Product Structure & Components
Integral Forged Fork Head – One-piece construction without bolt connections – eliminates bolt loosening and breakage, the most common failure point in traditional universal joints. The SWC series uses an integral fork structure where bearings are fixed without bolts, avoiding loose bolt breakage and simplifying maintenance.
Cross Shaft Assembly (Spider) – Precision cross shaft with multi-row needle roller bearings for high wear resistance and strength. Equipped with grease fittings (注油孔) for easy lubrication.
Telescopic Welded Shaft – Standard telescopic design with customizable stroke compensates for axial displacement.
48-Tooth Face Flange Connection – Features precisely machined interlocking teeth on the flange face (48 teeth, groove angle 5.14°) for accurate alignment and secure torque transmission under heavy shock loads and reversing operations.
Alloy Steel Construction – 42CrMo or 40Cr with quenching process – high strength and durability. Raw blanks are refined via quenching and tempering, while spline shafts undergo intensive induction hardening.
💡 How it works: The SWC190 cardan shaft uses an integral fork head design that eliminates the weak link of bolt compression bearing seats, completely avoiding common malignant damage caused by bolt loosening or breaking. Torque is transmitted through the cross shaft, while the telescopic shaft accommodates axial displacement. The 48-tooth face flange connection provides superior alignment and torque transmission under heavy loads. The integral fork design provides 30-50% longer service life than bolt-connected designs. The SWC type offers greater angle compensation capability (15-25°) compared to SWP type (~10°).
Flange Connection Types – Choose the Right One
The SWC190 supports multiple flange connection types. The face-tooth/claw flange is specifically designed for heavy-duty applications:
| Connection Type | Features | Best For |
|---|---|---|
| Face-Tooth/Claw Flange (48 Teeth) | Interlocking teeth on flange face provide precise alignment, high torque transmission, and excellent impact resistance. Groove angle 5.14° | Heavy shock loads, frequent reversing operations, ship drives, rolling mills |
| Standard Bolt Flange | Torque transmitted through bolt preload | Light to medium loads, smooth operation |
| Key-Type Flange | Keys and keyways provide positive torque transmission | Medium-duty applications |
✅ The face-tooth/claw flange with 48 teeth is the preferred choice for heavy-load applications such as ship propulsion systems, medium-section steel rolling mills, and crane main drives, effectively preventing connection loosening under impact loads.
