Abstract
Proposed is a single screw compressor having an independent mechanical rotational force transmission unit between a rotation shaft of a main screw and a rotation shaft of a star wheel. The rotational force transmission unit has the same transfer ratio as a rotation ratio at which the main screw and the star wheel mesh with each other. The rotational force transmission unit may include: a first gear which is a double-enveloping worm that is fixed to the rotation shaft of the main screw to integrally rotate with the main screw and has the same pitch and lead with the main screw; and a worm gear configured to cooperate with the double-enveloping worm.
Claims9
A single screw compressor comprising a main screw and a pair of star wheels configured to mesh with the main screw to compress a fluid,
- the single screw compressor further comprising a mechanical rotational force transmission unit disposed between a rotation shaft of one of the pair of star wheels and a rotation shaft of the main screw of the single screw compressor and configured to allow the one of the pair of star wheels to rotate synchronously with the main screw without direct contact between the main screw and the one of the pair of star wheels.
