Abstract

The utility model relates to a scroll which comprises a movable scroll and a stationary scroll, wherein the movable scroll and the stationary scroll respectively consist of a scroll body and a corresponding bottom plate; one of the movable scroll and the stationary scroll is made of metal materials, and the other scroll is made of thermoset materials. The two scrolls can reach the optimum matching in mutual matching operation by utilizing the thermoset characteristic of the materials, so that the scroll realizes sealing, decreases the manufacturing precision and the requirement of form and position tolerance, and further decreases the manufacturing cost; meanwhile, the noise and vibration are reduced, the scroll is wear resistant, and the service life is prolonged.

Description

Scroll

Technical field

The utility model relates to the scroll of scroll compressor, particularly a kind of scroll of scroll compressor of low-cost and high-performance.

Background technique

In scroll compressor, two traditional dynamic and static scroll are all made by metal, and as shown in Figure 1, moving scroll, fixed scroll two metal dish are cooperatively interacting, very easily producing when turning round bigger noise and vibration, each other very easily wearing and tearing; Also have moving scroll, fixed scroll in the running, the contact force of the side of its spiral type line only depends on the circumferential centrifugal force of moving scroll, and its contact force is very little; More because the side of moving scroll, fixed scroll two spiral type drums is line contacts, referring to A point among Fig. 1, therefore be difficult to reach the purpose of sealing, very easily leak, so for the precision of spiral type line, wall thickness, highly, the requirement of top and bottom planeness, vortex ring wall and bottom surface perpendicularity is high especially, its precision has decisive influence to the performance of scroll compressor.Therefore people are always constantly managing raising and are guaranteeing its precision, but the raising of precision relates to the performance and the manufacture cost of working machine tool again; But scroll the time is heated and the distortion that caused by external force can make too high precision lose meaning again in work; Therefore conventional best form and position tolerance value is in 8---15 micrometer ranges (" positive displacement compressor handbook Yu Yongzhang chief editor, Beijing Machinery Industry publishing house publishes in October, 2000), so high precision is all very high for the requirement of working machine tool, cutter and frock clamping, have only the special device of import just can reach its required precision, so the manufacture difficulty of scroll compressor is big, processing cost is high, poor performance, be difficult to general promotion and application.

Summary of the invention

The purpose of this utility model provides a kind of scroll and manufacture method thereof, by changing the scroll material, makes two scroll when cooperating running, utilizes material behavior, and two scroll realize sealing by not contacting or the contact of line contact becoming face; In addition, also reduce running noise and vibration, more wear-resisting, the longer service life of scroll, and reduced requirement to scroll precision and form and position tolerance, and then reduced manufacture cost.

The technical solution of the utility model is: a kind of scroll comprises moving scroll, the fixed scroll be made up of spiral type disk body and respective base; Any one scroll in moving scroll, the fixed scroll is made with metallic material, and another scroll is made with having heat cured material, utilizes properties of materials to make two scroll realize best fit when working in coordination running, reaches optimal seal.

A described scroll spiral type disk body also is provided with skeleton.

Described skeleton is porose thin plate: porose thin plate is made with metal or plastics.

Described skeleton and base plate are structure as a whole.

The material of described one of them scroll is to choose from the thermosetting property plastics.

The manufacture method of scroll of the present utility model may further comprise the steps:

Make the spiral type disk body with thin plate;

Be fixed on the metal base plate;

Bottom land injection moulding or coating or cast or mold pressing thermoset plastic material between the outer surface of spiral type disk body and spiral type disk body and sheet metal form scroll.

The beneficial effects of the utility model

A scroll in moving scroll of the present utility model, the fixed scroll is made with metal, another scroll is made with having heat cured material, two scroll are when cooperating running, the heat that utilizes two scroll to be produced in the running solidifies thermosets, make its cooperation reach best, thereby make the contact of two scroll by original not contacting or the contact of line contact becoming face, reach sealing purpose, lower form and position tolerance all can reach its technical requirements as about 100 microns.Because two scroll are made by metal and two kinds of materials of plastics, when cooperating running, reduced noise and vibration, more wear-resisting, longer service life, reduced requirement simultaneously, and then reduced manufacture cost precision and form and position tolerance.

Embodiment

As Fig. 2, scroll of the present utility model shown in Figure 3, comprise moving scroll (1), fixed scroll (2); Wherein, moving scroll (1) is made up of spiral type disk body (4) and base plate (5), and fixed scroll (2) is made up of spiral type disk body (6) and base plate (7); Moving scroll (1) is made with metallic material, and fixed scroll (2) is made with having heat cured material.

As Fig. 4, shown in Figure 5, described fixed scroll (2) spiral type disk body (6) also is provided with skeleton (8), a plurality of holes (9) are arranged on the skeleton (8), apply the thermosetting material bed of material with a base plate (7) bottom land (11) that has the outer surface of hole (10) skeleton (8) on the base plate (7) that skeleton (8) is connected and be connected with skeleton (8).

As shown in Figure 6, moving scroll of the present utility model (1) and fixed scroll (2) cooperate running, because the heat that two scroll are produced when cooperating running solidifies thermosetting plastics, making two dish contacts side surfaces face B is face contacts, realize sealing, reduced requirement, and then reduced manufacture cost scroll precision and form and position tolerance.

As shown in Figure 7, moving scroll of the present utility model (1), fixed scroll (2) cooperate when turning round, because external force and action of high temperature solidify thermosetting plastics after extruding, the distortion, see C among the figure, D place.

In sum, a scroll in moving scroll of the present utility model, the fixed scroll is made with metal, another scroll is made with having heat cured plastic materials, two scroll are when cooperating running, the heat that utilizes a scroll wherein to be produced in the running makes the characteristic of its curing, make the contact of two scroll become the face contact, thereby reach sealing purpose; In addition,, when cooperating running, reduced noise and vibration, more wear-resisting, longer service life, reduced requirement simultaneously, and then reduced manufacture cost precision and form and position tolerance because two scroll are made by one soft one hard two kinds of materials.
