Abstract
A drive system for a multistage screw compressor with a first compressor stage with a first main rotor mounted on a first shaft in a torque-proof manner and a second compressor stage with a second main rotor mounted on a second shaft in a torque-proof manner. The drive system has a drive shaft for driving the shafts of both main rotors of the first and second compressor stages, wherein the driving of the shaft of the first main rotor takes place independently of the driving of the shaft of the second main rotor, so that the rotational speeds of the two main rotors can preferably be adapted independently of one another.

A drive system for a multistage screw compressor comprising:
- a housing including a housing cavity, a fluid inlet and a fluid outlet;
- a first compressor stage including a first shaft defining a first shaft axis, the first shaft including a first output pinion;
- a second compressor stage including a second shaft defining a second shaft axis parallel to the first shaft axis, the second shaft including a second output pinion and;
- a drive shaft including a first drive wheel and a second drive wheel, the first drive wheel configured to engage with the first output pinion and the second drive wheel configured to engage with the second output pinion;
- wherein toothing between the first drive wheel and the first output pinion are disposed at an angle α from the first shaft axis, and toothing between the second drive wheel and the second output pinion are disposed at an angle β from the second shaft axis, and wherein angles α and β have inverse signs.
A screw compressor comprising:
- a housing including a housing cavity, a fluid inlet, and a fluid outlet;
- a first compressor stage including a first shaft defining a first shaft axis, the first shaft including a first output pinion;
- a second compressor stage including a second shaft defining a second shaft axis parallel to the first shaft axis, the second shaft including a second output pinion, and;
- a drive system for driving the screw compressor, the drive system including:
- a drive shaft including a first drive when and a second drive wheel, the first drive wheel configured to engage with the first output pinion and the second drive wheel configured to engage with the second output pinion;
- wherein toothing between the first drive wheel and the first pinion are disposed at an angle α from the first shaft axis, and toothing between the second drive wheel and the second output pinion are disposed at an angle β from the second shaft axis, and wherein angles α and β have inverse signs.
An oil-injected screw compressor comprising:
- a housing including a housing cavity, a fluid inlet, and a fluid outlet;
- a first compressor stage including a first shaft defining a first shaft axis, the first shaft including a first output pinion;
- a second compressor stage including a second shaft defining a second shaft axis parallel to the first shaft axis, the second shaft including a second output pinion, and;
- a drive system for driving the screw compressor, the drive system including:
- a drive shaft including a first drive when and a second drive wheel, the first drive wheel configured to engage with the first output pinion and the second drive wheel configured to engage with the second output pinion;
- wherein toothing between the first drive wheel and the first pinion are disposed at an angle α from the first shaft axis, and toothing between the second drive wheel and the second output pinion are disposed at an angle β from the second shaft axis, and wherein angles α and β have inverse signs.
