Abstract
A positive-displacement fluid machine with a constrained gear set is provided. The positive-displacement fluid machine includes multiple shafts including a single drive shaft and multiple idler shafts. Multiple lobed rotors are provided with each mounted for rotation on one of the shafts. Each lobed rotor of the multiple of lobed rotors meshes with at least two other lobed rotors of the multiple of lobed rotors. A constrained gear set includes multiple timing gears. Each of the multiple timing gears is mounted for rotation on one of the multiple shafts. Each timing gear of the multiple timing gears intermeshes with at least two other timing gears of the multiple timing gears.
Claims20
A positive-displacement fluid machine, comprising:
- a compressor chamber including multiple fluid inlets and multiple fluid outlets;
- a gear chamber;
- a plurality of shafts spanning the compressor chamber and the gear chamber, wherein the plurality of shafts includes:
- a drive shaft, and
- multiple idler shafts;
- a plurality of lobed rotors housed in the compressor chamber, each of the plurality of lobed rotors being mounted for rotation on one of the plurality of shafts;
- and
- a constrained gear set housed in the gear chamber, the constrained gear set including a plurality of timing gears, each of the plurality of timing gears being mounted for rotation on one of the plurality of shafts, wherein each timing gear in the plurality of timing gears intermeshes with at least two other timing gears of the plurality of timing gears.
An assembly for a fluid machine, comprising:
- a plurality of shafts including a drive shaft and multiple idler shafts;
- a plurality of lobed rotors, each of the plurality of lobed rotors being mounted for rotation on one of the plurality of shafts, wherein each lobed rotor of the plurality of lobed rotors meshes with at least two other lobed rotors of the plurality of lobed rotors;
- and
- a constrained gear set, the constrained gear set including a plurality of timing gears, each of the plurality of timing gears being mounted for rotation on one of the plurality of shafts, wherein each timing gear of the plurality of timing gears intermeshes with at least two other timing gears of the plurality of timing gears.
