Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shaft generator, in particular to a cooling type shaft generator for ship. BACKGROUND

[0002] The shaft generator is a kind of power generation equipment directly driven by the crankshaft of ship main engine or vehicle engine, and is widely used in large ships, train locomotives and other mobile platforms powered by large internal combustion engines. For the shaft generator on the ship, it is mainly connected with the propeller shaft of the ship main engine through a mechanical transmission device, and relies on a gear box to solve the mismatching problem of the main engine shaft and the generator in terms of speed, direction and power transmission demand. Part of the mechanical energy output by the main engine is converted into electrical energy to stably power the ship's power grid system.

[0003] When the traditional shaft generator is installed, the assembled generator is lifted into the ship cabin by lifting equipment, and then fixed on the base pre-installed in the cabin by bolts and other connecting parts. Therefore, during installation or maintenance, the bolts need to be repeatedly aligned and tightened, which is low in installation efficiency. Since the layout between the generator parts is compact, it is not convenient to use tools to tighten the bolts. Moreover, the generator will continuously vibrate at high frequency during operation, which may cause the bolts and nuts to loosen, resulting in poor firmness.

[0004] The generator is usually fixed on the base by bolts during installation. Due to the continuous high-frequency vibration caused by the operation of the ship main engine, the ship's shaft generator shaft system may be offset, and the bolts of the associated equipment such as the gear box may be loose. Therefore, a large elastic coupling is usually arranged between the shaft and the main engine shaft. If the vibration is directly transmitted to the generator mounting base, the base may be cracked and damaged, which is poor in practicability.

[0005] When connecting the generator shaft and the shaft of the gear box, a coupling is usually used for fixation. Therefore, when there is a slight deviation between the diameter of the shaft and the inner diameter of the coupling, it is difficult to accurately adapt. If forced fixation is used, it may cause loosening. Therefore, it is usually necessary to replace the adapted coupling, which is complicated in operation process, low in installation efficiency and poor in flexibility. SUMMARY
