Shaft-holding type shaft-driven generator for a ship

Abstract

The invention provides a shaft-holding type shaft-driven generator for a ship, which comprises a generator body encircling a main shaft, wherein the generator main body includes a stand, a stator core, a rotor, a support plate, a clamping device, a stator coil, an end cover, a motor bracket, an adjustment device, a steel plate base, an end cover connecting device and a stand connecting device, wherein the stand, the stator core, the rotor, the support plate, the tensioning sleeve and the motor end cover are divided into an upper part and a lower part around the main shaft. The shaft-holding type shaft-driven generator does not need to transform the main shaft and reduces the requirements for space limitation on the ship; the motor body removes the bearing, thereby greatly reducing the repair and maintenance cost of vulnerable parts such as the bearing, and reducing the maintenance and repair intensity of workers; the motor rotor and the main shaft are directly connected into an integrated structure, thereby greatly reducing the influence imposed on the motor rotor by deflection of the main shaft; and there is no need to disassemble the motor bracket when the motor is repaired and maintained, and only part of the end cover needs to be removed, so that the assembly and disassembly process is greatly simplified.

Description

technical field [0001] The invention relates to the field of navigators, in particular to a shaft-holding type marine shaft generator. Background technique [0002] On a ship, the main engine generally drives the propeller to sail, and all electrical equipment on the ship is powered by an auxiliary generator, which causes a lot of energy consumption. [0003] At present, there are two main types of marine shaft generators, one is that a transmission shaft is connected to the generator at the free end of the main marine engine; the other is with a main engine gearbox (many ships directly use low-speed diesel engines, Without a reducer) a shaft is drawn out to connect the generator. These two methods have great limitations. One is that the space at the free end is very small and cannot be installed. Even if there is space, it is very difficult to guide the shaft from the free end of the engine, and even affect the reliability of the main engine. The other is that large ships...
