Background technology

In existing rolling/initiative rolling-unrolling machine, if there is employing cylinder/hydraulic actuating cylinder to realize the swelling function of swelling watt, all do not have auto-lock function.That is, when cylinder/hydraulic actuating cylinder or the gas circuit that is connected with it/hydraulic tubing occured to reveal, the air pressure or the hydraulic pressure that act in the cylinder body on the piston descended, and swelling watt will lose enough tension forces.When swelling watt loses enough tension forces, for the machine of vertical unreeling/rolling, still can owing to the deadweight of material volume, the material volume still can be positioned in the swelling watt (or being referred to as reel).But for level unreel/machine of rolling for, be easy to cause the material volume to fly out or expect that volume scatters owing to rolling/tension force when unreeling or the reasons such as whirling vibration of machine, and in case loose volume occurs, then generally raw material can't be reverted to original state again, so this just causes serious safety misadventure or causes serious wastage of material.

If but the cylinder/hydraulic actuating cylinder that will have simply auto-lock function is applied to and unreels/the winder field, can there be following problem again: 1, the self-locking of cylinder/hydraulic actuating cylinder only is to keep the position of throw rod motionless, and can't guarantee to provide a lasting constantly application force so that the swelling watt inboard that has enough tension forces to come distensible material to roll up, watt can not retract and only satisfy swelling, it only is the simple passive non-active tension force of bearing force between swelling watt and the material volume inboard, be actually like this and rise not tightly, for example patent application 201010138295.0 disclosed spool material retractable feeders just do not adopt self-locking cylinder to hold out against I-beam wheel; If the internal diameter of 2 material volumes is not completely unified, internal diameter is less than normal slightly, will cause the piston of self-locking cylinder/hydraulic actuating cylinder full action to put in place, self-locking device can't start, internal diameter is bigger than normal slightly, will cause the piston full action of self-locking cylinder/hydraulic actuating cylinder to put in place after, self-locking device starts, it is inboard that swelling watt also can't the distensible material volume, also or should have more than is needed self-locking cylinder/hydraulic actuating cylinder.

So self-locking cylinder/hydraulic actuating cylinder is applied to unreel/the winder field, avoid leaking gas or leakage on the impact of machine safety in operation and reliability, be that those skilled in the art thirsts for solving and the problem of failing to succeed always.

See also Fig. 1, Fig. 5, the cylinder bar of start cylinder 33 is hinged with the side arm end of V font connecting panel 35 by connector 36.Correspondingly, the side arm of the V font connecting panel 35 of arm structure both sides is arranged in a crossed manner, namely two connecting panels 35 are mutually vertical, in the space of the V font inside bottom of each connecting panel 35 between the V of another connecting panel 35 font two side arms, utilize space between each V font two side arms to hold the bottom of another connecting panel and connection wye 34 hinged, that be positioned at tie rod end with it, this connection wye 34 is threaded in the inner end of pull bar 17.When so the size of connecting panel should guarantee that start cylinder bar is released, the bottom of two V fonts can not interfere, and the width between the V font two side arms should reach greater than the thickness of connecting panel the length of the bearing pin of the Y-shaped connector 34 that is used for hinged V font connecting panel bottom and tie rod end simultaneously.

Connection wye 34 is threaded in the inner end of pull bar 17, connection wye 34 adopts the jam nut locking that is connected on the pull bar 17, between jam nut and Y-shaped connector, install stop washer (GB/T 858-1988) additional, can limit connection wye with respect to the rotation of pull bar.In other words, owing to being that the plane is hinged between connection wye and the connecting panel, and connecting panel can not rotate, thus connection wye also can not rotate, so also just limited the rotation of pull bar.

Because exoskeletal accurate after-combustion steel coil strip is different from the wide cut steel coil strip, wide cut steel coil strip width can reach about 1m even be more, and the width of wall scroll steel band and the Thickness Ratio of steel coil strip are larger, are not prone to the problem that steel band scatters to the side.And for the flux-cored wire steel coil strip, width of steel band is 10～20mm, and in arbitrary section, one deck steel band generally has the steel band more than 20, and the probability that such steel coil strip generation is scattered to the side is more much bigger than wide cut steel coil strip.So need to baffle plate be set in the steel coil strip both sides, in case the steel band in the steel coil strip scatters to the side.

Drive socket 28 is connected with chain drive, and chain drive is driven by motor reducer 61, and motor reducer 61 is installed on the casing.This unreeling machine not only can carry out initiatively unreeling operation can also carry out the rolling operation.

In the present embodiment, the connection structure of casing and base, similar with disclosed connection structure among the patent documentation CN201525655U, the utility model does not repeat them here.

Such as Fig. 6 a～Fig. 6 b and shown in Figure 1, the principle of work of the present embodiment is:

One) shown in Fig. 6 a the first half, before the steel belt for lifting volume, the displacement cylinder group of respective side is shunk, displacement cylinder drives pull bar by connecting panel and stretches out, circlip for shaft on the pull bar promotes the first inner ring sleeve and the second inner ring sleeve, the second inner ring sleeve promotes the inner ring of two-direction thrust bearing, and promotes roller bearing end cap by two-direction thrust bearing.Because roller bearing end cap and plain bearing chamber are connected, the plain bearing chamber is also along with roller bearing end cap is outwards mobile together, the outdoor gusset of plain bearing that is packed on the plain bearing chamber is also thereupon outwards mobile together, angle between swelling connecting rod and the axis reduces, angle between support link and the axis reduces simultaneously, the circular arc of swelling watt edge take the distance between two hinge-points of support link and swelling connecting rod as radius is outwards mobile, and the external diameter of simultaneously swelling watt also dwindles thereupon.When the outer gusset of the inner reinforced plate of swelling watt and turnbarrel contacted, the external diameter of swelling watt was retracted to minimum value, and start this moment cylinder still may not shrink and put in place.

Because the axial location of inboard registration device on swelling watt gusset can be regulated, so before the steel belt for lifting volume, need to adjust the position of determining inboard registration device.If directly steel coil strip is placed in the swelling watt, the standard of neither one location, the workman determines the position of steel coil strip entirely by rule of thumb, so very possible bigger than normal or less than normal, if steel coil strip is excessively near apart from the outer end, will cause swelling watt after swelling, the inboard of steel coil strip still can't touch on the square tube of Internal baffle, steel coil strip does not have the location, side, and the steel band that keeps to the side most still might subside.If inboard registration device is excessively far away apart from the outer end, although can utilize the square tube of Internal baffle accurately locates the side of steel coil strip, but can increase the distance of the friction of steel coil strip and swelling watt support, for the steel coil strip that does not have paper web, this is with the most inboard steel strip surface in the severe wear steel coil strip, and the wire feed when administration core welding wire is produced follow-up drawing work or use brings difficulty; For the steel coil strip that has paper web as the inner tube of a tyre, although there is not the problem of the steel strip surface of wearing and tearing, also can strengthen the wearing and tearing to recycled paper web.And except wear problem, when steel coil strip and swelling watt relatively moved, friction force needed the application force of start cylinder to overcome, and undoubtedly can increase the load of start cylinder, might cause the increase of start cylinder size.After having increased inboard registration device, can be after once adjusting to the right place, it is carried out fastening, just a good reproducibility has been arranged during each upper volume, the position reference of accurate positioning need not again to adjust, and can avoid above-mentioned problem.

Two) steel coil strip is placed in the upper and axial location of swelling watt after, the start cylinder stretches out, the connector on the start cylinder bar drives connecting panel, and then drives pull bar and retract, the nut of tie rod end compresses disc spring sleeve, disc spring sleeve compression belleville spring group.Because the belleville spring group is not in compressive state when pull bar stretches out fully little when amount of compression will be more than the lifting steel coil strip in other words, so start this moment cylinder only is by pull bar compression belleville spring group, and do not cause other variations, for example can suppose that the distance between this moment dish spring support ring and first shaft shoulder is 5mm, state is shown in the bottom of Fig. 6 a is divided at this moment.Certainly, if in order to reduce space in the casing and the start cylinder of selection of small stroke, swelling watt inner reinforced plate still is suspended from the outer gusset of turnbarrel in the time of can causing the contraction of start cylinder to put in place, both can not dock, if will expect in this case volume is placed in the swelling watt, can move plain bearing is outdoor by the swelling connecting rod, by two-direction thrust bearing, the first inner ring sleeve, dish spring carrier ring with force transmission on dish spring group, dish spring group is compressed.Certainly also might be above the two combination, i.e. the swelling watt inner reinforced plate segment distance that descends, after one section of dish spring group compression, swelling watt inner reinforced plate falls to placing on the outer gusset of turnbarrel, when then pull bar moves inward, again dish spring group is continued one section of compression.

When compressive force suffered on the belleville spring group reaches steel coil strip need to be risen required application force the time, the plain bearing chamber is (this power is delivered on the plain bearing chamber by dish spring support ring and two-direction thrust bearing) under the elastic force effect of belleville spring, in turnbarrel, move, and then by swelling connecting rod and support link swelling watt is propped up, this moment, the center of gravity of steel coil strip constantly rose.

Because the angle of swelling watt swelling when swelling connecting rod and support link are greater than these two connecting rods and have just begun the lifting steel coil strip with respect to the angle of axis when putting in place, so stressed (belleville spring stressed) during swelling on the connecting rod is less than the power when just beginning the lifting steel coil strip, the length of belleville spring is greater than its length when just beginning the lifting steel coil strip, in lifting the process of steel coil strip, belleville spring is in fact to discharge its amount of compression constantly, distance between dish spring support ring and first shaft shoulder is 1.5mm at this moment, and this moment, state was shown in the first half of Fig. 6 b.This moment, dish spring group still had certain compression surplus.So watt with steel coil strip after the complete swelling, the start cylinder still continues to release a segment distance in swelling, pull bar continues to shrink inwards, disc spring sleeve compression belleville spring group.Until reach start cylinder stroke, the lock of start cylinder interior with lock is locked the start cylinder, prevents that the start cylinder from losing thrust because of gas leakage, causes expecting to roll up the accident that flies out, distance between dish spring support ring and first shaft shoulder is 3.5mm at this moment, and this moment, state was shown in the latter half of Fig. 6 b.Be belleville spring by the length of another compression in the swelling watt length that start cylinder bar continues to stretch out after the complete swelling with steel coil strip, then this length is 2mm.When the parts such as start cylinder, connecting panel, connector, pull bar are installed more accurately, this length is needed just less, and the second-compressed amount of spring is also just less, and the pressure during final initiative rolling-unrolling machine operation on the dish spring group is also just less.For above-mentioned reasons, in initiative rolling-unrolling machine when operation,, in other words, the axial force after the steel coil strip swelling is less, and after machine run got up, the two-direction thrust bearing in the outside and inboard thrust baring stressed also less was conducive to improve the thrust baring life-span.

The generation of second-compressed amount is not only in order to remedy the error when installing, and has the effect that tension force is provided concurrently.Because in fact in the swelling watt process that constantly struts, the swelling watt bearing capacity for the material volume also only is to equal to expect the gravity rolled up, then the elastic force on belleville spring this moment also with this bearing capacity to corresponding.If there is not second-compressed, that swelling watt will be the same (owing to the geometric relationship between swelling connecting rod, swelling watt, support link and the pull bar with not using dish spring group to the tension force of material volume, can not produce larger tension force, otherwise will cause structural damage) use so the advantage of disk spring group to give prominence to.And the generation of this second-compressed amount, then over against the generation of having answered additional tension force, and this tension force can not disappear because of the gas leakage/leakage of start cylinder, and this additional tension force exactly, guaranteeing can have enough friction force between swelling watt and the material volume the most inboard (or material roll up paper web), raising speed/reductions of speed that control honest material convolution turns etc. have improved Security of the system and reliability.For example, the weight of material volume is 1000 kilograms, when swelling watt will be expected the complete swelling of volume, application force on the dish spring group is 800 kgfs, because the second-compressed of dish spring group, application force on the dish spring group has increased again by 320 kgfs, increased again so the tension force of 400 kgfs between swelling watt and the material volume inboard, and this has just increased swelling watt and material and has rolled up friction force between the inboard.

Owing to adopting initiative rolling-unrolling machine or the winder of swelling watt distensible material volume inner core to be different from I-beam wheel unwinding and rewinding machine.The material of I-beam wheel unwinding and rewinding machine volume is placed on the I-beam wheel (or being referred to as drum), and the rotative speed of I-beam wheel is to embed in the hole in the I-beam wheel by the finger on the unwinding and rewinding machine, stirs I-beam wheel and rotates to regulate its rotating speed.And adopt the rotating speed of the confidential adjusting material volume of material retractable of swelling watt to regulate its rotating speed by the friction force that swelling watt and material are rolled up between the inner core, and friction force is determined by tension force and friction coefficient, and friction coefficient be immobilize moving, so can only improve friction force by increasing tension force.

In case the piston movement of self-locking cylinder puts in place, the application force that the cylinder of the initiative rolling-unrolling machine of the existing form of employing externally applies is and overcomes the required corresponding dish spring force of bearing capacity of material volume weight, and for example the piston area of cylinder is 314cm ², air pressure is 4kgf/cm ², then the cylinder power that can externally apply in theory is 1256kgf, but in fact can only externally apply 800kgf after the self-locking, remaining 1256-800=456kgf can only act on the cylinder bottom of cylinder.For example the friction coefficient between tensioner watt and the material volume is 0.3, and then the friction force of every swelling this moment watt can only be 300kgf.If tensioner puts in place before self-locking, cylinder no longer moves, and cylinder on the contrary can outwards be exported the 1256kgf application force, but has not had self-locking, in case cylinder leakage tester will be easy to expect to roll up the accident that flies out.

But after the utility model has increased belleville spring, belleville spring can also carry out second-compressed, swelling watt can increase extra tension force again, for example increase mentioned above the tension force of 400kgf, and this swelling watt total can increase again the friction force of 120kgf.And the technical scheme in employing the present embodiment, raising tension force that can be larger, and then improve the unwinding and rewinding machine of employing swelling watt form to the control ability of material volume velocity variations, the acceleration/accel that needs are larger in the time of can adapting to speed governing and/or material are rolled up the larger occasion of rotor inertia, have expanded the range of use of such machine.

Three) after the swelling operation is finished; outer baffle is contained in the swelling watt; utilize two abutment sleeves and two pilot bars to realize location to outer baffle; wherein two abutment sleeves have been finished point location jointly; long abutment sleeve has also been finished and has been prevented the location that swings; then use nut locking, can play the protective effect to the outer side edges of steel coil strip.

After finishing the location, the outside of steel coil strip, can begin the passive band of putting.

Dish spring group in the present embodiment also can be replaced by the elasticity of compression parts of other type, other compressibi1ity springs of mentioning in can the 11st piece of spring chapter 1 spring of Chemical Industry Press's version " mechanical design handbook " in 2002 the 3rd volume referring to Cheng Daxian chief editor, resilient sleeve for example, cylindroid helical-coil compression spring etc.Nut 16 can be replaced by the limiting stopper of pin joint or the locating dowel pin by the pull bar axis.

Embodiment 3:

The first structure: see also Fig. 1 and Figure 11 a, the afterbody of each start cylinder all is hinged on the riser of casing, and the cylinder bar is connected with the inner of pull bar 17 by a lever 35.The inner of pull bar 17 is connected with the first Y-shaped connector 34, start cylinder cylinder club head is equipped with the second Y-shaped connector 36, the two ends of lever 35 are hinged with the first Y-shaped connector 34 and the second Y-shaped connector 36 respectively, wherein be the elongated slot non-circular hole with the hinged part of the first Y-shaped connector, the middle part of lever 35 is connected with casing riser and the 17 homonymy settings of driven pull bar of bearing 63 with to be fixed in casing riser upper bracket 63 hinged.

The second structure: see also Figure 11 b, form the second structure that two start cylinders 33 of one group are connected with pull bar: be with the difference of above-mentioned the first structure, the afterbody of start cylinder 33 is directly installed on the riser of casing, lever 35 is used for should be elongated slot with the hinged junction, end of the first Y-shaped connector 34 and the second Y-shaped connector 36 and non-circular hole will cause lever to rotate otherwise the connection between the three is the structure of " bearing pin+circular hole ".

Below 2 kinds of leverages different from above two kinds of leverages be to have changed the connection mode of start cylinder and pull bar.Realize the contraction of pull bar in embodiment 1 by stretching of start cylinder cylinder bar, in the present embodiment, contraction by start cylinder cylinder bar realizes the contraction of pull bar.

The 3rd kind of structure: see also Figure 12 a, be with the difference of the first structure among the embodiment 1: the middle part of lever 35 and the second Y-shaped connector 36 are hinged, one end of lever 35 and the first Y-shaped connector 34 are hinged, wherein be the elongated slot non-circular hole with the hinged part of the first Y-shaped connector, the other end of lever 35 is hinged with the bearing 63 that is fixed on the casing riser, and bearing 63 and start cylinder were located at the both sides of pull bar 17 in 33 minutes.When the start cylinder stretched out, pull bar is side shifting outside casing, and a swelling watt radius is reduced; When the start cylinder shrank, pull bar moved to box house, made swelling watt spreading to setting diameter.

Embodiment 4:

Be the registration device of outer baffle with the difference of embodiment 1.See also Figure 13 a and Figure 13 b, in the present embodiment, the registration device of outer baffle comprises and is sleeved on the outer locking of swelling watt watts 53, be connected with the holding screw and the radius stay 54 that are pressed in the swelling watt in the locking watts 53, radius stay passes 55 slips of outer baffle inner ring and is installed in the spoke 56, radially be provided with slotted hole 561 on the spoke, be provided with the lock screw affixed with radius stay in the slotted hole.Locking watt compresses swelling by the holding screw on it and watt realizes locking, and radius stay compresses spoke by the lock screw on it and realizes the location.

Above-mentioned outer baffle registration device can be avoided the large problem of embodiment 1 outer baffle registration device difficulty of processing.Because, in embodiment 1, outer baffle and turnbarrel are except the nested relationship of abutment sleeve and pilot bar, two incoherent parts fully, and overcoat has the outer baffle pilot bar of abutment sleeve still to be welded on the turnbarrel by riser, through this hot working of welding, total just more likely produces new error because expand with heat and contract with cold, reduce the quality of fit of abutment sleeve and outer baffle pilot bar, increasing tolerance clearance needs to guarantee to install, thus, improved the fugitiveness of outer baffle location; The raising working accuracy increases tooling cost.The two scheme has certain drawback.

Outer baffle registration device among the embodiment 1, owing to being provided with the outer baffle pilot bar in the end of riser, pilot bar is in a single day stressed, for riser, it is a cantilever beam structure of only having fixed at afterbody, and outer baffle pilot bar itself also is a cantilever beam structure of only having fixed at afterbody, and this structure is very unfavorable for carrying.In order to reduce the negative effect of riser cantilever beam structure, can reduce the height of riser, if but reduce height, just need to increase the length of radius stay in the outer baffle registration device, and radius stay itself also is a cantilever beam structure, if increase the length of radius stay, certainly will reduce its rigidity and load-carrying capacity again.And outer baffle is after being put into the material volume on the initiative rolling-unrolling machine, be manually installed on the initiative rolling-unrolling machine, in order to reduce workman's work load, what need again as much as possible outer baffle to be done is lighter, so its material is also selected the material that density is less, intensity is relatively poor or wall thickness is thinner, so that its rigidity is not easy to do again is too much.The two has just consisted of contradiction.

The present embodiment, change the registration device of outer baffle into the locking that directly is sleeved in the swelling watt watt, locking watt shape and size and swelling watt coupling, no matter how a swelling watt formed circular outer diameter size changes, the shape of swelling watt itself is fixed, so locking watt can watt realize stable cooperating with swelling.And the variation of swelling watt external diameter is to remedy by adjusting the position of radius stay in spoke during swelling.The present embodiment compresses the location that swelling watt realizes locking watt by holding screw, and is simple in structure, easy to operate.

In the present embodiment, the steel band outer baffle adopts plectane to add the structure that spoke adds inner ring, and the effect of spoke is equivalent to gusset.The steel band outer baffle also can adopt the structure of outer ring+spoke among the embodiment 1+inner ring.

Embodiment 5:

See also Fig. 8, and the difference of embodiment 1 is: between first shaft shoulder of dish spring support ring 19 and pull bar, clamp and adjust packing ring 60, adjust packing ring 60 and be sleeved on the pull bar 17.Dish spring support ring 19 does not directly contact with first shaft shoulder 171 of pull bar, but contact with the adjustment packing ring 60 that is used for size adjusting, the internal diameter of adjusting packing ring 60 is identical with the external diameter of pull bar 17, the external diameter of adjusting packing ring 60 is identical with the internal diameter of the first inner ring sleeve 21, and can endwisely slip between the first inner ring sleeve 21.

In process of production, the internal diameter of steel band material volume can not be completely unified, and the utility model depends on the locking start cylinder of pulling pull bar and can move fully and put in place, utilizes lock in the start cylinder to guarantee not occur the material volume accident that flies out.But the position of material volume internal diameter and pull bar pulling is to have certain relation of interdependence, if the internal diameter of material volume is larger than theoretical value, after putting in place, the start cylinder cylinder bar that causes driving pull bar still can't increase to the position, also can't guarantee even again discharge amount of compression by belleville spring, so just need to adjust the relative position of dish spring support ring and pull bar.For example, the position of dish spring support ring is outwards mobile, and then needing increases thickness or the quantity of adjusting packing ring, so that the start cylinder is when moving to terminal, the external diameter of swelling watt is less than original steel coil strip internal diameter; Vice versa.Adjust packing ring various ways can be arranged: 1) for certain material volume internal diameter size, calculate the every increase certain size of internal diameter (for example 1mm or 0.5mm), the thickness of needed adjustment packing ring, each adjusts the internal diameter of corresponding a kind of material volume of thickness of packing ring, when the internal diameter of steel coil strip changes to some extent, increase or reduce corresponding adjustment packing ring number; The size of required size adjusting packing ring when 2) calculating respectively discharging volume internal diameter and be different size is made respectively the adjustment packing ring of coil diameter in corresponding each steel band, when the internal diameter of steel coil strip changes to some extent, and integral replacing size adjusting packing ring.

Embodiment 6:

Among the embodiment 1, swelling watts 7 is connected with the swelling connecting rod by swelling watt inner reinforced plate 8 and is connected with the outdoor gusset 12 of plain bearing, swelling connecting rod one end and the outdoor gusset of plain bearing plane are hinged, the other end and swelling watt inner reinforced plate plane is hinged, and the outdoor gusset of plain bearing and plain bearing chamber are connected, and swelling watt inner reinforced plate and swelling watt are connected.Under the constraint that does not have other, in the swelling plane of movement of swelling watt, the swelling connecting rod can carry out with respect to the plain bearing chamber swing of single degree of freedom, and swelling watt can be carried out the swing in the plane centered by the hole of swelling interlinking lever end.So take the plain bearing chamber as system of axes, swelling watt has two degree of freedom.So can claim to be connected for 2DOF between swelling watt and the plain bearing chamber.

In like manner, among the embodiment 1, a transverse plane of an end of two groups of support link 9 and swelling watt inner reinforced plate 8 is hinged, and outer gusset 11 planes of the other end and turnbarrel are hinged.Because two groups of support link are isometric, and two hinged holes of swelling watt inner reinforced plate and two groups of support link are and turnbarrel outward gusset and two groups of two holes that support link is hinged, and pitch-row is the same, and this has just consisted of parallel-crank mechanism.And the swelling watt mode with parallel-crank mechanism connects and turnbarrel, so swelling watt can only be in parallel with turnbarrel all the time mode, under support link and swelling connecting rod drive, carry out parallel, and any rotation or swing does not occur for self.Its position only is decided by the angle between the outer gusset of support link and turnbarrel, so be connected for single degree of freedom between swelling watt and the turnbarrel.

So for 2DOF is connected, and be that 1 degree of freedom is connected between the turnbarrel between swelling watt and the plain bearing chamber, so connecting, the M degree of freedom described in the utility model content is connected with the N degree of freedom, M+N=3 is this concept.

Except embodiment 1 described swelling watt bracing or strutting arrangement, can also adopt following method for supporting:

The first mechanism:

As shown in figure 14, this figure is for simplifying view, swelling connecting rod and support link are reduced to straight line, every place hinge hole is reduced to circle, and among the figure, the plain bearing chamber watt links to each other by two groups of isometric swelling connecting rods and swelling, and two hinged holes of swelling watt inner reinforced plate and two groups of support link are and the outdoor gusset of plain bearing and two groups of two holes that support link is hinged, pitch-row is the same, consists of parallel-crank mechanism, so swelling watt is that single degree of freedom is connected with the plain bearing chamber.And swelling watt is by one group of support link and the outer link of boards of turnbarrel, and swelling watt is that 2DOF is connected with turnbarrel.In the breathing plane of movement of every tensioner watt, a described swelling watt mode that connects with the M degree of freedom is connected with the plain bearing chamber, is connected with turnbarrel in the mode of N degree of freedom connection, and M is that 1, N is 2, and M+N=3.

In this structure, although the weight of material volume is by tensioner connecting rod and support link shared, be that some radial weight is born by the plain bearing chamber, but shown in Fig. 1, Fig. 6 a and Fig. 6 b, the plain bearing chamber is when sliding into maximum distance, still some length is embedded in the turnbarrel, and diametral load is born by turnbarrel, does not have the problem of utilizing two-direction thrust bearing to bear radial weight.

The second mechanism:
