Can the gearbox be connected rigidly to the engine shaft?

No, rigid connections are forbidden. We recommend uniform bracket installations on rigid supports or using high-elastic couplings if the engine uses elastic support.

What types of vessels are these gearboxes suitable for?

They are suitable for a wide range of vessels including cargo ships, container ships, bulk carriers, tankers, fishing vessels, passenger vessels, and scientific research ships.

How is the transmission capacity determined?

Transmission capacity is expressed as the engine's continuous power to rated speed ratio. It is critical to select the gearbox beneath manual specifications based on the reduction ratio.

AI-Powered supplier vetting

SummaryThe supplier operates in marine propulsion, gearboxes, propellers, bearings, coatings, firefighting systems, ship maintenance, and related mechanical and engineering equipment. It reports product R&D, application design, processing and production, spare-parts supply, technical support, ship repair, and shipbuilding-equipment support. Customization is offered across several modes, including sample-, design-, full-, minor-, and flexible customization. Export activity is substantial, with 51%–70% of sales from exports and Europe identified as a primary market. However, quality documentation is limited, with finished-product inspections conducted under instructions but without written records, and only one quality inspector reported. The supplier has R&D documentation and AutoCAD capability but no patents, SDK, or popular-brand OEM service. Overseas service infrastructure and trade-show participation are absent. Financial and sustainability information is present only as year references or unknown-status...

Supplier typeThe supplier is a marine and industrial equipment manufacturer and service provider, covering propulsion systems, gearboxes, propellers, bearings, firefighting systems, coatings, generators, machinery, and ship repair or engineering support. Its stated integration of R&D, production, spare-parts supply, technical support, and shipbuilding-equipment support indicates a broad full-service industrial supplier profile.

After-Sales capabilityThe supplier explicitly provides after-sales service for ship maintenance, ship repair, technical support, spare-parts supply, and related marine engineering support. However, it reports no overseas showroom, overseas agent or branch, or countries with overseas services, indicating that international local-service coverage is limited.

Production capacityThe supplier reports processing and production, marine and industrial equipment manufacturing-related activities, and annual output in the stated US$50 million–US$100 million range. It also has export operations and integrated equipment-support activities, supporting established production capability; however, quality control resources are limited, with one inspector reported and no written finished-product inspection records.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its R&D responsibilities include developing and designing new products to meet customer customization needs, with design review, verification, and validation documentation available.

Product Q&A

Q:What are the main functions of this marine gearbox?

The gearbox provides speed reduction, forward and reverse clutching, and propeller thrust bearing capabilities, integrating seamlessly with the main engine.

Q:What materials are used for the gears and housing?

Gears are crafted from low-carbon alloy steel (e.g., 20CrMnMoH) with carburizing and quenching. The housing is made of high-grade gray cast iron (HT200/HT250) to reduce vibration and noise.

Q:What control methods are available?

Control options include push-and-pull flexible shaft, electric, and pneumatic systems, depending on the specific model and customer requirements.

Q:Is customization available for these gearboxes?

Yes, we offer full customization, minor customization, and flexible customization from samples or designs to meet specific vessel needs.

Q:What is the typical lead time for production?

The lead time varies by season: within 15 workdays during the off-season, and 1-3 months during the peak season.
