Aluminium Alloy Ratchet Sheave Gear for Marine Gearbox

The aluminium alloy ratchet sheave gear is a critical component in marine gearboxes, designed to ensure smooth torque transmission, controlled motion, and reliable anti-reverse performance. Manufactured from high-strength aluminium alloy, this gear offers an ideal balance of lightweight design, corrosion resistance, and durability, making it perfectly suited for harsh marine environments.

Compared to traditional steel gears, aluminium alloy gears reduce overall gearbox weight, improving vessel fuel efficiency and operational balance. Their natural corrosion resistance provides long service life even under constant saltwater exposure, while excellent thermal conductivity enhances heat dissipation during heavy-duty operations. Precision machining ensures accurate tooth geometry, smooth engagement, and consistent performance in demanding applications.

Applications in Marine Systems

Aluminium alloy ratchet sheave gears are widely used in:
1. Propulsion gearboxes
2. Auxiliary marine drive systems
3. Winches and lifting mechanisms
4. Offshore and naval equipment

At Belon Gear, we specialize in producing high quality aluminium alloy ratchet sheave gears for marine propulsion gearboxes, auxiliary drive systems, and winch mechanisms. With advanced CNC machining, strict quality control, and compliance with ISO and AGMA standards, our gears deliver reliability, efficiency, and long-term performance for modern marine engineering.

Internal gear Definition

An annular gear having teeth on the inner surface of its rim. The internal gear always meshes with an external gears like spur gears.

Features of helical gears:

1. When meshing two external gears, the rotation occurs in the opposite direction, when meshing an internal ger with an external gear the rotation occurs in the same direction.
2. Care should be taken with regard to the number of teeth on each gear when meshing a large (internal ) gear with a small (external) gear, since three types of interference can occur.
3. Usually internal gears are driven by small external gears
4. Allows for a compact design of the machine

Applications of Internal gears: planetary gear drive of high reduction ratios, clutches etc.
