Introduction to the main propulsion system of ships - gearbox
Marine diesel generator sets, marine propellers, and gearboxes are equivalent to gearboxes to cars for ships. The changes in the marine gearbox market largely depend on the "climate" of the shipbuilding industry
The gearbox must have sufficient rigidity to withstand the force and torque generated by the wind turbine and the reaction force generated during gear transmission. Marine diesel generators and propellers are used to prevent deformation and ensure transmission quality.
The design of the gearbox body should be based on the requirements of the marine bearing series for wind turbine power transmission, coupling layout arrangement, processing and assembly conditions, and ease of inspection and maintenance.
With the continuous rapid development of the gearbox industry, more and more industries and different enterprises in marine equipment are using gearboxes, and more and more enterprises are growing and expanding in the gearbox industry.
According to the modular design principle of unit structure, the gearbox greatly reduces the types of components for the 30M patrol boat propeller, making it suitable for large-scale production and flexible selection of propellers for 30M patrol boats.
The large engineering ship propeller reducer spiral bevel gear and helical gear are made of high-quality alloy steel carburizing and quenching, with a tooth surface hardness of up to 60 ± 2HRC and a tooth surface grinding accuracy of up to 5-6 levels.
Large bulk cargo propellers and large container propellers - the transmission bearings are selected from well-known domestic brands or imported bearings, and the sealing components are skeleton oil seals; Acoustic box structure, large box surface area, and large fan; Reduce the temperature rise and noise of the whole machine, improve the reliability of operation, and increase the transmission power.
Large engineering ship propellers can achieve parallel axis, orthogonal axis, vertical and horizontal universal box bodies, with input methods including motor connection flanges and shaft input; The output shaft can output at right angles or horizontally, and is equipped with solid shafts, hollow shafts, and flange type output shafts. To meet the installation requirements of narrow spaces, the gearbox can also be supplied according to customer needs.
The volume of marine diesel generator sets is 1/2 smaller than that of soft toothed gearboxes, the weight is reduced by half, the service life is increased by 3-4 times, and the load-bearing capacity is increased by 8-10 times.
Marine diesel generator sets are widely used in printing and packaging machinery, three-dimensional garage equipment, environmental protection machinery, conveying equipment, chemical equipment, metallurgical mining equipment, steel and power equipment, mixing equipment, road construction machinery, sugar industry, wind power generation, escalator and elevator drive, shipbuilding industry, light industry, papermaking industry, metallurgy industry, sewage treatment, building materials industry, lifting machinery, conveyor lines, assembly lines and other high-power, high speed ratio, high torque occasions. Marine propellers have good cost-effectiveness and are conducive to the matching of domestically produced equipment.
