Description

Technical Field

[0001] This utility model relates to the field of generator set technology, and in particular to a vibration-damping generator set common base. Background Technology

[0002] As the core device of modern energy supply systems, generator sets are typically integrated systems composed of a power generation unit (engine) and an energy conversion unit (generator) through mechanical coupling. The engine, acting as the prime mover, performs the primary energy conversion function, transforming various energy sources into transmittable mechanical kinetic energy through internal combustion chemical reactions (diesel / gasoline / natural gas, etc.) or fluid kinetic energy conversion (hydraulic / wind power, etc.). The generator, based on Faraday's law of electromagnetic induction, converts the input rotating mechanical energy into electrical energy through the electromagnetic interaction of the stator-rotor winding system.

[0003] In traditional generator set architectures, the power transmission system typically employs a rigid connection between the engine crankshaft output and the generator rotor input, usually a rigid coupling structure secured by flange bolts. While this design ensures power transmission efficiency, its structural defects become increasingly apparent under conditions of continuously increasing generator power density and operating frequency: First, the rigid connection cannot effectively attenuate the pulsating impacts generated by the engine's periodic bursts of power, leading to high-frequency mechanical resonance in the transmission system; second, with the widespread application of modern generator sets with rated power of 10kW-20kW and operating frequencies exceeding 60Hz, the phenomenon of alternating stress concentration caused by combined vibrations is significantly aggravated, especially at the engine-generator interface where stress peaks are easily formed. Engineering practice shows that under continuous full-load conditions, the vibration acceleration value of traditional structures can reach more than 2.3 times the limit specified in ISO 10816-3, directly causing microcrack propagation in the generator end cover, and in severe cases, brittle fracture accidents.

[0004] Therefore, how to provide a vibration-damping common base for generator sets to improve the connection strength between the engine and the generator and alleviate the vibration generated during generator set operation has become an urgent technical problem to be solved. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a vibration-damping common base for generator sets, thereby improving the connection strength between the engine and the generator and alleviating the vibration generated during generator set operation.

[0006] This utility model is implemented as follows: a vibration-damping generator set common base, comprising:

[0007] A U-shaped steel frame has a first horizontal extension symmetrically arranged outward at both ends, a vertical extension symmetrically arranged upward at both ends, and a second horizontal extension symmetrically arranged outward at the top front end; the first horizontal extension has two first connecting holes; the vertical extension has four second connecting holes; and the second horizontal extension has four third connecting holes.

[0008] A reinforcing rib is fixed at both ends to the left and right sides of the U-shaped steel frame and is located in the middle of the U-shaped steel frame;

[0009] Two support members are symmetrically arranged at the bottom end of the second horizontal extension and are fixedly connected to the second horizontal extension and the U-shaped steel frame.

[0010] A mounting bracket is installed on the outside of one of the vertical extensions;

[0011] Six vibration damping pads are respectively locked to the bottom ends of the first horizontal extension and the second horizontal extension through the first connecting hole and the third connecting hole.

[0012] Furthermore, the mounting bracket is provided with a mounting slot.

[0013] Furthermore, it also includes:

[0014] Six locking accessories are respectively connected to the vibration damping pad through the first connecting hole or the third connecting hole.

[0015] The advantages of this utility model are:

[0016] 1. By incorporating a U-shaped steel frame, reinforcing ribs, supporting components, mounting brackets, and vibration damping pads, the U-shaped steel frame, as an integrated steel frame, effectively enhances strength. It features a first horizontal extension, a vertical extension, and a second horizontal extension. The first horizontal extension has two first connecting holes, the vertical extension has four second connecting holes, and the second horizontal extension has four third connecting holes. The reinforcing ribs are fixed to the left and right sides of the U-shaped steel frame at both ends to further enhance overall strength. Supporting components are located at the bottom of the second horizontal extension to effectively support it. Vibration damping pads are secured to the bottom of the first and second horizontal extensions via the first and third connecting holes, respectively. When the engine and generator are mounted on a common base, the connection strength between them is effectively improved. Vibration during operation is transmitted through the U-shaped steel frame to the vibration damping pads, where it is absorbed and mitigated. This significantly enhances the connection strength between the engine and generator, greatly reduces vibration during generator operation, makes generator operation more stable, and significantly extends the generator's service life.

Detailed Implementation

[0023] This utility model embodiment provides a vibration-damping generator set common base 100, which solves the technical problem in the prior art where the rigid connection between the engine and generator cannot effectively attenuate the pulsating impact generated by the periodic bursts of power from the engine, leading to high-frequency mechanical resonance in the transmission system; as the operating power and operating frequency of the generator set increase, the operating vibration of the entire generator set also increases, which can even lead to the cracking and damage of the end cover at the connection between the generator and the engine in severe cases. It achieves the technical effect of greatly improving the connection strength between the engine and the generator and greatly alleviating the vibration generated during the operation of the generator set.

[0024] The technical solution in this utility model embodiment is to solve the above problems. The overall idea is as follows: an integrated U-shaped steel frame 1 is set to connect the engine 7 and the generator 8, a reinforcing rib 2 is set to improve the strength of the U-shaped steel frame 1, and a vibration damping pad 5 is set at the bottom of the U-shaped steel frame 1 to alleviate vibration, so as to improve the connection strength between the engine 7 and the generator 8 and alleviate the vibration generated when the generator set is working.
