Embodiment Construction

[0045] figure 1 with figure 2 The illustrated oil-free screw compressor 1 comprises a compressor element 2 and a gearbox 3 .

[0046] Such as Figure 4 As shown, the compressor element 2 comprises a housing 4 with two rotor chambers 5 in which screw rotors 6 and 7 (male 6 and female 7 respectively) pass through their respective shafts 8 and 9 Installed on the bearing 10.

[0047] The rotor chamber 5 is sealed by a shaft seal 11 which is attached around the shafts 8 and 9 .

[0048] The housing 4 of the compressor element 2 is provided with a mounting surface 12 via which the compressor element 2 is mounted by bolts or similar not shown means to a corresponding mounting surface 13 of the housing 14 of the gearbox 3 .

[0049] These mounting surfaces 12 and 13 shown in the example are completely flat and extend in a plane transverse to the axial direction of the rotors 6 and 7 .

[0050] The housing 4 of the compressor element is provided with an inlet 15 and an outlet 16...

Abstract

Screw compressor that is composed of a compressor element (2,2') with a housing (4) in which two helical rotors (6,7) are mounted on bearings (10) by their shafts (8,9), and a gearbox (3) with a housing (14) with a mounting surface (13) that is built onto a mounting surface (12) of the housing (4) of the compressor element (2,2'), and which is coupled in a torque-transmitting way to a shaft (8,9) of at least one of the aforementioned rotors (6,7), whereby the compressor element (2) is provided with an oil circuit with an input (34) and an output (35) for oil and a cooling jacket (26) with an input (27) and output (28) for a coolant, characterised in that the aforementioned inputs (27,34) and outputs (28,35) for the oil and for the coolant are located in the aforementioned mounting surface (12) of the housing (4) of the compressor element (2), whereby these inputs (27,34) and outputs (28,35) connect to channels (29) for the respective supply and removal of the oil and the coolant that are at least partially integrated internally in the gearbox (3).

Description

technical field [0001] The invention relates to a screw compressor, a compressor element and a gearbox for the screw compressor. Background technique [0002] Known screw compressors comprise a compressor element mounted to a gearbox. [0003] The compressor element is provided with a housing in which the two screw rotors are mounted via their shafts on bearings lubricated with oil, at the end of the housing the compressor element is provided with an oil passage, the The oil passage has an oil input part and an oil output part. [0004] The compressor element is also provided with a cooling jacket having an input and an output to be able to circulate a coolant through the cooling jacket so as to be able to cool the compressor element. [0005] The gearbox is provided with a housing having a shaft for coupling a motor or other drive means, and the gearbox can be coupled in a torque-transmitting manner with the shaft of at least one aforementioned rotor. [0006] The compre...
