Abstract
The utility model aims at providing an involute initial angle for a static vortex disc of an improved compressor, which belongs to the technical field of a vortex type compressor and can make sure that the difference of phase angles of a dynamic vortex disc and the static vortex disc can be kept 180 DEG under the impact of gas forces so as to lead the dynamic vortex disc to be well meshed with the static vortex disc when in working. The technical key point lies in that the involute initial angle for the static vortex disc is slightly larger than that for the dynamic vortex disc. The involute initial angle for the static vortex disc is slightly larger than that for the dynamic vortex disc; therefore, when the compressor is in normal working, the phase angles of the dynamic vortex disc and the static vortex disc are deviated under the impact of the gas forces, so as to lead the difference of the phase angles to be right 180 DEG, thereby leading the dynamic vortex disc to be well meshed with the static vortex disc when in working, effectively reducing circumferential leakage of the meshing surface, and making sure that the compressor can still maintain high working efficiency after bearing normal abrasion.
Description
Technical field
This patent relates to a kind of improved compressor fixed scroll involute initial angle, belongs to the scroll compressor technical field.
Background technique
The moving scroll of scroll compressor all equates with the design of fixed scroll involute initial angle at present, keep under the situation in gap between circle and the steel ball not considering in the anti-rotation mechanism, the design that this involute initial angle equates can make scroll and fixed scroll phase angle differ 180 °, could mesh preferably and have only when moving scroll and fixed scroll phase angle differ 180 °, but in fact because there is certain tolerance range in anti-rotation mechanism in the process of processing, so moving circle 1 that keeps in the anti-rotation mechanism, certainly exist certain clearance T (as shown in Figure 1) between quiet maintenance circle 2 and the steel ball 3, this gap can make scroll produce little rotation under the effect that is subjected to gas force, make, phase angle between the fixed scroll changes, thereby cause moving scroll and fixed scroll phase angle to differ and be not equal to 180 °, cause moving scroll and fixed scroll when work, can not well mesh, increase the circumferential leakage of Surface of action, reduced the volumetric efficiency of compressor.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provide a kind of and can guarantee that dynamic and static scroll is under the influence that is subjected to gas force, its phase angle still can keep differing 180 ° improved compressor fixed scroll involute initial angle, thereby makes scroll and fixed scroll can be good at engagement when work.
Its technological scheme is: a kind of improved compressor fixed scroll involute initial angle is characterized in that: the angle of described fixed scroll involute initial angle is slightly larger than the angle of moving scroll involute initial angle.
Its technique effect is: because the angle of fixed scroll involute initial angle is slightly larger than the angle of moving scroll involute initial angle, so when the compressor proper functioning, move between scroll and the fixed scroll because of being subjected to the influence of gas force, its phase angle is offset, it is 180 ° just that the two phase angle is differed, thereby make scroll and fixed scroll when work, can be good at engagement, effectively reduced the circumferential leakage of Surface of action, guaranteed that compressor still can keep very high working efficiency after normal wear.

Embodiment
As shown in Figure 2, when the fabrication and processing fixed scroll, suitably increase the angle of fixed scroll 4 involute initial angles, make it be slightly larger than the angle of moving scroll 5 involute initial angles.When the compressor proper functioning, because of being subjected to the influence of gas force, its phase angle is offset between moving scroll and the fixed scroll, and it is 180 ° just that the two phase angle is differed.
