摘要： A gasket having a concentrically waved metal sheet, i.e., a core member, which has a PTFE sheet or an inorganic sheet of sealing-property layered and bonded on each of its opposite surfaces. The gasket makes it possible to ensure a stable sealing-property for a long period of time with a low to a high fastening-load applied. The metal sheet has valley portions, which were conventionally vacant gaps, and are filled with powdered sealing member to be embedded from the beginning. Therefore, the PTFE sheet or the inorganic sheet at the valley portions of the metal sheet that conventionally could not be compressed with a low fastening-load applied is compressed and even with the low fastening-load applied can secure a fastening surface-pressure over the entire surface. Further, since it is possible to suppress the deformation of the sheet in quantity, which was conventionally large, the PTFE sheet or the inorganic sheet each of low-fluidity are arranged so as not to be broken with a high fastening-load applied and the thinner PTFE sheet or the thinner inorganic sheet can be used.
摘要翻译：具有同心圆波形的金属片，即芯构件的垫圈，其具有层压并结合在其每个相对表面上的PTFE片或密封性无机片。垫圈使得可以在施加低到高的紧固负载的情况下长时间确保稳定的密封性。金属片具有通常为空隙的谷部，并且填充有从一开始就嵌入的粉末密封构件。因此，通常在不能被施加的紧固负荷的情况下不能压缩的金属板的谷部处的PTFE片材或无机片材被压缩，并且即使施加的紧固负载也能够将紧固表面压力固定在整个表面。此外，由于可以抑制以往较大的片材的变形，所以PTFE片材或低流动性的无机片材布置成不被施加高的紧固负荷而破裂，并且可以使用更薄的PTFE片材或更薄的无机片材。

摘要： The present invention relates to an annular sliding fluoroplastics member which is requested to have good mechanical properties, resistance to abrasion and wear, thermal conductivity, heat resistance, and the like, and also to a method of producing such an annular sliding fluoroplastics member. The annular sliding fluoroplastics member of the invention has a composite structure which mainly consists of fluorine plastics and short fibers, and 20 or more wt. % of short fibers by weight of a total amount of the short fibers are oriented in a direction along which a burden of a load is large. According to this configuration, the buckling resistance and the pressure resistance are enhanced. A member having a high buckling resistance can be used in a thrust slide bearing or a thrust washer in which a large press load is applied in the axial direction, and a member having a high pressure resistance can be used in a radial slide bearing in which a large press load is applied in a radial direction. In some cases, in the annular sliding fluoroplastics member of the invention, filaments consisting of long fibers may be stitched to the inner peripheral face or the like, the surface is covered with an expanded graphite sheet, or the member is impregnated with a lubricant. The member having such a structure is excellent in buckling resistance and pressure resistance in a radial direction, and also in resistance to abrasion and wear, thermal conductivity, etc. According to the production method of the invention, a cutting work step can be omitted, and therefore materials can be prevented from being wastefully used, and the production cost can be reduced.

摘要： The packing according to the present invention is composed of a string-like body formed of an elongated tape-like packing material having at least one layer is repeatedly folded in direction at a right angle to the longitudinal direction thereof in a zigzag manner with peak portions and valley portions alternately formed. According to the packing, the string-like body cut into a predetermined length according to the diameter of a shaft with which it is to be used may be wound on the outer peripheral surface of the shaft with the width or thickness direction of the string-like body directed in the radial direction of the shaft. Thus, the packing is versatile with respect to the shaft diameter. The packing itself produces no slip in the axial direction of a shaft. This prevents the packing from protruding, thus eliminating stress release due to a decrease in volume. The packing is used with the string-like body folded in the three-dimensional directions. Accordingly, the shaft-following properties of the packing at the time when the same is worn, are satisfactory and the decrease in sealing properties is restrained.

摘要： A gasket having a concentrically waved metal sheet, i.e., a core member, which has a sheet of sealing-property layered and bonded on each of its opposite surfaces. The gasket has an enhanced adaptability of the sheet material and enables the thinner sheet to be used and at the same time makes it possible to ensure a stable sealing-property for a long period of time with a low to a high fastening-load applied. The metal sheet has valley portions, which were conventionally vacant gaps, and are filled with powdered sealing member to be embedded from the beginning. Therefore, the sheet at the valley portions of the metal sheet that conventionally could not be compressed with a low fastening-load applied can be compressed and even with the low fastening-load applied can secure a fastening surface-pressure over the entire surface. Further, since it is possible to suppress the deformation of the sheet in quantity, which was conventionally large, a sheet made of not only the high-fluidity material but also the low-fluidity material can be used as well as the thinner sheet.

At this time, the outer side of the cord-like member (40) is covered by a portion of the reinforcing member (20), and the remaining portion of the reinforcing member (20) is involved in the cord-like member (40). A large number of openings (20A) are formed in the reinforcing member (20), and the strip-like expanded graphite (3) faces the openings (20A). The expanded graphite (3) is engaged with the openings (20A), whereby the coupling force between the strip-like expanded graphite (3) and the reinforcing member (20) is enhanced. The shape-retaining property of the strip-like expanded graphite (3) is improved to enhance the sealing property, and the productivity is improved so that a material can be economically provided. Furthermore, carbon fibers or brittle fibers are placed outside of the cord-like member (40), so that a gland packing material (1) can be reinforced.
