[0070] For the above-mentioned sliding support portion 2, test bodies (Examples 1 to 4) in which the conditions of the sliding member 21, the counterpart member 22, and the lubricant were set as shown in Table 1 below were prepared, and the surface of the counterpart member 22 was produced. The test bodies (comparative examples 1 and 2) under different conditions were subjected to a constant-velocity alternating cyclic load test.

[0071]Here, in each test body of Examples 1 to 4 and Comparative Examples 1 and 2, the sliding member 21 is made of tetrafluoroethylene resin with a filler added, and has a diameter dimension φ of 100 mm and a thickness dimension of 4 mm. The disc-shaped sliding member body 24 has a Young's modulus of 600 MPa. In addition, in the test bodies of Examples 1 to 4, the opposite member 22 was constituted by spraying epoxy resin paint on the surface of the opposite member main body 26 made of a steel plate to form a film 27, and the film thickness of the ...

[0092] In the second experimental example, as the sliding member main body 24 of the sliding member 21, as in the first experimental example, a filler made of tetrafluoroethylene resin with a Young's modulus of 600 MPa and a diameter φ of 600 mm was used. , A disk-shaped sliding member main body 24 having a thickness dimension of 4 mm. In addition, as the counterpart member 22, as in the first experimental example, a member having a film 27 formed by spraying an epoxy resin material on the surface of a steel plate was used. The film thickness of the film 27 was 250 μm, and the Young's modulus of the film 27 is 5GPa. Furthermore, as a result of measuring the maximum height Rz (JIS B0601-2001 / ISO 4287) of the surface of the film 27 (second sliding surface 28), as shown in Table 3, when the reference length is 0.8 mm, Rz is 10.2 μm; when the reference length is 2.5 mm, Rz is 18.5 μm; when the reference length is 8 mm, Rz is 39.2 μm. In addition, as a lubricant, silicon grease h...

Abstract

Provided are a slide structure, a support structure and a seismically isolated structure wherein a slide member (21) has a first sliding surface (25) of a sliding body (24) made of synthetic resin and a counter member (22) has a second surface (28) covered with a skin (27) made of synthetic resin that has more than twice as large Young's modulus as that of the first sliding surface. The skin surface is roughened such that the maximum height Rz of roughness is more than 3[mu]m. Small pits on the roughened surface trap lubricant thereby preventing the lubricant from flowing out and thereby providing a stable and low friction state.

Description

technical field [0001] The present invention relates to a sliding structure, a supporting device and an anti-seismic structure. [0002] This application is based on Japanese Patent Application No. 2009-107618 filed in Japan on April 27, 2009 and enjoys the priority thereof, and the content thereof is incorporated herein. Background technique [0003] Conventionally, a device having a sliding member (first member) and a counterpart member (second member) facing each other is known as a sliding support device used for an earthquake-proof structure or the like. In this slide support device, the sliding member can slide along the surface of the counterpart member having a sufficiently large area, and a load can be transmitted from one of the sliding member and the counterpart member to the other. In such a sliding support device, it is important to reduce the coefficient of friction between the sliding member and the counterpart member on the sliding surface as much as possibl...
