Mover offset amount adjusting device, linear motor, and linear compressor

Abstract

The present disclosure relates to the technical field of compressors, and specifically discloses a mover offset adjusting device, a linear motor and a linear compressor. The mover offset adjusting device comprises a sleeve fixed on a plate spring assembly, an adjusting disc fixed on a mover, and a top piece arranged on the sleeve. One end of the top piece extends into a gap between the adjusting disc and the plate spring assembly through a wedge structure. The cross-sectional width of the gap between the adjusting disc and the plate spring assembly is smaller than the maximum width of the cross section of the top piece. The device can control the extension amount of the top piece into the gap between the adjusting disc and the plate spring assembly, so that the adjusting disc and the mover connected thereto can move axially until the mover offset is adjusted to meet the requirements, and then the extension of the top piece is stopped. The sleeve can support the top piece, so that the top piece can complete the extension and extraction work more stably.
