Document Type and Number:
WIPO Patent Application WO/2020/215779
Kind Code:
A1
Abstract:
Disclosed are a crankshaft deformation balance method and device, a crankshaft with balance weights determined according to the method, and a scroll compressor using the crankshaft. The method comprises: determining a centrifugal component force required by each balance weight to overcome the deformation of a crankshaft (9) generated under the combined action of a centrifugal force of a movable plate (6) and a gas force; and determining the balance weights according to the centrifugal component forces, wherein the balance weights are arranged on the crankshaft (9). The method solves the technical problem of the balancing effect in the related art being poor due to only the influence of the centrifugal force of the movable plate on the crankshaft being considered.
