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 of fixedlying 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 the plane, 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.The slide member of compressor inner structure lubricated is contained in normally that lubricant oil in the compressor forms mist of oil with circuit refrigerant gas in the running compressor and takes the lubricant oil of mist of oil form to each sliding parts and carry out, therefore, in order to make the lubricant oil of mist of oil shape enter between crawler shoe and swash plate or the piston, prior art (as shown in Figure 2, Fig. 2 is the sectional view of existing crawler shoe) form chamfering or circular arc A at the edge on crawler shoe plane, the lubricant oil of guiding mist of oil shape enters between crawler shoe and swash plate or the piston.But the effect of this kind method is unsatisfactory, the lubricant oil of mist of oil shape can not enter between crawler shoe and swash plate or the piston fully, thereby cause the lubricant oil deficiency to cause the inordinate wear of swash plate and piston inordinate wear, particularly swash plate, the working life of finally reducing compressor.
The model utility content
The purpose of this utility model is to provide the crawler shoe of the good swash-plate-type compressor that is used for Vehicular air-conditioning apparatus of a kind of lubrication property, it is between piston and swash plate, it comprises spherical part and terrace part, described spherical part simultaneously is a hemisphere face, another side is the plane, described plane is connected with terrace part, form one, described spherical part contacts with the ball hole of piston, the plane contact of described terrace part and swash plate, the maximum diameter of described spherical part is greater than the maximum diameter of described terrace part, and the height of described terrace part is less than 1/2 of described crawler shoe whole height.
In above-mentioned crawler shoe, described terrace part is a cylinder.
In above-mentioned crawler shoe, described terrace part is a round platform, and the less plane of described round platform radius is connected with the plane of described spherical part.
In above-mentioned crawler shoe, in the joint of described spherical part and described terrace part one circular groove is arranged, the diameter of described circular groove is less than the maximum diameter of described terrace part.
In above-mentioned crawler shoe, when scribbling coating on described swash plate, the height of described terrace part is greater than the thickness of described coating.
In above-mentioned crawler shoe, the edge of described terrace part has chamfering or circular arc.
The utility model has improved the lubrication property between crawler shoe and swash plate or the piston, thereby has prolonged the working life of compressor guaranteeing its function of sliding on swash plate and piston when.
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 is an embodiment's of crawler shoe a sectional view;
Fig. 4 is another embodiment's of crawler shoe a sectional view;
Fig. 5 a is another embodiment's of crawler shoe a sectional view;
Fig. 5 b is the partial schematic diagram of Fig. 5 a;
Fig. 6 is the schematic representation that the crawler shoe terrace part contacts with swash plate.
Embodiment
Please earlier referring to Fig. 3, Fig. 3 is an embodiment's of crawler shoe a sectional view.As shown in the figure, the utility model comprises two-part between piston and swash plate: spherical part 31 and terrace part 32, wherein spherical part 31 contacts the plane contact of terrace part 32 and swash plate with the ball hole of piston.Spherical part 31 one sides are hemisphere face 311, and another side is plane 312, and terrace part 32 is a cylinder, and plane 312 is connected with cylinder 32, forms one.Wherein, the maximum diameter of spherical part 31 like this, when crawler shoe contacts with swash plate, just can form a circular groove betwixt and store and collect lubricant oil greater than the maximum diameter φ 2 of terrace part 32; Simultaneously, the height H 1 of terrace part 32 should so just can guarantee the reliability when crawler shoe uses less than 1/2 of crawler shoe whole height H2.Now see also Fig. 6, Fig. 6 is the schematic representation that the crawler shoe terrace part contacts with swash plate.When having oil film to exist on the swash plate 64, the height H 1 of the terrace part of crawler shoe 61 should be greater than the height of oil film, and circular groove just can not override by oil film like this.When scribbling coating 63 on the swash plate 64, the height H 1 of terrace part should be greater than the height H 4 of coating 63, and this is for after preventing coating 63 parts wearing and tearing, and the interlock that meets accident of this sliding shoe structure and coating 63 produces inefficacy.In order further to improve lubricity of the present utility model, the edge of terrace part 32 has chamfering or circular arc 33.
Certainly, the terrace part 32 in the foregoing description also can be a round platform 42 (can be referring to Fig. 4, Fig. 4 is another embodiment's of crawler shoe a sectional view), and the less plane of round platform 42 radiuses is connected with the plane of spherical part 41.
Now see also Fig. 5, Fig. 5 is another embodiment's of crawler shoe a sectional view.Present embodiment also comprises two-part: spherical part 51 and terrace part 52, wherein spherical part 51 contacts the plane contact of terrace part 52 and swash plate with the ball hole of piston.Spherical part 51 one sides are hemisphere face, and another side is the plane, and terrace part 52 is a cylinder or round platform, and the plane of spherical part 51 is connected with cylinder 32, forms one.Wherein, the maximum diameter φ 1 of spherical part 51 is greater than the maximum diameter φ 2 of terrace part 52, also designed circular groove 53 (visible Fig. 5 b in the joint of spherical part 51 and terrace part 52, it is the partial schematic diagram of Fig. 5 a), the diameter phi 3 of circular groove 53 is less than the maximum diameter φ 2 of terrace part 52, be not easy out after can making the lubricant oil of mist of oil shape enter circular groove 53 like this, guaranteeing has sufficient lubricant oil between crawler shoe and swash plate.In order further to improve lubricity of the present utility model, the edge of terrace part 52 has chamfering or circular arc 54.Certainly, identical with above-mentioned two embodiments, when having oil film to exist on the swash plate, the height H 1 of the terrace part of crawler shoe should be greater than the height of oil film; When scribbling coating on the swash plate, the height H 1 of terrace part should be greater than the height H 4 of coating 63.In addition, the reliability when guaranteeing that crawler shoe uses, the height H 1 of terrace part 52 should be less than 1/2 of crawler shoe whole height H2.
Should be understood that terrace part is not limited to cylinder or round platform, and the chamfering at the edge of terrace part or circular arc are not essential.In addition, neither be essential among last embodiment at the circular groove 53 of the joint of spherical part 51 and terrace part 52 design, those of ordinary skills can change as required.
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.
