Problems solved by technology

Although the braid has the characteristics of high strength, high temperature resistance, corrosion resistance, and small friction coefficient, it is difficult to bond with other materials due to the low surface tension of the PTFE material. During the long-term operation of the bearing, the wear-resistant fabric Easy to peel off from the metal bushing, resulting in failure of the moving parts of the bearing
In addition, the thickness of the single-layer braid is thin, which leads to low PTFE accumulation thickness. When the bearing runs for a long time, it is easy to cause the sliding material to wear out and the self-lubricating bearing will fail.

Embodiment 1

[0054] The surface warp and surface weft yarns are all made of polytetrafluoroethylene filaments with a denier of 440dtex and 60 filaments, and the inner warp and weft yarns are all polyester fibers with a denier of 110dtex and 48 filaments. The surface layer and the inner layer are set to adopt 1 / 1 plain weave, and the above-mentioned polytetrafluoroethylene fiber layer and the polyester fiber layer are bonded together by the surface warp bonding method, and then weaved by a rapier loom to obtain a covering Self-lubricating double layer fabric with factor 2100. In the double-layer fabric, the number of junction points in a complete loop organization accounts for 2.0% of the total number of stitches, and there are at least 4 warp yarns and 2 weft yarns between two adjacent junction points. The prepared self-lubricating double-layer fabric was placed in an environment with a temperature of 20 ± 2°C and a humidity of 65 ± 4% for humidity conditioning treatment, and the character...

Abstract

The invention discloses a self-lubricating double-layer fabric and application thereof. The double-layer fabric is formed by connecting a polytetrafluoroethylene fiber layer with a fiber layer formedby other fibers through bonding points, and the number of the binding points in one complete circulation structure in the double-layer fabric accounts for 0.2-5.0% of the total structure number. The self-lubricating double-layer fabric has the advantages of good abrasion resistance and high peel strength, and can be applied to plane or curved surface or linear motion parts.

Description

technical field [0001] The invention relates to a self-lubricating double-layer fabric and its application. Background technique [0002] Traditional sliding bearings are generally made of metal materials. Due to the addition of lubricating oil to traditional bearings, there are problems such as oil leakage and oil dripping. Some occasions are restricted in use, such as underwater operations; in addition, traditional bearings require Lubricating oil is often added, and it is also restricted for use in some places where maintenance is difficult, such as high-altitude operations. These have greatly limited the occasions where traditional bearings cannot be applied to lubricating oil. Therefore, it is necessary to develop an oil-free lubricated bearing. [0003] For a long time, fluororesin has been laminated and coated on the surface of sliding parts due to its low coefficient of friction, but pure fluororesin has poor non-adhesiveness and wear resistance, and is easy to pee...
