The disclosure of simplified the utility model, is hereinafter described the component and setting of specific examples.Certainly, they are only and show
Example, and purpose does not lie in limitation the utility model.In addition, the utility model can in different examples repeat reference numerals
And/or letter.This repetition is for purposes of simplicity and clarity, itself not indicate discussed various embodiments and/or set
Relation between putting.In addition, various specific techniques and the example of material that the utility model provides, but this area is common
Technical staff can be appreciated that the applicable property of other techniques and/or the use of other materials.
In the following, scroll wrap of the description according to the utility model embodiment.
According to the scroll wrap of the utility model embodiment, the fixed scroll of screw compressor can be not only processed, may be used also
To process the motion vortex disk of screw compressor.Specifically, the flute profile line of scroll wrap includes：Lateral line segment, medial type line segment
And SMIC molded line section.
Lateral line segment and medial type line segment are helix, and medial type line segment is located at the inner side of lateral line segment.Here,
It is understood that " lateral line segment ", the concept of " medial type line segment " are well known to the skilled person, therefore only join
Briefly introduce according to the motion vortex disk shown in Fig. 1.In addition, " helix " as described herein is two-dimensional helical line.
As shown in Figure 1, two stripe shape line segments are extended spirally according to same hour hands (such as counterclockwise shown in Fig. 1) direction,
Turned over same at angle, wherein the point on a stripe shape line segment (such as curved section 11 shown in Fig. 1) is (such as shown in Fig. 1
XOuter 1Point and XOuter 2Point) and coordinate origin X0The distance between be consistently greater than another stripe shape line segment (such as the curve shown in Fig. 1
Section 12) on point (such as the X shown in Fig. 1Interior 1Point and XInterior 2Point) and coordinate origin X0The distance between (e.g., XOuter 1X0＞ XIt is interior 1X0、XOuter 2X0＞ XInterior 2X0), then " a wherein stripe shape line segment " is lateral line segment, and " another stripe shape line segment " is medial type line segment.
SMIC molded line section is formed by connecting by multiple circular arcs are tangent successively, the both ends of SMIC molded line section respectively with lateral line segment
Core end and medial type line segment the tangent connection in core end.That is, SMIC molded line section is connected in turn by multiple circular arcs
And often connected two circular arcs are tangent is connected, and one end of SMIC molded line section with the core end of lateral line segment is tangent is connected, separately
One end with the core end of medial type line segment is tangent is connected.Thus, the core of scroll wrap is not only easy to process, and the core of scroll wrap
Portion's wall thickness can be readily available raising.
It is understood that the quantity of tangent arc can be set according to actual requirement in SMIC molded line section, with preferably
Meet actual requirement, for example, can use five sections (as shown in Figure 1 and Figure 2), six sections, seven sections, four sections, three sections etc..In addition, can
With understanding, " core end " refers to the spiral starting point end of helix, its opposite one end is " tail end ", i.e., helix is spiral
End point end.In addition, " wall thickness " or " thickness " of scroll wrap as described herein refers to the thickness obtained by graphing method, i.e.,
Certain point crossed on the outside molded line of scroll wrap does a tangent line, then does the vertical line of the tangent line, the intersection point of the vertical line and inner side molded line
The distance between above-mentioned point of contact is " wall thickness " or " thickness " at this, such as d1, d2 shown in Fig. 1 represent corresponding positions
Put place's " wall thickness " or " thickness ".
Thus, by the way that scroll wrap is processed as above-mentioned form, the difficulty of processing of scroll wrap can not only be reduced, and can be with
The core wall thickness of scroll wrap is effectively improved, in this way, when setting the screw compressor operating of such a scroll wrap, even if scroll wrap
Core bears larger pressure and temperature rise, but remains to keep good shape invariance shape, and then effectively improves two vortexs
Contact wear between disk so that reliability of the compressor in the case where running at high speed greatly improves.And improve be vortexed by doing so
The shape of tooth, without the back lash between two scroll plates of increase, and then effectively improves internal leakage problem, improves whirlpool
Revolve the overall performance of compressor.
Alternatively, the thickness of the tooth wall limited between lateral line segment and medial type line segment is along from core end to tail end
Direction (such as counter clockwise direction shown in Fig. 1) is gradually reduced (" thickness ", " core end ", the explanation of " tail end " are as detailed above),
In this way, the thickness of scroll wrap not only core is thicker, and against the hand of spiral (such as clockwise direction shown in Fig. 1), whirlpool
The trend of progressive additive can be integrally presented in the wall thickness of rotation tooth.Thus, it is possible to preferably tackle in screw compressor operation process
The pressure and temperature rise change of scroll wrap, further improve the deformation of scroll wrap, improve the reliability and pressure of screw compressor
Contracting performance.
Preferably, lateral line segment and medial type line segment are algebraic Archimedes helix line.Thus, it is possible to simple and have
Effect ground ensure the thickness of tooth wall that is limited between lateral line segment and medial type line segment along the direction from core end to tail end by
It is decrescence small, so as to reduce production difficulty, improve production efficiency.
Further, the algebraically Archimedes of the algebraic Archimedes helix linear system number of lateral line segment and medial type line segment
Equal helix coefficient is α0, the algebraic Archimedes helix linear index of lateral line segment and the algebraically A Ji of medial type line segment
The equal spiral linear index of Mead is K0And K0＜ 1, the algebraic Archimedes helix line revolution-radius and medial type of lateral line segment
The equal algebraic Archimedes helix line revolution-radius of line segment is ξ0, referring for example to hereafter equation F1 and equation F2, Yi Jifang
Journey F3 and equation F4.Thus, it is possible to further ensure that the thickness of the tooth wall limited between lateral line segment and medial type line segment
It is gradually reduced along the direction from core end to tail end, and can further reduces production difficulty.
Yet further, it is (such as described below to include the first cylindrical segmental arc tangent with lateral line segment for SMIC molded line section
The first arc section AE and the 6th arc section IM), the second cylindrical segmental arc tangent with the first cylindrical segmental arc it is (such as described below
Second arc section EF and the 7th arc section MN) and the first tangent inner circle segmental arc of medial type line segment (such as the described below the 5th
Arc section HC and the tenth arc section PK) and the second tangent inner circle segmental arc of the first inner circle segmental arc (such as the described below the 4th circle
Segmental arc GH and the 9th arc section OP).
Wherein, the radius R of the first cylindrical segmental arc1wWith the first inner circle segmental arc R1nRadius meet relation：R1n=R1w+2ξ0
(such as R described below5=R1+ 2* ξ and R10=R6+ 2* ξ), the radius R of the second cylindrical segmental arc2wWith the second inner circle segmental arc R2n's
Radius meets relation：R2n=R2w+2ξ0(such as R described below4=R2+ 2* ξ and R9=R7+2*ξ)。
Thus, the shape of SMIC molded line section is optimized by doing so so that the first inner circle segmental arc and the second inner circle segmental arc can be with
Participate in compression work simultaneously improve the core thickness of scroll wrap so that further increase the core of scroll wrap functional reliability and
The overall performance of compressor.In addition, by doing so optimize SMIC molded line section shape, can with it is ingenious avoid fixed scroll and
Movement interference problem occurs for the core of motion vortex disk.
