Double-end power taking diesel generating set

Abstract

The invention relates to a double-end power taking diesel generating set, and belongs to the technical field of diesel generators. The double-end power taking diesel generating set comprises a crankshaft, threaded holes at the flywheel end of the crankshaft are fixedly provided with a flywheel body through a high-strength bolt, and the side, away from the crankshaft, of the flywheel body at the flywheel end is fixedly provided with a flywheel ring gear through a bolt. The double-end power taking diesel generating set is characterized in that the free end of the crankshaft is also provided witha flywheel body through a high-strength bolt, the shaft center position between the flywheel body at the free end and the crankshaft is positioned through a positioning stepped shaft, the positioningstepped shaft is installed on a circular ring table at the free end of the crankshaft, and the side, away from the crankshaft, of the flywheel body at the free end is also fixedly provided with a flywheel ring gear through a bolt. According to double-end power taking diesel generating set, the problems that an existing design scheme can only generate electricity through one end of a diesel engine, an electric generator with large power, complex structure and expensive price needs to be installed, then the installation precision requirement is high, and the installation precision is not proneto be guaranteed are solved.

Description

technical field [0001] The invention relates to a double-terminal power-taking diesel generator set, which belongs to the technical field of diesel generators. Background technique [0002] The positioning connection between the diesel engine and the generator of a diesel generator set is very important. Insufficient connection accuracy can easily lead to damage to the connecting thread, generator vibration, and even serious consequences of generator sweeping. The elastic connection shaft of the generator of the existing diesel generator set and the flywheel end of the diesel engine realize precise positioning and connection through the position constraints of multiple contact surfaces. [0003] An invention patent of Zhejiang Kaishan Heavy Industry Co., Ltd. with the publication number CN205805413U mentioned the design scheme of using double-ended power output for the generator: the power transmission is realized through the coupling, one end provides hydraulic power, and t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a double-end power-taking diesel generator set, which adopts the method of connecting the flywheel at both ends of the crankshaft of the diesel engine, and then connects the generator through the flywheel to solve the problem that the existing design scheme can only generate power through one end of the diesel engine, which requires a large installation. Power, complex structure, expensive generator, and high installation accuracy requirements, not easy to guarantee and other issues

At the same time, a special installation and positioning device is designed to solve the problem of precise positioning of the flywheel installed at the free end of the ordinary diesel engine crankshaft
