Embodiment Construction

[0017] like figure 1 As shown in the figure, the line segment-arc combined profile is a single scroll tooth profile, which is composed of circular arcs and line segments in turn. One circle of the profile line is composed of 4 arcs and 4 line segments alternately. The center points of the four arcs in the circle are four points A, B, D, and C, that is, the arc part of the entire profile is composed of four groups of concentric arcs, and the center angles of the arcs are all 90°. The four center points of the four arcs form a parallelogram. At the same time, in the 4 groups of line segments constituting the profile line, the lengths of each group of line segments are equal, and the opposite sides of the 4-segment line segments in each circle are equal in pairs. The shape of the spiral tooth formed by the combined profile line is close to a square. The positional relationship between the dynamic and static single scroll teeth formed by the line segment-arc combination profile ...

Abstract

The invention discloses a line section and arc combination line for a scroll compressor, which is formed by combining arcs and line sections in turn. The line section and arc combination line can form a scroll wrap with equal wall thickness and can be used as a single scroll wrap line, a single scroll wrap fully-meshed line, and a double scroll wrap line, and a moving scroll wrap and a static scroll wrap can be meshed correctly during working; and when the line section and arc combination line is used as the single scroll wrap line, a formed single scroll wrap is approximately square. The line section and arc combination line provided by the invention can effectively improve the utilization rate of the area of a scroll, effectively increase the inspiratory capacity of the scroll compressor and the compression ratio under the condition of the same contour dimension of the scroll, and can reduce the contour dimension of the scroll under the condition of the same inspiratory capacity; meanwhile, the formed scroll wrap can increase the area of the central part of a scroll wrap head, contributes to forming of a vent hole with a large area, reduces air exhaust loss and has high comprehensive performance. Further, the line section and arc combination line contributes to improving the performance of the scroll compressor further, and has great significance to the enrichment of the types of the scroll wrap lines and development of the scroll compressor.

Description

technical field [0001] The invention belongs to the technical field of compressors, and particularly relates to a scroll tooth profile of a scroll compressor. Background technique [0002] Scroll compressors are widely developed in the fields of refrigeration, air conditioning and gas transportation due to their remarkable advantages of high volumetric efficiency, high reliability and low vibration and noise. The scroll tooth profile type has always been the key technology of the scroll compressor. The existing scroll tooth profile types mainly include: circular involute, regular polygon involute, parallelogram involute, semicircle eccentric line, line segment Involutes, Archimedes Spirals, Algebraic Spirals, Reduced Base Circle Involutes, Envelope Profiles, and Universal Profiles. With the gradual expansion of the application field of scroll compressors, the types of scroll tooth profiles have also become rich, and many combined profiles have appeared: circular involute-ar...
