FLUID MACHINE
Document Type and Number:
Japanese Patent JP2014134155
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid machine capable of transmitting large torque by using magnet couplings, and preventing leakage.SOLUTION: An fluid machine includes: an input shaft 41 rotated by power from a motor; a plurality of input side rotation shafts 42 to which rotations of the input shaft 41 are transmitted, and rotating; a plurality of output side rotation shafts 44 to which rotations of the plurality of input side rotation shafts 42 are respectively transmitted, and rotating; a plurality of magnet couplings 43 having an input side magnet 61 provided on each input side rotation shaft 42 and an output side magnet 62 provided on each output side rotation shaft 44, and capable of coupling each input side rotation shaft 42 and each output side rotation shaft 44 without contacting; an output shaft 45 to which rotations of the plurality of output side rotation shaft 44 are transmitted, and rotating; a rotor to which rotations of the output shaft 45 are transmitted, and rotating to make a fluid flow; and a casing for hermetically storing the plurality of output side magnets 62, a plurality of output side rotation shafts 44, the output shaft 45, and the rotor.
