Problems solved by technology

Calibrating a marine gearbox is not only time-consuming and laborious, but also requires special tools and professionals with professional skills to operate. If the installation position of the marine gearbox is poorly aligned, not only the vibration of the marine It will cause damage to the gear box mounting bracket, box rupture and other safety and quality accidents that directly affect the use of the gear box

Abstract

The invention discloses a connection device, and particularly relates to a connection device and a connection method of a marine gearbox and a diesel engine. The connection device comprises the diesel engine and the marine gearbox, which are connected through an intermediate flange; a flywheel is arranged between the intermediate flange and the diesel engine; an annular gear is arranged between the intermediate flange and the marine gearbox, and is fixedly connected with the marine gearbox through a tooth-type high-elastic coupling; and a propeller is mounted on the outer side of the marine gearbox. The connection device and the connection method have the advantages that the structure is compact, the dismounting and the mounting are convenient, the use is convenient, and the usability is improved.

Description

technical field [0001] The invention relates to a coupling device, in particular to a coupling device and a coupling method of a marine gear box and a diesel engine. Background technique [0002] At present, rubber block toothed couplings or toothed rubber high elastic couplings are commonly used to connect marine gearboxes and diesel engine flywheels. When connecting rubber block toothed couplings and toothed rubber high elastic couplings Part of it is connected with the input flange of the gearbox, and the aluminum alloy inner ring gear is connected with the flywheel of the diesel engine. The effective tooth width of the aluminum alloy inner ring gear is generally only slightly longer than the teeth of the rubber elastic body, generally less than 10mm. After the aluminum alloy inner ring gear is connected to the flywheel of the diesel engine, there is only a small slip space in the axial direction, and it cannot be disassembled without moving the marine gearbox, while the ...
