Abstract
The invention relates to a slipper structure of a bidirectional inclined-plate type compressor. The slipper structure comprises a body, wherein a plane central point of the body is provided with a central oil storage pit; the central oil storage pit is taken as one end, a point on a corresponding periphery of the body is taken as the other end, and two ends are provided with at least two symmetrical oil grooves; the circular face of the body is connected by a plurality of different line segments smoothly: the middle part is an upper plane, two sides of the upper plane are connected with a contact friction section through a transition circular arc section, and the contact friction section is connected with one end of a chamfer circular arc section through an oil guiding section; and the other end of the chamfer circular arc section is connected with the plane of the body. The invention has the beneficial effects: the slipper structure is improved, the surface treatment procedures of a slipper ball pit and an inclined plate of the compressor are omitted, and the production cost is reduced; and the friction seizing generated by the slipper, a piston and the inclined plate of the compressor is solved thoroughly.
Description
Technical field
The present invention relates to a kind of automobile air conditioner compressor, relate in particular to the piston shoe structure in this compressor.
Background technique
Fig. 1 is the internal structure schematic representation of two-way tilted-plate compressor in the prior art.As seen from Figure 1: when main shaft 1 rotation, drive swash plate 2 rotations, make front-rear reciprocation movement in the cylinder hole of piston 5 in front-bank rotor housing 3 and rear-bank rotor housing 4, thereby in cylinder body, produce pressurized gas, between the both sides of swash plate 2 and piston 5, two crawler shoes 6 are arranged respectively as the transient motion part between swash plate and the piston.
In such compressor arrangement, when compressor ran up, the arc surface of crawler shoe 6 and piston produced powerful sliding friction, and the plane and the swash plate face of crawler shoe 6 also produce powerful sliding friction simultaneously.
By Fig. 2 A, Fig. 2 B as seen: existing crawler shoe arc surface is half sphere 601, and the plane is a smooth flat 602.Fluid is difficult for entering with piston and swash plate friction the time, kills thereby compressor is produced.
As seen from Figure 1: prior art adopts more to be done one deck and crosses layer probability that the reduction compressor is killed on piston ball pit 7 and swash plate surface 8.But this structure has increased the generation that the cost of compressor also can't be avoided accident simultaneously fully greatly.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of sliding shoe structure of two-way tilted-plate compressor, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: body; Trapped fuel hole, one center is set on the planar central point of described body; Cheating with described center trapped fuel is an end, upward any is at least 2 symmetrical oil grooves of the other end setting with the corresponding periphery of described body; The arc surface of described body is by many different line segment smooth connections: the centre is to go up the plane, connects by the transition circle segmental arc in the both sides on last plane and touches the friction section, and contact friction section is by an end of Oil Guide section connection chamfering arc section; The other end of chamfering arc section connects the plane of body.
Compared with prior art, the invention has the beneficial effects as follows: improved sliding shoe structure, removed the surface treatment procedure of compressor slide shoe ball hole and swash plate, reduced cost of production; And thoroughly solved compressor and killed because of the friction that crawler shoe and piston, swash plate produce.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
By Fig. 3 A, Fig. 3 B as seen: the present invention includes: body 60; Trapped fuel hole, one center 68 is set on the planar central point of described body 60; With described center trapped fuel hole 68 be an end, to go up a bit with described body 60 corresponding peripheries be at least 2 symmetrical oil grooves 67 of the other end setting; The arc surface of described body 60 is by many different line segment smooth connections: the centre is to go up plane 61, connects by transition circle segmental arc 62 in the both sides on last plane 61 and touches friction section 63, and contact friction section 63 is by ends of Oil Guide section 65 connection chamfering arc sections 66; The other end of chamfering arc section 66 connects the plane of body 60.
Described at least 2 symmetrical oil grooves 67 are 4.
The sphere diameter of two sections circular arcs of described transition circle segmental arc 62 and Oil Guide section 65 is identical or different, and the sphere diameter of these two sections circular arcs is than the little 0.001-0.3 of contact friction section 63 sphere diameters.
Described transition circle segmental arc 62 revealed section arc length are between 0.5-4mm.
Described plane 61 diameters of going up are between 1-5mm.
The arc surface that the present invention will have crawler shoe now changes the irregular sphere of being made up of plane on multi-section circular arc and into, guarantees that the refrigeration lubrication oil of compressor inside can enter between crawler shoe and the piston attrition surface, can guarantee the usability of compressor simultaneously again.
With increasing by two symmetrical oil grooves and center trapped fuel hole on the plane of existing crawler shoe, guarantee that the refrigeration lubrication oil of compressor inside can enter between the attrition surface of crawler shoe and swash plate, can guarantee the usability of compressor simultaneously again.
The spherical of crawler shoe of the present invention is by last plane 61, and transition circle segmental arc 62 contacts friction section 63, and Oil Guide section 65 and chamfering arc section 66 are formed.Chamfering arc section 66 contacts smooth, nothing scuffing for guaranteeing crawler shoe with piston ball pit.The sphere diameter of two sections circular arcs of transition circle segmental arc 62 and Oil Guide section 65 is more smaller than contacting friction section 63 sphere diameters.When compressor operation, all the time be in heeling condition the time because of crawler shoe, transition circle segmental arc 62 has a side to be exposed at outside the piston ball pit all the time outward slightly at this moment, the interior refrigeration lubrication oil of compressor this moment then can be in Oil Guide section 65 enters crawler shoe and piston ball pit junction plane, the crawler shoe top is a facet simultaneously, can deposit sub-fraction oil, guarantee that crawler shoe and piston ball pit can sufficient lubrications.
The plane of crawler shoe increases by two symmetrical oil grooves 67 and center trapped fuel hole 68, and when crawler shoe and swash plate friction, the refrigeration lubrication oil in the compressor then can enter junction plane through oil groove, and trapped fuel hole in center has guaranteed that crawler shoe and swash plate can sufficient lubrications.
In the compressor operation process, adopt one aspect of the present invention to have removed the surface treatment procedure of compressor slide shoe ball hole and swash plate, reduced cost of production, thoroughly solved compressor on the other hand and killed because of the friction of crawler shoe and piston, swash plate generation.
