Spiral Electric Resistor Nicr Alloy 1 - 5 Mohm Don Abubuwan Haɗaɗɗen Na'urar Kwandishan
1.Material General Description
Constantanshi ne na jan karfe-nickel gami kuma aka sani daEureka,Gaba, kumaJirgin ruwa. Yawanci ya ƙunshi 55% jan karfe da 45% nickel. Babban fasalinsa shine tsayayyarsa, wanda ke dawwama akan yanayin zafi da yawa. An san sauran alluna masu ƙarancin zafin jiki iri ɗaya, kamar manganin (Cu86Mn12Ni2).
Don auna manyan ƙwayoyi, 5% (50 000 microstrian) ko sama, Ananed Constantan (P Alloy) shine kayan Gridy. Constantan a cikin wannan tsari yana da yawaductile; kuma, a cikin tsayin ma'auni na inci 0.125 (3.2 mm) kuma ya fi tsayi, ana iya takurawa zuwa>20%. Ya kamata a ɗauka a zuciya, duk da haka, cewa a ƙarƙashin manyan nau'ikan cyclic P alloy zai nuna wasu canje-canje na dindindin na juriya tare da kowane sake zagayowar, kuma ya haifar da daidaitaccen tsari.sifilicanzawa a cikin ma'aunin nauyi. Saboda wannan siffa, da kuma halin gazawar grid da wuri-wuri tare da maimaita iri, P alloy ba a saba da shawarar don aikace-aikacen nau'in cyclic ba. Ana samun P alloy tare da lambobin STC na 08 da 40 don amfani akan karafa da robobi, bi da bi.
2. Gabatarwar bazara da aikace-aikace
Karkace torsion spring, ko gashin gashi, a cikin agogon ƙararrawa.
A volut spring. Ƙarƙashin matsewar coils suna zamewa a kan juna, don haka ba da damar tafiya mai tsawo.
Maɓuɓɓugan ruwa na tsaye na tankin Stuart
Tashin hankali ya taso a cikin na'urar sake maimaita layi mai ninke.
Tsutson sandar murɗaɗɗen kaya
Ganyen bazara a kan babbar mota
Ana iya rarraba maɓuɓɓugar ruwa dangane da yadda ake amfani da ƙarfin lodi a kansu:
Tsuntsu / tsawaita bazara - an tsara bazara don yin aiki tare da nauyin tashin hankali, don haka bazara yana shimfiɗa yayin da aka yi amfani da shi.
Matsi mai raɗaɗi - an tsara shi don yin aiki tare da nauyin matsawa, don haka bazara ya fi guntu yayin da aka yi amfani da shi.
Torsion Spring - ba kamar nau'ikan da ke sama ba wanda nauyin nauyi ya zama ƙarfin axial, nauyin da aka yi amfani da shi a kan torsion spring yana da karfin juyi ko karkatarwa, kuma ƙarshen bazara yana juyawa ta hanyar kusurwa yayin da ake amfani da kaya.
Tsawon bazara - kayan tallafi mai goyan baya ya kasance iri ɗaya a duk tsawon lokacin juyawa.
Sauyawan bazara - juriya na nada don ɗauka ya bambanta yayin matsawa.
Maɓallin ƙunci mai canzawa - juriya na nada don ɗaukar nauyi na iya bambanta da gaske misali ta tsarin sarrafawa, wasu nau'ikan waɗannan maɓuɓɓugan ruwa kuma suna bambanta tsawonsu ta haka suna ba da damar kunnawa.
Hakanan ana iya rarraba su bisa ga siffar su:
Flat spring - irin wannan nau'in an yi shi da karfe mai laushi.
Injin bazara - ana kera irin wannan nau'in bazara ta hanyar sarrafa kayan masarufi tare da aikin lathe da/ko niƙa maimakon aikin murɗawa. Tun lokacin da aka kera shi, bazarar na iya haɗawa da fasali ban da nau'in roba. Machined marẽmari za a iya yi a cikin hankula load lokuta na matsawa / tsawo, torsion, da dai sauransu.
Macijin Serpentine – zig-zag na waya mai kauri – galibi ana amfani da shi a cikin kayan ɗaki na zamani.
