Problems solved by technology

[0004] However, in the above-mentioned cylindrical sealing member, the durability of the fluff and fibers is low, and if powder enters between the fluff and fibers, the sealing performance is reduced, so it cannot be used under a high load for a long time.

Embodiment Construction

[0020]

[0021] Below, refer to figure 1 A sealing material according to one embodiment of the present invention will be described in detail.

[0022] Such as figure 1 As shown in (a), the sealing material 1 of the present embodiment is a cylindrical (ring-shaped) member, and includes a sliding layer 2 , an elastic sheath layer 3 , and fastening fibers 4 as its constituent members. Hereinafter, each constituent member of the sealing material 1 of the present embodiment will be described in order.

[0023] (sliding layer)

[0024] The sliding layer 2 is a cylindrical member, more specifically, a cylindrical member. The sliding layer 2 has an insertion hole 21 . The insertion hole 21 is a portion through which the rod-shaped body is slidably inserted. Specifically, the rod-shaped body of this embodiment inserted into the insertion hole 21 is as described later. figure 2 A cylindrical shaft 101 is shown. The shaft 101 is a member that performs relative movement such as ...

Abstract

Provided are a sealing material (1) and a sealing mechanism using same, the sealing material (1) being provided with: a tubular sliding layer (2) having an insertion hole (21)in which a rod-shaped body is slidably inserted and comprising a material obtained by integrating fibers and an elastic material; an elastic outer skin layer (3) that is laminated on the outer circumferential surface (22)of the sliding layer (2); and fastening fibers (4), which are continuously wrapped around at least once along the circumferential direction on the inside of the elastic outer skin layer (3) or on the outer circumferential surface of the elastic outer skin layer (3), in a state in which contact is not made with the outer circumferential surface (22)of the sliding layer (2).

Description

technical field [0001] The present invention relates to a sealing material and a sealing mechanism for sealing the periphery of a rod-shaped body. Background technique [0002] There is known a seal that seals around the rod-shaped body. Such seals are generally made of rubber or the like. Therefore, when used under a high load for a long period of time, there is a problem that creep deformation of the rubber occurs to reduce the compressive force toward the rod-shaped body, thereby reducing the sealing performance. [0003] Patent Document 1 describes a cylindrical sealing member that seals a rotating shaft of an image processing apparatus that handles powder as toner to prevent leakage of the powder. As this sealing member, fluff or fiber is formed into a cylindrical shape, and the outer peripheral side thereof is restrained by a metal support member, and pressed into the periphery of the shaft with an appropriate compressive force to achieve a balance between sliding res...
