Abstract

PURPOSE:To easily perform maintenance and inspection work without causing the necessity for disassembly of a motor, by forming a crankshaft rotated with the motor of a turning scroll meshed to a fixed scroll to a hollow shape and fitting a motor shaft to this hollow part. CONSTITUTION:A fixed scroll 1 is fixed to a compressor casing 6 by bolts 11, further a turnings croll 2 is supported with a boss part 2a to the point end part of a crankshaft 3 through a bearing 4. Here the crankshaft 3 is partially or fully formed to a hollow shape, and the point end part of a motor shaft 9 is fitted to this hollow part 3a while the both sahfts 3, 9 are integrally combined by a bolt 12. In this way, the bolts 11 are removed to separate said both scrolls 1, 2 from the casing 6, then the bolt 12 is removed to separate said both shafts 3, 9, further bolts 7 are removed to separate the casing 6 from a motor casing 5, thus maintenance and inspection work for bearings 4, 14, etc. can be easily performed.
