Abstract
The utility model discloses a hydraulic cylinder with large swing helical angles, comprising an output shaft, a first helical bar, a second helical bar, a guide sleeve, a balance valve, a sleeve, a first end cover, a second end cover and a cylinder barrel; the outer surfaces of the first and second helical bars are provided with teeth, and the inner surfaces of the guide sleeve, the first end cover and the sleeve are provided with teeth; the output shaft is connected with one end of the first helical bar and is meshed with the first end cover, the other end of the first helical bar is sleeved at the guide sleeve which is connected with the second helical bar, and the sleeve is connected with the other end of the cylinder barrel; and the second end cover is fixed at the inner end surface of the sleeve, directions of the helical angles, being 50 degrees, of the first helical bar and the second helical bar are opposite, and the length of the guide sleeve is one sixth of the sum of the lengths of the first helical bar and the second helical bar. The hydraulic cylinder with the large swing helical angle has the beneficial effects that the abrasion of oblique threads can be reduced by lengthening the guide sleeve, so the service life of the swing cylinder can be prolonged, and the swing angle accuracy, the service life of the oblique teeth and the swing speed can be improved by enlarging the helix angle.
Description
Technical field
The utility model relates to the swing cylinder of Hydraulic Power Transmission System, is specifically related to a kind of large helix angle oscillating motor.
Background technique
Occasions that the large helix angle swing cylinder can need to rotate for all realize rotating, promote, feed, location action, and safe and reliable solution is provided.But the large helix angle swing cylinder that uses at present is at pendulum angle precision, swing speed and very large defective was arranged on working life, and the revolution gap that produces when especially turning round is too high; When swing speed is larger, although buffering is arranged, swing cylinder two ends and helical gear or easily damage, even fracture.
Summary of the invention
For the above-mentioned narrow limitation that existing large helix angle swing cylinder exists, the utility model provides a kind of precision higher more stable large helix angle swing cylinder.
The technological scheme that the utility model adopts for achieving the above object is:
a kind of large helix angle swing cylinder comprises output shaft, the first helix bar, the second helix bar, guide sleeve, equilibrium valve, sleeve, the first end cap, the second end cap and cylinder barrel, described the first helix bar and described the second helix bar outer surface are evenly equipped with tooth, and the internal surface of described guide sleeve and described the first end cap is evenly equipped with tooth, and the internal surface front end of described sleeve is furnished with tooth, described output shaft is connected with an end of described the first helix bar, it is also intermeshing that described the first helix bar passes described the first end cap that is fixed in described cylinder barrel one end, the other end of described the first helix bar is sheathed and be engaged in described guide sleeve, described guide sleeve and described the second helix bar are connected and fixed, described sleeve is placed in described the second helix bar and intermeshing, the other end of described sleeve and described cylinder barrel is connected and fixed, described the second end cap is fixed in the interior edge face of described sleeve, the helix angle opposite direction of described the first helix bar and described the second helix bar and angle are 50 degree, the length of described guide sleeve is the sixth of described the first helix bar and described the second helix bar length summation.
Above-mentioned large helix angle swing cylinder wherein, is provided with sealing between described the first end cap and described cylinder barrel.
Above-mentioned large helix angle swing cylinder wherein, is provided with sealing between described sleeve and described cylinder barrel.
Above-mentioned large helix angle swing cylinder wherein, is provided with sealing between described the second end cap and described sleeve.
Above-mentioned large helix angle swing cylinder, wherein, the material that described guide sleeve uses is copper.
The beneficial effects of the utility model are: (1) increases the length of guide sleeve, the wearing and tearing that produce when reducing inside and outside tiltedly thread engagement, thus improve the swing cylinder life-span; (2) increase lead angle, to reduce angular error, improve the pivot angle precision, change the raising helical teeth life-span thereby slow down angle, and can improve swing speed.
Description of drawings
Fig. 1 is the structural representation of a kind of large helix angle swing cylinder of the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as restriction of the present utility model.
a kind of large helix angle swing cylinder of the utility model, comprise output shaft 1, the first helix bar 2, the second helix bar 5, guide sleeve 4, equilibrium valve 3, sleeve 6, the first end cap 9, the second end cap 7 and cylinder barrel 8 as shown in Figure 1, output shaft 1 is connected with an end of the first helix bar 2, the first helix bar 2 passes the first end cap 9 and intermeshing that is fixed in cylinder barrel 8 one ends, the other end of the first helix bar 2 is sheathed and be engaged in guide sleeve 4, guide sleeve 4 and the second helix bar 5 are connected and fixed, sleeve 6 is placed in the second helix bar 5 and intermeshing, sleeve 6 is connected and fixed with the other end of cylinder barrel 8, the second end cap 7 is fixed in the interior edge face of sleeve 6, the helix angle opposite direction of the first helix bar 2 and the second helix bar 5 and angle are 50 degree, thereby the increase of angle has improved the life-span that the pivot angle precision has improved helical teeth, also can improve swing speed, the length of guide sleeve 4 is the sixth of the first helix bar 2 and the second helix bar 5 length summations, lengthened the length of guide sleeve 4, the wearing and tearing that produced when having reduced inside and outside tiltedly thread engagement, thereby improved the life-span of swing cylinder.
The principle of technique scheme is: hydraulic oil enters cylinder barrel 8 by equilibrium valve 3, the oil circuit that processes along oblique screw thread enters the afterbody of the second helix bar 5, promoting the second helix bar 5 after mineralization pressure travels forward, the second helix bar 5 drives the first helix bar 2 again, also namely drives output shaft 1 and moves clockwise; When the reverse fuel feeding of hydraulic oil, the second 5 of helix bars begin to drive equally the first helix bar 2 to the afterbody motion from front end, and output shaft 1 is moved counterclockwise, so repeatedly work, and make output shaft 1 realize swinging back and forth.
Further, between the first end cap 9 and cylinder barrel 8, between sleeve 6 and cylinder barrel 8, be equipped with sealing between the second end cap 7 and sleeve 6, arranging of sealing guarantees that hydraulic pressure can be closed among cylinder barrel 8 all the time, guaranteed the stable and efficient of swing cylinder work.
Further, the material that guide sleeve 4 adopts is copper, obtains than being easier to, and cost is also lower.
The above is only the utility model preferred embodiment; not thereby limit claim of the present utility model; so the equivalent structure that all utilization the utility model specifications and diagramatic content are made changes, and all is included in protection domain of the present utility model.
