COMPRESSOR, COMPRESSOR FRAME AND PROCESS OF MANUFACTURE OF COMPRESSOR FRAME

摘要

PROBLEM TO BE SOLVED: To provide a compressor frame showing a performance balance between a light-weight characteristic and a high resistance.SOLUTION: A frame 10 of a compressor 1 in accordance with the preferred embodiment of this invention comprises at least one compression chamber 101 for compressing gas sucked into the frame, and comprises a metal-resin complex 16. The metal-resin complex 16 has a resin member 14 with a thickness dand a metal member 12 with a thickness dthat are laminated and connected to each other. A test piece with a ratio of d/dof 3 has a bending fatigue rigidity with no peeling and no breakage when the first state in which the resin member 14 is arranged on the two supporting blocks with its exposed surface being faced upward and no stress is applied and the second state in which one point bending stress of 140 MPa is applied at the central part of a surface of the resin member 14 in a thickness direction and its central part is sunk from the first state are repeated alternatively by 100 million times at a frequency of 30 Hz at a temperature condition of 25°C.
