摘要： Disclosed are a method and a device for balancing crankshaft deformation e, a crankshaft with counterweights determined according to the method, and a scroll compressor using the crankshaft. The method includes: determining a component centrifugal force required by a counterweight to overcome the crankshaft deformation caused by both an orbiting scroll centrifugal force and a gas force; and determining the counterweight according to the component centrifugal force. The counterweight is arranged on the crankshaft.

摘要： An orbiting scroll plate driving assembly provided by the present application includes a main shaft (7), a tail driving shaft (6), and an eccentric shaft sleeve (5). The tail driving shaft (6) is eccentrically connected to the main shaft (7), and the eccentric shaft sleeve (5) is rotatably sleeved on the tail driving shaft (6). The orbiting scroll plate driving assembly further includes a limiting portion (14). The limiting portion (14) is disposed on the tail driving shaft (6), and provided with a first limiting portion protrusion (141). The eccentric shaft sleeve (5) is provided with an eccentric shaft sleeve groove (51). The first limiting portion protrusion (141) is correspondingly inserted into the eccentric shaft sleeve groove. A circumferential size of the eccentric shaft sleeve groove (51) is larger than a circumferential size of the first limiting portion protrusion (141). By providing the limiting portion (14) on the tail driving shaft (6), and providing a mortise joint structure between the limiting portion (14) and the eccentric shaft sleeve (5), the circumferential movement and axial movement of the eccentric shaft sleeve (5) can be confined, and the assembly and processing are simple. Further, a scroll compressor is disclosed.
