Abstract
The utility model relates to a core driving device for a seat angle regulator. The utility model is mainly characterized in that a large toothed plate is fixed in a protective jacket, and a small toothed plate which can be rotated in the protective jacket is provided. A double eccentric wheel is arranged in the center hole of a duplicate gear, a rotary shaft with a boss is arranged on the shaft center hole of the double eccentric wheel, the boss of the rotary shaft is arranged in the boss slot of the shaft center hole of the eccentric wheel, and a spring which causes the eccentric distance of the double eccentric wheel to be increased when stretching is arranged in the double eccentric wheel. The large and the small circles of ladder outer teeth of the duplicate gear can be engaged with the inner teeth of the large and the small toothed plates respectively. When the rotary shaft is rotated, the rotary shaft can toggle the eccentric wheel to rotate together, and therefore, the planetary gear transmission is formed to drive the duplicate gear and the small toothed plate. The angle of the utility model can be in stepless regulation, and the utility model has stable transmission, high intensity, strong versability, moderate driving ratio, fast regulating speed, small seat back tip clearance and good operation stability. The utility model is the seat angle regulator with small gap, small torsion and high carrying capacity.
Description
Technical field
The utility model relates to a kind of chair angle adjusting device of planetary gear transmission.
Background technology
Chinese patent ZL94213191.6 has announced a kind of seat angle adjustment, though but this adjuster has angle step-less adjustment, intensity height, highly versatile and non-maintaining advantage, but because structural limitation, when existing in the angular adjustment that realizes backrest, deficiency such as governing speed is slow, gap, backrest top is bigger.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art and provides a kind of governing speed fast, the little seat angle adjustment core transmission device in gap, backrest top.
The utility model is one 2 differential teeth planetary gear drives, and technical scheme is formed by big tooth plate, little tooth plate, duplicate gear, eccentric wheel, spring, steel ball, turning cylinder and with the sheath that these parts are linked together.Be fixed with big tooth plate in the sheath, and the little tooth plate that can rotate in sheath is housed; In the duplicate gear centre bore double eccentric wheel is arranged, the turning cylinder with a boss is arranged in the axle center hole of double eccentric wheel, the boss of turning cylinder places the boss groove in hole, eccentric wheel axle center; Double eccentric wheel is equipped with the spring that when upholding its eccentric throw is increased; The large and small two circle ladder external tooths of duplicate gear can be meshed with the internal tooth of large and small tooth plate respectively, can stir eccentric wheel when turning cylinder rotates and rotate together, thereby drive duplicate gear, the transmission of little tooth plate formation planetary gear.
Described big tooth plate, duplicate gear, turning cylinder, steel ball, little tooth plate, eccentric wheel, spring are fixedly connected through sheath.
Circle matched in said little tooth plate cylindrical was got out of a predicament or an embarrassing situation by steel ball and sheath.
The endoporus sliding fit of described turning cylinder and eccentric wheel, large and small tooth plate.
Boss groove in the hole, described eccentric wheel axle center matches with the boss of turning cylinder, and turning cylinder rotates by boss and promotes the eccentric wheel rotation.
The utility model is owing to adopted the double eccentric wheel structure, make eccentric eccentric throw to float, like this, when recliner is not worked, spring in the eccentric wheel is upheld eccentric throw to be increased, duplicate gear is adjacent to the elimination backlash with big tooth plate, little tooth plate, forms reliable self-locking, makes that gap, backrest top is very little.When recliner work turning cylinder rotated, the spring compression eccentric throw in the eccentric wheel reduced, and duplicate gear produces backlash with big tooth plate, little tooth plate, thereby made the turning cylinder rotation easily, reduced to regulate moment.
Compared with prior art, but the utility model angle step-less adjustment not only, stable drive, the intensity height, highly versatile, and gearratio is moderate, and governing speed is fast, and gap, backrest top is little, and the operation ride comfort is good.It is the chair angle adjusting device of a kind of little gap, little moment of torsion, high bearing capacity, after linking with any type of chair back installing plate and seat support installing plate, the angular adjustment that can be used for automotive seat or other Chair back can satisfy the strict demand of medium-to-high grade car to seat angle adjustor.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the left view of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Among Fig. 1, Fig. 2, form 2 differential teeth planetary gear drive chair angle governor motions by sheath 1, big tooth plate 2, duplex gear 3, turning cylinder 4, steel ball 5, little tooth plate 6, eccentric wheel 7, spring 8.Big tooth plate 2 is fixed in the sheath 1, links by chair back gusset piece and chair basin.Little tooth plate 6 has 25 teeth, and circle matched in platelet plate 6 cylindricals were got out of a predicament or an embarrassing situation by steel ball 5 and sheath 1, and little tooth plate 6 is free to rotate in sheath 1.Interior two eccentric wheels of eccentric wheel fit together mutually and are assemblied in duplicate gear 3 centre bores.The turning cylinder 4 of band boss is arranged in the axle center hole of eccentric wheel 7, and the boss of turning cylinder 4 places the boss groove of eccentric wheel 7 axle center holes, and the boss groove in eccentric wheel 7 axle center holes matches with the boss of turning cylinder 4, and turning cylinder 4 rotates by boss and promotes eccentric wheel 7 rotations.Adorn a spring 8 in the middle of the double eccentric wheel 7, the part of spring 8 is loaded in the eccentric wheel, and another part is loaded in another eccentric wheel, and two eccentric wheels interlock, and spring 8 is clipped in the middle.The eccentric throw of eccentric wheel 7 changes with the compression and the extension of spring 8, regulates the backlash of duplicate gear and big tooth plate, little tooth plate, to reduce rocking of the chair back.Duplicate gear 3 has two circle ladder external tooths, one circle is the great circle external tooth, another circle is the ringlet external tooth, the ringlet external tooth of duplicate gear 3 is meshed with the internal tooth of little tooth plate 6, the great circle external tooth is meshed with the internal tooth of big tooth plate 2, the endoporus sliding fit of turning cylinder 4 and eccentric wheel, large and small tooth plate, handwheel drives this mechanism and does planetary motion by turning cylinder being applied moment of torsion, realizes the step-less adjustment of backrest angle.
