Problems solved by technology

[0005] At present, the coaxiality requirements of each component can only be guaranteed by improving the machining accuracy, but when each component is connected, due to the existence of cumulative processing tolerances, it is uncertain whether the overall coaxiality can meet the requirements

Abstract

The invention discloses a diesel generating set assembling coaxiality detection method comprising the following steps: adjusting the position of a rotor connecting flange of a main generator to make the rotor connecting flange concentric with a housing mounting end face of the main generator; then measuring the distance between the mounting end face of the shell of the main generator at different positions in the circumferential direction and the mounting end face of the rotor connecting flange of the main generator, and calculating an inclined included angle between the mounting end face of the rotor connecting flange and the mounting end face of the shell based on the distance; the method is used as a coaxiality evaluation standard of the rotor connecting flange and the main generator shell mounting surface. Under the condition that the main generator rotor does not need to be rotated, the center of the end face of the rotor connecting flange is aligned with the center of the end face of the main generator shell, and then the distance relation between the four points evenly distributed on the end face of the rotor connecting flange and the corresponding four points on the end face of the main generator shell is measured; therefore, the coaxiality of the rotor connecting flange and the mounting surface of the main generator shell is judged.

Description

technical field [0001] The invention relates to the technical field of assembly of diesel generator sets, in particular to a method for detecting the assembly coaxiality of diesel generator sets. Background technique [0002] When the main generator is supported by a single bearing and assembled with the diesel engine, the rotor of the main generator is connected to the flywheel of the diesel engine, and the stator of the main generator is connected to the flywheel housing of the diesel engine. There is no adjustment and alignment during the assembly process, and the coaxiality of the entire unit depends entirely on Machining accuracy guaranteed. For example, the coaxiality of the rotor and stator of the main generator is guaranteed by the machining accuracy of each component. Although the processing accuracy of each connecting part can meet the requirements, such as the coaxiality requirement, it is uncertain whether the coaxiality requirement can be met after each part is...
