| 38 | Scroll compressor and method of machining scroll lap | US10562446 | 2003-10-24 | US20060159580A1 | 2006-07-20 | Hideaki Matsuhashi |
| By cutting-machining a side face of a scroll wrap with a non-rotational tool, swells in the perimeter direction have a smaller size. Thus, the leakage of compressed gas is prevented from being caused between side faces sliding to each other of the respective wraps of the stationary scroll and the slewing scroll. This configuration provides a scroll compressor that has a higher accuracy by which a high compression efficiency and low noise are realized. | ||||||

| A movable scroll element for a scroll type compressor is produced by a combination of a mold casting process and a machining process. The mold casting process produces a cast product having an end-plate forming portion, a spiral-member-forming portion and a projecting portion for forming a drive power receiving portion. The cast product has an entire outer faces covered with black scale, and the machining process machines the end-plate-forming portion, a spiral member forming portion, the projecting portion by cutting. Nevertheless, at least an outer circumference of the drive power receiving portion, i.e., a boss portion of the movable scroll element is covered with an outermost layer consisting of black scale. Thus, a sufficient mechanical strength of the movable scroll element is obtained even if the wall thickness of the drive power receiving portion, i.e., the boss portion of the movable scroll element, is reduced. | ||||||

| A wrap of an orbiting scroll member and a wrap of a fixed scroll member are each provided with a non-rigid surface coating layer having a predetermined thickness. An orbiting radius varying mechanism is provided between a driving shaft and the orbiting scroll member, thereby gradually increasing the orbiting radius of the orbiting scroll member at the initial stage of running, and thus positively allowing the surface coating layers to wear by rubbing against each other. A stopper mechanism is provided between the driving shaft and the orbiting scroll member to regulate the rotation angle of a variable crank relative to the driving shaft to a predetermined rotation angle, thereby preventing the surface coating layers from being excessively worn as the orbiting radius of the orbiting scroll member increases. | ||||||
