Abstract

The invention provides a movable scroll drive assembly and a scroll compressor. The movable scroll drive assembly includes a main shaft, a tail shaft and an eccentric shaft sleeve, the tail shaft is eccentrically connected to the main shaft, the eccentric shaft sleeve is rotatably sleeved on the tail shaft, and a stop part, the limiting part is set on the tail shaft, the limiting part is provided with the first protrusion of the limiting part, and the eccentric bushing is provided with the first protrusion of the limiting part corresponding to The first groove of the inserted eccentric shaft sleeve, the width of the first groove of the eccentric shaft sleeve is greater than the width of the first protrusion of the limiting part. By setting the limiting part on the tail shaft, a mortise joint structure is provided between the limiting part and the eccentric shaft sleeve, which can limit the circumferential rotation and axial movement of the eccentric shaft sleeve, and the assembly process is simple.

Description

technical field [0001] The invention belongs to the technical field of scroll compressors, and in particular relates to a movable scroll drive assembly and a scroll compressor. Background technique [0002] The orbiting radius of the movable scroll around the fixed scroll changes accordingly, which can achieve a suitable contact force on the movable and fixed scroll teeth in the radial direction, thereby improving the reliability of the scroll compressor. [0003] In the existing dynamic and static scroll structure, a shaft sleeve is usually nested in the drive bearing at the tail of the movable scroll, and a cylindrical hole is eccentrically opened in the shaft sleeve and the supporting part of the drive bearing of the dynamic disk. The drive tail shaft assembled in the hole is arranged eccentrically with the central axis of the main shaft, and the bushing can freely rotate within a certain angle range relative to the drive tail shaft. When the drive motor drives the crank...
