Automatic centering system, engine test bed system and centering method

Abstract

The invention discloses an automatic centering system, an engine test bed system and a centering method. The centering system comprises a non-contact transmission device, a centering monitoring device and a centering adjusting device. The non-contact transmission device can realize non-contact transmission between a diesel engine and a dynamometer; the centering monitoring device is used for acquiring a centering deviation value; and the centering adjusting device can automatically adjust the position of a base according to the centering deviation value. The requirement for centering precision of a diesel engine power module can be lowered, the centering state of the diesel engine power module can be monitored and adjusted in real time, and harm caused by overload is avoided.

Description

technical field [0001] The invention relates to the technical field of engine testing, in particular to an automatic centering system, an engine test bench system and a centering method. Background technique [0002] As is known, the marine diesel engine propulsion power module is mainly composed of single or multiple diesel engines, gearboxes, couplings, shaft motors and other equipment. The shafting is an important part of the propulsion power module of the marine diesel engine, and the normal operation of the shafting guarantees the ship's navigation. The misalignment of the shafting system will affect the transmission efficiency of the power plant, and will also cause problems such as wear of parts, vibration and noise. The coupling accuracy of the transmission shaft has gradually become an extremely important evaluation index in the assembly of power machinery. Improving the alignment accuracy is an important means to prevent failures of rotating equipment such as engi...

AI Technical Summary

Problems solved by technology

[0003] However, in the process of building a diesel engine platform test, the shafting of the diesel engine is time-consuming and labor-intensive, which not only increases the workload of the test personnel, but also increases the difficulty of the test platform construction

Even if a laser alignment tool is used for shaft alignment, differences in input dimensions or measurement positions will cause errors in measurement results

[0004] In addition, the existing diesel engine test bench also faces problems such as long test bench construction period, inability to detect the alignment state of the power module in real time, and easy damage to the diesel engine and transmission shaft due to overload.
