Abstract
A crankshaft is to be provided that allows its assembly process to be simplified, work hours required for the assembly process to be shortened and a manufacturing cost to be reduced. The crankshaft is provided with first eccentric section and second eccentric section at respective ends while interposing a shaft section therebetween and has such a shape that a peripheral edge of the first eccentric section and/or the second eccentric section is positioned radially inside of a peripheral edge of the shaft section.
Claims11
A crankshaft provided with first and second eccentric sections at respective ends while interposing a shaft section therebetween and having such a shape that a peripheral edge of the first/second eccentric section is positioned radially inside of a peripheral edge of the shaft section.
A fluid machine comprising an electric motor driving a crankshaft provided with first and second eccentric sections at each end thereof while interposing a shaft section therebetween within a closed housing, and
- a compression mechanism or a expansion mechanism is driven by the crankshaft through the first eccentric section and the compression mechanism or the expansion mechanism is driven by the crankshaft through the second eccentric section;
- wherein
- the first/second eccentric section has such a shape that their peripheral edge is positioned radially inside of a peripheral edge of the shaft section.
A fluid machine comprising an electric motor driving a crankshaft provided with first and second eccentric sections at each end thereof interposing a shaft section within a closed housing;
- and
- a compression mechanism or an expansion mechanism is driven by the crankshaft through the first eccentric section and the compression mechanism or the expansion mechanism is driven by the crankshaft through the second eccentric section;
- wherein
- a motor rotor that composes the electric motor and that is attached to the shaft section has a partial structure divided along a turning axial line of the shaft section.
