Abstract
An electric power generation device includes a genset with an engine coupled to a generator and an enclosure that includes a base having a plurality of bosses protruding upwardly each a respective predetermined height from a surface of the base. A plurality of coil springs is positioned between an upper surface of each of the bosses and a respective mounting member of the genset. The bosses and the mounting members are positioned such that each respective coil spring is approximately equally loaded by the genset.
Claims25
A system, comprising:
- an electric power generating device including an internal combustion engine coupled to an electric power generator, the electric power generating device including three mounting sites;
- a support mechanism to engage the electric power generating device and bear mechanical load thereof, the support mechanism including:
- a base including three support pillars, the support pillars each extending away from the base and each providing a corresponding mount at a predetermined distance from the base;
- and
- three vibration isolation devices each positioned between a respective one of the three mounting sites and the corresponding mount of a respective one of the support pillars, where a reference plane through each of the vibration isolation devices approximately intersects a center of gravity of the electric power generating device.
A method, comprising:
- providing a genset;
- providing a base having a plurality of support members protruding upwardly from a lower portion of said base;
- placing a vibration isolator on top of a respective one of said support members;
- installing said genset to rest on top of said vibration isolators;
- and
- wherein said installing of the genset positions each of the vibration isolators to intersect a reference plane, the reference plane being coincident with a center of gravity of the genset resting on said vibration isolators within a tolerance range.
A method, comprising:
- providing a genset;
- providing a base having a plurality of support members protruding upwardly from a lower portion of said base a predetermined distance;
- placing a coil spring on top of each said support member;
- and
- positioning said genset on top of said coil springs, where said support members are oriented in said base such that each said coil spring is approximately equally loaded by the weight of said genset.
A system, comprising:
- an electric power generating device including at least a portion of an internal combustion engine and an electric power generator mechanically coupled to the internal combustion engine, the electric power generating device including three mounting sites;
- a support mechanism to engage the electric power generating device and bear mechanical load thereof, the support mechanism including:
- a base including three support members, the support members each extending from the base and each providing a corresponding mount;
- and
- three vibration isolation devices each positioned between a respective one of the three mounting sites and the corresponding mount of a respective one of the support members, the vibration isolation devices each bearing a respective portion of the mechanical load of the electric power generating device, the support mechanism being configured to define a plane coincident with a center of gravity of the electric power generating device that passes between the respective one of the mounting sites and the corresponding mount of each of the support members.
