Abstract:
The present invention provides structure of steel cord in heavy duty tires, in which the adhesive strength between filament and rubber, and penetrating property of rubber are improved by making the twist direction of core and strand different in the steel cord comprising core and strand filament, and by making the pitch or the twist period of core and strand different. In particular, this structure is applied to steel cord of 3+8*d(HT) which is used in heavy duty tires. In this application, twist direction of core filament is in the S direction and twist direction of strand filament is in the Z direction, and the ratio of the pitch of core filament (CP) and the pitch of strand filament (SP) is between 0.50 and 0.94.

Abstract:
PURPOSE: High tensile steel cord structure for a tire is provided to minimize the movement of the steel cord by sticking rubber to the steel cord firmly with infiltrating rubber to the steel cord, and to improve endurance by restricting corrosion with preventing the cord from being contacted to water or oxygen. CONSTITUTION: A steel cord of a tire is composed of a core filament and a strand filament. The core filament and the strand filament are twisted conversely, and the pitch as the twisting period of the core filament is different from the pitch of the strand filament. The rate of the core pitch to the strand pitch is formed to be within the range of 0.5-0.94. The steel cord is formed with adding 3 times core filament diameter to 8 times strand filament diameter. The rubber is stuck to the steel cord with twisting the steel cord and the rubber conversely.
Abstract:
The purpose of the present invention is to provide a hybrid core rope capable of reducing maintenance work or not requiring maintenance. The hybrid core rope (1) comprises: a resin solid core (2) having multiple spiral grooves (2a); multiple fiber chains (3) having fitful thickness for filling the spiral groove, and coiled in spiral shape on the outer periphery of the resin solid core along the spiral grooves; and multiple strands (4) coiled in spiral shape on the outer periphery of the solid core. The fiber chains and strands are coiled respectively, not having a parallel angle for each other.
Abstract:
거의 비 자전성일 뿐만 아니라 와이어의 마모 및 피로에 의해서 쉽게 파손되지도 않는 레이들 크레인과 같은 고하중의 크레인을 위한 와이어 로프가 제공된다. 이 비 자전 와이어 로프는 복수의 사이드 스트랜드를 갖는다. 각 사이드 스트랜드에 있어서, 와이어는 코어 스트랜드의 둘레에 코어 스트랜드 와이어와 동일 방향으로 꼬아진다. 사이드 스트랜드는 코어 스트랜드 와이어의 꼬임과 반대 방향으로 꼬아져서 와이어 로프를 형성한다. 사이드 스트랜드는 와이어 로프의 피치배수보다 작은 피치배수를 갖는 것이 바람직하다. 사이드 스트랜드의 직경과 코어 스트랜드의 직경 간의 비는 약 1.3 내지 약 1.8인 것이 바람직하다. 스트랜드의 피치배수는 약 5 내지 약 8인 것이 바람직하고, 와이어 로프의 피치배수는 약 8 내지 약 10인 것이 바람직하다. 코어 스트랜드와 사이드 스트랜드의 양자는 최외측 층에 편평한 표면을 갖는 성형 와이어를 구비하는 것이 바람직하다.
