Summary of the invention

To make up drawbacks described above, the present invention discloses a kind of use " chain bar " new technology, rotary motion, torque is converted to directly Line movement pushes or pulls on power, or vice versa, it will move along a straight line, push or pull on the basic mechanical dress that power is converted into rotary motion, torque function It sets, device abbreviation: " chain bar machine ", specifically:

First technical solution of the invention specifically describes are as follows: a kind of chain bar owner will be by: casing one, chain with the channel Y Wheel, sprocket shaft, roller tooth chain, each two pieces of guide pad and each composition of left-handed worm gear, dextrorotation worm gear, worm shaft, latch fitting；Snail Bar axis is made of coaxial four sections (or three sections), is left-hand worm section, right-hand worm section and two (or one) input sections；Left-handed snail Wheel, dextrorotation worm gear modulus, the number of teeth are identical, oppositely oriented, left-hand worm section, right-hand worm section modulus and screw pitch phase on worm shaft Together, oppositely oriented.

The chain linkage is made are as follows: two sprocket shafts are parallel, are cased with left-handed worm gear and dextrorotation worm gear, Ji Geyi to key connection respectively Part sprocket wheel, is freely rotatably mounted in casing, inside and outside when the center of two sprocket shafts is away from two roller tooth chain mistake sections is equal to The convex tooth of chain can phase buckle one by one distance, worm shaft and sprocket shaft be vertically mounted in casing, left-hand worm section and right Rotation worm screw section is accurately engaged with left-handed worm gear and dextrorotation worm gear respectively, and two (or one) of worm shaft hold input section to stretch out outside casing, Using two input ports in the Y type channel of casing as starting point, two roller tooth chains are pressed clockwise and counterclockwise respectively, around corresponding to The sprocket wheel of side, during two roller tooth chain mistake sections are by Y type channel and sprocket wheel circular arc, the inside and outside chain of two roller tooth chain mistake sections The convex tooth of plate can phase buckle one by one, be combined into chain bar, after then passing through a pair of of guide pad in the machine of being symmetrically mounted on, latch fitting will Chain club head connects " lock " and gets up, and the input terminal of two roller tooth chains can unlimited continued access.

Due on worm shaft left-hand worm section and right-hand worm section respectively on two sprocket shafts left-handed worm gear and dextrorotation Worm gear engagement, so, when the input section of rotary worm axis, driving left-handed worm gear to rotate with dextrorotation worm gear is: revolving speed is identical, turns To on the contrary, same, also revolving speed is identical for two coaxial sprocket wheels, it is reversely rotated to turn to, and therefore, two roller tooth chains are in two chain wheel belt It is " advance " at the same speed or synchronized " retrogressing " under dynamic.

Therefore, the working principle of chain bar machine is: when the direction advance by two roller tooth chains " merging ", and rotating input section When, for two roller tooth chains during passing through Y type channel and sprocket wheel circular arc, the convex tooth of the inside and outside carrier bar of mistake section is mutually embedded in phase Button, mutually embedding interlocking gets up to form chain bar one by one, and after passing through guide pad, the head of chain bar is lived by latch fitting " lock ", because of two roller tooth chains The all wrong section of the every section of the intermediate inside and outside convex tooth of carrier bar is mutually embedding one by one, and mutually withstands one by one, and therefore, the chain bar of composition is cannot to be bent, In rigid state；Simultaneously output chain bar tail portion clamped by two pieces of guide pads, a pair of of guide pad both as export chain bar guiding, The issuable moment of flexure of chain bar is undertaken again, so, by the input section of rotation chain rod machine, the rigid of straight line " stretching " movement can be exported Property chain bar, is changed into linear motion by rotary motion to realize, or be changed into thrust function by torque.

Conversely, when two roller tooth chains are retreated to the direction of " separated ", and when the input section of rotary worm, make rigid chain bar It " is retracted " by straight line, during passing through two sprocket wheel circular arcs and the type channel Y, the inside and outside chain of two roller tooth chains of sub-assembly chain bar The convex tooth of plate will thread off in de-embedding one by one, by " segmentation " at two flexible roller tooth chains, so, by rotating input section, output The straight line " retracting " of rigid chain bar moves, it is thereby achieved that being changed into linear motion by rotary motion, or is changed into drawing by torque The function of power.

According to above-mentioned, chain bar machine is using worm and gear as input form, so, which also has worm and gear Deceleration and reverse self-locking performance, therefore, which is known as: worm and gear chain bar machine is the torque by rotary motion It is changed into the thrust of linear motion or the basic mechanical device of pulling force function.

Further, second technical solution of the invention specifically describes are as follows: a kind of chain bar owner will be by: with Y type channel Casing one, sprocket wheel, sprocket shaft, roller tooth chain, each two pieces of guide pad and latch fitting one composition, the chain linkage are made are as follows: every Sprocket shaft respectively puts on a sprocket wheel to key connection respectively, is installed in parallel in casing, and sprocket wheel axis center is away from equal to two roller teeth When the convex tooth mistake section of the inside and outside chain of chain, can phase buckle one by one distance, the output end of two sprocket shafts stretches out in the same direction or oppositely machine Outside shell, two roller tooth chains bypass two pieces sprocket wheel respectively, when by Y type channel and sprocket wheel circular arc, make two roller tooth chains it is interior, The convex tooth of outer plate phase buckle one by one is combined into a chain bar, after chain bar passes through a pair of of the guide pad being symmetrically mounted in casing, Latch fitting gets up chain rod head end " lock ".

Chain bar machine working principle is as a result: when pulling latch fitting to be moved along a straight line, chain bar is drawn two roller tooth chains and is driven It is corresponding by around sprocket wheel rotated with same rotational speed, opposite direction；The convex tooth of inside and outside carrier bar of two roller tooth chains is mutually embedding one by one simultaneously Enter to be engaged, mutually embedding interlocking is got up one by one, and pulling outputs unyielding rigid chain bar, is realized and is carried out straight line fortune by pulling latch fitting Dynamic, the output end for being converted to two sprocket shafts exports the rotary motion of two opposite directions；Conversely, when linear pushing latch fitting, Unyielding rigidity chain bar passes through symmetrical guide pad, when passing through sprocket wheel circular arc and the type channel Y, forms two rollers of chain bar The convex tooth of inside and outside carrier bar of tooth chain one by one thread off by de-embedding, by " segmentation " at two flexible roller tooth chains, while driving two sprocket wheels And the output end of two sprocket shafts is contrary, it is synchronized to rotate, realize by protruding into linear pushing, be changed into two it is reversely rotated Output.

Chain bar machine structure is simple, part yarn, inputs the thrust or pulling force for linear motion, and initial input is usually to draw Power, so the chain bar machine can be described as: pulling force chain bar machine is the torque that thrust or pulling force by moving along a straight line is changed into rotary motion Basic mechanical device.

In the chain bar machine practical application of first and second technical solutions of the invention, it is limited and solid that majority, which stretches out chain pole length, Fixed, when still not stretching out chain bar, there is the roller tooth chain in free state of certain length at chain bar machine input port, is unfavorable for Smooth " out " and " enter " of the roller tooth chain at the input port of casing, it is unfavorable for globality and waterproof and dustproof of chain bar machine etc., is Solve the deficiency:

Further, third technical solution of the present invention specifically describes are as follows: a kind of roller tooth chain coiler is mainly by winding Shell, winding wheel, Scroll, wind spring, crank, handle and positioning pin composition.Wheel case is wound on Scroll, wind spring curling ground installation Between winding wheel and Scroll, one head of wind spring and winding wheel are same fixed, and another head is fixed with Scroll, and is installed along with It winds in shell, one shaft end of Scroll is stretched out outside winding shell, is entangled with being keyed by one end of crank, the crank other end and handle hang down Direct-connected to connect, positioning pin is mounted on crank, and positioning pin can be inserted into the location hole on winding shell surface, makes crank and Scroll phase Winding shell cannot be freely rotated；After extracting positioning pin, hand-holdable handle rotating crank, to drive Scroll, winding wheel one Rotation is played, or when winding wheel is stopped to rotate by external force, continues to rotate crank, achievees the purpose that tighten wind spring.

The working principle that the coiler and the second technical solution chain bar machine are used cooperatively are as follows: will stretch out chain bar machine casing is in outside The roller tooth chain tail end of free state is fixed with winding wheel inner ring, after then extracting positioning pin, holds handle rotating crank, will be certainly It is all involved on the winding wheel of the coiler by the roller tooth chain of state, at this point, the winding shell of coiler has abutted second party technology The casing of case chain bar machine, two casings are connected with, crank is finally continued to rotate, and reach tightening wind spring, repositioning pin insertion It winds in the location hole on shell surface, completes the winding and tightening to the roller tooth chain of free state outside chain bar machine, wind spring Can the length of automatic winding be centainly greater than the nominal length of chain bar machine output chain bar, which can be described as elastic coiler.

Longer for worm and gear chain bar machine output chain pole length, the winding length ability of elastic coiler cannot reach Make, " synchronization " coiler can be used and cooperate with it:

Further, 4th technical solution of the invention specifically describes are as follows: a kind of coiler mainly by: winding shell, winding wheel, Scroll, wind spring, worm gear, worm screw composition.The parameters such as the worm gear of the coiler, the rotation direction of worm screw, modulus, the number of teeth, will be with its institute The ipsilateral worm gear of the worm and gear chain bar machine being used cooperatively, the parameters such as rotation direction, modulus, the number of teeth of worm screw section are identical, wind spring can from Dynamic winding length is equal to the difference that winding wheel maximum outer ring garden perimeter subtracts minimum inner ring garden perimeter；Wheel case is wound in Scroll On, it is mounted between winding wheel to wind spring curling, one head of wind spring is fixed with winding wheel, and another head is fixed with Scroll, It is keyed one worm gear of set on Scroll again side by side with winding wheel, worm and wheel engagement is installed along in winding shell；Snail Bar is designed to three sections of forms, and one section is the input section stretched out outside winding shell, and centre is worm screw section, and the other end is in cannulated sleeve form For output end.

It is somebody's turn to do the working principle that " synchronization " coiler and worm and gear chain bar machine are used cooperatively are as follows: will stretch out outside chain bar machine casing It is fixed in the roller tooth chain tail end and winding wheel inner ring of free state, then holds the input section rotation of worm screw, it will all freely The roller tooth chain of state is all involved in winding wheel, continues to rotate worm screw, reaches tightening wind spring, while by the input shaft paragraph key of chain bar machine In the deferent segment of the cannulated sleeve of the worm screw of connection ground insertion coiler, by the winding shell of coiler and worm and gear chain bar machine Casing, which is connected with, to form a whole, because winding wheel is the winding of spiral reduplicative forms to roller tooth chain, so, winding When wheel, revolving speed is variation, to adapt under coaxial worm and gear Synchronous Transmission mode, the actual speed and worm and gear of winding wheel Differential existing for the chain wheel speed of chain bar machine, thus be adjusted and kept using shorter wind spring roller tooth chain into or when moving back The tensioner degree needed, because using coaxial, synchronous input form.The coiler is known as: synchronous coiler is completed to worm gear snail The input roller tooth chain of bar chain bar machine is wound and is tightened functional machinery device.

Further, according to conventional chains specification, kind form, under the premise of not changing chain specification, use is multiple rows of The chain form of mode can enhance the strength character etc. of chain, so, the 5th technical solution of the invention specifically describes are as follows: uses The chain bar machine of multiple rows of roller tooth chain, a kind of chain bar owner will be by: casing one, multiple chainwheel, sprocket shaft with Y type channel, Multiple rows of roller tooth chain, each two pieces of multiple rows of guide pad and each composition of left-handed worm gear, dextrorotation worm gear, worm shaft, latch fitting.Its is whole Body structure and working principle, in addition to being changed to multiple rows of roller tooth chain with single roller tooth chain and correlated parts accordingly change outside, other It is all identical as the first technical solution embodiment of the invention, so the chain bar machine can be described as: multiple rows of chain bar machine.

On the basis of the chain bar machine of first technical solution of the invention, expand the convenience of its application, is rolled using duplex form Sub- tooth chain is one of most basic chain bar machine form, duplex roller tooth chain be by two side by side single roller tooth chain be separated by a spacing From every chain link (or being separated by several chain links) shares a long chain pin and forms " duplex " roller tooth chain.
