밀 유니버설 조인트 및 카르단 샤프트 시스템

설명

Universal joint and cardan shaft systems are essential for transmitting high torque in rolling mills, continuous casters, and heavy processing lines where misalignment, thermal expansion, and dynamic movement must be accommodated. These flexible drive components ensure reliable power transmission while protecting connected equipment from harmful forces.

제품 개요

These drive shaft systems serve hot and cold rolling mills, continuous casting machines, and heavy material handling equipment. Core strengths include high torque capacity up to 1,000 kNm, excellent angular and parallel misalignment tolerance, robust forged construction, and the ability to absorb thermal expansion and vibration in demanding mill environments.

기술적 매개변수

작동 원리

Each universal joint consists of a precision-machined cross supported by heavy-duty bearings inside forged yokes. This design allows continuous torque transmission while accommodating significant angular and parallel misalignment between the driving and driven components. Intermediate tube sections connect the joints and may include telescopic or spline features to absorb axial movement caused by thermal expansion or mill stand adjustments.

핵심 이점

구조 및 재료 장인정신

Shaft tubes are produced from seamless high-strength alloy steel and precision machined for balance. Universal joint crosses and yokes are forged from high-grade alloy steel and heat-treated for fatigue resistance. Heavy-duty needle or roller bearings support high torque and angular movement. Multiple sealing stages protect internal components from dust, moisture, and lubricant loss in harsh mill environments.

일반적인 적용 시나리오

압연기 주 구동 장치: Connects the motor or gearbox to the work rolls while accommodating roll changes, thermal growth, and misalignment in hot and cold rolling stands.

연속 주조기: Provides flexible power transmission to withdrawal and straightening units where long distances and dynamic movement occur.

Heavy Material Handling: Transmits torque to large conveyors, transfer cars, and positioning systems in steel and mining operations.

선택 가이드

Determine maximum continuous and peak torque requirements. Calculate total shaft length and maximum angular misalignment. Assess axial movement needs caused by thermal expansion or mill adjustments. Choose appropriate joint size, tube diameter, and balancing specification. Verify flange compatibility with existing equipment and consider environmental factors such as dust, temperature, and vibration. Review service access and any requirements for telescopic features or special coatings.

자주 묻는 질문

Q: What balancing grade is recommended for high-speed mill applications?
A: G6.3은 대부분의 용도에 표준입니다. 진동을 최소화하기 위해 중요한 고속 생산 라인에는 G2.5 이상의 제품을 사용할 수 있습니다.

질문: 이 축들은 어느 정도의 축 정렬 불량을 견딜 수 있습니까?
A: Standard designs handle up to 25 degrees angular misalignment per joint. Higher angles are possible with special joint configurations.

질문: 열팽창에 따른 길이 보정을 포함할 수 있습니까?
A: Yes. Telescopic or spline sections are available to absorb axial movement caused by temperature changes in mill stands.

질문: 일반적으로 어떤 유지보수가 필요합니까?
A: 윤활은 부하 및 환경에 따라 500~1000 작동 시간마다 또는 3~6개월마다 실시해야 합니다. 씰과 베어링에 대한 정기적인 점검을 권장합니다.

Q: Are spare universal joint kits readily available?
A: Yes. Common joint sizes, crosses, bearings, and seals are stocked for rapid dispatch to minimize production downtime.
