    摘要： In order to provide a manufacturing process for a wheel nut wrench in which strength of a nut socket portion is increased even though the process is facilitated under a situation where a tube made of carbon steel such as S45C is used as a material, the process includes the steps of: using a tube-shaped steel tube, forming a nut socket shell portion having a cross section of a hexagonal shape at an end portion thereof by cold pressing, pressing a sleeve made by a belt-shaped steel plate being bent and having a cross section of a hexagonal shape into the nut socket shell portion, and unifying a nut socket portion with the sleeve by plastic deforming.

    摘要： Since lubricating oil is injected to a tooth of a small-diameter helical gear immediately before meshing begins, the injected lubricating oil can be captured between the small-diameter helical gear and a large-diameter helical gear and successively flow along meshing tooth surfaces. Therefore, lubrication of the tooth surface and cooling of the tooth surface can be simultaneously performed with an appropriate quantity of lubricating oil to enable a reduction in tooth surface wear and a longer gear life. Moreover, a lubricating oil film formed on the tooth surface makes it possible to prevent direct contact between the tooth surfaces of both the small-diameter helical gear and the large-diameter helical gear. Since a covered tooth surface effect is also obtained, the occurrence of pitching and scoring can be suppressed. By injecting lubricating oil directly to the small-diameter helical gear, which has a small heat capacity, a cooling effect thus obtained can suppress a temperature increase of the small gear. Moreover, the occurrence of tooth damage such as pitching and scoring caused by a temperature increase can also be greatly suppressed.

    摘要翻译： 由于在啮合开始之前将润滑油喷射到小直径斜齿轮的齿上，所以注入的润滑油可以被捕获在小直径斜齿轮和大直径斜齿轮之间，并且依次沿啮合齿表面流动。 因此，齿面的润滑和齿面的冷却可以用适量的润滑油同时进行，能够减少齿面磨损和延长齿轮寿命。 此外，形成在齿面上的润滑油膜可以防止小直径斜齿轮和大直径斜齿轮的齿面之间的直接接触。 由于也可以获得覆盖的牙齿表面效果，所以可以抑制俯仰和刻痕的发生。 通过将润滑油直接注入到具有小热容量的小直径斜齿轮上，由此获得的冷却效果可以抑制小齿轮的温度升高。 此外，还可以大大抑制由温度升高引起的诸如俯仰和划痕等牙齿损伤的发生。

    摘要： A hollow housing of a screw-type jack is integrally formed by a press. A ram is mounted in the center portion inside this housing in an axial direction to be extendable/contractible in a vertical direction. A drive mechanism mounted in the housing, for extending/contracting this ram in the vertical direction, and in which the housing includes a cylindrical shaft portion protrudingly disposed on a lower part of a side surface of the housing. A drive gear is pivotally and rotatably supported in the cylindrical shaft portion. The housing is made up of a plurality of housing pieces which are vertically divided portions of the housing. The housing pieces are mechanically joined to each other to form the housing. The housing pieces are divided in a vertical direction cutting though the axis of the cylindrical shaft portion. Joining of the housing pieces can use rivets or joining pieces can be swaged over protruding flanges.
