Description
Technical field:
The utility model relates to a kind of transmission device, specifically is a kind of transmission device that rotatablely moves that straight line motion is converted to.
Background technique:
Through spur rack and gear meshing transmission is a kind of comparatively common transmission device that rotatablely moves that straight line motion is converted to, and this transmission device is made the straight-tooth strip with push rod usually, makes gear shape to rotor.Through the engagement of rack and pinion, make the straight line motion of push rod convert rotatablely moving of rotor into, but the sense of rotation of rotor is to change along with the reciprocal of push rod, can not form rotation in the same way.
Connecting rod can convert straight reciprocating motion into orientation and rotatablely moves in addition, and like internal combustion engine, the thermal power transfer that produces during with fuel combustion is the mechanical energy of reciprocating motion of the pistons, converts the crankshaft rotating motion again into and external outputting power.But piston makes a round trip, and bent axle (crank) has rotated a week, can not realize deciding the rotation of angle.Therefore, connecting rod is difficult for accurately realizing complicated motion, and secondly connecting rod designs more complicated, and the wearing and tearing between kinematic pair are bigger.
The model utility content:
The utility model technical issues that need to address are: provide a kind of and can convert linear reciprocating motion to directed rotatablely move, whenever toward complex line once, the straight line motion that rotates to an angle converts the transmission device that rotatablely moves to simultaneously.
For solving the problems of the technologies described above; The utility model adopts a kind of like this straight line motion to convert the transmission device that rotatablely moves to, comprises the pushing cover that does reciprocating linear motion, converts linear reciprocating motion to rotating shaft that the commentaries on classics core that rotatablely moves and continuous pivoted housing, output rotatablely move; Pushing cover has first extrusion block that two or more than two end that circumferentially is uniformly distributed with at it has first compressive plane, and pushing cover also has the spring that return is used; Continuous pivoted housing is enclosed within to be changeed on the core, and this continuous pivoted housing has in its quantity that circumferentially is uniformly distributed with and equates with first extrusion block and the end has second extrusion block of second compressive plane; Change core and have respectively the inclination compressive plane that second compressive plane extruding with first compressive plane of first extrusion block and second extrusion block matches, change the axial Returnning spring that core also has the usefulness that axially resets; The end axis of rotating shaft rotates in being movably arranged on the circumferential spacing hole that changes the core output terminal and with the commentaries on classics core synchronously.
This transmission device also has matrix; The circumferential stop collar of pushing cover is located on the matrix, and pushing cover also is provided with and prevents that pushing cover from axially shifting out the limit baffle ring of matrix; Continuous pivoted housing is packed on the matrix; Spring housing is located on the continuous pivoted housing and two ends offset with matrix and pushing cover respectively; Axial Returnning spring is set in the rotating shaft and two ends offset with matrix and commentaries on classics core respectively.
Described circumferential spacing hole is a long strip through hole, is plugged in the end of the rotating shaft in the long strip through hole and size, the shape of long strip through hole and matches.
The utility model compared with prior art has the following advantages: the straight line motion of the utility model convert to pushing cover through doing reciprocating linear motion of the transmission device that rotatablely moves, with linear reciprocating motion convert to rotating shaft that the commentaries on classics core that rotatablely moves and continuous pivoted housing and output rotatablely move the most at last the straight line motion of pushing cover converted rotatablely moving of rotating shaft to.That is to say that pushing cover advances, spring is extruded, and the inclination compressive plane of core is changeed in first extrusion block extruding of pushing cover; Change core and be pushed and advance and forms rotations, axially Returnning spring is extruded, and the while rotating shaft is rotated with the commentaries on classics core synchronously; After spring is extruded to the limit; Pushing cover halts, and changes core and stops operating, and rotating shaft also stops operating synchronously; Pushing cover is retreated; Spring promotes pushing cover and retreats returning position; Axially Returnning spring extruding commentaries on classics core is retreated; The inclination compressive plane extruding of changeing core continues second extrusion block of pivoted housing and makes the commentaries on classics core still do the rotation of above-mentioned direction, and the rotation of above-mentioned direction is done in rotating shaft simultaneously synchronously, stops operating until axial Returnning spring returning position.In the utility model; The every to-and-fro motion of pushing cover once, the angle that rotating shaft is rotated in the same direction is: changeing the angle between the two inclination compressive planes on the core, is n if change the tilt quantity of compressive plane of core; Then during the every to-and-fro motion of pushing cover one time, the corner of rotating shaft is 360 °/n.The transmission device of the utility model converts the linear reciprocating motion of pushing cover the angle stepping of rotating shaft to, can satisfy from linear reciprocating motion to the conversion requirement that rotatablely moves, and can carry out accurate control in the same way again.In addition the utility model simple in structure, transmission efficiency is high, and wearing and tearing, power consumption are few.
As improvement, this transmission device also has matrix; The circumferential stop collar of pushing cover is located on the matrix, and pushing cover also is provided with and prevents that pushing cover from axially shifting out the limit baffle ring of matrix; Continuous pivoted housing is packed on the matrix; Spring housing is located on the continuous pivoted housing and two ends offset with matrix and pushing cover respectively; Axial Returnning spring is set in the rotating shaft and two ends offset with matrix and commentaries on classics core respectively.Pushing cover, continuous pivoted housing, spring and axial Returnning spring can be arranged according to concrete environment, promptly as long as satisfy the cooperation assembled relation, can be installed in respectively on the diverse location of matrix.
As further improvement, described circumferential spacing hole is a long strip through hole, is plugged in the end of the rotating shaft in the long strip through hole and size, the shape of long strip through hole and matches; The long strip through hole is as circumferential spacing hole, and is spacing reliable, and processing is simple, convenient; Prevented the rotation of rotating shaft in circumferential spacing hole; Adopt the project organization of through hole simultaneously, prevented to change the straight line motion of core and the straight line motion that drives rotating shaft, that is to say; Rotating shaft only with change that core rotates synchronously and not with change the motion of core synchronous linear, the output movement of rotating shaft just is converted rotatablely moving like this.
