Description of the new type: [Technical field to which the new type belongs] This creation relates to a concave structure of the thrust surface of a compressor, which is formed in particular by forming a concave surface in the thrust surface of a scroll under support to promote the establishment of a lubricant film . [Prior art] In the conventional scroll compressor, since it has many moving parts, and friction occurs between the moving parts, the top mask of the support seat supporting the lower scroll has a thrust surface for A bottom end surface provided with the lower scroll is attached to the thrust surface. Generally, in this type of scroll compressor, the thrust surface of the scroll under its support has grooves. However, these grooves are only designed to guide the lubricating oil into the thrust surface. It does not consider the plane size and The effect of depth on the fluid power of the lubricating oil leads to the inability of the lubricating oil introduced into the thrust surface to form a good oil film distribution, which results in poor lubricating effect and makes it easy to shorten its service life due to excessive wear. Therefore, this creation is based on the lack of thrust surfaces of conventional scroll compressors. [New content] This creation is a concave structure of the thrust surface of a compressor, which is mainly used in a scroll compressor. The scroll compressor has an upper scroll and a lower scroll, and the lower scroll is provided in A thrust surface of a support base, and a lower scroll is disposed on the thrust surface of a support base, a crank shaft is pivotally connected in the support base and one end is connected to a rotational power, and a crank is formed at the top end of the crank shaft And, the bottom end surface of the lower full roll is pivotally connected through the crank, so that the lower scroll and the upper scroll form an eccentric relative orbiting movement to form a high-pressure fluid generating device. M270266 One of the objectives of the concave structure of the thrust surface of the compressor is to form a concave surface with a specific plane size and depth in the thrust surface at the top of its support base, and to achieve a better oil film through the configuration of the concave surface. Distribution, which can provide good lubricating effect, to reduce the friction loss of components, and extend its service life. Another purpose of the concave structure of the thrust surface of the compressor created by this invention is to promote the introduction of lubricating oil into the thrust surface through the concave surface of the thrust surface to provide the lubricant required for the oil film establishment. In order to make those skilled in the art understand the purpose, characteristics and effects of this creation, the following specific examples are given in conjunction with the accompanying drawings, which will be described in detail later.

The top of the crank shaft (13a) forms a crank (13b), and the end of the lower scroll (13) is pivotally connected through the crank (13b), so that the lower The scroll (13) and the upper scroll (12) form an eccentric relative orbiting motion, which is used to generate and rotate the M270266 high-pressure working gas. ^ Months> As shown in Figs. 2, 3 and 4, the aforementioned support seat (the top surface of a sentence forms a thrust surface (15), and the thrust surface (15) forms several concave surfaces (i5a) and The oil guide groove (15d), wherein the concave surface (15a) has an appropriate depth and a planar size, and cooperates with the relative movement of the thrust surface (15) and the A thirst roll (13) to form an appropriate configuration for establishing the stop _Oil film ⑽ of the thrust surface (15) and the lower scroll (13); and, the oil guide groove ⑽) has an appropriate depth, and the lubricant is guided into the thrust surface 卩 and the lower scroll (1, 3) Between. Taking Figures 2, 3, and 4 as examples, the thrust surface is formed with several concave surfaces ⑽), and each concave surface ⑽) forms a radial distribution, so that the lower thirst roll (13) is in the operation process. When orbiting relative to the thrust surface (15), observe the path trajectory ㈤ generated by its single position point, and the plane size and / woodiness of each concave surface (15a) are matched with the thrust surface (15) The relative movement speed and direction of the orbit (M) with the lower scroll (13), so that the lubricating oil between the lower scroll (13) and the thrust surface (10) is sufficient to establish an oil film of an appropriate thickness (16 ) To form an appropriate oil film pressure distribution () and promote the oil film (16) to be evenly distributed to disperse the contact stress between the lower scroll (13) and the thrust surface (15) and provide its lubrication.
