Embodiment 1
[0014] As shown in the figure, the vibration-reducing diesel generator of this embodiment includes a bracket 1 and a diesel generator, and the diesel generator is formed by connecting a diesel engine 2 and a generator 3 through a transmission mechanism; the key is that the diesel engine 2 and The generators 3 are arranged up and down, and are respectively suspended on the support 1 by springs 4; the diesel engine 2 is provided with a first eccentric wheel 21 connected to the crankshaft, and the generator 3 is provided with a The second eccentric 31 , the centroids of the first eccentric 21 and the second eccentric 31 (the position of the black dot in the figure) move in opposite directions in the vertical direction.
[0015] The bottom of the support 1 is provided with an elastic pad 11 to reduce the vibration transmitted from the support 1 to the ground.
[0016] The sides around the bracket 1 are provided with horizontal elastic rods 5, the vibration of the elastic rods 5 wi...

The invention aims at providing a vibration reducing diesel generator. Vibration and noise of a diesel generator can be reduced. The vibration reducing diesel generator comprises supports and a diesel generator body, and the diesel generator body is formed in the mode that a diesel engine and a generator are connected through a transmission mechanism; the diesel engine and the generator are arranged up and down and fixed to the supports respectively; the diesel engine is provided with a first eccentric wheel connected with a crankshaft, the generator is provided with a second eccentric wheel connected with a rotating shaft of the generator, and the moving direction of the mass center of the first eccentric wheel and the moving direction of the mass center of the second eccentric wheel are opposite in the vertical direction. When the diesel generator works, the diesel engine and the generator both generate vibration, and the vibration is mainly caused by rotation of the crankshaft of the diesel engine and rotation of the rotating shaft of the generator; as the moving direction of the mass center of the first eccentric wheel and the moving direction of the mass center of the second eccentric wheel are opposite in the vertical direction, most vertical vibration of the diesel engine and most vertical vibration of the generator can be offset, and the vibration reducing effect is achieved accordingly.
Description
technical field [0001] The invention belongs to the technical field of diesel generators, and in particular relates to vibration reduction diesel generators. Background technique [0002] Diesel generator is a small power generation equipment. It refers to the power machinery that uses diesel oil as fuel and diesel engine as the prime mover to drive the generator to generate electricity. It is generally a single structure, supported on the ground by a metal bracket, and does not have a vibration-damping seat. and other components for vibration reduction. When the diesel generator is working, it will generate large vibration and noise, which seriously affects the comfort of the working environment. Contents of the invention [0003] The purpose of the present invention is to propose a vibration-reduction diesel generator to reduce the vibration and noise of the diesel generator. [0004] The vibration-damping diesel generator of the present invention includes a bracket an...
