Gear Yoke for PTO Shaft — Involute Spline Connection for Torsion-Free PTO Drives
这 Gear Yoke for PTO Shaft represents the pinnacle of PTO tube-to-yoke connection technology. Unlike triangular, lemon, or star profiles relying on form-fit engagement, the gear yoke employs an involute gear-tooth bore meshing with a matching external gear profile on the PTO tube. This involute spline interface distributes load across all teeth simultaneously, resulting in virtually zero backlash, minimal vibration, and exceptional torque density. Manufactured with gear-hobbing and shaving processes that achieve AGMA Class 8 tooth accuracy.

⭐ 主要特点和优势
⚙ Involute Gear-Tooth Bore
Full-circumference contact with tube teeth eliminates backlash and distributes torque uniformly.
📐 Zero Backlash Connection
Play-free connection ideal for precision planters and hydraulic drives.
💪 Exceptional Torque Density
Gear splines carry more torque per unit bore diameter than any other profile.
🔧 AGMA Class 8 Tooth Accuracy
Hobbed and shaved teeth ensure consistent meshing, low noise, long life.
🔥 Carburized Tooth Surfaces
Tooth flanks carburized to HRC 60+ for extreme wear resistance.
🛡 Smooth Telescoping Action
Gear mesh permits smooth, consistent axial sliding without stick-slip.
🔄 兼容性信息
Fits all standard gear-profile PTO tubes in Series 2G through 50G. Compatible with Walterscheid, Bondioli & Pavesi, Comer, AW Dynamik. Particularly well-suited for precision implements, hydraulic pump drives, vineyard/orchard equipment, and vibration-critical applications.
📚 选择指南
Step 1 — Confirm Gear Profile: Gear tubes have evenly spaced teeth. Count teeth and measure OD to identify series.
Step 2 — Match Series Number: Cross-reference tube OD (B) with specs. Gear yokes use G suffix.
Step 3 — Evaluate D Dimension: .06G for heavy-duty cross kits; .07G for standard applications.
🌾 典型应用场景
GPS-guided planters, precision seeders, variable-rate applicators
PTO-driven hydraulic pump sets, mobile hydraulic power units
Under-vine cultivators, orchard sprayers, narrow-row mowers
Generators, compressors, conveyors requiring zero-backlash PTO
🛠 安装和使用指南
- Verify gear tooth count: Ensure yoke and tube have same number of teeth and same module.
- Apply anti-seize compound: Lightly coat teeth to prevent galling during initial operation.
- Engage teeth carefully: Rotate yoke slightly while pressing onto tube for smooth meshing.
- Secure axially: Install appropriate retaining mechanism.
- Install cross kit: Mount universal joint cross and secure bearing caps.
- Test for backlash: Assembled shaft should exhibit near-zero rotational play.
