Scroll compressor having a compliant frame and a guide frame for the orbiting scroll

A scroll compressor comprising:

• a fixed scroll provided in a hermetic container, having a spiral blade on a seat;
• an orbiting scroll provided in the hermetic container, having a spiral blade on a seat, where the spiral blade of the orbiting scroll forms a compression chamber by being together with the spiral blade of the fixed scroll;
• a motor provided in the hermetic container, having a stator and a rotor for giving a rotation force to a main shaft which drives the orbiting scroll;
• a compliant frame provided in the hermetic container, having a thrust bearing for supporting the orbiting scroll in an axial direction, a main bearing for supporting the main shaft in a radial direction, and two contact surfaces which independently exist, that is a first fitting surface and a second fitting surface, on an external circumference of the compliant frame;
• a guide frame provided in the hermetic container, having two contact surfaces which independently exist, that is a first fitting surface and a second fitting surface, on an internal circumference of the guide frame, which are formed to be contacted with each of the two contact surfaces of the compliant frame, and the guide frame supporting the compliant frame in the radial direction at the two contact surfaces;
• a first space existing at a first contact part where the first fitting surface of the guide frame contacts with the first fitting surface of the compliant frame;
• and
• a second space existing at a second contact part where the second fitting surface of the guide frame contacts with the second fitting surface of the compliant frame,
• wherein at least one of the first space and the second space is set to be equal to or shorter than a space being a length difference between an external diameter of the rotor and an internal diameter of the stator.

• an orbiting scroll provided in the hermetic container, having a spiral blade on a seat, where the spiral blade of the orbiting scroll forms a compression chamber by being together with the spiral blade of the fixed scroll;
• a motor provided in the hermetic container, having a rotor connected to a main shaft for rotating the orbiting scroll and a stator for giving a rotation force to the rotor;
• a compliant frame provided in the hermetic container, having a thrust bearing for supporting the orbiting scroll in an axial direction and a main bearing for supporting the main shaft in a radial direction which rotates the orbiting scroll;
• a guide frame provided in the hermetic container, having a contact surface which contacts with a contact surface of the compliant frame, for supporting the compliant frame by contacting the contact surface of the guide frame with the contact surface of the compliant frame;
• and
• a reamer pin provided in the hermetic container, having two ends one of which is inserted in a reamer hole located close to the contact surface and provided in at least one of the compliant frame and the guide frame, for preventing a rotation of the compliant frame by being contacted with the other of the compliant frame and the guide frame, and the reamer pin having a space between the reamer pin and the reamer hole at a contact part where the reamer pin contacts with the reamer hole,
• wherein the space between the reamer pin and the reamer hole at the contact part is set to be longer than a space between the contact surface of the guide frame and the contact surface of the compliant frame.
