Deskripsi
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.
Gambaran Umum Produk
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.

Prinsip Kerja
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.
Keunggulan Utama
Handles peak torques up to 1,000 kNm in demanding rolling mill and heavy processing applications.
Accommodates significant angular and parallel misalignment without transmitting harmful forces to connected equipment.
Telescopic or spline sections absorb length changes caused by temperature variations in mill stands.
Heavy-duty forged yokes and precision-machined crosses ensure long service life under continuous heavy loads.
Precision balancing minimizes vibration, protecting bearings and improving overall drive system reliability.
Engineered to exact center distances and interface requirements for seamless integration into existing mill layouts.
Keahlian dalam Struktur dan Material
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.
Skenario Aplikasi Khas
Penggerak Utama Pabrik Penggilingan: Connects the motor or gearbox to the work rolls while accommodating roll changes, thermal growth, and misalignment in hot and cold rolling stands.
Mesin Pengecoran Kontinu: 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.
Panduan Seleksi
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.

Pertanyaan yang Sering Diajukan
Q: What balancing grade is recommended for high-speed mill applications?
A: G6.3 adalah standar untuk sebagian besar penggunaan. G2.5 atau yang lebih baik tersedia untuk jalur berkecepatan tinggi yang kritis untuk meminimalkan getaran.
T: Seberapa besar ketidaksejajaran yang dapat ditampung oleh poros ini?
A: Standard designs handle up to 25 degrees angular misalignment per joint. Higher angles are possible with special joint configurations.
T: Apakah kompensasi panjang dapat disertakan untuk ekspansi termal?
A: Yes. Telescopic or spline sections are available to absorb axial movement caused by temperature changes in mill stands.
T: Perawatan apa saja yang biasanya diperlukan?
A: Pelumasan setiap 500 hingga 1000 jam operasi atau setiap 3 hingga 6 bulan tergantung pada beban dan lingkungan. Inspeksi rutin pada seal dan bantalan dianjurkan.
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.
