4. Configuració i instal·lació

Proper installation is crucial for the safe and efficient operation of the universal joint. It is recommended that installation be performed by a qualified professional.

1. Requisit dels components: The Wuj6 Universal Joint must be fitted at both ends of a torque tube to ensure proper power transmission and alignment.
2. Self-Aligning Bearing Integration: If a self-aligning bearing is incorporated into the system, one universal joint is sufficient to connect the two torque tubes.
3. Angle Balancing: When installing, strive to balance the angle at each joint. This practice minimizes stress on the components and optimizes operational efficiency.
4. Subjecció segura: Ensure all bolts and fasteners are tightened to the manufacturer's specified torque settings. Refer to the specific torque tube or gearbox manual for these values.
5. Comprovació prèvia al funcionament: Before initial operation, verify that all connections are secure and that the joint moves freely within its intended range of motion without binding.

5. Directrius de funcionament

The Lewmar Wuj6 Universal Joint is designed to operate within specific angular limits to ensure longevity and performance.

• Maximum Working Angle: The AMK10 Universal Joints (and by extension, the Wuj6, given its similar design principles and application) have a maximum permissible working angle of 25°. Exceeding this angle can lead to premature wear and failure.
• Self-Aligning Bearing Angle: If your system utilizes self-aligning bearings, note that these typically work effectively up to an angle of 15°.
• Funcionament suau: Ensure the system operates smoothly without excessive vibration or noise, which could indicate misalignment or an angle exceeding limits.

6. Manteniment

Regular maintenance is essential to ensure the continued reliability and performance of your Lewmar Wuj6 Universal Joint.

• Inspecció de rutina: Periodically inspect the universal joint for any signs of wear, corrosion, cracks, or loose fasteners. Pay close attention to the articulating components and bolted connections.
• Lubricació: While specific lubrication requirements are not detailed, it is generally good practice to ensure all moving parts are adequately lubricated according to the overall system's maintenance schedule. Consult the gearbox or torque tube system manual for specific lubrication guidelines.
• Neteja: Keep the joint clean and free from debris, dirt, or corrosive substances that could impede its movement or accelerate wear.
• Comprovació de fixació: Regularly check and re-torque all fasteners to ensure they remain secure, especially after initial break-in periods.
• Substitució: If significant wear or damage is observed, replace the universal joint immediately to prevent further system damage or failure. Use only genuine Lewmar replacement parts.

7. Solució De Problemes

Should you encounter issues with your Lewmar Wuj6 Universal Joint, consider the following general troubleshooting steps. For complex issues, professional assistance is recommended.

• Vibracions o sorolls excessius:
  • Check for proper alignment of the torque tubes and connected components.
  • Verify that the operating angle does not exceed the maximum permissible angle (25°).
  • Inspect for loose fasteners or worn components within the joint.
• Binding or Restricted Movement:
  • Ensure no foreign objects are obstructing the joint's movement.
  • Check for signs of corrosion or damage that might impede articulation.
  • Confirm that the joint is not being forced beyond its design limits.
• Desgast prematur:
  • Review installation for correct alignment and balanced angles.
  • Ensure regular maintenance and lubrication schedules are being followed.
  • Verify that the joint is used within its specified load and speed parameters.

If problems persist, contact Lewmar customer support or a certified service technician.
