Iigiya zeentshulube zizinto zothumelo lwamandla ezisetyenziswa ikakhulu njengonciphiso olukwinqanaba eliphezulu lokutshintsha ikhondo lokujikeleza kweshaft kunye nokunciphisa isantya kunye nokunyusa i-torque phakathi kweshafti ezijikelezayo ezingahambelaniyo. Zisetyenziselwa kwi-shafts ene-non-intersecting, i-perpendicular axes. Ngenxa yokuba amazinyo eegiya ze-meshing etyibilika edlula enye kwenye, iigiya zeentshulube azisebenzi kakuhle xa zithelekiswa nezinye iigiya zokuqhuba, kodwa zinokuvelisa ukuncipha okukhulu kwesantya kwiindawo ezixinene kakhulu kwaye ke zinezicelo ezininzi zemizi-mveliso. Ngokusisiseko, iigiya zeentshulube zinokuhlelwa njenge-enveloping enye kunye ne-double-enveloping, echaza ijometri yamazinyo ane-meshed. Iigiya zeentshulube zichazwe apha kunye nengxoxo yokusebenza kwazo kunye nezicelo eziqhelekileyo.
Iigiya zeentshulube eziyicylindrical
Eyona ndlela isisiseko yombungu yirekhi ye-involute eveliswa ngayo izixhobo ze-spur. Amazinyo erakhi aneendonga ezithe tye kodwa xa esetyenziselwa ukwenza amazinyo kwindawo engenanto avelisa uhlobo lwamazinyo olugobileyo lwesixhobo se-involute spur. Eli zinyo lentshulube lihamba lijikeleza umzimba wombungu. Ukukhwelana ivili lombungu yenziwe ngeizixhobo ze-helicalamazinyo asikwe nge-engile ehambelana ne-engile yezinyo leentshulube. Ukumila kwe-spur yenyani kwenzeka kuphela kwindawo esembindini wevili, njengoko amazinyo egoba ukugquma umbungu. Isenzo se-meshing sifana neso se-rack eqhuba i-pinion, ngaphandle kokuba intshukumo yokuguqulela ye-rack ithathelwa indawo yi-rotary motion ye-worm. Ukugoso kwamazinyo evili maxa wambi kuchazwa “njengomqala.”
Iintshulube ziya kuba nomsonto omnye ukuya kutsho kwezine (okanye ngaphezulu), okanye isiqalo. Umsonto ngamnye ufaka izinyo kwivili leentshulube, elinamazinyo amaninzi nedayamitha enkulu kunombungu. Iintshulube zinokujikela kulo naliphi na icala. Amavili eentshulube akholisa ukuba namazinyo angama-24 ubuncinci kwaye isixa semisonto yeentshulube kunye namazinyo angamavili kufuneka ngokuqhelekileyo sibe ngaphezulu kwama-40.
Uninzi lwezixhobo zokunciphisa i-worm-gear ngokwethiyori ziyazitshixa, oko kukuthi, azikwazi ukuqhutywa livili leentshulube, iadvanteji kwiimeko ezininzi ezifana nokunyuswa. Apho ukuqhuba umva kuluphawu olunqwenelekayo, ijometri yombungu kunye nevili inokuhlengahlengiswa ukuyivumela (ehlala ifuna uqalo oluninzi).
Umlinganiselo wesantya sombungu kunye nevili umiselwa ngumlinganiselo wenani lamazinyo evili ukuya kwimisonto yeentshulube (hayi iidiameters).
Ngenxa yokuba umbungu ubona ngokuthelekisa ukuguga okungaphezulu kunevili, amaxesha amaninzi kusetyenziswa izinto ezingafaniyo kumntu ngamnye, njengombungu oqinileyo oqhuba ivili lobhedu. Amavili ePlastiki entshulube ayafumaneka.
Iigiya zeentshulube ezisigqumayo esinye kunye neKabini
I-enveloping ibhekiselele kwindlela amazinyo evili leentshulube asonga ngalo inxalenye yevili. Oku kunika indawo enkulu yoqhagamshelwano. Isixhobo seentshulube esigqumayo esinye sisebenzisa intshulube eyicylindrical ukuhlanganisa amazinyo asemqaleni wevili.
Ukunika indawo enkulu yokudibana kwamazinyo, ngamanye amaxesha intshulube ngokwayo iyahlatywa--emile okwe hourglass--ukuhambelana nokugoba kwevili leentshulube. Olu cwangciso lufuna ukubekwa kwe-axial ngononophelo. Iigiya zeentshulube ezigquma kabini zintsonkothile kumatshini kwaye zibona usetyenziso olumbalwa kuneegiya zeentshulube ezigquma enye. Inkqubela phambili kwi-machining yenze uyilo olugubungela kabini lusebenziseka ngakumbi kunokuba lwalunjalo ngaphambili.
Iigiya ze-helical ezinqamlezileyo ngamanye amaxesha zibizwa ngokuba ziigiya zeentshulube ezingagqubutheleyo. Isibambiso senqwelomoya kusenokwenzeka ukuba ibe luyilo olungagqubutheleyo.
Usetyenziso
Isicelo esiqhelekileyo sokunciphisa i-worm-gear yi-belt-conveyor drives njengoko ibhanti lihamba ngokucotha ngokucothayo ngokubhekiselele kwi-motor, okwenza imeko yokunciphisa umlinganiselo ophezulu. Ukuxhathisa ekuqhubeni ngasemva kwivili leentshulube kungasetyenziselwa ukunqanda ukuguqulwa kwebhanti xa umhambisi eyeka. Olunye usetyenziso oluxhaphakileyo lukwii-actuator zevalvu, iijekhi, neesarha ezijikelezayo. Ngamanye amaxesha zisetyenziselwa ukwenza isalathisi okanye njengezinto ezichanekileyo zokuqhuba iiteleskopu kunye nezinye izixhobo.
Ubushushu yinkxalabo ngegiya zeentshulube njengoko intshukumo iyinto etyibilikayo njenge nut kwisikrufu. Kwisixhobo sokuvuselela ivalvu, umjikelo womsebenzi unokwenzeka ukuba ube ngamanye amaxesha kwaye ubushushu bungaphela ngokukhawuleza phakathi kokwenziwa rhoqo. Kwi-conveyor drive, kunye nokusebenza ngokuqhubekayo, ubushushu budlala indima enkulu kwizibalo zoyilo. Kwakhona, izithambiso ezikhethekileyo ziyacetyiswa kwiinkqubo zokuqhuba iintshulube ngenxa yoxinzelelo oluphezulu phakathi kwamazinyo kwakunye nokuba nokwenzeka kwenyongo phakathi kweentshulube ezingafaniyo kunye nemathiriyeli yevili. Izindlu zokuqhuba iintshulube zihlala zifakelwe amaphiko okupholisa ukuphelisa ubushushu obusuka kwioyile. Phantse nasiphi na isixa sokupholisa sinokufezekiswa ukuze izinto ezishushu zezixhobo zeentshulube ziqwalaselwe kodwa hayi umda. Iioyile ziyacetyiswa ngokubanzi ukuba zihlale ngaphantsi kwe-200 ° F ukuze kubekho ukusebenza okusebenzayo kwayo nayiphi na i-worm drive.
Ukuqhuba umva kunokuthi kwenzeke okanye kungenzeki njengoko kuxhomekeke kungekuphela nje kwii-engile ze-helix kodwa nakweminye imiba engaphantsi kokulinganisa okufana nokukhuhlana kunye nokungcangcazela. Ukuqinisekisa ukuba iya kuhlala isenzeka okanye ayisoze yenzeke, umyili we-worm-drive kufuneka akhethe ii-engile ze-helix ezinokuthi ziphakame ngokwaneleyo okanye zibe nzulu ngokwaneleyo ukuze zigqithise ezinye izinto eziguquguqukayo. Uyilo olulumkileyo luhlala lucebisa ukudityaniswa kwebraking engafunekiyo kunye nezitshixo zokuzitshixa apho ukhuseleko lusemngciphekweni.
Izixhobo zeentshulube ziyafumaneka njengeeyunithi ezihlala endlwini nanjengezixhobo zezixhobo. Ezinye iiyunithi zinokuthengwa ngee-servomotors ezidityanisiweyo okanye njengoyilo olunesantya esiphezulu.
Iintshulube ezichanekileyo ezichanekileyo kunye neenguqulelo zero-backlash ziyafumaneka kwizicelo ezibandakanya ukucuthwa kokuchaneka okuphezulu. Iinguqulelo zesantya esiphezulu ziyafumaneka kwabanye abavelisi.
