A kind of auxiliary equipment for starting low-speed marine diesel engine

Abstract

The invention relates to an auxiliary device for starting a marine low-speed diesel engine, belonging to the technical field of marine diesel engine starting devices, comprising a pneumatic motor, an air inlet pipe, a driving rod and a gear. A set of support rings, the lower ends of the middle and rear groups of support rings are provided with a first shock absorbing device, the lower end of the front end support ring is provided with a second shock absorbing device, one side of the second shock absorbing device is provided with a lubricating device, and the second shock absorbing device is provided on one side of the second shock absorbing device. The damping device drives the lubricating device to discharge oil when damping. Compared with the prior art, the first shock absorbing device and the second shock absorbing device are provided to buffer the two groups of interaction forces in the front and rear directions, reduce the generation of vibration, and do not affect the connection stability. , The vibration generated by the compressed air drives the lubricating oil to drip between the flywheel and the gear of the diesel engine, which plays a lubricating role and accelerates the start of the diesel engine.

Description

technical field [0001] The invention belongs to the technical field of marine diesel engine starting devices, in particular to an auxiliary device used for starting a marine low-speed diesel engine. Background technique [0002] Air motors are widely used in marine diesel engines because of their large starting torque, high reliability, low failure rate and strong adaptability. The air motor drives the flywheel of the diesel engine to rotate by converting the pressure energy of the compressed air into rotational mechanical energy, thereby enabling the diesel engine to start. [0003] The existing air motor has certain problems in use. The air motor is fixed on the support frame of the diesel engine, and the compressed air enters the air motor from the air pipe, and there is a process in which the pressure energy of the compressed air is converted into rotating mechanical energy. A large impact force will cause a large vibration to the support frame of the diesel engine, aff...

AI Technical Summary

Problems solved by technology

[0003] There are certain problems in the use of existing air motors. The air motor is fixed on the support frame of the diesel engine. Compressed air enters the interior of the air motor from the air pipe. There is a problem in the process of converting the pressure energy of the compressed air into rotational mechanical energy. A large impact force will cause a large vibration to the support frame of the diesel engine and affect the connection stability. In addition, during the start-up process of the air motor, it usually needs to enter the compressed air multiple times, which will cause a considerable degree of vibration
