3190-182 – Cv Double Joints Heads – 1310 CV FLANGE Series – Bolt Circle Dia 3.665 REC – Butt Dia 2.435

The 3190-182 is a 1310 CV FLANGE series CV double-joint head that cancels velocity error at operating angles where a single Cardan U-joint would cause second-order vibration. Its phased double-joint geometry and centering socket maintain constant output velocity through the full articulation range.

Constant-Velocity Principle in Double-Cardan Joints

A single Cardan U-joint operating at an angle produces an output shaft speed that varies sinusoidally at twice the input frequency. This variation is small at low angles (under 3 degrees) but grows rapidly with increasing angle. At 10 degrees, the speed fluctuation is noticeable as a vibration. The double-Cardan design uses two joints in series, phased so each joint variation is equal and opposite. A centering socket maintains the precise bisect angle between the joints to guarantee cancellation. The 3190-182 incorporates this design in the 1310 CV FLANGE series for high-angle shaft applications on trucks and off-road vehicles.

The butt-weld end accepts 2.560X0.067-inch driveshaft tube. Proper weld preparation -- clean, square-cut tube ends with the correct gap -- is essential for a runout-free finished shaft. After welding, dynamic balancing of the assembly ensures vibration-free operation throughout the operating speed range.

Assembly and Maintenance

• Grease both U-joint crosses and the centering socket through Zerk fittings before first use
• Relubricate every 30,000 miles or when operating in water-crossing or dusty conditions
• Confirm bolt circle matches the companion flange before final assembly
• After welding the tube, dynamically balance the completed shaft to specification
