Abstract
When supplied yarn (10) is coiled into a cross bobbin (11) at a constant speed, the tension fluctuation of the yarn is compensated, and the given limiting value of yarn tension can not be surpassed through the change of coiling speed. In order to compensate the periodic tension fluctuation of the yarn, a first-stage regulating device (96) is arranged; in order to compensate the specified ranges of the deviation of the yarn tension, a second-stage regulating device (51) is arranged.
Description
The present invention relates to a kind ofly be wound into the device of cross-wound bobbin with the constant speed yarn, this device has a friction roller that drives cross-wound bobbin with its circumference; Two control system, the yarn tension fluctuation of its first control system compensating for periodic, its second control system has two bevel wheeies, is used to change the actuating speed of friction wheel so that the variation of compensation yarn tension; And one determine the second control system speed change and the transfer element that connects with first control system.Two bevel wheeies of second control system can move axially, but and reposition under the effect of reset attachment.
The coiling of this cross-wound bobbin (cone) by friction roller garden Zhou Chuandong, therefore, will guarantee that in transmission range linear velocity constant is constant.When supplying yarn consistently, as in rotor spinner and some up-coiler, coming to this.Only need to compensate the different traverse distance of cotton yarn, generally adopt this simpler method, for example adopt the guide rail of a bending to realize at the Width of bobbin.When coming transmission by the segment section on the bobbin length, that can have nothing in common with each other in work area and district's exterior portion diameter, has therefore caused the difference of linear velocity.Become particularly outstanding for the tapered bobbin problem, also there is unequal this factor of the distance of yarn traverse on the bobbin Width in tapered bobbin, this is the vary in diameter that causes owing to the bobbin tapering, so whenever around a commentaries on classics, the coiling length of yarn all tangible fluctuation can occur.The bobbin of coiled can be uneven like this, also can cause layer to come off, and the further processing of back is met difficulty, up to broken yarn takes place.
In order to compensate the difference in length of yarn, such suggestion had been arranged, i.e. bobbin speed change transmission (GB-Al, 249,247).For the yarn tension fluctuation that takes place, stablize by balance or one or more spring.But verified, when taking place, the yarn tension fluctuation swings on the position therebetween around yarn speed control shift fork, and this swing can further cause the fluctuation of yarn tension.
Task of the present invention is for avoiding above-mentioned shortcoming that corresponding device thereof is provided, and the yarn of reeling equably, particularly taper cross-wound bobbin are reeled and mechanism's simple structure compactness them with uniform yarn tension on each station.
This task is to solve like this, and transfer element attaches a stop tab, can determine the initial position of driving device by this stop tab, has determined the maximum transmission ratio of driving device on the initial position.Guarantee the fixing initial position of driving device like this, and promptly eliminated unsettled transmitting ratio.
Preferably except that adjustable stop tab, a position shift fork by the transfer element of reset attachment drive is arranged, verified, it is practical that adjustable stop tab is placed on the shift fork of position.
Can use a retracing spring as reset attachment in the present invention very simply, especially garden cone pulley conical surfaces also is used for as reset attachment.The conical surfaces of driving wheel and flower wheel is given power of transfer element, makes transfer element turn back to initial position.In order to realize this purpose, driven cone pulley is contained on the wheel shaft, this wheel shaft and main driving axle relative tilt, and initiatively the garden cone pulley just is contained on this root main driving axle.The degree of dip of wheel shaft is adjustable simultaneously.Its advantage also has adjustable wheel axle to be contained on the lever in addition, and lever has the eccentric adjustment pin.
Two bevel wheeies are selected different taperings for use, if at this moment transfer element has different taperings and is complementary with the tapering of two cone pulleys respectively, this is to have very much a preceence.Reset attachment also has a subsidiary benefit to be, transferring power is come in the transfer element different position that moves around between two cone pulleys, has so just avoided excessive wearing and tearing on the contour of a certain garden of garden cone pulley.
In order to prevent such danger to occur, promptly the tail yarn that tapered bobbin diameter one end forms at the beginning when the coiling tapered bobbin falls into variable-speed drive, preferably at minor diameter one end variable-speed drive is installed.
As " friction roller ", this part should be understood that in meaning of the present invention, by it garden week drive tapered bobbin, and whether let it be length the same with the whole length of bobbin or wherein a part just.
The present invention structurally is very simple, the reliable space of saving on function.Regulate yarn tension and coiling speed ratio easily, this device still can be controlled under the situation of high-speed winding exactly, therefore can wind good cylindricality and taper cross-wound bobbin.
The detailed explanation of each embodiment further specifies below in conjunction with the accompanying drawings.

The wind2 (1) that at first will introduce and provide in Fig. 1 is the part in the rotor spinner, is used for coiling taper cross-wound bobbin (11).Certainly this invention can be used on the spinning machine of other type equally, and what draw among the figure is coiling station or the wind2 (1) that forms cylindricality or taper cross-wound bobbin (11).
As shown in Figure 1, each wind2 (1) is formed mainly due to following parts: bobbin support (2), independently axial immovable friction roller (3), one drives that friction roller (3) rotates and axial immovable main driving axle (4) through adjustable speed-changing driving device (5).
As shown in FIG., bobbin support (3) has two bobbin arms (20) and (21), in order to the bobbin (22) of laying tapered bobbin, with yarn (10) coiled taper cross-wound bobbin (being cone) (11), the driving of bobbin is realized by friction force by friction roller (3) on this bobbin.
Friction roller (3) is installed on the main driving axle (4) with two antifriction-bearing boxs (30) and (31), and friction roller can freely rotate, an end fixed engagement of gear (71) and friction roller (3).Gear is the part of the straight gear transmission device (7) between variable-speed drive above-mentioned (5) and the friction roller (3).
Main driving axle (4) is a common axis, a plurality of wind2s adjacent one another are (1) are housed, the length of main driving axle (4) is consistent with the number of wind2, for each bobbin (11) can be driven independently, friction roller (3) is by main driving axle (4) direct drive, but drives by connecting in the middle of the adjustable speed-changing driving device (5).
Variable-speed drive shown in Figure 1 (5) has an adjustable cone pulley transmission device (6) and a nonadjustable straight gear transmission device (7).The one active cone pulley (60) that installs with main driving axle (4) is arranged in the variable-speed drive (5), and its moves with driven cone pulley (62) through transfer element (61).As shown in the figure, transfer element (61) is made the form of regulating ring, and it can be parallel to the appearance profile line of cone pulley (60) and (62) regulates, and also will introduce as the back.Cone pulley (62) is contained on the wheel shaft (65) by means of antifriction-bearing box (63) and (64), and wheel shaft (65) is bearing on the bearing (66).What be solidly installed with cone pulley (62) is straight gear (70), it and straight gear (71) engagement that is contained on the friction roller (3).
Transfer element (61) is stirred by shift fork (80), and shift fork (80) is arranged on the corresponding driving device (8).For instance, driving device (8) is a stepping motors that can normally change and reverse, and it is by a miniature gears and the tooth bar engagement that is connected with shift fork (80).Such stepper motor cheaply and not needs to come it is controlled with control apparatus on price, can reduce the expense that is used in the control aspect thus.In addition, such driving device can also the classification of very fine ground, and the transmitting element of practical application (61) is exactly a step-less adjustment.Driving device (8) links to each other with setting device (9), and setting device links to each other with yarn tension sensing (90) again.
As want as described in, constitute first order control setup (96) by yarn tension sensor (90), constitute second stage control setup (51) (see figure 2) by variable-speed drive (5).
Rotor spinner situation shown in Figure 1, yarn (10) is continuously supplied with by spinning apparatus (12), and by means of outlet roller (13) and (14) yarn is drawn from spinning apparatus.Yarn (10) passes a fixing thread-carrier (15) and tension compensating bar (16) then.Yarn (10) is wound on bobbin (22) with yarn and goes up formation intersection cone (11) by means of the reciprocally swinging of fro guiding-yarn device (17) (dotting).
In general (not shown) when the cylindricality cross-wound bobbin of coiled garden is mended bar (16) by means of yarn tension, just can the yarn tension that winding method the caused fluctuation by reciprocal variation be compensated.Yet in coiling taper cross-wound bobbin (11) process, this tension fluctuation changes quite greatly.With a representative type tapered bobbin is example, and the bobbin end diameter was connected variation with the garden week ratio of outside diameter between 10: 16 to 10: 11.This just shows that with fixing compensating part, such as the yarn tension compensation bar is such, and the tension fluctuation that tapered bobbin (11) is occurred in winding process compensates well, is impossible.Sometimes both made is that coiling garden cylindricality bobbin (11) also is difficult.
In front on the device of Jie Shaoing, the yarn (10) of supplying with wind2 (1) is detected by yarn tension sensor (90), each variation of yarn tension is all passed to setting device (9) there, driving device (8) is controlled by the yarn tension variation by this setting device, the transfer element (61) in the cone pulley transmission device (6) is made parallel sliding with respect to cone pulley (60) and (62).Make also corresponding the changing of transmission speed ratio of variable-speed drive (5) thus.Pass to the speed of tapered bobbin (11) by the friction roller (3) of variable-speed drive (5) driving by main driving axle (4), also synchronous change along with the variation of tension force, therefore consider the variation of yarn operation, resulting yarn winding speed remain with for yarn speed, promptly consistent with the speed of yarn (10) being drawn from spinning apparatus (12) by outlet roller (13) and (14).The first order control setup (96) that is made of yarn tension sensor (90) makes yarn (10) to stablize the unmodified tension winding with the second stage control setup (51) that is made of variable-speed drive (5).
From the relative direction of Fig. 1, Fig. 2 has shown bevel wheel (62) transfer element (61) of cone pulley transmission device (6) and the transparent view of shift fork (80).As clearly representing in this drawing, transfer element (61) is a regulating ring that the bus that can be parallel to cone pulley (60), (62) appearance profile axially moves, the size of regulating ring should come like this to determine promptly where all it should be in and can rotate around cone pulley (62) all the time.The internal diameter that has only regulating ring greater than by it around cone pulley (62) external diameter the time, could satisfy such requirement.Regulating ring (61) is in two pairs of pins (800) and (801) sandwich, but can only see pin on one side in Fig. 5.
Wear-resistant especially with regulating ring as transfer element (61), the long service life of comparing with the transfer element of rope and belt and so on.In addition, regulating ring is swift in response to the adjusting motion that gives, and it is had can be along with the timely governing speed promptly of the variation of condition.
Among the embodiment that provides previously, except adjustable speed-changing device (5), also has a nonadjustable transmission device of speed ratio (7).As shown in Figure 1, main driving axle (4) places the inner advantageous particularly of friction roller (3), because just can make friction roller (3) and main driving axle (4) concentric device like this.In addition, by mode shown in Figure 1, adjustable speed-changing device (5) is disposed between main driving axle (4) and the nonadjustable straight gear transmission device (7), its reason is, the driving wheel (garden cone pulley 60) that is supported for fixing main driving axle (4) should leave certain vacant position on friction roller (3) next door, and other being contained in friction roller (3) in the straight gear (71).Because cone pulley transmission device (6) in any case cone pulley have wideer adjustability than the straight gear of a straight gear mechanism (7), so the adjustable cone pulley transmission device (6) of transmitting ratio is arranged in the centre of main driving axle (4) and nonadjustable another transmission device of transmitting ratio (7).
The front is introduced embodiment and is had the two-stage speed ratio, also can replace with one-level speed governing or multistep speed regulation fully certainly.
Owing to the cause of its tapering, although the cireular frequency of each point is identical on its each length direction, linear velocity is different when being driven for taper cross-wound bobbin (11).Yarn (10) on the bobbin (11) each point linear velocity and friction roller (3) along its length has difference in the linear velocity of this point, and this makes yarn (10) bear bigger friction yarn (10) is had a negative impact.So as a kind of corrective measure, as shown in Figure 3, friction roller (3) is done roll surface at the centre portion of its length areas with a lasso (33).Other length field of friction roller (3) is also just little to the friction coefficient of yarn (10), and these parts only play the effect of rest.Texturing line or both dual-purposes are gone up in material or surface that lasso (33) surface should be selected to suit, do like this for bobbin (11) and can play good booster action.There is not dependence in other length field that only plays the rest effect on lasso (33) surface and the friction roller (3) in the variation of speed, so when determining its size, pass to bobbin (11) as long as can guarantee that lasso (33) will rotatablely move.
Because for taper cross-wound bobbin (11), sometimes may wish that the tail yarn stays bobbin (a 22) end (Fig. 1) all the time, it is bobbin (11) major diameter one side, loose thread so just might occur and fall the problem of going in the variable-speed drive (5), the result not only can make the tail yarn come off from bobbin (22), but also can disturb the operation of variable-speed drive (5).As a kind of ancillary method, it is such to press Fig. 3, and variable-speed drive (5) is contained in bobbin (11) minor diameter one side, and bobbin (11) is inserted on the bobbin support (2).
Friction roller (3) also can drive by outer garden week, and friction roller (3) has a lasso (33), and it not only can also can drive friction roller itself by variable-speed drive (5) in order to drive bobbin (11).Therefore for instance, replace straight gear (70) also to be fine with friction wheel in Fig. 1, friction wheel and lasso (33) are close together, and drive friction roller (3) with this.
Among the embodiment of Jie Shaoing, the transfer element (61) and the second stage control setup (51) of cone pulley transmission device (6) are all regulated by setting device (9) in front.The adjusting of this respect is that yarn tension sensor (90) is undertaken by electric adjusting, that is to say to realize by first order control setup (96).Here the version of yarn tension sensor (90) how, do not play what effect basically.Therefore for instance, yarn tension sensor does not contact yarn and can work yet, and the tension force of yarn can be tried to achieve or try to achieve with other method by the function of survey tension force numerical value.
In the version shown in Figure 2, transfer element (61) is mechanically regulated by yarn tension sensor (90).Yarn tension sensor (90) is for lightly made of plastic, and it has a feeler lever (91), is contained in swingably on the little axle (93) by bracket (92).Little axle (93) by bearing (94) rest.Feeler lever (91) is withstood by a torque spring (95) and the effect by this torque spring (95) remains feeler lever and contacts with yarn (10), so the size of yarn tension is just depended in the swing of feeler lever.For this purpose, an end of torque spring (95) is fixed on the bearing (94), and the other end is fixed on the bracket (92).
Bracket (92) middle side part outside the end face (920) of its garden shape is equipped with a pin (921), it inserts in the slotted hole (820) of fritter spare (82), this fritter spare (82) is parts of guide rod (81), and it links up feeler lever (91) and shift fork (80).Fritter spare (82) is contained on the push rod (83), and fritter spare (84) also is equipped with in the other end of push rod.The piece spare of other end (84) links to each other with another root drive link (86) by the elbow pole (85) that is contained on the frame (18), makes drive link (86) and main driving axle (4) keeping parallelism by means of guide (87).Adorn shift fork (80) on the drive link (86), having two pairs of pins (800) and (801) (can only see a pair of pin sometimes) to stir transfer element (61) (see figure 1) of bevel gear drive unit (6) on it.
In the version shown in Figure 2, a slotted hole (820) of opening according to the sense of motion of push rod (83) is arranged on piece spare (82), when the yarn tension fluctuation is little, can not regulate transfer element (61) immediately like this, so when compensating less tension fluctuation, yarn tension sensor (90) can not regulated transfer element (61).As what introduced, yarn tension sensor (90) constitutes first order control setup (96) and is used for the fluctuation of compensating for periodic yarn tension, and this tension fluctuation is a (see figure 1) of impelling yarn (10) to swing back and forth and cause owing to fro guiding-yarn device (17).When just having begun coiling when coiling tapered bobbin (11) or on the bobbin (22) at sky, this first order control setup (96) is enough to be used for bearing the tension fluctuation of yarn fully.
Reeling, yarn will be filled in lasso (33) with the space between external friction roller (3) and the bobbin (11) (seeing from (110) to (111) this section among Fig. 3) after a bit of time.So the garden week of bobbin is bigger than transmission those a bit of (112) in (110) arrive (111) this segment limit, so that, in bigger (110) and (111) scope of circumference, understand the more yarn (10) of coiling when the transmission speed of cross-wound bobbin (11) and its transmission range (112) when adapting.This just makes the tension force on the yarn (10) increase, so yarn tension sensor (90) just swings among this segment limit of II-III (see figure 4) in original scope I-II.At this moment pin (921) drives piece spare (82) and passes through the control of guide rod (81) realization to transfer element (61), so the also corresponding change of the speed ratio of variable-speed drive (5).So when exceeding the pre-determined yarn tension limit, the winding speed of yarn (10) will descend.Device (90) and the piece spare (82) of yarn tension limit by the yarn tension sensor comes definite.Thereby the fluctuation of yarn tension returns to again in the original variation range.Yarn tension sensor (90) moves around in this segment limit of I-II again, and the yarn tension fluctuation that the cycle changes in this interval is compensated by fork, and at this time adjustable transfer element (61) has guaranteed higher winding speed.
Therefore variable-speed drive (5) just becomes the second stage control setup of having mentioned the front (51), is used for compensating the amplitude offset of yarn tension fluctuation.
Because amplitude offset is relevant with the diameter of bobbin (11), second stage control setup (51) can be different with the version of having introduced, can be independent of first order control setup (96) and come work, the recruitment of bobbin diameter is depended in the adjusting of second stage control setup (51) at this moment.If second stage control setup (51) can be followed first order control setup (96) and regulate when surpassing the yarn tension scope of stipulating, just can control yarn tension and tube quality very accurately.
To the out-of-action yarn tension fluctuation range of second stage control setup (51),, can regulate according to Fig. 2.As represented among this figure, in order to obtain desirable adjusting accuracy all the time, being parallel to push rod (83) on piece spare (82) has one to regulate bolt (821), and it reaches in the slotted hole (820) always and goes.Changing simultaneously by size of adjusting this adjusting bolt (821), slotted hole (820), the action sensitivity of this device also changes thereupon.
If the variation of every bit yarn tension has all required to regulate action, then can adjust accordingly or substitute slotted hole (820) and match with pin (921) to adjusting bolt (821) with post hole, a garden.
In order to make on out-of-run winder station, feeler lever (91) though remain static also can move, and backing pin (940) is housed on bearing (94), and two piece spares (82) are not captiveed joint with push rod (83) with (84).As shown in Figure 2, (from viewer's direction) all has resilient coupling (830) and (833) of usefulness pressure spring formation in each piece spare (82) and (84) front, headed on by the regulating ring (831) and (834) that are enclosed within on the push rod (83).Stop tab (832) and block (835) also are housed on piece spare (82) and (84).
For the structure of introducing, resilient coupling (830) is all passed through in each action of feeler lever (91) and (833) pass to drive link (86).
According to Fig. 2, yarn feeler lever (91) is positioned at the next door of backing pin (940).If yarn feeler lever (91) is just being pushed away by backing pin (940) and swinging, that pin (921) is done is garden Zhou Yundong, and the component motion that is arranged in the pin (921) of slotted hole (820) is limited on the direction of joint piece (830) reels.When drive link (86) when maintaining static, because this station is not reeled, so can not regulate transfer element (61), so the piece spare (82) that cooperates with pin (921) just can only drive push rod (83) by resilient coupling (830), till baffle ring (835) is run into piece spare (84).The continuation campaign of piece spare (82) is limited by resilient coupling (830).
When feeler lever (91) moved towards backing pin (940) opposite sense, piece spare (82) was blocked by block (832).If drive link (86) is plugged, then piece spare (84) can not be along with push rod (83) motion, so the continuation campaign of push rod (83) is limited by elastic coupling spare (833).
Device through remodeling provides in Fig. 3, by means of the device of this remodeling equally can compensating for periodic the yarn tension fluctuation and prevent that by changing winding speed yarn tension from surpassing the limit of regulation by way of parenthesis.First order control setup (96) have a yarn tension sensor (90) (with embodiment illustrated in fig. 2 in provide identical) it can rotate and be given by torque spring (95) and tighten around little axle (93).Yarn (10) by outlet roller (13) and (14) guiding, guides (see figure 4) in the top of feeler lever (91) by the thread-carrier (150) that is contained on the frame (18) in feeler lever (91) below.
With the guides of yarn tension sensor (90), a stop tab (832) is arranged on the push rod as push rod (83).Block (832) can be regulated, and it has such effect on push rod (83), be that yarn tension sensor (90) (see figure 4) yarn tension fluctuation of periodically occurring of motion compensation freely in this section of I-II interval changes, and can not collide on the block (832).The adjusting of block (832) on push rod (83) therefore also just determined the boundary of interval I-II and interval II-III, and also determined the limit of yarn tension thus.
Push rod (83) is guided by the guides (880) of elbow pole (88) one ends, and is being supportted by regulating ring (834) and resilient coupling (833).Elbow pole (88) is contained on the frame (18), and block the pin (802) of shift fork (80) with its empty end, there are two slotted holes (803) and (804) and two guide bolt (180) and (181) that are contained on the frame (18) to make shift fork be parallel to the main driving axle of friction roller (3) (4) motion on the shift fork.
Block (805) is housed on the shift fork (80), and it is used with the position block (182) that is fixed on frame (18).In described embodiment, in the middle of this two block one, promptly the block (805) on the shift fork (80) can be regulated, so do this block with an adjusting bolt.Also has a reset attachment (89) in addition.According to shown in Figure 3, it is a retracing spring (890), and one of spring is fixed on the frame (18), and the other end is fixed on the shift fork (80).
Because the effect of reset attachment (89) makes shift fork (80) and transfer element (61), at first order control setup (96) not in second stage control setup (51) transfer function power, be in the initial position, this initial position is determined by block (182) and (805).Original determine directly to have influence on determining to variable-speed drive (5) transmission speed ratio.So the size of tensile stress just depends on the position or the adjusting of position block (182) or (805) on this station.Just can must not determine the maximum transmission ratio that surmounts, the i.e. maximum line velocity of bobbin (11) by regulating block (805).
When bobbin (11) constantly when big, owing to the expansion in (110) and (111) these two sections intervals has surpassed normal ratio, caused the winding speed rising thus, this just makes the tension range of the yarn tension overshoot that periodically occurs, at this moment yarn tension sensor (90) will react to some extent, is displaced in interval II-III.Yarn tension sensor (90) is run into block (832) and upward and by push rod (83) and elbow pole (88) shift fork (80) is lifted from block (182) there.Shift fork (80) leaves its initial position so promote transmission regulating ring (61), is moved to the major diameter district of cone pulley (60) and the minor diameter district of cone pulley (62).At this moment reduce the rotating speed of the bobbin (11) that drives by friction roller (3), thereby avoided yarn tension to surpass specialized range.Thereby reduced the linear velocity of the bobbin (11) that rotates by friction roller (3).At this moment winding speed descends, and yarn tension weakens, and yarn tension sensor turns back to interval I-II again.Because the effect of retracing spring (890) makes shift fork (80) have such trend, transmission regulating ring (61) is turned back on the initial position.The linear velocity of bobbin (11) is improved, make the fluctuation of yarn tension be offset to II-III interval thereby cause yarn tension to rise again.This fluctuation will last till till kinetic balance occurring between I-II and the II-III district always.Percentum diameter difference between these several sections is just more and more littler in (110) on the bobbin (11), (111) and (112) when bobbin constantly increases in addition, so the skew of yarn tension sensor (90) is also more and more littler.
Reset attachment (89) also can use among the embodiment that is introduced in Fig. 1 and Fig. 2.It has been avoided when yarn tension sensor (90) leaves interval I-II, transmit the mobile excessive of regulating ring (61), to such an extent as to producing yarn tension thus descends, and must oppositely regulate yarn tension sensor (90) at once, for example, use connector (830) and regulating ring (831) (Fig. 5).Also such danger can occur at this, i.e. yarn tension fluctuation finally no longer can be compensated, but fluctuates severely more more.This phenomenon has only with reset attachment and could prevent reliably.
According to Fig. 3 and Fig. 4 yarn tension sensor (90) flange (900) is arranged, it is basic parallel with friction roller (3) with main driving axle (4).This flange (900) use that can match with the arm of unillustrated fender guard, fender guard can for example when beginning to spin, be put yarn tension sensor (90) on the position of IV from the yarn road along machine run always.Because shift fork (80) can not be realized this motion by block (182), so be contained in push rod (83) and transmission regulating ring (61) connector (833) between the shift fork (80) just, one accessory channel arranged when putting the position of IV at yarn tension sensor.
What Fig. 5 drew is the structure of another kind of reset attachment (89).Cone pulley (62) is installed on the wheel wheel (65), and it has a bevelled angle with respect to the main driving axle that cone pulley (60) are housed (4).Although cone pulley (60) has identical tapering with (62), but because this angle of inclination converges at some cone pulley (60) and extension line of the side surface of (62), therefore have a component P to act on the transmission regulating ring (61), this power can make regulating ring (61) turn back to the initial position.
By shown in Figure 5, convergent angle (a) can adjust, and at this moment cone pulley (62) is contained on the elbow pole (68) by middle lever (67) by the angle.Elbow pole (68) can have a slotted hole (681) around little axle (680) swing on its free end, eccentric adjustment pin (682) is stuck in the hole.Middle lever (67) withstands on the compression spring (670), and spring is fixed on the frame (18) by rights.
(angle α) obtains like this according to Fig. 6 convergent angle, and promptly two cone pulleys (60) have different cone angles with (62) and (see angle β
1And β
2), component P acts on the transmission regulating ring (61), and this component makes regulating ring turn back to the initial position.In order to ensure transmission ring (61) long service life, the tapering of the interior garden side face of ring and outer garden side face is identical with two bevel wheeies (60) and (62), therefore transmits the tapering of regulating ring (61) and being complementary of cone pulley (60) and (62).
Above-mentioned introduction points out that multiple mode conversion can be made in the theme of being applied for, can continue remodeling by feature exchange or equivalent substitute and combination with one another, and these all belong to scope of the present invention.For instance, can replace the block (805) and (182) that are attached to shift fork (80),, transmission ring (61) is blocked, so this block just defines transmission ring (61) maximal regulated stroke in one direction with a block.
