3. Configuració i instal·lació
Installation of the Advance HCT800/1 Marine Gearbox requires specialized knowledge and equipment due to its size and complexity. It is strongly recommended that installation be performed by certified marine technicians or professionals experienced with heavy marine propulsion systems.
3.1 Comprovacions prèvies a la instal·lació
- Verify that the vessel's engine and propeller shaft are compatible with the gearbox specifications (input speed, ratio, flange dimensions).
- Ensure the mounting surface in the vessel is structurally sound and level to support the gearbox's 2700kg net weight.
- Inspect the gearbox for any visible damage incurred during shipping.
- Confirm all necessary ancillary components (e.g., hydraulic lines, cooling lines, control cables) are available and in good condition.
3.2 Mounting and Alignment
Precise alignment between the engine, gearbox, and propeller shaft is critical for optimal performance and longevity. Misalignment can lead to excessive vibration, premature wear, and potential failure.
- Carefully lift and position the gearbox using appropriate lifting gear, ensuring it is securely supported.
- Mount the gearbox to the vessel's foundation using high-strength fasteners, torqued to manufacturer specifications.
- Perform a thorough alignment procedure between the engine output shaft and the gearbox input, and between the gearbox output and the propeller shaft. This typically involves specialized alignment tools and techniques.
3.3 Fluid and Hydraulic Connections
- Connect all hydraulic lines for clutch engagement/disengagement and cooling systems according to the vessel's specific plumbing diagrams.
- Fill the gearbox with the recommended type and quantity of marine-grade transmission fluid. Refer to the specific fluid requirements for the HCT800/1 model.
- Bleed air from the hydraulic system as per standard procedures to ensure proper clutch operation.
4. Funcionament
The Advance HCT800/1 Marine Gearbox is designed for reliable operation when properly integrated into a marine propulsion system. Always refer to the vessel's specific operating manual and the engine manufacturer's guidelines for detailed operational procedures.
4.1 Comprovacions prèvies a l'operació
- Before starting the engine, ensure the gearbox is in neutral.
- Check the gearbox fluid level and ensure it is within the recommended range.
- Verify that all cooling water connections are secure and functioning.
- Inspect for any leaks around the gearbox seals and connections.
4.2 Implicació i desvinculació
- With the engine running at idle speed, engage the clutch smoothly and gradually to avoid shock loads on the transmission.
- Disengage the clutch smoothly when transitioning to neutral or stopping the vessel.
- Avoid rapid or abrupt changes in direction (forward to reverse) without allowing the engine to return to idle and the propeller to stop rotating.
4.3 Rated Input Speed
The gearbox is rated for an input speed of 1900 RPM. Operating consistently above this speed may lead to accelerated wear or damage. Monitor engine RPM to ensure it remains within the gearbox's specified limits.
5. Manteniment
Regular maintenance is crucial for the longevity and reliable performance of your Advance HCT800/1 Marine Gearbox. Adhere to a strict maintenance schedule as outlined in the vessel's overall maintenance plan and consult a qualified marine mechanic for complex procedures.
5.1 Routine Checks (Daily/Before Operation)
- Nivell de fluids: Check the gearbox oil level using the dipstick. Ensure it is between the minimum and maximum marks.
- Inspecció visual: Look for any signs of oil leaks, loose connections, or unusual wear.
- Temperatura: Monitor the gearbox operating temperature. Excessive heat can indicate a problem.
- Soroll/Vibració: Listen for any unusual noises or feel for excessive vibrations, which could signal internal issues.
5.2 Scheduled Maintenance (Periodically)
- Fluid Change: Replace the gearbox oil at recommended intervals (e.g., annually or after a certain number of operating hours). Always use the specified marine-grade transmission fluid.
- Substitució del filtre: Replace oil filters and any hydraulic filters as per the maintenance schedule.
- Inspecció del sistema de refrigeració: Check the gearbox oil cooler for blockages or corrosion. Ensure adequate water flow.
- Coupling Inspection: Inspect the flexible couplings between the engine and gearbox, and gearbox and propeller shaft, for wear or damage.
- Bolt Torque Check: Periodically check the torque of all mounting bolts and flange bolts.
