Abstract
A driving device for an air compressor includes a base, a motor, a main gear, a subordinate gear, a shaft, a weight, and a driving arm combined with an air cylinder and a cylindrical member. When the motor is electrified, the main and the subordinate gear are rotated, with the subordinate gear rotating the shaft, which then rotates the weight. The weight then rotates centrifugally to let a first end of the driving arm rotate and then the piston formed the second end of the driving arm is moved to reciprocate back and forth in the cylindrical member to produce compressed air to flow out for use.
Description
- 1. Field of the Invention
- This invention relates to a driving device for an air compressor, particularly to one having a base, a main gear fixed on the base and engaging with a subordinate gear, a weight fixed on the shaft of the subordinate gear, and a driving arm connected with eccentrically with the weight. When a motor is powered, the main gear and the subordinated gear are orderly rotated to let the weight rotate so that the driving arm may eccentrically be moved so that a piston formed at one end of the driving arm and contained in an cylinder member to reciprocate for pushing out a large amount of compressed air.
- 2. Description of the Prior Art
- A conventional air compressor shown in
FIGS. 1 and 2 , includes amotor 90, afixing base 91 located in front of themotor 90, a main gear 9 fixed on the spindle of themotor 90, asubordinate gear 93 fixed on thefixing base 91 and engaging with themain gear 92. Further, aneccentric shaft 94 is connected with thesubordinate gear 93, and apiston rod 95 is connected with theeccentric shaft 94. Then thepiston rod 95 has its end fixed with apiston 96 movably fitted in anair cylinder 97, which has aninlet valve 98 and anoutlet valve 99. - When the
motor 90 is powered, themain gear 92 is rotated and then thesubordinate gear 93 is then rotated accordingly, moving thepiston rod 95 with thepiston 96 up and down. Then thepiston 96 sucks in air during down movement in theair cylinder 97 and then into theair cylinder 97 through theinlet valve 98, and compresses out air in theair cylinder 97 through theoutlet valve 99 during up movement therein. - However, in the conventional air compressor the
piston 96 generates sucking force during down movement, sucking outer air into theair cylinder 97 in a limited amount, and then presses out air in theair cylinder 97 through theoutlet valve 99, but the driving distance and force of thepiston rod 95 is comparatively small, and accordingly the air amount compressed out is also comparatively small, not ideal in the inlet and outlet amount of air. - This invention has been devised to offer a driving device for an air compressor, which is possible to produce a large amount of air pressure to obtain preferable intake and outgo of air pressure.
- The feature of the invention is a motor, a main gear, a subordinate gear, a weight fixed on a shaft, and a driving arm having a piston at an end, and a air cylinder and a cylindrical member combined together. The motor is combined with a rear side of a base, having a spindle, and the main gear is fixed on the spindle and engaging with the subordinate gear fixed on the shaft, which the driving arm has its one end combined with. So when the motor is powered, the main and the subordinate gear are rotated together, and then the shaft rotates with the subordinate gear, also rotating the weight and a first end of the driving arm connected eccentrically with the weight so that the piston formed at a second end of the driving arm may be moved to reciprocate back and forth in the cylindrical member to suck in air and compress out air out of the air cylinder to obtain a large amount of compressed air.
- This invention will be better understood by referring to the accompanying drawings, wherein:
-
FIG. 1 is a simple view of a conventional air compressor with air sucking condition; -
FIG. 2 is a simple cross-sectional view of the conventional air compressor; -
FIG. 3 is an exploded perspective view of a driving device for an air compressor in the present invention; -
FIG. 4 is a perspective view of the driving device for an air compressor in the present invention; -
FIG. 5 is a cross-sectional view of the driving device for an air compressor in the present invention, showing air compressed out; -
FIG. 6 is a cross-sectional view of the driving device for the air compressor in the present invention, showing air sucked in; and,FIG. 7 is a cross-sectional view of the driving device for the air compressor in the present invention, showing the piston moved to the outermost point. - A preferred embodiment of a driving device for an air compressor in the present invention, as shown in
FIGS. 3, 4 and 5, includes abase 1, amotor 10, amain gear 11, asubordinate gear 2, ashaft 14, aweight 3, adriving arm 4, anair cylinder 5, and acylindrical member 54 as main components. - The
motor 10 is fixed with a rear side of thebase 1, and thebase 1 has ahole 12 for twobearings 13 to fit therein, and ashaft 14 fitted though the twobearings 13. - The
main gear 11 is fixed on the spindle of themotor 10, and located in parallel beside thehole 12 of thebase 1. - The
subordinate gear 2 is fixed on a rear end of theshaft 14 with ascrew 20, engaging with themain gear 11 to rotate together. - The
weight 3 is preferably fan-shaped, fixed eccentrically on a front end of theshaft 14 at its small end, having ashaft hole 30 and a threadedhole 31 in the small end. - The
driving arm 4 has its first end eccentrically connected with theweight 3, having the first end formed with ahole 40, with abearing 41 fitted in thehole 40 and ascrew 42 passing through thebearing 41 and screwing with theweight 3. Thedriving arm 4 has its second end formed with apiston 43. - The
air cylinder 5 is combined laterally with the front end of thebase 1 by means ofplural bolts 6, provided with arecess 40 in a front portion, anair outlet 51 formed in therecess 40, adisc 52 with athrough hole 520 and twogaskets 53 sandwiching thedisc 52 fitted in therecess 50. Further, acylindrical member 54 is provided, having one end fitted stably in therecess 50 and the other end connected with thebase 1. Thepiston 43 of thedriving arm 4 is movably contained in thecylindrical member 54. - In using, referring to
FIGS. 4, 5 , 6 and 7, themotor 10 is first powered, and themain gear 11 is rotated by themotor 10, with thesubordinate gear 2 also rotated by themain gear 11. Then theshaft 14 is rotated together with thesubordinate gear 2, driving theweight 3, which rotates one end of thedriving arm 4, which then moves in a line to let thepiston 43 to reciprocate back and forth in thecylindrical member 54. Then theweight 3 is rotated to swing around centrifugally, with the first end of the drivingarm 4 rotating. When the larger portion of theweight 3 moved to the outer side, thepiston 43 is pushed to move further into the interior of thecylindrical member 54, as shown inFIG. 5 , with air squeezed through thethrough hole 520 of thedisc 52 to flow out of theoutlet 51. As theweight 3 is rotating to have its larger portion coming to the upper side, the first end of thedriving arm 4 is rotating downward, making thepiston 43 inclined as shown inFIG. 6 , with a gap formed between the lower side of thepiston 43 and the inner wall of hecylindrical member 54, so that outer air flows into thecylindrical member 54, as thepiston 43 moving outward may cause sucking force. - When the larger portion of the
weight 3 rotates to move to the inner side, thepiston 43 moves to the outermost point in thecylindrical member 54, as shown inFIG. 7 , with thepiston 43 becoming located in parallel to thecylindrical member 54 in a sealed condition. In this way, theweight 3 is further rotated by thesubordinate gear 2 to move thepiston 43 reciprocate forcefully in thecylindrical member 54, compressing out the air in thecylindrical member 54. - As can be seen from the aforesaid description, the engagement and rotation of the
main gear 11 and the subordinate 2 gear can force theweight 3 rotate stably and accurately so that theweight 3 can move the first end of thedriving arm 4 to let thepiston 43 reciprocate in thecylindrical member 54 and compressing a large amount of air for producing the most preferable intake and outgo of compressed air. - While the preferred embodiment of the invention has been described above, it will be recognize and understood that various modifications may be made therein and appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
