Detailed description of the invention
In the following description, with reference to each embodiment, present invention is described.But, person of skill in the art will appreciate that and can implement each embodiment when neither one or multiple specific detail or together with other replacement and/or addition method, material or assembly.In other situation, not shown or known structure, material or operation are not described in detail in order to avoid making the aspects of various embodiments of the present invention obscure.Similarly, for the purpose explained, elaborate specific quantity, material and configuration, in order to provide the comprehensive understanding to embodiments of the invention.But, the present invention can implement when not having specific detail.Further, it should be understood that each embodiment shown in accompanying drawing is illustrative expression and is not drawn necessarily to scale.
Below in conjunction with specific embodiments and the drawings, the invention will be further described; elaborate more details in the following description so that fully understanding the present invention; but the present invention obviously can implement with the multiple alternate manner being different from this description; those skilled in the art can do similar popularization, deduction according to practical situations when without prejudice to intension of the present invention, therefore should with content constraints protection scope of the present invention of this specific embodiment.
As shown in Figure 1, in the cylinder body 1 of oscillating compressor, main shaft 3 and swash plate 5 are around axial-rotation, the end face of swash plate 5 promotes planetary plate 7 to do axial oscillating motion, multiple pistons 10 hinged with planetary plate 7 respectively are reciprocating in respective cylinder-bore 11, it is achieved the compression to cylinder-bore inner refrigerant gas.
As shown in Figure 1 and Figure 2 the A-A sectional view of Fig. 1 (Fig. 2 be), the rotation-preventing mechanism of planetary plate 7 includes bulb guide finger 17, and this bulb guide finger 17 includes bulb 17a and pin handle 17b.Offering gathering sill 12 at body inside wall of cylinder tool, planetary plate 7 has axial boss 13, axial boss 13 is provided with the pin-and-hole 14 radially extended.The pin handle 17b of this bulb guide finger 17 is inserted in pin-and-hole 14.The bulb 17a of this bulb guide finger 17 is placed in gathering sill 12, and the sphere of bulb 17a slides in gathering sill 12 and swings.Being provided with crawler shoe 15 between bulb 17a and gathering sill 12, crawler shoe 15 can slide axially in gathering sill 12, hinged between bulb 17a and crawler shoe 15.
Owing to the bulb 17a of bulb guide finger 17 is limited in gathering sill 12, it is impossible to rotate around compressor axis, and circumferentially displaced between bulb guide finger 17 and planetary plate 7 is limited, and makes planetary plate 7 to spin.But owing to bulb guide finger 17 can slide axially in gathering sill 12 with crawler shoe 15, and can and crawler shoe 15 between relatively rotate, therefore the axial oscillating motion of planetary plate is not limited.
As it is shown on figure 3, press-fit a sliding bearing 16 in pin-and-hole 14 with interference, the inner peripheral surface of sliding bearing 16 is coated with Teflon (PTFE), MoS2Or WS2Inner peripheral surface sliding contact Deng friction coat 16a, pin handle 17b Yu sliding bearing 16.Sliding bearing 16 is bearing steel or Cu alloy material.The gross thickness of the coating 16a of sliding bearing 16 is about 1mm, and only existing planetary plate pin-and-hole 14 slightly being done expansion can realize, the problem solving planetary plate abrasion.
In the aforementioned embodiment, gathering sill 12 can be configured as on guide pad as shown in Figure 4.
Although the present invention is with preferred embodiment openly as above, but it is not for limiting the present invention, and any those skilled in the art without departing from the spirit and scope of the present invention, can make possible variation and amendment.Therefore, every content without departing from technical solution of the present invention, according to any amendment, equivalent variations and modification that above example is made by the technical spirit of the present invention, each fall within the protection domain that the claims in the present invention define.
