Abstract
The utility model discloses a scroll compressor, relating to the technical field of fluid machinery. The scroll compressor comprises a moving scroll plate, a bearing gasket and a bearing block, wherein the bearing gasket is installed between the moving scroll plate and the bearing block; the bearing gasket is at least provided with a solid lubricating film on the surface jointed with the moving scroll plate; the solid lubricating film is a polytetrafluoroethylene film; and a copper plated layer is arranged between the bearing gasket and the solid lubricating film. Compared with the prior art, the scroll compressor has the beneficial effects that the process of spraying a self-lubricating material onto the surface of the bearing gasket after plating copper on the surface is adopted, so that the solid lubricating film is formed on the surface of the bearing gasket; and the solid lubricating film can improve the self-lubricating capacity between friction mating plates, thus effectively solving the problem that dry friction is generated between the lower end face of the moving scroll plate and the upper end face of the bearing gasket after the scroll compressor works for a period, which causes increase of the frictional resistance of the two friction mating plates and reduction of the efficiency of the scroll compressor.
Description
Technical field
The utility model relates to the fluid machinery technical field, and especially a kind of bearing gasket is installed in the scroll compressor between orbiter and the bearing support.
Background technique
Scroll compressor is to rotate to realize suction, compression and discharge to compressed media by dynamic and static scroll is intermeshing.Bearing gasket is installed between bearing support and the orbiter, and when scroll compressor was worked, the drive shaft orbiter was around the fixed scroll high speed rotating, between this moment orbiter and the bearing gasket also with the circular movement that carries out of the mode of sliding friction.In the prior art, this bearing gasket is to be formed by machining by common steel disc, and any processing is not carried out on its surface, coats very thin one deck lubricating grease on the bearing gasket surface during installation, and orbiter is made through heat treatment process by steel again.During scroll compressor work, the lower end surface of orbiter is in bearing gasket upper-end surface high-speed slide, after work a period of time, the lubricating grease that is coated in the bearing gasket surface slowly can approach exhaustion after orbiter and bearing gasket high-speed friction, after this sliding friction between bearing gasket and the orbiter just becomes the dry friction between the steel, and this dry friction meeting causes the surface friction drag between the mating plate to increase.
The model utility content
The purpose of this utility model provides a kind of scroll compressor, and it can solve, and surface friction drag increases the problem that causes the scroll compressor decrease in efficiency between scroll compressor orbiter and the bearing gasket.
In order to address the above problem, the technical solution adopted in the utility model is: this scroll compressor comprises orbiter, bearing gasket, bearing support; Described bearing gasket is installed between described orbiter and the described bearing support, and described bearing gasket is provided with one deck solid lubricant film on the surface that it engages with orbiter at least.
In the above-mentioned scroll compressor technological scheme, can also be more specifically: one deck solid lubricant film on described bearing gasket surface be teflon.
Further, be provided with copper layer between described bearing gasket and the described solid lubricant film.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, owing to will spray again the treatment process of self lubricating material after the bearing gasket appearance employing copper facing, so that the bearing gasket surface forms one deck solid lubricant film, this layer solid lubricant film can make the selflubricating ability between the friction pair part strengthen, efficiently solve after scroll compressor work a period of time and form dry friction between the orbiter lower end surface and bearing gasket upper-end surface, cause that two friction pair part surface friction drag increase, the problem of scroll compressor Efficiency Decreasing.
2, the wear extent of orbiter lower end surface reduces, and orbiter improves working life greatly.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Kind scroll compressor as shown in Figure 1 comprises orbiter 1, bearing gasket 2, bearing support 3; Bearing gasket 2 is installed between orbiter 1 and the bearing support 3, and the bearing gasket 2 in the present embodiment is provided with one deck solid lubricant film on the surface that it engages with orbiter 1, and solid lubricant film is preferably poly tetrafluoroethylene 4; Be provided with copper layer between bearing gasket 2 and the poly tetrafluoroethylene 4.
During work, the lower end surface of orbiter 1 is high speed rotating on the upper-end surface of bearing gasket 2, and bearing gasket 2 surface is owing to there being copper layer 5 reinforcing body lubricating films 4, so that it is strengthened with the selflubricating ability between the orbiter 1, surface friction drag reduces, the efficient raising.
