Description
Technical field
The present invention relates to a kind of differential straight reciprocating motion, belong to field of mechanical technique.
Background technique
Existing linear shuttle mechanism, main have reciprocal screw mandrel, traverse guide pulley, reciprocal structural types such as groove drum (being mainly used in textile yarn reels) and reciprocal cam, and the structure of can saying so is different, and using scope is extensive.Take a broad view of this class linear shuttle mechanism of prior art, its structure is relatively complicated, straight reciprocating motion speed is slower, especially its reciprocating conversion time is longer, that is to say in its to-and-fro motion conversion place, 1 relatively slowly process of motion is arranged, the requirement of this balanced to-and-fro motion condition of just can not satisfying the demand, for example textile yarn is reeled, because the to-and-fro motion transfer speed at fro guiding-yarn member two ends is slower, so that cause the yarn diameter two ends that bobbin reels big and middle little, this be after textile technology can not be allowed to.And this class linear shuttle mechanism of prior art, when back and forth changing, it has instantaneous impact force, and this easy motion to its mechanism is disadvantageous, has restricted the raising of its to-and-fro motion speed.
Summary of the invention
It is very fast that the present invention aims to provide a kind of to-and-fro motion speed, and motion is steady, and back and forth the fast differential straight reciprocating motion of transfer speed to overcome the deficiency of prior art, satisfies the reciprocating demand of fast uniform.
The present invention realizes that the technical though of its purpose is, employing is equal to the ring-type double strand chain of pitch, and wherein row's chain is driven along a direction revolution by hinge wheel, and wherein another arranges chain, drive with power and export the differential minor sprocket that reciprocal slide block slides and is equipped with, reciprocating along 2 chutes of sliding bed.Because the pitch diameter of the pitch ratio hinge wheel of differential minor sprocket is little, move to the two ends of sliding bed when differential minor sprocket, and when the set chute of the sliding bed of disengaging was controlled, differential minor sprocket promptly raised speed and moves or the title differential motion, and the conversion of very fast realization moving direction; And because the motion of double strand chain is a constant motion, and not only motion is steady, and does not have impact force when moving direction is changed, and can effectively improve balanced reciprocating speed, thereby realize purpose of the present invention.
Based on above-mentioned technical though, the present invention realizes that the technological scheme of its purpose is:
A kind of differential straight reciprocating motion, its innovative point is:
A, comprise having and be equal to being parallel to each other of width along the sliding bed of first chute laterally arranged apart and second chute, the powerdriven drive sprocket of acceptance that is dynamically connected with sliding bed one end, the driven sprocket that equates with the drive sprocket number of teeth that is dynamically connected with the sliding bed the other end, the double annular link chain that is equal to pitch, end face have vertically upward, and there are laterally the differential sprocket wheel of feather key and laterally reciprocal slide block down in the feather key bottom surface; Following row's annular link chain of described double annular link chain is meshed equipped with drive sprocket and driven sprocket; The following feather key of differential sprocket wheel slides equipped with first chute and second chute of sliding bed; The row's of going up annular link chain of double annular link chain is meshed with differential sprocket wheel; The vertical chute in bottom surface of vertically going up the laterally reciprocal slide block of feather key and power output of differential sprocket wheel slides equipped; Laterally back and forth the secondary slip of slide block and cross slide way is equipped with and can be along transverse reciprocating motion;
The two ends of the isolating bar between first chute and second chute of b, described sliding bed have the following feather key of being convenient to differential sprocket wheel to import the chamfering or the round end of first chute and second chute respectively; Described chamfering or blunt end respectively and the distance between drive sprocket and the driven sprocket center, all less than the Pitch radius of differential sprocket wheel;
The number of teeth of c, described drive sprocket, greater than the number of teeth of differential sprocket wheel, and both numbers of teeth poor 〉=1;
Distance between first chute of d, described sliding bed and the center line of second chute equals pitch diameter poor of drive sprocket and differential sprocket wheel.
Can understand by above given technological scheme, differential sprocket wheel of the present invention is under the interference of laterally reciprocal slide block, its straight reciprocating motion is the constant speedpump motion, and be on duty movable sprocket under last row's annular link chain drives, arrive sliding bed one end along first runner movement, and when breaking away from the control of first chute, because the pitch diameter of differential gear is little to be that the number of teeth is few, and under original annular link chain drives, differential acceleration revolution, but, can only very fast translation carry out the transition in second chute, and along second runner movement because differential gear is subjected to laterally the back and forth interference of slide block.When differential gear under last row's annular link chain drives, move to the other end of sliding bed, then equally very fast translation carries out the transition in first chute, so goes round and begins again, and realizes to-and-fro motion.Because the distance between described first chute and the second chute center line, the pitch diameter that is drive sprocket and differential sprocket wheel is poor, and two chamfers or the round end of the isolating bar between described 2 chutes, all and the distance between drive sprocket and the driven sprocket center, all less than the Pitch radius of differential sprocket wheel, therefore, differential sprocket wheel is meshed with last row's annular link chain all the time.Thereby realized purpose of the present invention.
Here should be noted that the number of teeth that strengthens drive sprocket and differential sprocket wheel is poor, can obtain faster back and forth transfer speed.
The present invention advocates that also the number of teeth of described differential sprocket wheel is 〉=10 even number.This is in order to make the isolating bar between sliding bed institute first chute that is located at and second chute, the enough rational width of maintenance.
The present invention also advocates the equipped cross slide way pair of described and reciprocal slide block slip, is 2 fixing guide rods of two ends arranged apart, and described 2 guide rods are equipped along the through hole slip of lateral arrangement with laterally reciprocal slide block respectively; Or be located at the laterally back and forth fixing guide plate in slide block top and two ends, and described guide plate with laterally back and forth slide block be horizontal keyway secondary slide equipped; Or be located at horizontal back and forth slide block vertically before and after 2 fixing guide rails of two ends of both sides, and described 2 guide rails with laterally back and forth slide block be horizontal keyway secondary slide equipped.Here given is 3 kinds with the horizontal reciprocal slide block structural type of equipped cross slide way pair of sliding, but be not limited to this.In fact, as long as can make reciprocal slide block transverse movement, and the structure that can not rotate all can adopt.The cross slide way pair of wherein said 2 guide bars goes for the textile yarn winding device.
Characteristics such as after technique scheme was implemented, what the present invention had was simple in structure, and volume is little, and motion is steady, and to-and-fro motion speed is fast, and reciprocal transfer speed is fast are conspicuous.
