Problems solved by technology

[0008] However, the composite material of silicon carbide and carbon in the prior art using carbon fiber has a high coefficient of friction because it is used for brake discs, and it is difficult to use it as a sealing sliding part that requires a material with a low coefficient of friction. Good sliding and sealing properties

Embodiment Construction

[0032] figure 1 It is a perspective view of a seal sliding member according to an embodiment of the present invention. The seal sliding member 10 is disposed, for example, in a boundary portion between a rotating member that rotates along with a rotating shaft and a stationary member that does not rotate in the interior of the mechanical seal device. Typically, the seal slide member 10 is used as a pair of a seal slide member fixed to the rotating member side and a seal slide member fixed to the stationary member side. The sliding member 10 has a sliding surface 20 that slides against the other sliding member used as a pair, and the fluid is sealed by the sliding sliding surface 20 . figure 1 The shown sliding member 10 has an annular outer shape with a through-hole in the center, and one of the surfaces perpendicular to the through-hole is the sliding surface 20 , and the shape of the sliding member is not particularly limited. In addition, the seal sliding member of the pr...

Abstract

[Problem] To provide a sliding seal member that is provided with the characteristics of silicon carbide, which are hardness and low wear, and is provided with suitable sealing and lubricating properties. [Solution] A sliding seal member that has a sliding face that slides with respect to other members and that seals a fluid via the sliding face is characterized by having carbon fibers with the lengthwise direction of the fibers arranged to be substantially parallel with respect to the sliding face, and silicon carbide that is provided between the plurality of carbon fibers.

Description

technical field [0001] A sealing sliding part used for mechanical seals and the like in the present invention. Background technique [0002] As a seal sliding member used for a mechanical seal or the like, a seal sliding member containing silicon carbide has been proposed. Silicon carbide is a material that has good heat resistance, high Young's modulus, is hard, and can realize low-wear sliding parts. On the other hand, since silicon carbide material itself lacks self-lubricating properties, sealing sliding parts using silicon carbide There is a problem that it is difficult to use in a dry environment where the lubricity of the fluid is lacking. In addition, the sealing sliding part using silicon carbide has the problem that it is hard but has low toughness and is fragile. [0003] On the other hand, in the field of brake discs, a technique for compensating the problems of the silicon carbide material by using carbon fibers has been proposed (see Patent Document 1, Patent...
