摘要： A scroll compressor includes a compression mechanism, a crankshaft, upper and lower bearings, and a drive motor. The compression mechanism includes fixed and movable scrolls engaged with each other to form a compression chamber. The crankshaft has a main shaft and an eccentric portion eccentrically disposed at one end of the main shaft and coupled to a back side of the movable scroll. The upper and lower bearings support upper and lower portions of the main shaft. The drive motor has a stator and a rotor coupled to the main shaft to rotate the movable scroll. At least one of the main shaft and the rotor is provided with a weight arranged to reduce distortion of the crankshaft caused by a fluid load generated in the compression chamber and applied to the eccentric portion during rotation.

摘要： The invention reduces a centrifugal force of a orbiting scroll which acts on an auxiliary crank mechanism. A crank pin which is eccentric from a main shaft portion is formed in a drive shaft, and a main balance weight is provided in a base end side of the crank pin. The main shaft portion of the drive shaft is rotatably supported by using a main bearing, and the crank pin is attached to a orbiting bearing which is provided in a back face side of a orbiting scroll. Further, an internal gap of the main bearing is set to a value which is larger than a value obtained by subtracting the double value of an eccentric amount difference between an eccentric amount of an auxiliary crank shaft and an eccentric amount of the drive shaft from an internal gap of the orbiting bearing. Accordingly, the internal gap of the main bearing does not come to 0 even if a compressor comes to a steady state.
摘要翻译：本发明减小作用在辅助曲柄机构上的绕动涡卷的离心力。在驱动轴上形成有与主轴部偏心的曲柄销，在曲柄销的基端侧设置有主平衡重。驱动轴的主轴部分通过使用主轴承可旋转地支撑，曲柄销安装在设置在绕动涡卷的背面侧的绕动轴承上。此外，主轴承的内部间隙被设定为大于通过从辅助曲轴的偏心量和驱动轴的偏心量之间减去偏心量差的双倍值而获得的值轨道轴承的内部间隙。因此，即使压缩机处于稳定状态，主轴承的内部间隙也不会变为0。

摘要： A second frame is arranged between a first frame and an orbiting scroll, and a central space and an outer peripheral space are sealed off by a seal portion, which is formed between an end surface of a shaft support of the orbiting scroll and the second frame. Also, a balance weight is arranged in a space between an underside of the second frame and the first frame. Thereby, most of an oil having lubricated respective shaft supports flows into the space below the second frame, and the oil accumulated in the space is discharged through an oil scavenge pipe into an oil reservoir in a lower portion of a closed vessel. Also, since the balance weight can be assembled from a side of the orbiting scroll in a state, in which the second frame is removed, it is possible to mount the balance weight close to the orbiting scroll.

摘要： The twin screw rotors for axis-parallel installation in displacement machines for compressible media have asymmetrical transverse profiles and numbers of wraps that are null2. Depending upon the wrapping angle (null), the pitch (L) varies, which pitch increases in a first subdivision (T1) from the suction-side screw end, reaches a maximal value (Lmax) after one wrap, decreases in a second subdivision (T2) until a minimal value (Lmin), and is constant in a third subdivision (T3). The pitch course in the first subdivision (T1) is preferably mirror-symmetrical to that in the second subdivision (T2), within the subdivisions T1 to T2, it is point-symmetrical to the mean values in almost all cases. Compact screw rotors, completely free of imbalance, can thereby be achieved with compression rates of 1.0 . . . 10.0, also without profile variation. Such rotors offer the best prerequisites for reduction in energy requirements, temperature, construction size, costs, as well as for free selection of working materials in applications in chemistry, pharmacy, packaging, and semiconductor technology.
