Abstract
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
The invention belongs to diesel generator technical field, be specifically related to vibration damping diesel generator.
Background technique
Diesel generator is a kind of small power generation equipment, to mean with diesel oil etc. as fuel, take diesel engine as the dynamic power machine of prime mover drive electrical generators generating, be generally monomer structure, be supported on ground by Steel Support, does not have the parts for vibration damping such as vibration proof mounting.During diesel generator work, larger vibration and noise can be produced, have a strong impact on the travelling comfort of working environment.
Summary of the invention
The object of the invention is to propose a kind of vibration damping diesel generator, to reduce vibration and the noise of diesel generator.
Vibration damping diesel generator of the present invention comprises support and diesel generator, and described diesel generator is connected by driving mechanism with generator by diesel engine and forms; Key is that described diesel engine and generator are in being arranged above and below and being individually fixed on support; Described diesel engine is provided with the first eccentric wheel be connected with bent axle, and described generator is provided with the second eccentric wheel be connected with alternator shaft, and described first eccentric wheel, the second eccentric barycenter moving direction are in vertical direction contrary.
When diesel generator works, diesel engine and generator all can produce vibration, this vibration mainly crank rotation of diesel engine and the axis of rotation of generator causes, because the first eccentric wheel, the second eccentric barycenter moving direction are in vertical direction contrary, the vertical vibration of diesel engine and generator can be balanced out major part, thus realize vibration damping.
Further, the bottom of described support is provided with cushion, to reduce the vibration that support transmits earthward.
Further, the sidepiece of described support is provided with the flexible rod of level, and the vibration of this flexible rod can lag behind support, thus forms a resistance to the double vibrations of support, absorption portion vibrational energy.
Further, described diesel engine and generator are respectively by spring suspended on support, and this spring can absorb the level of diesel engine and generator and the vibration of Vertical direction, improves effectiveness in vibration suppression.
The vertical vibration of diesel engine and generator is balanced out major part by two eccentric wheels by vibration damping diesel generator of the present invention, thus reduces noise, has extraordinary effect of vibration and noise reduction.

Embodiment 1:
As shown in the figure, the vibration damping diesel generator of the present embodiment comprises support 1 and diesel generator, and described diesel generator is connected by driving mechanism with generator 3 by diesel engine 2 and forms; Key is that described diesel engine 2 and generator 3 are in being arranged above and below, and is suspended on support 1 respectively by spring 4; Described diesel engine 2 is provided with the first eccentric wheel 21 be connected with bent axle, described generator 3 is provided with the second eccentric wheel 31 be connected with generator 3 rotating shaft, and barycenter (in the figure stain position) moving direction in vertical direction of described first eccentric wheel 21, second eccentric wheel 31 is contrary.
The bottom of support 1 is provided with cushion 11, to reduce the vibration that support 1 transmits earthward.
The sidepiece of support 1 surrounding is provided with the flexible rod 5 of level, and the vibration of this flexible rod 5 can lag behind support 1, thus forms a resistance to the double vibrations of support 1, absorption portion vibrational energy.
Above-mentioned spring 4 can absorb the level of diesel engine 2 and generator 3 and the vibration of Vertical direction, improves effectiveness in vibration suppression.
When diesel generator 3 works, diesel engine 2 and generator 3 all can produce vibration, this vibration mainly crank rotation of diesel engine 2 and the axis of rotation of generator 3 causes, because the barycenter moving direction in vertical direction of the first eccentric wheel 21, second eccentric wheel 31 is contrary, the vertical vibration of diesel engine 2 and generator 3 can be balanced out major part, thus realize vibration damping.
