China OEM 3: 1 Advance / CZPT /Fenjin Marine Gearbox 120c Marine Diesel Engine components of gearbox

Product Description


3:1 Advance / CZPT /Fenjin Marine Gearbox 120C 

The diesel engine has the highest thermal efficiency (engine efficiency) of any practical internal or external combustion engine due to its very high expansion ratio and inherent lean burn which enables heat dissipation by the excess air. A small efficiency loss is also avoided compared to two-stroke non-direct-injection gasoline engines since unburned fuel is not present at valve overlap and therefore no fuel goes directly from the intake/injection to the exhaust. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) can have a thermal efficiency that exceeds 50%.

Different Types of Gearboxes and Their Applications

There are several types of gearboxes, each designed for specific applications based on their characteristics and capabilities. Here are some common types and their applications:

  • Spur Gearbox: Spur gearboxes consist of parallel-shaft gears with straight teeth. They are simple and economical, suitable for low-speed and low-torque applications such as conveyors, machine tools, and clocks.
  • Helical Gearbox: Helical gearboxes have helical teeth that provide smoother and quieter operation compared to spur gears. They are used in various industries, including automotive, construction, and mining equipment.
  • Bevel Gearbox: Bevel gearboxes transmit power between non-parallel shafts. They are commonly used in vehicles, marine applications, and heavy machinery where changing the direction of motion is necessary.
  • Planetary Gearbox: Planetary gearboxes offer high torque density and compact size. They are used in robotics, automation, and precision machinery due to their efficiency and versatility.
  • Worm Gearbox: Worm gearboxes have a worm screw meshing with a gear wheel. They provide high reduction ratios and are used in applications like conveyor systems, elevators, and packaging equipment.
  • Cycloidal Gearbox: Cycloidal gearboxes use cams and pins for motion transmission, making them highly durable and shock-resistant. They find use in industrial machinery and robotics.
  • Spiral Bevel Gearbox: Spiral bevel gearboxes combine the advantages of bevel and helical gears, providing high efficiency and smooth operation. They are employed in vehicles, aircraft, and machine tools.

Each type of gearbox offers specific advantages suited to its application, enabling efficient power transmission and control in various industries.
