Next, explain the operation and the effect of the compressor of putting down in writing by the present invention.
When power connection when the compressor, drive motor 20 is driven thus and produces rotating force.The rotating force of drive motor 20 is passed to internal gear 50 by running shaft 80, so that internal gear 50 rotations.Thus, rotating force is passed to the external gear 40 that contacts at multiple spot with internal gear 50, so that external gear 40 rotates together.
Because the number of teeth of internal gear 50 is different with the number of teeth of external gear 40, a plurality of point of contact of formation and a plurality of compression volume between the tooth of the tooth of internal gear 50 and external gear 40.When internal gear 50 rotations, external gear 40 rotates together, and the contacting points position between internal gear 50 and the external gear 40 changes.Simultaneously, the volume of compression volume also correspondingly changes.When the Volume Changes of compression volume, the gas that enters in the seal container 10 by suction pipe 11 is inhaled into compression volume, is compressed and by discharge pipe 12 dischargings.
When the number of the tooth 41 of external gear 40 is 7, the number of the tooth 51 of internal gear 50 is 6 o'clock, forms 6 compression volumes between the tooth 51 of the tooth 41 of external gear 40 and internal gear 50, as shown in Figure 6.If internal gear 50 is that the basis is rotated counterclockwise with the line X1 among Fig. 6, three compression volume P1, P2 and P3 are in suction condition, and its volume increases gradually, other three compression volume P4, P5 and P6 are in compressive state, and its volume reduces gradually.Because the number of the tooth 51 of internal gear 50 is 6, as long as internal gear 50 rotates 60 °, the compression volume that is formed by internal gear 50 and external gear 40 repeats to form with same shape.Thus, the gas a compression volume compression discharges by tapping equipment.Therefore, as long as internal gear 50 rotations once, pressurized air is by tapping equipment discharging six times.
In said process, when running shaft 80 rotations, oil gun 110 rotations that are connected in running shaft 80 are with fuel feeding.Oil by oil gun 110 supplies is mobile along the first oil circuit F of running shaft 80, is directed to the second oil circuit F2 of upper bearing (metal) 60 thus.Then, the oil that guides to the second oil circuit F2 of upper bearing (metal) 60 is directed between external gear 40 and the cylinder 30 by the second oil circuit F2.Guide to oil between external gear 40 and the cylinder 30 and be provided between the circumferential surface of gear patchhole 32 of the outer circumferential surface of external gear 40 and cylinder 30, therefore when external gear 40 and cylinder 30 carry out relative movement mutually, be used as lubricant oil.
More particularly, the oil that guides to the second oil circuit F2 of upper bearing (metal) 60 is directed to the oil groove 33 of cylinder 30 by the first oily port 34 of cylinder 30.Thus, oil is conducted between the circumferential surface of gear patchhole 32 of the outer circumferential surface of external gear 40 and cylinder 30.When external gear 40 and cylinder 30 carried out relative movement mutually, oil was as the lubricant oil between the circumferential surface of the gear patchhole 32 of the outer circumferential surface of external gear 40 and cylinder 30.Then, by the second oily port 35 of cylinder 30, oil is directed to the 3rd oil circuit F3 of lower bearing 70, returns the bottom surface of seal container 10 then.
If being formed on the 3rd oil circuit F3 of lower bearing 70 is made up of first oilhole 74 and second oilhole 75, in the operating process, the oil of carrying out lubricated operation between external gear 40 and cylinder 30 is by first oilhole 74, second oilhole 75 and suction port 73 flow to the bottom surface of seal container 10, and the oil that is positioned at suction port 73 is partly guided to compression volume together with the air that sucks suction port 73.The oil that guides to compression volume is conducted at internal gear 50, external gear 40, and two elements that carry out relative movement in upper bearing (metal) 60 and the lower bearing 70 are mutually carried out greasing thus, reduce the friction between the element thus.
Industrial applicibility
As mentioned above, in the compressor by the present invention record, the rotation that is meshing with each other of external gear 40 and internal gear 50, as long as drive motor 20 rotates once, air for continuous is discharged repeatedly.Therefore, because the rotatable member that rotates with the rotor of drive motor is such as running shaft, internal gear etc. are rotation evenly mutually, and gas is stabilized compression, and compression efficiency improves, and obtains stability.
In addition, because oil is supplied between external gear 40 and the cylinder 30 reposefully, the there is mainly acting on frictional force, and the friction between external gear 40 and the cylinder 30 reduces thus, and the reliability that improves external gear 40 and cylinder 30 also reduces because the noise that friction causes.
And, when the oil that is kept at seal container 10 bottom surfaces is provided between external gear 40 and the cylinder 30 and supply oil when turning back to the bottom surface repeatedly, be not only the frictional heat that is created between external gear 40 and the cylinder 30, also have the heat that produces at other elements all to be cooled.Therefore, prevented the overheated of element.
Owing to specialize the present invention with several forms that do not break away from spirit or major character, be appreciated that the above embodiments are not limited by the details of foregoing description, unless stated otherwise, but can in the spirit and scope that its appended claims limited, extensively amplify, therefore all changes and distortion all fall into the boundary and the scope of claim, or in the equivalency and scope that comprise by appended claims.
