Claims (1)

[Claims for Utility Model Registration] (1) Each rotor has a reference cylindrical surface, a blade fitting portion that has a depressed portion from the reference cylindrical surface and communicates with the outer circumference of the blade, and the blade fitting portion The rotors, each of which is configured to have a blade protruding from the reference cylindrical surface while being adjacent to the recessed portion, synchronously rotate in opposite directions in a non-interfering state with each other, and the reference cylindrical surface of each rotor It is a rotating machine configured so that the rotors on the hollow body side rotate closely around the fixed hollow body, and the rotor on the hollow body side rotates closely around the fixed hollow body. Focusing on the chamber, during a period in which the minimum volume state of the working chamber is communicated with an intermediate volume state having a predetermined value larger than the minimum volume of the working chamber, the blade fitting portion of the rotor on the hollow body side is connected to the hollow body. In a rotary machine configured to communicate with the hollow body through a communication port formed in the hollow body, focusing on the rotor on the hollow body side, a rotor support shaft is inserted through the rotor while closely surrounding the hollow body. A support structure for a rotor of a rotating machine, characterized in that the rotor is integrally fixed to the inside of a reference cylindrical surface of the rotor, and the rotor is thus supported by a rotor support shaft. (2) Focusing on the blade fitting part of the rotor on the hollow body side, the predetermined wall surface that connects to the outer circumference of the blade forming the blade fitting part is on the hollow body side adjacent to the blade fitting into the blade fitting part. Scope of Utility Model Registration Claim 1: The scope of the utility model registration is created by a portion communicating with the outer periphery of the blade at the tip of the wall surface that communicates with the outer periphery of the blade forming the blade fitting portion of the rotor that meshes with the rotor. The rotor support structure of the described rotating machine. (3) Focus on the blade of the rotor that meshes with the rotor on the hollow body side, and make sure that the side surface of the blade on the back side of the blade fitting part of the blade reaches the reference cylindrical surface of the wall that forms the blade fitting part where the blade fits. A support structure for a rotor of a rotating machine according to claim 2, which is configured to be created by at least a portion of the predetermined portions that communicate with each other. (4) Pay attention to the blade of the rotor that meshes with the rotor on the hollow body side, and make sure that the side surface of the blade on the back side of the blade fitting part of the blade reaches the reference cylindrical surface of the wall that forms the blade fitting part where the same blade fits. 4. A support structure for a rotor of a rotating machine according to claim 3, which is created by a portion communicating with a reference cylindrical surface at a tip end of a predetermined communicating portion. (5) Paying attention to the rotor blade fitting part on the hollow body side, make a relatively large gap between the wall surface forming the blade fitting part and the blade side surface of the blade fitting into the blade fitting part. A rotor support structure for a rotating machine as set forth in claim 1 of the utility model registration claim. (6) Focusing on the blade fitting part of the rotor on the hollow body side, the part facing the blade end surface of the blade fitted into the blade fitting part of the wall surface forming the blade fitting part of the rotor support shaft; A rotor for a rotating machine according to any one of claims 3 to 5 of claims 3 to 5, which is a utility model registration, wherein the gap between the blade fitted in the blade fitting portion and the blade end face is relatively large. supporting structure. (7) Scope of utility model registration claims for a rotating machine in which each rotor has one blade, in which a counterweight is integrally formed on the rotor support shaft, and the counterweight is located inside the rotor. A support structure for a rotor of a rotating machine according to any one of Items 1 to 6. (8) The rotating machine according to any one of claims 1 to 6 of the utility model registration claim, wherein the rotor on the hollow body side has one blade, and the rotor that meshes with the rotor on the hollow body side has one blade. Rotor support structure. (9) The rotating machine according to any one of claims 1 to 6 of the utility model registration claim, wherein the rotor on the hollow body side has two blades, and the rotor that meshes with the rotor on the hollow body side has two blades. Rotor support structure. (10) The rotating machine according to any one of claims 1 to 6, wherein the rotor on the hollow body side has two blades, and the rotor that meshes with the rotor on the hollow body side has one blade.
