Abstract
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.
