Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0050] The present embodiment adopts Cartesian coordinate system to carry out design operation;

[0051] Such as figure 1 The scroll includes the initial arc AC at the center of the scroll, and the outer wall of the scroll is an outer end point A that is tangent to the initial arc AC from the center of the scroll and extends outward. Composite curve AR; the inner wall of the scroll is an inner composite curve CL that is tangent to the inner end point C of the initial arc AC at the center of the scroll and extends outward;

[0052] The starting arc equation is: (x-5.108) 2 +(y-7.819) 2 =12.5 mm, the initial radius of the arc is 3.5 mm; the coordinates of the outer end point A of the initial arc AC are: x=8.1391 mm, y=9.569 mm; the coordinates of the inner end point C of the initial arc AC are: x=5.2482 mm, y=4.322 mm;

[0053] The outer compound curve consists...

Abstract

The invention discloses a scroll disc, which relates to the technical field of scroll compressor manufacturing, comprising that the starting end of the scroll disc center is a starting circular arc, and the outer wall of the scroll disc is the arc starting from the scroll disc center. The outer compound curve is tangent to the outer end point of the initial arc and extends outward; the inner wall of the scroll is an inner compound curve tangent to the inner end point of the initial arc at the center of the scroll disc and extends outward. Compared with the prior art, the present invention can solve the problems of large leakage and high heating temperature of the existing scroll disk.

Description

technical field [0001] The invention relates to the technical field of scroll compressor manufacture, in particular to a scroll disc used for a scroll compressor. Background technique [0002] The core component of the scroll compressor is the scroll, and the scroll is provided with a scroll formed by a curved surface connected by an involute; the working principle of the scroll compressor is composed of two dynamic and static scrolls with scrolls. The scrolls mesh with each other to form at least one pair of crescent-shaped volume chambers to realize the process of fluid suction-compression or expansion-discharge; therefore, the manufacturing accuracy of the scroll profile of the scroll directly affects the performance of the scroll compressor. There is a vortex, the profile of the vortex is an involute profile composed of an analytical curve, since the involute profile is composed of an analytical curve, the cross section of the formed scroll is equal; this There are the ...
