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.
Claims21
A power system comprising:
- a driveshaft having at least one coupler configured to dampen vibration transferred by the driveshaft;
- an engine configured to output, to the driveshaft, a rotational force;
- a pulley system having a first pulley and a second pulley that are drivingly coupled to one another via one or more belts,
- wherein the driveshaft is coupled to the first pulley and configured to drive the first pulley, and
- wherein the first pulley is configured to drive the second pulley via the one or more belts;
- and
- a generator configured to generate electric power, wherein the generator is coupled to the second pulley and configured to receive the rotational force.
A method for operating a power system, the method comprising:
- outputting, via an engine, a rotational force to a driveshaft, wherein the driveshaft comprises at least one coupler configured to dampen vibration transferred by the driveshaft;
- receiving the rotational force at a first pulley of a pulley system;
- transferring, via one or more belts, the rotational force from the first pulley to a second pulley of the pulley system, wherein the first pulley and a second pulley that are drivingly coupled to one another at a fixed pulley ratio;
- receiving, at a generator, the rotational force from the second pulley;
- and
- generating, via the generator, electric power.
A power system comprising:
- a driveshaft having at least one coupler configured to dampen vibration transferred by the driveshaft;
- an engine configured to output, to the driveshaft, a rotational force;
- a pulley system having a first pulley and a second pulley that are drivingly coupled to one another via one or more belts,
- wherein the driveshaft is coupled to the first pulley and configured to drive the first pulley via the at least one coupler;
- a generator configured to generate electric power, wherein the generator is coupled to the second pulley and configured to receive the rotational force;
- and
- a welding-type power supply coupled to the generator and configured to output a welding current.
