Abstract (en)
A scroll compressor includes a fixed scroll including a fixed scroll wrap, an orbiting scroll including an orbiting scroll wrap, a main shaft including an eccentric shaft portion that is located at a first end of the main shaft and to which the orbiting scroll is attached, a rotary drive unit that rotates the main shaft to cause the orbiting scroll to orbit, a slider provided between the eccentric shaft portion of the main shaft and the orbiting scroll and included in a variable crank mechanism that adjusts a radius of orbital motion of the orbiting scroll, a frame fixed to the fixed scroll and supporting the fixed scroll and the orbiting scroll, and an Oldham ring that is provided between the frame and the orbiting scroll, prevents the orbiting scroll from rotating on an axis of the orbiting scroll, and converts rotational motion of the main shaft into orbital motion of the orbiting scroll. The fixed scroll wrap has a side portion that supports an orbiting-scroll centrifugal force that is a centrifugal force generated by the orbital motion of the orbiting scroll. The Oldham ring performs simple harmonic motion during the orbit of the orbiting scroll. The orbiting scroll orbits in an elliptical orbit having a minor axis and a major axis, and the direction along the minor axis of the orbit of the orbiting scroll coincides with the direction of the simple harmonic motion of the Oldham ring.
