外文文献Belt conveyor is a machinery for conveying goods without end conveyer belt moving continuously . It has simple structure , low cost , long transportation distance and high productivity . With the development of modern industrial science and technology , belt conveyor has become more and more important in industrial production . With the development of belt joint technology, belt conveyor has developed to a high level. In the 17th century, the prototype of modern bucket hoists and scraper conveyors began to use aerial ropeway to transport loose materials. In the middle of 19th century, conveyors of various modern structures appeared one after another. In 1868, Belt conveyor appeared in England, screw conveyor in America in 1887, steel belt conveyor in Switzerland in 1905, inertial conveyor in England and Germany in 1906. After that, the conveyor receives The impact of technological progress in the mechanical manufacturing, electrical machinery, chemical and metallurgical industries has been continuously improved, gradually from the completion of the internal transportation of the workshop to the completion of material handling within the enterprise, between enterprises and even between cities, Become an indispensable part of material handling system mechanization and automation.1.Beltconveyorhavingacirculatingconveyingbelt,comprising:carryingrollersarrangedbetweenatopstrandandabottomstrandofthecirculatingconveyingbelt;upperandlowerguiderollersactingonupperandlowerbeadsonthecirculatingconveyingbeltandforcingthecirculatingconveyingbeltradiallyoutward,theupperandlowerbeadsbeingformedoppositetoeachotheronthecirculatingconveyingbelt;atleastonetoothedringinteractingwithatleastonetoothedbeltarrangedonthecirculatingconveyingbelt,wherebytheupperbeadisneighboredtothetoothedbelt;andadrivedeviceformovingthecirculatingconveyingbelt.2.Beltconveyoraccordingtoclaim1,whereinthetoothedbeltisarrangedontheundersideofthecirculatingconveyingbelt,intherunningdirectionofthecirculatingconveyingbelt.3.Beltconveyoraccordingtoclaim2,whereinthetoothedringisarrangedattheendofthecarryingrollers,andwhereinprojectingfromtheendofafirstcarryingrollerisajournalfortheconnectionofthedrivedevice.4.Beltconveyoraccordingtoclaim3,whereinthetoothedbeltextendsintheregionofthesideborderofthecirculatingconveyingbelt.5.Beltconveyoraccordingtoclaim1,whereinthetoothedbeltandthetoothedringhavemultisplining.6.Beltconveyoraccordingtoclaim1,whereinKevlarfilamentsareincorporatedinthetoothedbelt.7.Beltconveyoraccordingtoclaim1,whereinthetoothedbeltisattachedonthecirculatingconveyingbeltviaoneofwelding,vulcanizing,andadhesivelybondingthereto.8.Beltconveyorhavingacirculatingconveyingbelt,comprising:carryingrollersarrangedbetweenatopstrandandabottomstrandofthecirculatingconveyingbelt;andadrivedeviceandaforce-transmissiondeviceformovingtheconveyingbelt,whereinapairofelementswhichinteractwithoneanotherwithaformfitisprovidedforforce-transmissionpurposes,oneofsaidelementsbeingassignedtotheforce-transmissiondeviceandtheotherofsaidelementsbeingassignedtotheconveyingbelt,whereintheforce-transmissiondevicecomprisesatleastonetoothedring,andwhereinthecirculatingconveyingbelthasatleastonetoothedbelt,thetoothedringandtoothedbeltinteractingwithaformfit,whereinthetoothedbeltisaconstituentpartofatoothed-beltcomponentwhichisofessentiallyU-shapeddesigninthetransversedirectionofthetoothedbeltandengagesaroundtheside-borderregionoftheconveyingbelt.9.Beltconveyoraccordingtoclaim8,whereinthetoothedringisassignedatleasttoafirstbelt-conveyorcarryingroller,whichisoperativelyconnectedtothedrivedevice.10.Beltconveyoraccordingtoclaim8,furthercomprisingacounterpressuredevice,whichactsonthatregionofthetoothed-beltcomponentwhichextendsonthetopsideofthecirculatingconveyingbelt.11.Beltconveyoraccordingtoclaim8,whereinthefreeendsoftheessentiallyU-shapedtoothed-beltcomponentaredesignedasabead.12.Beltconveyoraccordingtoclaim8,furthercomprisingguiderollers,whichactononeofthetoothedbeltandthetoothed-beltcomponent.13.Beltconveyorhavingacirculatingconveyingbelt,comprising:carryingrollersarrangedbetweenatopstrandandabottomstrandofthecirculatingconveyingbelt;upperandlowerguiderollersactingonupperandlowerbeadsonthecirculatingconveyingbeltandforcingthecirculatingconveyingbeltradiallyoutward,theupperandlowerbeadsbeingformedoppositetoeachotheronthecirculatingconveyingbelt;atleastonetoothedringinteractingwithatleastonetoothedbeltformedonthecirculatingconveyingbelt,wherebytheupperbeadisneighboredtothetoothedbelt;andadrivedeviceformovingthecirculatingconveyingbelt,whereinapairofsaidguiderollersarearrangedonangledretainingarmssuchthattheguiderollersactononeofthetoothedbeltandtheupperandlowerbeads,bywayofinclinedrunningsurfaces.14.Beltconveyoraccordingtoclaim12,whereinineachcaseonepairofguiderollersonthetopstrandandonthebottomstrandofthecirculatingconveyingbeltactononeofthetoothedbeltandthetoothed-beltcomponent,extendingovertheentireborderregionofthecirculatingconveyingbelt.15.Beltconveyoraccordingtoclaim1,whereinthecarryingrollersareofconicalconfigurationandformabeltcurve,andwhereinthetoothedringundergoesaform-fittingconnectioninrelationtothecirculatingconveyingbeltatthelarger-diameterendoftherespectivecarryingrollerontheouterradiusofthebeltcurve.16.Thebeltdrivingdeviceofclaim1,whereinoneofsaidtoothedringandsaidtoothedbeltisreleasablyfixedtothecarryingrollers.Beltconveyoraccordingtoclaim16,whereinoneofsaidtoothedringandsaidtoothedbeltisreleasablyfixedtotheforce-transmissiondevicebyoneof.Thepresentinventionrelatestoabeltconveyorhavingacirculatingconveyingbelt,havingcarryingrollers,whicharearrangedbetweenthetopstrandandthebottomstrandoftheconveyingbelt,andhavingadrivedeviceandaforce-transmissiondeviceformovingtheconveyingbelt.BACKGROUNDOFTHEINVENTIONItisknownfrompracticeforforcetobetransmittedfromthedrivedevicetotheconveyingbeltofabeltconveyorviafrictionfitting.Thefrictionbetweenadrivencarryingrollerandtheconveyingbelt,forexample,mayevenbesufficientforthispurpose.Therestofthecarryingrollersaremountedinamovablemannerandrotatealong.
