The vortex processing method of scroll compressor of the present invention, the structure of its compressor structure with shown in Figure 5 generally speaking are identical, thereby description this paper of its structure and running is omitted.Distinguish as depicted in figs. 1 and 2 and process processing method static and the revolution scroll member.
In Fig. 1 and Fig. 2, sequence number 1 expression stationary scroll element, sequence number 1a is a scrollwork, sequence number 1b represents the top end surface of scrollwork, sequence number 1c is a top board, sequence number 1d represents the bottom surface of passage, and sequence number 1e is an end surfaces, sequence number 2 expression revolution scroll members, sequence number 2a is a scrollwork, sequence number 2b is the top end surface of scrollwork, and sequence number 2c represents an end plate, and sequence number 3 expressions one a polishing emery wheel or a superfinish emery wheel.
When processing or producing stationary scroll element 1 shown in Figure 1, utilize the side surface of conventional end mill milling scrollwork 1a as shown in Figure 6, promptly form the bottom surface 1d of volute and the described passage of milling, subsequently, milling wrap tip surface 1b and with the continuous excircle end portion end face 1e of this wrap tip surface 1b, these steps are implemented under with same clamping condition.Afterwards, this workpiece (that is, the stationary scroll element 1 in the course of working) will remain under this clamp position, utilize emery wheel or superfinish emery wheel to process in the following manner:
(1) to the bottom surface 1d of described passage see off smooth poliss or superfinish polishing processing, then, emery wheel 3 moves in direction shown in the arrow of numerical control lower edge; With
(2) subsequently, according to their mutual size, described wrap tip surface 1b and end surfaces 1e are carried out effective smooth poliss or superfinish.
Similarly, when as shown in Figure 2 revolution scroll member 2 of processing, the end mill that utilizes conventional art as shown in Figure 7 to adopt, the side surface of the described scrollwork 2a of milling and the surface of end plate 2c, then the top end surface 2b of milling scrollwork.These steps are finished under same clamping condition.Then, this workpiece (that is, the revolution scroll member 2 in the course of working), under the above-mentioned clamping condition of maintenance, process in the following manner with described emery wheel or superfinish emery wheel 3:

(2) then, according to its size that is associated, surface 2b carries out effective smooth poliss or superfinish to described wrap tip.
As a result, with traditional only comparing with the surface of end mill processing, accurately machined surface accuracy of aforesaid way or surface condition, promptly surface roughness is greatly improved.
Owing to prepared above-mentioned machining tool, or even, no matter the stationary scroll element 1 or the scroll member 2 that revolves round the sun are processed with above-mentioned processing method, compare with conventional art, can both reduce friction factor largely, its reason is that the surface accuracy on one of slide relative surface of above-mentioned two scroll members is improved.
Stationary scroll element 1 and revolution scroll member 2 according to said process processing of the present invention in use, can obtain the condition that the contact surface shown in Fig. 3 A, 3B, 4A and 4B cooperates.

Fig. 4 A schematically shows the slidingsurface of described scroll member 1 and 2, and the two all passes through superfinish, has reached the example that cooperatively interacts after the surface accuracy preferably.
Or rather, through superfinish, its surface characteristics is to no longer include needle-like on it or the aciculiform bump exists, and therefore, will can not take place such as the interlock at the needle-like bump of end mill finished surface and lapped face.
The situation that the schematically illustrated described slidingsurfaces static and revolution scroll member 1 and 2 of Fig. 4 B mutually combine.One of them slidingsurface is through superfinish, and another is then processed through end mill.
Even this situation is equally also owing to through the surface accuracy on superlinishing surface and the effect of surface condition, can reduce the engagement or the interlock of slidingsurface effectively.
According to embodiment and since with traditional relatively poor acicular surface that only is processed to form with end mill in conjunction with comparing, can obtain the combination of the slidingsurface of the surface accuracy of the fewer jog of formed tool and surface condition.So described friction ractor can greatly reduce, and damage being avoided of bringing, be not worn harmful adverse effect of material powder with the reliability that causes compressor than galling with substrate material by the surface of conventional end mill processing.
As a result, form described pump part, can obtain very high mechanical movement efficient, but also realize the high reliability of described scroll compressor because of the static and revolution scroll member that above-mentioned scroll member processes.When the room air conditioner running of this kind compressor is housed, can reduce power consumption to refrigerator or air conditioner widely, therefore realize the saving electric energy, and can realize purpose safe and reliable under the high efficiency operating condition.
According to describing in detail more than the present invention, improve the surface accuracy and the surface condition of scroll member slide relative contact surface part, reduced frictional resistance thus, and reduced the power consumption in the running thus, simultaneously can reach high efficiency again, thereby improve the reliability of scroll compressor.
