Abstract
The invention discloses an overall oscillating type traverse mechanism with a Fourier curve non-circular gear for a reeling machine. Power is input by a driven chain wheel arranged at one end outside a box on a spindle; a worm and a driving bevel gear wheel are sequentially arranged on the spindle at the end inside the box; a second shaft, a first shaft and a crank shaft are sequentially arranged in the box; a worm gear is fixed on the second shaft; a driven bevel gear wheel and a driving first-order Fourier curve non-circular gear are fixed on the first shaft; a driven second-order Fourier curve non-circular gear is fixed on the craft shaft; and one ends of two rocker arms are arranged on the crank shaft respectively, and the other ends of the two rocker arms are movably sleeved on the first shaft. According to the traverse mechanism, a transverse rod has a longer time close to a uniform velocity during a reciprocating motion process; the starting and ending positions of the transverse rod are enabled to change periodically during a stroke; the defect that two sides are high after silk threads are winded to a spinning utensil because the velocity of left and right extreme positions is low due to the stroke is overcome; and the sealing effect is good because all components of the mechanism are contained in one box.
Description
Technical field
The present invention relates to a kind of reeling machine traverse mechanism, be specifically related to a kind of integrated oscillating type Fourier's pitch curve non-circular gear reeling machine traverse mechanism.
Background technology
The effect of traverse mechanism is to make the strand that is wound on little form netted silk sheet, it affect a sheet be shaped with quality, the rereeling of dry mass move back the difficulty or ease of separating and coiling loading amount how much etc.At present; Traverse mechanism on the reeling machine of selling on the market at home, its stroke motion are mainly realized through three kinds of mechanisms, cylindrical cam mechanism; The type mechanism can realize the at the uniform velocity reciprocating motion of cross winding bar through changing the cylindrical cam profile, but when switching-over, can produce very big impact; The cyclic train of constant traverse and the combined mechanism of crank block, the type mechanism kinematic is more steady, but the characteristics of motion can not meet the demands, and recessed in the middle of the silk sheet of formation, both sides are protruding, are unfavorable for the be shaped increase of increase degree of stable and silk sheet thickness of a sheet; The combined mechanism design of cyclic train and the crank block of change journey helps increasing the overlapping cycle, improves the surperficial flatness of silk sheet, but under constant condition of cycle, when traverse reduced, winding angle also reduced.It moves apart from motion is main and realizes through two kinds of mechanisms, and cylindrical cam mechanism and plate cam mechanism are less because of moving apart from the traverse of motion; Frequency is lower; These two kinds of mechanisms both can satisfy the characteristics of motion, did not produce impact again, but all there are the problem of processing difficulties in cylindrical cam and plate cam slideway.
Summary of the invention
In order to overcome the problem that exists in the background technology, the object of the present invention is to provide a kind of integrated oscillating type Fourier's pitch curve non-circular gear reeling machine traverse mechanism.
In order to achieve the above object, the technical scheme of the present invention's employing is:
Power is positioned at the driven sprocket input on the outer end of casing by being installed in main shaft, and main shaft is equipped with worm screw and active bevel gear successively on the end in casing; Both sides are equipped with second, first and crank axle from bottom to up successively in the casing, and worm and wheel is meshed, and worm gear is fixed on second; Initiatively bevel gear is meshed with driven bevel gear; Driven bevel gear all is fixed on first with active single order Fourier pitch curve non-circular gear; Initiatively single order Fourier pitch curve non-circular gear is meshed with driven second order Fourier pitch curve non-circular gear; Driven second order Fourier pitch curve non-circular gear is fixed on the crank axle, and on the end difference mounting crank axle of two rocking arms, the other end difference kink of two rocking arms is on first; One end of two cranks is separately fixed on the two ends that extend to the outer crank axle of casing, and an end of two connecting rods is hinged with the other end of crank separately respectively, and the other end of two connecting rods is hinged with cross winding bar separately respectively; The conjugate cam of being made up of main cam and auxiliary cam is fixed on second; Conjugate cam, fork-shaped fork and two rollers that are fixed on the fork-shaped fork are formed conjugate cam mechanism; The fork-shaped fork is the conjugate cam mechanism driven member; One end of fork-shaped fork through two rollers respectively with conjugate cam in main cam, auxiliary cam contact, the other end of fork-shaped fork is connected with rocking arm mutually; Casing all has chute at place, the overhanging two ends of crank axle, during work crank axle along with rocking arm around swinging in first chute on casing.
When described rocking arm was in vertical position, the plane that cross winding bar and driven second order Fourier pitch curve non-circular gear axle center are formed was a horizontal plane.
The beneficial effect that the present invention has is:
1) the present invention adopts the combination of integrated oscillating type Fourier pitch curve non-circular gear and slider-crank mechanism to realize the stroke motion of traverse mechanism; When driven second order Fourier pitch curve non-circular gear rotates a week; Its rotating speed speed changes four times; Just with slide block reciprocating motion one-period slow fast change four times corresponding, thereby make in the cross winding bar reciprocating motion process longer constant speed is around arranged; And the traditional implementation method of stroke motion is a pair of eccentric gear and a pair of gear ratio is the roller gear of 1:2, EB type traverse mechanism for example, and the present invention is simple in structure by contrast.
2) the present invention adopts conjugate cam to drive rocking arm generation reciprocally swinging and realizes moving apart from motion of traverse mechanism; Make all the time position of cross winding bar in stroke motion produce periodic the variation, produce silk thread around arriving the higher shortcoming of little back the right and left thereby overcome because of stroke motion left and right sides two limit positions speed is little; And move apart from the traditional implementation method of motion is to realize through gear, edge cam and the return spring of few tooth difference, EB type traverse mechanism for example, and the present invention is simple in structure, easy to process by contrast, and does not have the relaxing of spring problem.
3) each member of the present invention is included in the same casing, good sealing effect, and also casing is fixed in the course of work, has only correlated parts such as the rocking arm swing of box house, and dynamics is good; And HR2 type and EB type is the whole box body swing.
