Problems solved by technology

[0002] At present, most of the existing generator set starting systems use air motor starting systems. The starting motor is generally installed on the side of the engine body and meshed with the flywheel. The air motor starting system requires high-pressure air, and the fluctuation of air pressure will affect the instability of the engine start. thereby affecting the performance of the engine

Embodiment Construction

[0019] The generator starting system includes an engine base 7, an elastic coupling 8, three sets of starter motors 1, and a relay control box (not shown in the figure) for controlling the starter motor 1 .

[0020] Such as figure 1 As shown, the three starter motors 1 are installed on the engine base 7 through the motor support 2, wherein two groups of starter motors 1 form an angle of 60° with the central axis of the flywheel of the elastic coupling 8, and the other group of starter motors 1 is located below the center of the flywheel of the elastic coupling 8, the gears of each starter motor 1 mesh with the flywheel of the elastic coupling 8,

[0021] Preferably, each motor support 2 is fixed on the engine base 7 by 10 M20 high-strength bolts.

[0022] Preferably, in order to increase the rigidity of the motor support 2, the motor support 2 adopts an all-steel welded V-shaped structure, and the middle is designed as a semicircular structure. The diameter of the semicircle ...

Abstract

The invention provides a generator set start system which comprises an engine base, an elastic coupling, three start motor sets and a relay control box. The relay control box and the three start motor sets are arranged on the engine base through motor supports. The two motor sets and the center of a flywheel of the elastic coupling form 60-degree angles, and the other motor set is perpendicular to the portion below the center of the flywheel of the elastic coupling. Gears of all the start motors are meshed with the flywheel of the elastic coupling. The generator set start system is stable to start, convenient to operate, high in manufacturability and maintainability and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of generator starting, and in particular relates to a generator starting system. Background technique [0002] At present, most of the existing starting systems of generator sets use the air motor starting system. The starter motor is generally installed on the side of the engine body and meshed with the flywheel. The air motor starting system needs high-pressure air, and the fluctuation of air pressure will affect the instability of the engine start. Thereby affecting the performance of the engine. The air motor is installed on both sides of the engine, which increases the width of the generator set. This starting method puts forward higher requirements for the compact box-type generator set. Contents of the invention [0003] In order to solve the above problems, the present invention provides a generator starting system, which includes an engine base and an elastic coupling, and is characterized in tha...
