Problems solved by technology

Moreover, the mass of the synchronous main generator is large, and when the synchronous main generator vibrates vertically, it is easy to cause the vibration of the whole locomotive
[0006] 2. There must be a gap of not less than 2mm between the ball head rod assembled by the rubber bearing and the seat hole of the synchronous main generator along the entire radial direction, which cannot buffer the lateral vibration
Unless the amplitude of the lateral vibration is greater than 2mm, the rubber buffer support can buffer the lateral vibration, but it cannot reduce the lateral vibration
Moreover, when synchronizing the lateral vibration of the main generator, it is also easy to cause the shaking of the whole locomotive

Embodiment 1

[0026] Such as figure 1 , figure 2 with image 3 As shown, a synchronous main generator vibration damping structure of a diesel locomotive includes a synchronous main generator 5 and a diesel engine 4 installed on the car body floor 3, one end of the synchronous main generator 5 is fixed on the output end of the diesel engine 4, and the other end is suspended in the air , the side wall of the synchronous main generator 5 and the car body floor 3 are correspondingly provided with a mounting seat 1, and the vertical hydraulic shock absorber 2 is vertically installed between the synchronous main generator 5 and the car body floor 3 through the mounting seat 1, The transverse hydraulic shock absorber 6 is installed horizontally between the synchronous main generator 5 and the vehicle body floor 3 through the mounting base 1 . The shown vertical hydraulic shock absorber 2 and transverse hydraulic shock absorber 6 are respectively installed two on both sides of the synchronous ma...

Embodiment 2

[0032] Such as Figure 4 , Figure 5 with Image 6 As shown, the difference between this embodiment and Embodiment 1 is that two pairs of mounting bases 1 are correspondingly arranged on the side wall of the synchronous main generator 5 and the vehicle body floor 3, and the inclined hydraulic shock absorber 7 is obliquely installed through the mounting bases 1 Between the synchronous main generator 5 and the vehicle body floor 3 . The distance between two adjacent inclined hydraulic shock absorbers 7 is 50mm-1000mm.

[0033] The outer diameter of the hydraulic cylinder of the inclined hydraulic shock absorber 7 is φ30mm˜φ200mm.

[0034] The synchronous main generator 5 adopts traditional rubber bearing assembly for vibration reduction, which can only buffer vertical vibration. However, the inclined hydraulic shock absorber 7 of this embodiment can absorb the vibration energy of the synchronous main generator 5 , which can reduce the vertical vibration of the synchronous ma...

Abstract

The invention discloses a synchronous main generator vibration attenuation structure for an internal combustion locomotive. The synchronous main generator vibration attenuation structure comprises a synchronous main generator and a diesel engine, wherein the diesel engine is arranged on a bottom plate of a locomotive body; one end of the synchronous main generator is fixed at the output end of the diesel engine, and the other end of the synchronous main generator is suspended; and hydraulic vibration attenuation devices are symmetrically arranged on the two sides of the synchronous main generator. By virtue of the vibration attenuation resistance property of the hydraulic vibration attenuation devices, the synchronous main generator vibration attenuation structure can be used for alleviating vertical and transverse high-frequency and low-frequency vibration of the synchronous main generator so as to alleviate the vibration of the locomotive, eliminating untimely fatigue of structure intensity of mechanical parts including the synchronous main generator, the diesel engine, the locomotive body and the like, prolonging the service life of the locomotive, and improving the comfort of trainmen.

Description

technical field [0001] The invention relates to a vibration damping structure, in particular to a vibration damping structure of a synchronous main generator of a diesel locomotive. Background technique [0002] At present, one end of the synchronous main generator of a diesel locomotive is fixed at the output end of the diesel engine, and the other end is suspended in the air. Due to the unbalanced weight of the rotor, the rotor rotates when the synchronous main generator is working, which will cause vibration, and the mass of the synchronous main generator rotor is relatively large (about 2000kg), so the vibration force is not easy to eliminate. At the same time, when the diesel engine is working, vibration will also be generated, and the vibration will be transmitted to the rotor through the coupling, resulting in increased vibration of the synchronous main generator, and even the vibration of the entire locomotive. The current traditional method is to use rubber bearing...
