Compressor with stably translational dynamic scroll

Abstract

This invention is moving scroll stable translation compressor. It includes scroll seat, moving scroll and spacing ring. The scroll seat has a ring wall. The moving scroll is set on the end face of ring wall. Two first sliding rails, which match each other, extend in X axis radial direction on spacing ring. Two second sliding rails, which match each other, extend outwards in Y axis on the surface of scroll seat at back of spacing ring. The ring wall of scroll seat has two matched X axis grooves, which two side walls are buried with many rollers. The two second sliding rails of moving scroll matched spacing ring, are arranged with two matched Y axis grooves. The moving scroll undertakes two-dimensional eccentric operating relative to scroll seat. The roller makes the two-dimensional translational movement of moving scroll, spacing ring and scroll seat smoother. It reduces the resistance and the loss between moving and static scroll walls. Thus, it keeps the compressing function of compressor.

Description

technical field [0001] The invention relates to a compressor with stable translation of movable scroll. Background technique [0002] As shown in FIG. 6 , it is a two-dimensional movable scroll translation mechanism of an existing compressor, which mainly includes a generally elliptical limiting ring 7 , a scroll seat 8 and a movable scroll 9 . Wherein, the ring portion 71 of the limiting ring 7 has two first sliding rails 72 corresponding to each other extending radially, and two second sliding rails corresponding to each other extending outward on one end surface of the ring portion 71 of the limiting ring 7 73, so that the axes of the two first slide rails 72 and the axes of the two second slide rails 73 are perpendicular to each other, and the ring wall 81 of the scroll seat 8 is radially recessed with two corresponding X-axis grooves 82 , for the two first slide rails 72 of the limit ring 7 to slide in the two X-axis grooves 82 of the scroll seat 8, and can be used for...

Problems solved by technology

[0003] However, the above-mentioned spacer ring 7, scroll seat 8 and movable scroll 9 perform eccentric movement in the form of surface contact. After long-term use, the contact surfaces between the three will be worn and a gap will be generated, resulting in the movement of the movable scroll 9. Shaking during action, deviating from the original predetermined travel path range, causing the movable scroll 9 and the static scroll (not shown in the figure) to collide and damage each other's scroll walls, reduce the rated pressure, and lose the original compression function
