Abstract
Power systems having reduced operating noise and associated methods are disclosed. An example power system includes an engine, a generator, a driveshaft, and a pulley system. The driveshaft may include at least one coupler configured to dampen vibration transferred by the driveshaft. The pulley system may include a first pulley and a second pulley that are drivingly coupled to one another via one or more belts. The generator may be configured to generate electric power using a rotational force received form the engine via the driveshaft and pulley system.
Claims20
A power system comprising:
- a driveshaft;
- an engine configured to output a rotational force and drivingly coupled to the driveshaft to drive the driveshaft;
- a pulley system comprising a first pulley, a second pulley, and one or more belts;
- a generator configured to generate electric power by receiving the rotational force;
- and
- an enclosure, wherein the driveshaft, the engine, and the generator are arranged within the enclosure, wherein:
- the driveshaft is drivingly coupled to the first pulley to drive the first pulley;
- the first pulley is drivingly coupled to the second pulley via the one or more belts to drive the second pulley;
- the generator is drivingly coupled to the second pulley at a first generator side of the generator to drive the generator;
- and
- the generator extends from the first generator side and toward the engine to a second generator side of the generator opposite the first generator side.

A power system comprising:
- a driveshaft;
- an engine configured to output a rotational force and drivingly coupled to the driveshaft to drive the driveshaft;
- a pulley system comprising a first pulley, a second pulley, and one or more belts;
- and
- a generator configured to generate electric power by receiving the rotational force, wherein the generator is mounted to a first base structure and the engine is mounted to a second base structure that is arranged to dampen vibration transfer to the first base structure wherein:
