does not correspond to a boundary with the main body outer peripheral surface 31. The stator 20 includes sealing members 50, which are respectively attached to both axial ends of the stator core 21, and which respectively form sealing walls 51 that have a height equal to or higher than a horizontal plane extending in the uppermost part of the ridge outer peripheral surface 42. A recess surrounded by the ridge outer peripheral surface 42, the main body outer peripheral surface 31, and the sealing walls 51 serves as a refrigerant reservoir recess for storing a refrigerant.摘要翻译： 本发明提供一种定子，该定子能够降低定子的轴心在大致水平方向上延伸的定子的轴向和周向的温度不均匀的可能性。 在定子20中，固定用突条40分别形成在定子铁心21的圆筒状的主体部30的周向位置，并且沿主体部30的轴向全长从主体外周面31向径向外侧突出 ，在固定用突条40中，选择满足以下条件的固定用突条40作为对象突条41：突条外周面42的最上部位于与向内侧延伸的水平面相同的高度 主体外周面31的最上部和脊外周面42的最上部不与主体外周面31的边界对应。定子20具有密封部件50，该密封部件50分别安装 到定子铁芯21的两个轴向端部，并且分别形成高度等于或高于在t的最高部分延伸的水平面的高度的密封壁51 由脊外周面42，主体外周面31以及密封壁51围成的凹部成为收纳制冷剂的制冷剂积存用凹部。
