Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Shown in Fig. 3, comprise main shaft 10 and eccentric shaft 20 according to the bent axle 100 of the compressor of the utility model embodiment.
The outer circumferential face of main shaft 10 is provided with oil guide slot 11, and one end of oil guide slot 11 has upper oil hole 12.Eccentric shaft 20 is located at one end of main shaft 10 and is suitable for coordinating with connecting rod.When connecting rod matches with bent axle 100, connecting rod can be set on the outer circumferential face of eccentric shaft 20.Eccentric shaft 20 is provided with oil drainage hole 21, oil drainage hole 21 and oil guide slot 11 conducting.
The outer circumferential face of eccentric shaft 20 is provided with the groove 22 radially caved inward.That is, the outer circumferential face of eccentric shaft 20 is provided with groove 22, and groove 22 is along the caving inward of radial direction of eccentric shaft 20.Thus, when on the outer circumferential face that connecting rod is set in eccentric shaft 20, eccentric shaft 20 can diminish with the area that coordinates between connecting rod, namely the friction area between eccentric shaft 20 and connecting rod reduces, thus the friction between eccentric shaft 20 and connecting rod is reduced, the weight of bent axle 100 can reduce, and improves working life.
According to the bent axle 100 of the compressor of the utility model embodiment, by arranging the groove 22 radially caved inward on the outer circumferential face of eccentric shaft 20, friction area between bent axle 100 and connecting rod is reduced, frictional loss reduces, vibration reduces, and the weight of bent axle 100 reduces simultaneously, and working life extends, the working efficiency of compressor promotes, and reliability improves.
Preferably, groove 22 and oil drainage hole 21 conducting.When compressor start, lubricant oil under the influence of centrifugal force, can enter main shaft 10 along with upper oil hole 12, then reach eccentric shaft 20 by oil guide slot 11.The part arriving the lubricant oil of eccentric shaft 20 can be discharged from oil drainage hole 21, and flow in groove 22.Now, groove 22 can serve as a passage for conducting lubricating oil, lubricant oil can at groove 22 Inner guide, eccentric shaft 20 and connecting rod can be ensured, and sufficient lubricant oil supplies, reach better lubrication effect, fretting wear between further reduction bent axle 100 and connecting rod, reduces vibration, improves working life.
As shown in Figures 2 and 3, can arrange and be connected oilhole 13 between oil guide slot 11 with oil drainage hole 21, the lubricant oil in oil guide slot 11 can flow in eccentric shaft 20 by connecting oilhole 13.Alternatively, oil guide slot 11 can spirality, to improve the lubrication effect to bent axle.
As shown in Figure 1 to Figure 3, in embodiments more of the present utility model, groove 22 is formed as the annular extended along the circumference of eccentric shaft 20.That is, groove 22 be formed as being located at eccentric shaft 20 outer circumferential face on and around the eccentric shaft circular groove of 20 1 weeks.Thus, lubricant oil can at groove 22 internal circulation flow, and make to form the ring shaped oil passage that guides lubricating oil flow between eccentric shaft 20 and connecting rod, the utilization ratio of lubricant oil is higher, and the greasy property between eccentric shaft 20 and connecting rod is better, and frictional loss is less.
Alternatively, at eccentric shaft 20 axially, groove 22 can be located at the middle part of eccentric shaft 20.Thus, lubricant oil preferably between eccentric shaft 20 and connecting rod, can ensure the effectively lubricating between eccentric shaft 20 and connecting rod.
In concrete examples more of the present utility model, groove 22 equals 1/3rd of the axial length L of eccentric shaft 20 at the size d axially of eccentric shaft 20.Thus, namely can ensure can to have between eccentric shaft 20 and connecting rod sufficient lubricant oil, ensure lubrication effect, can also ensure that eccentric shaft 20 relatively large coordinates area with having between connecting rod simultaneously, ensure the reliability and stability of compressor operating.
Be understandable that, when reality manufactures, due to reasons such as errors, groove 22 can be a bit larger tham or be slightly smaller than 1/3rd of the axial length of eccentric shaft 20 at the size d axially of eccentric shaft 20, and this is also by within the protection domain of the application.
Oil drainage hole 21 can be formed as various shape, such as circular port, square opening or irregular shape hole etc.Such as, in an embodiment of the present utility model, oil drainage hole 21 is formed as circular, and groove 22 is more than or equal to the aperture of oil drainage hole 21 at the size d axially of eccentric shaft 20, comparatively large to ensure the size of groove 22, makes lubricant oil can smooth outflow.
As shown in Figure 1 to Figure 3, groove 22 has two sidewalls 222 and a diapire 221, and oil drainage hole 21 can be located on the diapire 221 of groove 22.Thus, the lubricant oil flowed out from oil drainage hole 21 can flow directly in groove 22, and make lubricant oil utilization ratio higher, lubricity is good.Preferably, oil drainage hole 21 can be located at the middle part of diapire 221.Specifically, at eccentric shaft 20 axially, oil drainage hole 21 is positioned at the neutral position of diapire 221.Thus, lubricant oil flow in groove 22 evenly and more smooth and easy, high lubricating effect.
Shown in Fig. 3, two sidewalls 222 of groove 22 are respectively perpendicular to diapire 221, and diapire 221 is formed as the plane paralleled with the axis of eccentric shaft 20.Be understandable that, the structure of groove 22 is not limited in this, and the sidewall 222 of groove 22 can not be vertical with diapire 221, and diapire 221 also can not parallel with the axis of eccentric shaft 20.Such as, at eccentric shaft 20 axially, diapire 221 can be formed as arc, and two sidewalls 222 are formed as arc respectively with the joint of diapire 221.The bent axle 100 of this kind of structure is easier to manufacture and intensity is higher.
According to embodiments more of the present utility model, main shaft 10 and eccentric shaft 20 are integrally formed.That is, bent axle 100 is formed as one part, and the bent axle 100 of this kind of structure is convenient to manufacture, overall construction intensity and stability high, working life is longer.
Comprise connecting rod and the bent axle 100 etc. according to the utility model embodiment according to the compressor of the utility model embodiment, bent axle 100 coordinates with connecting rod and is connected.Owing to having above-mentioned useful technique effect according to the bent axle 100 of the utility model embodiment, therefore can have better lubrication effect according to the compressor of the utility model embodiment, frictional loss is little, reduces vibration, working efficiency and performance boost.
Can be reciprocating type refrigeration compressor according to the compressor of the utility model embodiment.According to the compressor of the utility model embodiment other form and operation be known for the person of ordinary skill of the art, be not described in detail at this.
