Figure 6 shows that the coil of star-shaped support 3, an endless belt holding device 6a to 6d is arranged on each supporting arm with four supporting arms.Each supporting arm all has two endless belt 2 in the coil inboard.Also represented simultaneously the giving year device between two supporting arms, this gives a year device and has the holding device of radially excellent bar 30 as two endless belt 2.Can also carry one or more this giving device and be installed in every section coil between this supporting arm in addition.Like this, can make the coil that is suitable under the high load according to improved method under the low-cost situation.
Fig. 7 is one section lattice coil, has two kinds of different giving to carry device, with the holding device of radially excellent bar 30 as endless belt 2.
Fig. 8 is a profile, shows with radially excellent bar 30 and compresses the situation that this is connected attachment strap with two dresses endless belt thereon.Connecting attachment strap 32 is pressed on space bar 31 and the insulation intermediate plate 16.There is insulation board 33 to cover on it on this connection attachment strap 32.There is excellent bar 30 to push down more again.The connection attachment strap part of stretching to the coil the inside can be connected with an end of winding.
Fig. 9 represents the end-view according to the fastening place of connection attachment strap among Fig. 8.Endless belt 2 does not contact with opening and can clamp by opening 34.For the description operation mode, can consider Fig. 1 and Fig. 2 in the lump.Endless belt 2 axially has elasticity, utilizes this elasticity that coil is born and give to add load.Endless belt 2 can be undertaken special by various uses.The manufacture method of this endless belt 2 is: twine many layers with the insulating tape that floods with hardening synthetic resin on anchor clamps, and make its hardened forming.Therefore this endless belt 2 can manufacture the very little product of tolerance.
Be that example is introduced so that a pair of endless belt is installed between endless belt holding device 6a and the 6a ' now.The endless belt holding device 6a ' of bottom installs, and two endless belt 2 are installed on the endless belt support 7 of bottom, connects so that form reliably.When the endless belt holding device 6a on top is installed, too endless belt 2 is installed on the endless belt support 7, connect so that form reliably.After the right half cycle that installs this endless belt holding device 6a, just spacer block 13 is tucked on the plane 11 of bolt 10.Assembly key 14 is inserted in space when beginning between the base of spacer block 13 and slotted hole 5 inadequately.The working pressure machine assembles.Promptly at one end supporting and passing through arm 4 and intermediate plate 16 and act on the end face of winding, acting at the other end on the contact-making surface 12 of support 7.This forcing press is just pressed to endless belt support 7 top, and endless belt 2 is subjected to giving first pressure, just stretches out towards axial direction.This power of giving load is larger than needed numerical value.Can insert assembly key 14 now, pad 17 in the middle of can packing in the time of if necessary.When removed the outside give carry active force after, this assembly key 14 is just clamped, endless belt 2 can keep giving of necessary requirement to carry numerical value and shearing force load phenomenon does not take place.Having only in this case could be with endless belt holding device 6a, firm in addition fastening of the bolt 10 on the 6a '.
To give carrying putting on the coil, generally all be that segmentation is carried out on coil.Because can only apply the less power of carrying of giving.In addition, coil grading applies to give carrying and can make endless belt holding device 6a ... 6d and 6a ' ... 6d ' can enter its installation site better.
On endless belt support 7, half garden shape contact-making surface of endless belt 2 can guarantee that endless belt 2 bears drag load uniformly and do not have the shearing generation.Each endless belt 2 can bear gives the power of carrying, and increases along with the increase of the number of plies of the glass fiber reinforcement insulating tape that is twined, and also can the ability to bear of giving the power of carrying be strengthened the number increase of the endless belt 2 installed.As shown in Figure 1, also endless belt 2 can be placed on each different position, to adapt to each concrete load condition, for low load, as long as it is just passable at endless belt holding device 6b and between 6b ' installation endless belt 2, rather than usually with coil holding device 6a, 6a ' and 6b, 6b ' all loads onto.Equally, when being used for low load condition, also can save outside endless belt holding device 6d and 6d ' for the another kind of zonary structure on the right in Fig. 1.Many possible deformed configurations all can guarantee to provide with good and the most economic giving carries device.
Endless belt holding device shown in Figure 3 is the form of slightly simplifying of endless belt holding device shown in Figure 2.This device is applicable to low weight giving on year coil, because the assembly key 14 that plastics are done bears shearing.So can only bear less load.Fig. 4 represents a kind of economic especially coil that device is carried in single giving that has, during assembling, the bottom holding device is installed earlier, then each endless belt 2 is installed on the excellent bar 30, connect so that form reliably, intermediate plate 16 is inserted between the surface of excellent bar 30 and winding one end.Endless belt 2 is pushed on the excellent bar 30 on top then, connected so that form reliably.Moreover, apply when giving load, the working pressure machine, an end bearing of this forcing press is an end surfaces place above winding, and the other end is bearing on the excellent bar 30, and excellent bar 30 is pressed to the top.The selected power of carrying of giving, than the numerical value that requires more greatly.Intermediate plate 16 and space bar 31 are located to load onto in interval (space) between excellent bar 30 and winding one end surfaces.This assembling is carried out in this case, promptly removed forcing press from the outside is added give load after, desired just the giving of the load that each endless belt 2 bears is carried numerical value, and does not bear any shearing.This also provides possible best fit when adopting the structure of various endless belt 2 in the multilayer winding.
Various shown in Fig. 5,6,7 give carries a device form and can mutually combine or combine with other form, its may in conjunction with the installation method need not to illustrate one by one.With the endless belt that gives moulding with connector particularly will give load device holding device, be secured to principle on the coil with the endless belt that gives moulding, also can be applied in other fastening, for example: be used for the carrying aperture or connecting attachment strap 32 is fixed in coil, make this aperture connect attachment strap and can bear bigger torsion.
About the visible Fig. 8 of the examples of implementation that are used for fastening this connection attachment strap 32 and Fig. 9.During assembling, with intermediate plate 16, space bar 31, connect attachment strap 32 and insulation board 33 and be deposited in together as far as possible,, two endless belt 2 are shifted onto on the excellent bar 30 so that it is contained on the winding end face, connect so that form reliably, these two endless belt pass through opening 34, and do not collide with it.End over there installs to two endless belt 2 on the other excellent bar 30, and bears and give load and be not subjected to shearing, and as mentioned previously, connect attachment strap 32 and just tightly clamped this moment.
Also the intermediate plate 16 that is positioned at coil sides can be designed to pectination, like this can separating when coil bears heavy load with end coil safety.
Whole giving carried device, in general is to make with nonmagnetic substance; Can manufacture with plastics full during for special purpose, under these circumstances, bear the position of big load and must strengthen with glass fibre.
According to the present invention, the embodiment of above-mentioned coil method for production is described as follows: coil Volume coiled is given fixed style; Temporarily tie then,, make this casting resin sclerosis subsequently with the casting resin dipping with belt.After the hardening of resin, install to give to coil again and carry device.When this process, endless belt 2 is pushed to give on the loaded securement device, connect so that form reliably.Utilize forcing press that this endless belt 2 is born to be a bit larger tham the power of carrying of giving of requirement numerical value, an end bearing of forcing press is on the end face of coil and pressurization, and the other end is bearing on the holding device, makes endless belt 2 add load axially giving.Pad 17 in the middle of assembly key 14 and the compensation that trims is placed in the holding device, and like this, when forcing press being applied to giving after the power of carrying removes on the endless belt from the outside, this endless belt just can bear and desiredly give year numerical value.Last fastening this annular retaining device, and spread the belt of being tied temporarily.
If each single fixture is given separately when adding load earlier, then giving of endless belt 2 adds load and preferably operates with less and light forcing press, and coil gives with this method segmentation and adds load.It is exactly to guarantee coil holding device 6a all the time that this method also has a benefit ... 6d has good operating characteristics, and this just can make assembly key 14 install easily.
Final give that to add load be 0.5% of endless belt 2 loaded lengths at least, under the situation that great majority are used, be no more than 1.2%.
