Abstract
A vibration dampened power generation aggregate including an internal combustion engine, generator and outlet box mounted upon a frame having vibration dampening mounts for the power generation aggregates. The outlet box as an interior space divided into compartments for the placement of accessories, switches and generator governors. The frame has a first side and a second side and the power generation aggregate is mounted on the frame such that the mass of the power generation aggregate is evenly distributed on the first and second sides to reduce harmonic vibration and sound transmission of the power generation aggregate on the frame during aggregate operation.
Claims14
A vibration dampened power generation aggregate, comprising:
- a frame defining a first side and a second side, said frame comprised of longitudinal members having a length and oriented in a first direction;
- said frame further comprising at least one transverse member extending in a second direction between said longitudinal members;
- said frame supported by frame bearings and equipped with aggregate bearings supported on a vibration dampening material to insulate said aggregate bearings from said frame;
- said aggregate bearings and said frame bearings disposed vertically relative to each other and further equipped with vibration dampening material interposed between said frame bearings and said aggregate bearings;
- and
- a power generation aggregate comprising an internal combustion engine mounted on at least some of said aggregate bearings;
- said engine operable to impart rotary motion to an electrical generator coupled to said engine;
- said generator mounted on at least some of the aggregate bearings;
- and an outlet box having a front panel and back panel in spaced apart relation relative to each other and having opposed sidewall panels extending substantially there between to define an interior space;
- at least one of said outlet panels having a aperture therein to admit at least a part of said generator into said interior space;
- said outlet box mounted on at least some of said aggregate bearings;
- said outlet box interior space further divided into compartments for placement of accessories, switches and governors for the power generation aggregate;
- said power generation aggregate mounted on said frame such that said power generation aggregate has a mass substantially evenly distributed between said first side and said second side along substantially the length of said frame to substantially reduce oscillation and sound transmission of said power generation aggregate on said frame during aggregate operation.
An outlet box for use in a power generation aggregate, comprising a front panel and a back panel in spaced apart relation to each other, opposed side panels in opposition to each other and extending between said front and back panel to define an interior space;
- said front panel equipped with an aperture to admit at least a part of a power generation aggregate to said interior space;
- said side panels further equipped with at lest one compartment for accessories, power switches and governor switches to be positioned in said outlet box such that said outlet box center of mass is evenly distributed along a first side and a second side of a vibration frame;
- said outlet box mounted upon a vibration frame supported by frame bearings and equipped with aggregate bearings supported on a vibration dampening material to insulate said aggregate bearings from said frame;
- said aggregate bearings and said frame bearings disposed vertically relative to each other and further equipped with vibration dampening material interposed between said frame bearings and said aggregate bearings with vibration dampening material interposed between said frame bearings and said aggregate bearings.
