A bearing structure for a screw rotary machine, characterized in that the male and female rotors are arranged to restrict movement of the male and female rotors in the axial direction. (2) In a screw rotary machine in which the working space volume changes while moving in the axial direction due to meshing rotation of a pair of male and female screw rotors, the low pressure end of the rotor is acted on from the high pressure end to the low pressure end. A tapered roller bearing is provided to support the thrust force, and a flanged roller bearing is provided on the high-pressure end side of the rotor to restrict axial movement of the rotor in the direction opposite to the thrust force. The inner end of the inner race of the bearing is brought into direct contact with the step on the rotor shaft side, while the outer end of the outer race is fixed to the casing via an adjustment plate to restrict movement in the axial direction of the rotor. Bearing structure of screw rotating machine.
