Abstract

The invention relates to a double-speed twin-engine incoporation marine gearbox with reverse. The double-speed twin-engine incoporation marine gearbox is mainly composed of a box body component, a hydraulic control and lubricating cooling component, an output component, two intermediate shaft components, two forward first gear clutch components, two forward second gear clutch components and two reverse gear clutch components, wherein the two intermediate shaft components, the two forward first gear clutch components, the two forward second gear clutch components and the two reverse gear clutch components are symmetrically arranged according to an output axis, each clutch component is composed of a clutch shaft, a driving pinion, a wet friction pair, a clutch piston and a clutch housing gear, each wet friction pair is formed in a way that an outer friction plate group and an inner friction plate group are mutually staggered and assembled, and all outer friction plates are connected with the clutch housing gears through splines; forward first gear driving pinions of the forward first gear clutch components, reverse gear driving pinions of the reverse gear clutch components and forward second gear driving pinions of the forward second gear clutch components are respectively engaged with driven big gears of the intermediate shaft components, and coaxial pinions of the intermediate shaft components are engaged with an output big gear of the output component.

Description

technical field [0001] The invention relates to a marine gearbox with two speeds (two forward gears) and reverse (reverse gear), and belongs to the technical field of marine power transmission. Background technique [0002] As the main propulsion device of the ship, the marine gearbox with double engines is driven by two main engines (diesel engines or electric motors) and the load is the propeller. The same type of marine gearboxes for double-engine parallel vehicles are available. The propellers basically use variable torque propellers. Therefore, in addition to the basic functions of double-machine parallel vehicles (power confluence), the gearboxes only have the functions of deceleration, torque increase and clutch, without reverse rotation. (forward / reverse) function, the reverse function is usually realized by the variable torque propeller. [0003] If the fixed-pitch propeller is used, and according to the design conditions, it is required to realize the multi-speed ...
