As shown in figure 4,41 tooth of the first scroll wrap height is H1 (the hereinafter referred to as high H1 of tooth).Due to being got over sealing strip 3
Close to the center of the first scroll wrap 41, the influence of suffered pressure and temperature is bigger, and the deformation quantity of sealing strip 3 is also bigger, institute
To reserve enough axial deformation spaces.
(that is: 51 length of low-pressure area is the first scroll wrap 41 in the region division mode of preferred first scroll wrap 41 as an example
The 1/2 of total length, middle 52 length of pressure area are the 3/10 of 41 total length of the first scroll wrap, and 53 length of higher-pressure region is the first scroll wrap 41
The 1/5 of total length), high to 41 tooth of the first scroll wrap at any point in each area, 3 thickness of transverse tooth thickness and corresponding position sealing strip meter

(1) through repeated measurement and test, inventors have found that total deformation quantity of each subregion scroll wrap 4 is initial value
One thousandth, if a height of original tooth of the original tooth of low-pressure area 51 is high, then terminal (the i.e. low-pressure area 51 and middle pressure area 52 of low-pressure area 51
Junction) the high height of tooth is the 99.9% of original tooth high height;The terminal tooth height of middle pressure area 52 is 51 terminal of low-pressure area
The 99.9% of tooth high height, and so on.
(2) the high H1 of the tooth of low-pressure area 51 is integrally in homogenous linear downward trend, the slope a of entire lowering are as follows: (original tooth is high
The 99.9%- of height original tooth height)/low-pressure area 51 length;Wherein, 51 length of low-pressure area is the total arc of the first scroll wrap 41
Long 1/2;So the original tooth height/0.5 total arc length of a=0.001.If the radian of A point is X, low-pressure area starting point radian is X ';A
The tooth of point height is Y, and the high height of 51 starting point tooth of low-pressure area is Y '.So there is equation: a (X-X ')=Y-Y ', a is i.e. above
The slope found out.Because X '=0, Y ' are that original tooth is high, reasoning can obtain the high calculation formula of above-mentioned A point tooth.Following middle pressures
The calculation formula of the high H1 of tooth at any point in area 52 and higher-pressure region 53, the calculation formula of transverse tooth thickness H2 and each area's sealing strip in each area
