Technical field
The utility model relates to a kind of crawler shoe of swash-plate-type compressor, relates in particular to a kind of crawler shoe that is used for the swash-plate-type compressor of Vehicular air-conditioning apparatus.
Background technique
As shown in Figure 1, oblique tray type compressor has swash plate 2, piston 4 and a pair of crawler shoe 5 between piston 4 and swash plate 2 that is connected with drive main spindle 1.When drive main spindle 1 rotation, swash plate 2 is with its rotation, and 5 motions drive piston 4 to-and-fro motion thereby the rotation of swash plate 2 drives crawler shoe.Each crawler shoe 5 plays the effect of a slider, and generally it simultaneously is a hemisphere face, and another side is plane (can be with reference to figure 2, Fig. 2 is the sectional view of existing crawler shoe), and its hemisphere face contacts slip with the ball hole of piston 4, and the plane contact of its plane and swash plate 2 is slided.Crawler shoe of the prior art generally adopts the steel ball cutting and grinding to become or forms with the aluminum alloy blank forging.The crawler shoe of making thus all has shortcoming: too heavy by the crawler shoe that steel ball is made; And adopt aluminum alloy forged process loaded down with trivial details, the cost height.
The model utility content
The utility model is when guaranteeing to have the function of sliding on swash plate and piston, a kind of in light weight, simple and high crawler shoe of lubricity of processing is provided, it simultaneously is a hemisphere face, another side is the plane, described crawler shoe inside is formed with cavity, and have a through hole and external communications at least, the diameter of described through hole is less than the diameter of described cavity biggest place.
In above-mentioned crawler shoe, described crawler shoe inner hollow, described through hole is positioned on the hemisphere face of described crawler shoe.
In above-mentioned crawler shoe, described through hole is positioned at the hemispherical center of described crawler shoe.
In above-mentioned crawler shoe, there is hole on described crawler shoe plane.
In above-mentioned crawler shoe, described crawler shoe inner hollow, described through hole is positioned at the plane of described crawler shoe.
In above-mentioned crawler shoe, described through hole is positioned at the center on described crawler shoe plane.
In above-mentioned crawler shoe, the horizontal edge of described crawler shoe has chamfering or circular arc.
The utility model has not only reduced the weight of itself but also make its processing simple when guaranteeing to have the function of sliding on swash plate and piston.Simultaneously,, make the lubricity of the utility model and swash plate and piston space be significantly improved, satisfy the feasible lubrication property of compressor of the present utility model that adopts and also be improved because of storing lubricant oil in cavity and the through hole.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the compressor sectional drawing;
Fig. 2 is the sectional view of existing crawler shoe;
Fig. 3 A is an embodiment's of crawler shoe a sectional view;
Fig. 3 B is another embodiment's of crawler shoe a sectional view;
Fig. 3 C is another embodiment's of crawler shoe a sectional view.
Embodiment
Please earlier referring to Fig. 3 A, Fig. 3 A is an embodiment's of crawler shoe a sectional view.As shown in the figure, the utility model has the two sides, and it simultaneously is a hemisphere face 31, and this face 31 contacts with the ball hole of piston, and another side is plane 32, the plane contact of this plane 32 and swash plate.Be formed with the cavity 33 of certain wall thickness in crawler shoe inside, this cavity 33 is by being arranged on the through hole 34 and the external communications of hemisphere face 31 central authorities, and the diameter of through hole 34 is less than the diameter of cavity 33 biggest places.Usually, the slide member of compressor inner structure lubricated usually with being contained in that lubricant oil in the compressor forms mist of oil with circuit refrigerant gas in the running compressor and taking the lubricant oil of mist of oil form to each sliding parts and carry out, mist of oil enters cavity 33 by through hole 34, thereby make to be full of lubricant oil in through hole 34 and the cavity 33, improved the lubricity of crawler shoe and piston space thus.Have in one in plane 32 central authorities and to cheat 35, in this effect in hole 35 similar with the effect of above-mentioned through hole 34 and cavity 33, it guides mist of oil to enter between crawler shoe and swash plate, improves the lubricity between crawler shoe and swash plate thus.In addition, in order further to improve lubricity of the present utility model, 32 edges can form chamfering or circular arc on the plane.
Should be understood that through hole 34 is not limited to be in the central authorities of hemisphere face 31; Simultaneously, interior hole 35 also be not limited to be positioned at plane 32 central authorities and hole 35 dispensable.In addition, the chamfering at 32 edges, plane or circular arc neither be essential.
Please again referring to Fig. 3 B, Fig. 3 B is another embodiment's of crawler shoe a sectional view.In the present embodiment, it also has the two sides, and one side is a hemisphere face 41, and this face 41 contacts with the ball hole of piston, and another side is plane 42, the plane contact of this plane 42 and swash plate.Portion also forms cavity 43 within it, and cavity 43 is by through hole 44 and external communications.Different with the foregoing description is, through hole 43 is arranged on plane 42 central authorities, and its diameter makes lubricant oil be full of through hole 44 and cavity 43 less than the diameter of cavity 43 biggest places, has improved the lubricity between crawler shoe and swash plate thus.In addition, in order further to improve lubricity of the present utility model, 42 edges can form chamfering or circular arc on the plane.
Should be understood that through hole is not limited to be in hemispherical central authorities.In addition, the chamfering or the circular arc at 42 edges, plane are optional.
See also Fig. 3 C at last, Fig. 3 C is another embodiment's of crawler shoe a sectional view.The profile of present embodiment is a hemisphere face in original one side, and another side is to have done some variations on the basis on plane.The profile of present embodiment by one a little the characters in a fancy style of modification " 2 " rotation constitute.The hemisphere face 51 of above-mentioned formation contacts with the ball of piston hole, the plane 52 of formation and the plane contact of swash plate.Present embodiment is identical with last embodiment's essence, the inner cavity 53 that forms, through hole 54 and the external communications of this cavity 53 by being arranged on plane 52, the diameter of the biggest place of through hole 54 should be less than the diameter of cavity 53 biggest places, oil easy to lubricate is full of through hole 54 and cavity 53, has improved the lubricity between crawler shoe and swash plate thus.In addition, in order further to improve lubricity of the present utility model, 52 edges can form chamfering or circular arc on the plane.
The shape that should be understood that the foregoing description cavity can change as required.In addition, the chamfering or the circular arc at 52 edges, plane are optional.
What deserves to be mentioned is that the utility model can be by machine shapings such as punching press or extruding, preparation process is simple.
Should be understood that the utility model is not limited in a through hole, its can be provided with two, three so that more multi-through hole make the inner cavity that forms of crawler shoe, improve the lubricity between crawler shoe and piston, swash plate thus.In addition, the foregoing description is only given an example for convenience of description, is not the restriction to scope of the present utility model.For the general personnel in present technique field, can under the situation that does not break away from spirit of the present utility model, make many variations.Therefore, the scope advocated of the utility model should be as the criterion so that the claim in claims is described.
