Specific embodiment
To describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As depicted in figs. 1 and 2, main body 1 is included according to the cylinder 100 of the present invention, described main body 1 has access road 11; Bindiny mechanism 2, described main body 1 at least part of in described bindiny mechanism 2, described bindiny mechanism 2 has for will be described The connectivity slot 23 that access road 11 connects with pumping trachea 41.
As shown in Figure 3 and Figure 4, main body 1 is in substantially circular.It is formed with main body 1 and connect with the pumping trachea 41 of housing 4 Access road 11, exit passageway and for installing the vane slot 16 of slide plate.Main body 1 extends along its axial A, and vertically A has relative first end 13 and the second end 14.Main body 1 also have along its axially through chamber 17.
As shown in Figure 5 and Figure 6, the section of the axial A perpendicular to described main body 1 for the described bindiny mechanism 2 is substantially ringwise.Even Connection mechanism 2 includes along the wall 21 of the axial A extension perpendicular to described main body 1 and prolongs from described wall 21 along the axial A of described main body 1 The ring surface 22 stretched, described ring surface 22 is located at the outside of the outer peripheral face 12 of described main body 1.Described connectivity slot 23 is formed at described On ring surface 22.Do not have partly being welded and fixed with the housing 4 of compressor of connectivity slot 23 in ring surface 22.Described connection Mechanism 2 also have along described main body 1 axially through inner chamber 23, described inner chamber 23 connected with the chamber 17 of described main body 1, with Make to be located at the space connection of described cylinder 100 both sides in housing 4.
Preferably, bindiny mechanism 2 can be made up of low-carbon steel material.Compared in prior art by casting pig or powder The cylinder 100 that metallurgical part is made and housing 4 weld, and bindiny mechanism 2 can be greatly reduced with the weld interval of compressor housing 4 And welding stress is little, firm welding is good.
In conjunction with shown in Fig. 1 and Fig. 2, in the present embodiment, described wall 21 towards described second end 14 side wall with described Main body 1 is connected towards the side wall 15 of described first end 13 by spot welding.In conjunction with shown in Fig. 5, Fig. 6 and Fig. 7, for the ease of adding Work, before spot welding, the wall 21 of described bindiny mechanism 2 has and dashes forward towards described second end 14 towards the side wall at described second end 14 The multiple juts 24 for side wall 15 spot welding towards described first end 13 with described main body 1 going out.This kind of welding manner The active force of described main body 1 mainly extended along the axial A of described main body 1, thus reduces described main body 1 radially as far as possible Deformation, the risk of excessive situation in the revolution electric current such that it is able to reduce compressor.
In the present embodiment, described jut 24 is nine, and nine described juts 24 are circumferentially arranged.Certain, In other optional embodiments, the quantity of described jut 24 can also for four, five or other.
In order to not increase cost and preferably be welded and fixed with bindiny mechanism 2, described main body 1 can be made up of casting pig.
Shown in reference Fig. 2, in one preferred embodiment, the medial wall of described ring surface 22 and described main body 1 Periphery 12 face has gap 3.Described bindiny mechanism 2, as intermediate member, is welded with described housing 4 by its outer edge surface, in weldering In termination process, because described ring surface 22 has certain gap 3 with described main body 1, this gap 3 can reduce from described annular Face 22 is to the heat transfer of described main body 1 and active force, thus reduces the deformation radially of described main body 1 as far as possible.
As shown in figure 8, housing 4 and cylinder described above 100 can be included according to the compressor of the present invention.Set on housing 4 It is equipped with pumping trachea 41 and exhaustor.Cylinder 100 described bindiny mechanism 2 welding excessively is arranged in described housing 4.On cylinder 100 Offer access road 11 and exit passageway.
More specifically, compressor can also include clutch shaft bearing 5, second bearing 6, bent axle 7, motor 8, slide plate, roller etc.. Clutch shaft bearing 5, second bearing 6 are respectively disposed on the two ends of cylinder 100.Roller is contained on bent axle 7, and during work, roller is along cylinder 100 inwalls roll, and slide plate is installed in the vane slot 16 open up on cylinder 100.When roller rolls in the intracavity that works, slide plate exists In the presence of spring, its front end keeps and the cylindrical close contact of roller, thus the point of contact of slide plate and roller and cylinder 100 inwall will Cylinder 100 inner chamber is divided into suction muffler and compression chamber two parts, and the volume size of suction muffler and compression chamber is with roller rotation Change, the pressure of compression intracavity gas then reduces with compression chamber and increases, thus completing the work process of compressor.
In one preferred embodiment, described housing 4 and described bindiny mechanism 2 pass through at least three circumferentially arranging Individual solder joint is welded and fixed, to ensure described housing 4 and described bindiny mechanism 2 stable connection it is also possible to avoid due to housing 4 temperature Too high lead to problem on deformation.
In one preferred embodiment, the external diameter of described bindiny mechanism 2 is adapted with described housing 4.Keeping institute In the case of stating the size constancy of main body 1, according to the size of inner shell, the size of bindiny mechanism 2 can be chosen, so that institute State bindiny mechanism 2 and adapt to described housing 4.This way it is secured that being applied to various differences in the case of not changing main body 1 The housing 4 of size, thereby increases the versatility of described main body 1, reduces manufacturing cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair Change, equivalent, improvement etc., should be included within the scope of the present invention.
