Embodiment Construction

[0014] The present invention will be described in further detail below with reference to the embodiments of the drawings:

[0015] Such as figure 1 , figure 2 , image 3 with Figure 4 The scroll compressor shown includes a drive shaft 1, a joint assembly mounted on the drive shaft 1, and a needle roller bearing 3. The crank 2 of the drive shaft 1 is connected to the needle bearing 3 through a sleeve 4 of the joint assembly; The hole wall of the shaft sleeve hole has at least one bearing drive plane 5; in the sleeve hole, a section of the crank 2 near the outer end has a crank drive plane 5 that engages with the sleeve drive plane, and the other section of the crank 2 is provided with a shaft sleeve The driving plane 5 preferably has a plane with a gap of 0.3 to 0.5 mm, and the gap value s in this embodiment is 0.5 mm.

[0016] Since the driving plane of the second half of the crank of the drive shaft 1 is lower than the first half, a gap is formed between the driving surface of ...

Abstract

The invention discloses a scroll compressor, relating to the technical field of fluid machinery. The scroll compressor comprises a driving shaft, a joint component installed on the driving shaft, and a needle roller bearing, wherein a crank of the driving shaft is connected with the needle roller bearing through a shaft sleeve of the joint component. The invention is characterized in that the wall of the shaft sleeve hole of the joint component at least has one bearing driving plane; and in the shaft sleeve hole, one section of the crank adjacent to the outer end is provided with a crank driving plane bonded with the shaft sleeve driving plane, and the other section of the crank is provided with a plane which has a 0.3-0.5mm clearance with the shaft sleeve driving plane. Compared with the prior art, the invention can solve the problems of low working reliability, difficulty in assembly, and insufficient operation stability in the existing scroll compressor.

Description

Technical field [0001] The invention relates to the technical field of fluid machinery, in particular to a scroll compressor which is connected to a crank with a drive shaft eccentrically arranged to drive a movable scroll. Background technique [0002] The scroll compressor realizes the compression of the compression medium through the relative meshing movement of the moving and static scrolls. The fixed scroll and the moving scroll mesh with each other to form a moving closed chamber, and the moving scroll wraps around the static scroll. When rotating in parallel, the volume of the closed chamber formed by the stationary and movable scrolls changes from large to small. The center of the stationary scroll is provided with an exhaust port, and the compressed medium is discharged from the exhaust port to realize the vortex. The whole process of rotary compressor suction, compression and discharge. The orbiting scroll of the scroll compressor is connected and driven by a crank ecc...
