Screw compressors and compressor elements and gearboxes utilized by screw compressors

摘要

Compressor element (2, 2 ') with a housing (4) in which two helical rotors (6, 7) are housed attached to bearings (10) by their rotor shafts (8, 9) ) And at least one shaft (8, 9) of the helical rotors (6, 7) in a torque transmitting manner and assembled to the mounting surface (12) of the housing (4) of the compressor element (2, 2 ') ) And a gear box (3) with a housing (14) having a mounting surface (13) coupled to the compressor element (2), the input for oil ( 34. Oil and cooling in a screw compressor comprising an oil circuit with 34) and an output (35) and a cooling jacket (26) with an input (27) and an output (28) for the coolant Medicinal The input (27, 34) and the output (28, 35) are arranged in the mounting surface (12) of the housing (4) of the compressor element (2), the input (27, 34) and the output (28, 35). 35) is characterized in that it is connected at least partially integrated inside the gearbox (3) to a channel (29) for the respective supply and extraction of oil and coolant. Screw compressor to do. [Selection] Figure 1
