Title:
UNIAXIAL ECCENTRIC SCREW PUMP
Document Type and Number:
Japanese Patent JP2023132373
Kind Code:
A
Abstract:
To provide a uniaxial eccentric screw pump capable of coupling a coupling shaft to at least one shaft body of a rotor and a driving machine while suppressing the deviation of an axis position, and capable of smoothly releasing the coupling.SOLUTION: In a uniaxial eccentric screw pump 10, at least either one of a drive side coupling portion 100 and a rotor side coupling portion 200 are disassemblably coupled with each other while fitting structures 180 and 280 are formed by first shaft coupling portions 110 and 210 provided on a first shaft forming one of two shafts to be connected, and second coupling portions 150 and 250 provided on a second shaft forming the other. The uniaxial eccentric screw pump 10 is equipped with a coupling bolt 170 for releasing the fitting structures 180 and 280, and a non-fastening screw hole 118b for providing the coupling bolt 170.SELECTED DRAWING: Figure 1
