Abstract

The invention relates to the field of gear transmission devices of ship power transmission systems, in particular to a marine gearbox barring and shaft locking device. The marine gearbox barring and shaft locking device comprises a gearbox body and a barring power assembly. A first connecting piece is arranged on an input shaft of the gearbox body, and the output end of the barring power assemblyis movably connected with a second connecting piece in a sleeving manner. The second connecting piece can slide in the axial direction and can be in butt joint with or separated from the first connecting piece, and when the second connecting piece is in butt joint with the first connecting piece, circumferential synchronous rotation is achieved. A locking structure is arranged on the gearbox body,when the second connecting piece is separated from the output end of the barring power assembly, the second connecting piece is in butt joint with the first connecting piece, and the locking structure circumferentially locks the second connecting piece. The marine gearbox barring and shaft locking device integrates functions of barring and shaft locking, and therefore, the problems that barring and shaft locking of an existing ship main propulsion system are controlled in a scattered mode, the efficiency is low, the structure is complex, the cost is high, and operation is complex are solved.

Description

technical field [0001] The invention relates to the field of gear transmission devices of marine power transmission systems, in particular to a crankshaft locking device for a marine gear box. Background technique [0002] The cranking operation of the main propulsion system of the existing ship is controlled by the diesel engine, and the gear box clutch (when the gear box is equipped with a clutch) needs to be in the combined state during cranking, which is inconvenient to operate. The existing diesel engine cranking device has no shaft locking and braking function, and a separate braking device needs to be installed on the shafting. The structure is complex and costly, and the cranking and locking shaft are controlled in two places, which is inconvenient to operate and low in efficiency. [0003] For the prior art, please refer to the following Chinese utility model patent documents, the publication numbers are "CN201516919U", "CN206495720U", "CN206704499U" and "CN20870253...
