Clutch component of gearbox for high-power ship

Abstract

The invention relates to a clutch component of a gearbox for a high-power ship. The clutch component comprises an elastic torsion shaft, a hollow shaft gear, a clutch base, a clutch and an oil cylinder shaft, the elastic torsion shaft is connected with the hollow shaft gear, the elastic torsion shaft is supported on a clutch flange through a bearing, the elastic torsion shaft is connected with the clutch base, and the clutch comprises the clutch base, the clutch flange, a clutch shell gear and the oil cylinder shaft, and the clutch flange, the clutch shell gear and the oil cylinder shaft are connected into a whole through bolts. The clutch component is good in overall robustness and stable in structure, unbalance loading of the bearing and the gears is reduced, the additional dynamic load of the clutch is reduced, the service life of the bearing, the gears and a friction plate of the clutch component is prolonged, the service life of the gearbox is prolonged, and the maintenance cost of the gearbox is reduced. Through optimization of all parameters, the size of the gearbox is reduced, and the power density of the gearbox is improved.

Description

technical field [0001] The invention relates to the field of marine gear boxes, in particular to a clutch component of a high-power marine gear box. Background technique [0002] The service life of large ships is generally 15 to 20 years, and some even reach 30 years. The design life of thousands of hours of use. The low actual service life is usually due to design, manufacture, and improper use. The actual situation is that the service life of the gearbox is far from reaching the service life of the ship. [0003] The clutch parts of the GWC series of large marine gearboxes are supported by bearings after the clutch is connected to the row, which is a super-static structure, and there are 4 bearings arranged on the same axis. After the factory test of the bearing rollers of the bearings at both ends of the shaft gear of the clutch component, the proportion of obvious damage marks on the rollers is relatively high, especially the damage of the gearbox with the higher powe...

Problems solved by technology

[0006] At the same time, there are many models of large diesel engines, and the number of ships is limited. Due to the small number of manufactured gearboxes for large ships, they are produced in small batches, which often leads to low power density of gearboxes and high manufacturing costs, so an optimized design must be carried out.
