Hệ thống khớp nối vạn năng và trục Cardan của máy phay

Mô tả

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.

Tổng quan sản phẩm

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.

Thông số kỹ thuật

Nguyên lý hoạt động

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.

Lợi thế cốt lõi

Cấu trúc và kỹ thuật chế tác vật liệu

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.

Các kịch bản ứng dụng điển hình

Hệ thống truyền động chính của nhà máy cán thép: Connects the motor or gearbox to the work rolls while accommodating roll changes, thermal growth, and misalignment in hot and cold rolling stands.

Máy đúc liên tục: 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.

Hướng dẫn lựa chọn

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.

Câu hỏi thường gặp

Q: What balancing grade is recommended for high-speed mill applications?
A: G6.3 là tiêu chuẩn cho hầu hết các ứng dụng. G2.5 hoặc tốt hơn có sẵn cho các dây chuyền tốc độ cao quan trọng để giảm thiểu rung động.

Hỏi: Các trục này có thể chịu được độ lệch tối đa là bao nhiêu?
A: Standard designs handle up to 25 degrees angular misalignment per joint. Higher angles are possible with special joint configurations.

Hỏi: Có thể bù trừ chiều dài do giãn nở nhiệt không?
A: Yes. Telescopic or spline sections are available to absorb axial movement caused by temperature changes in mill stands.

Hỏi: Thông thường cần bảo trì những gì?
A: Bôi trơn sau mỗi 500 đến 1000 giờ hoạt động hoặc mỗi 3 đến 6 tháng tùy thuộc vào tải trọng và môi trường. Nên kiểm tra định kỳ các gioăng và ổ bi.

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.
