    摘要： The lip-type seal of the present invention includes a seal ring made of an elastic material so as to have an annular fitted part that is fitted to a housing and a lip part that extends from the fitted part inwardly in a radial direction in the shape of a substantially conical ring and that is brought into contact with a shaft, and a support ring including an annular joint part joined to the fitted part and an annular supporting part that defines a hole through which the shaft passes, that extends from a side of the joint part to a halfway area of the lip part, and that supports the lip part from inside in a radial direction. The lip part is tapered in cross section from an area from which non-contact with the supporting part starts toward an end thereof.

    摘要： The lip-type seal of the present invention is a lip-type seal with which the outer periphery of a rotational shaft (S) supported by a predetermined housing (H) is sealed. This lip-type seal includes a seal ring (20) made of an elastic material so as to have an annular fitted part (21) that is fitted to the housing and a lip part (23) that extends from the fitted part inwardly in a radial direction in the shape of a substantially conical ring and that is brought into contact with the shaft, and a support ring (30) including an annular joint part joined to the fitted part and an annular supporting part (33) that defines a hole (30a) through which the shaft passes, that extends from a side of the joint part to a halfway area of the lip part, and that supports the lip part from the inside in the radial direction. In this lip-type seal, the lip part (23) is tapered in cross section from an area from which noncontact with the supporting part (33) starts toward an end thereof. Therefore, wear is reduced in a high-pressure environment, and durability is improved while securing a desired sealing capability.

    摘要翻译： 本发明的唇形密封件是密封由预定壳体（H）支撑的旋转轴（S）的外周的唇型密封件。 这种唇形密封件包括由弹性材料制成的密封环（20），以具有装配到壳体的环形装配部分（21）和从装配部分向内延伸的唇部（23） 径向方向为基本圆锥形的环并与轴接触的支撑环（30），支撑环（30）包括连接到装配部分的环形接头部分和限定孔的环形支撑部分（33） 如图30（a）所示，轴从该接合部分的一侧延伸到唇部的中间区域，并且从径向向内侧支撑唇部。 在这种唇形密封件中，唇部（23）从与支撑部（33）不接触的区域朝向其端部的横截面呈锥形。 因此，在高压环境中磨损降低，并且在确保期望的密封能力的同时提高耐久性。
