Abstract
A system, in one embodiment, may include a chassis, an engine coupled to the chassis, a generator coupled to the engine, and a rotary screw compressor coupled to the chassis independent from the engine. The engine may be configured to drive both the generator and the rotary screw compressor. A method, according to another embodiment, may include isolating a rotary air compressor from an engine and a generator in a common chassis. The isolating may include separately mounting the rotary air compressor and the engine with a resilient or distance adjustable connection in between. The isolating also may include resiliently mounting the engine, or the rotary air compressor, or both.
Claims18
A welding system, comprising:
- a chassis;
- an engine coupled to the chassis;
- a welding generator configured to drive a welding current, the welding generator coupled to the engine;
- a compressor coupled to the chassis independent from the engine, wherein the engine is configured to drive both the welding generator and the compressor;
- and
- a geometrically adjustable coupling disposed between a first shaft of the engine and a second shaft of the compressor, wherein the geometrically adjustable coupling is configured to maintain a connection between the first and second shafts during variations in distance between the first shaft and the second shaft from a first distance to a second distance different from the first distance when the engine is driving the compressor, wherein a third shaft extends from the engine opposite the first shaft to drive the welding generator, and the first shaft and the third shaft form part of a shaft extending through the engine.
A welding system, comprising:
- an engine coupled to a chassis, the engine comprising a first shaft extending from a first side of the engine and a second shaft extending from a second side of the engine opposite the first side;
- a welding generator configured to drive a welding current, the welding generator coupled to the engine;
- a compressor coupled to the chassis independent from the engine, wherein the engine is configured to drive both the welding generator and the compressor;
- and
- an adjustable coupling disposed between the engine and the compressor, the adjustable coupling configured to rotate about the first shaft and a compressor drive shaft coupled to the compressor, wherein the adjustable coupling is configured to maintain a connection between the first shaft and the compressor drive shaft during variations in distance between the first shaft and the compressor drive shaft from a first distance to a second distance different from the first distance when the engine is driving the compressor, and wherein the first shaft extends from the engine toward the compressor and the compressor drive shaft extends from the compressor toward the engine.
