MAGNABEND NHOROONDO YEKUDZIDZWA NEKUGADZIRA
Genesisi yeChirevo:
Kare muna 1974 ndaifanira kugadzira mabhokisi ezvirongwa zvemagetsi edzimba.Kuti ndiite izvi ndakazvigadzirira dhairekitori rakashata kwazvo kubva muzvidimbu zvemakona emakona akasungirirwa pamwechete uye akabatwa mune vice.Kuti nditaure zvishoma zvaive zvakaoma kushandisa uye kwete zvakanyanya.Nenguva isipi ndakafunga kuti yakanga yava nguva yokuita chimwe chinhu chiri nani.
Saka ndakatanga kufunga nezve kugadzira folda 'yakakodzera'.Chinhu chimwe chaindinetsa ndechekuti iyo clamping chimiro chaifanira kusungirirwa kumashure kwemuchina kungave kumagumo kana kumashure uye izvi zvaizokanganisa zvimwe zvezvinhu zvandaida kugadzira.Saka ndakasvetuka nekutenda ndokuti ...Zvakanaka, ngatirege kusungirira chivakwa chekusungirira pabhesi, ndaizozviita sei kuti zvishande?
Paive neimwe nzira yekutyora iyo kubatana?
Ungabatirira pachinhu usina chawakanamatira pachiri here?
Iwo waiita semubvunzo usina musoro kubvunza asi pandakanga ndagadzira mubvunzo nenzira iyoyo ndakauya nemhinduro inogoneka:-
Unogona kupesvedzera zvinhu pasina kubatana kwenyama kwavari ... kuburikidza neFIELD!
Ndaiziva nezve electric fields*, gravity fields*, nemagnetic fields*.Asi zvaizokwanisika here?Zvinganyatsoshanda here?
(* Sorutivi kunofadza kuona kuti sainzi yemazuva ano haisati yanyatsotsanangura kuti “simba riri kure” rinonyatsoshanda sei).
Zvakazoitika gare gare ichiri ndangariro yakajeka.
Ndakanga ndiri muwekishopu yangu yekumba uye pakanga pava pakati pehusiku uye nguva yekurara, asi handina kukwanisa kurwisa muedzo wekuedza zano idzva iri.
Nenguva isipi ndakawana magineti ebhiza nechidimbu cheshim brass.Ndakaisa shim brass pakati pemagineti ne'muchengeti' wayo ndokukotama ndarira nechigunwe!
Eureka!Zvakashanda.Iyo ndarira yaingova 0.09mm gobvu asi musimboti wakasimbiswa!
(Mufananidzo uri kuruboshwe ndeyekuvakazve kwekuyedza kwekutanga asi uri kushandisa zvinhu zvakafanana).
Ndakafara nekuti ndakaona, kubva pakutanga, kuti kana iyo pfungwa yaigona kuitwa kuti ishande nenzira inoshanda saka yaizomiririra pfungwa nyowani mukugadzira sheetmetal.
Zuva rakatevera ndakaudza wandaishanda naye, Tony Grainger, nezvepfungwa dzangu.Aivewo nekakufadzwa uye akandirongera dhizaini ringaite remagetsi.Akaitawo mamwe masvomhu maererano nemhando yemasimba anogona kuwanikwa kubva kune electromagnet.Tony ndiye munhu akangwara wandaiziva uye ndakaita rombo rakanaka kuva naye semunhu wandaishanda naye uye nekuwana hunyanzvi hwake hwakakura.
Zvakanaka pakutanga zvaiita sekunge zano racho raingoshanda kune akatetepa geji esheetmetal asi yaivimbisa zvakakwana kundikurudzira kuti ndienderere mberi.
Early Development:
Pamazuva mashoma akatevera ndakawana zvimedu zvesimbi, imwe waya yemhangura, uye yekugadziridza uye ndakavaka yangu yekutanga electro-magnetic folda!Ndichiri nayo muwekishopu yangu:
Chikamu che electro-magnet chemuchina uyu ndicho chaicho chepakutanga.
(Iyo danda repamberi uye danda rekukotama rinoratidzwa pano rakazogadziridzwa gare gare).
Kunyangwe zvisizvo muchina uyu wakashanda!
Sezvaifungidzirwa munguva yangu yepakutanga eureka, chokwadi bhaa yekurovera yaisafanira kusungirirwa pagadziko remuchina kumigumo, kumashure, kana kupi zvako.Saka muchina uyu waive wakavhurika zvachose uye wakavhurika huro.
Asi iyo yakavhurika-yakapera chimiro chaigona chete kunyatso zivikanwa kana hinji dzedanda rekukotama dzaivewo dzisina kujairika.
Mumwedzi yaitevera ndakashanda parudzi rwehalf-hinge yandakadaidza kuti 'cup-hinge', ndakavaka muchina wekuita zvirinani (Mako II), ndakaisa Provisional Patent Specification neAustralia Patent Office uye ini ndakaonekawo pa. chirongwa cheterevhizheni cheABC chinonzi "The Inventors".Kugadzirwa kwangu kwakasarudzwa semukundi kwesvondo iroro uye ndokuzosarudzwa semumwe wevakakunda mugore iroro (1975).
Kuruboshwe ndiko Mark II bender sezvakaratidzwa muSydney zvichitevera kuonekwa kwekupedzisira kweThe Inventors.
Yakashandisa imwe vhezheni yakagadziridzwa ye'cup hinge' sezvakaratidzwa pazasi:
Munguva ya1975 ndakasangana naGeoff Fenton pamusangano weInventors Association muHobart (3 Nyamavhuvhu 1975).Geoff aifarira chaizvo kugadzirwa kwe "Magnabend" uye akadzoka kunzvimbo yangu mushure memusangano kuti anyatsozvitarisisa.Uku kwaizova kutanga kwehushamwari husingagumi naGeoff uye gare gare kudyidzana kwebhizimisi.
Geoff akanga apedza kudzidza muEngineering uye mugadziri akachenjera zvikuru pachake.Akabva angoona kukosha kwekuve nehinge dhizaini yaizobvumira muchina kuti uone kugona kwayo kuzere.
Yangu 'cup hinge' yakashanda asi yaive nematambudziko akakomba emakona emakona zvakanyanya kupfuura 90 degrees.
Geoff akatanga kufarira zvikuru mahinji asina pakati.Iyi kirasi yehinge inogona kupa pivoting yakatenderedza chaiyo poindi iyo inogona kunge iri kunze kwehinge michina pachayo.
Rimwe zuva (1 Kukadzi 1976) Geoff akasvika aine dhirowa yehinge isingawanzo uye inotaridzika.Ndakashamisika!Ndakanga ndisati ndamboona chinhu chiri kure chakadaro!
(Ona mufananidzo uri kuruboshwe).
Ndakadzidza kuti iyi yakagadziridzwa pantograph meshini inosanganisira 4-bar linkages.Hatina kumbobvira taita vhezheni chaiyo yehinge iyi asi mwedzi mishoma gare gare Geoff akauya neshanduro yakagadziridzwa yatakaita.
Chikamu chakachinjika cheshanduro yakagadziridzwa inoratidzwa pazasi:
'Maoko' ehinge iyi anochengetwa akaenzanirana nenhengo huru dzepivoting nema cranks madiki.Izvi zvinogona kuonekwa mumifananidzo iri pasi apa.Iwo cranks anongofanira kutora chikamu chidiki cheiyo yakazara hinge mutoro.
Kufananidza kweiyi michina inoratidzwa muvhidhiyo pazasi.(Ndinokutendai Dennis Aspo nekuda kwekufananidza uku).

Kunyangwe iyi hinge michina yakashanda zvakanaka, haina kumboiswa pamushini chaiwo weMagnabend.Zvipingamupinyi zvayo ndezvekuti haina kupa kutenderera kwakazara kwe180 dhigirii rekukotama uye zvakare yairatidzika kunge ine zvikamu zvakawanda mairi (kunyangwe mazhinji ezvikamu aive akafanana kune imwe neimwe).
Chimwe chikonzero nei hinge iyi isina kushandiswa ndechekuti Geoff akabva auya neyake:
Triaxial Hinge:
Iyo triaxial hinge yakapa 180 madhigirii akazara ekutenderera uye yaive yakapfava sezvo yaida mativi mashoma, kunyangwe zvikamu pachazvo zvaive zvakanyanya kuoma.
Iyo triaxial hinge yakafambira mberi nematanho akati wandei isati yasvika padhizaini yakagadzikana.Takadaidza marudzi akasiyana The Trunnion Hinge, The Spherical Internal Hinge uye The Spherical External Hinge.
Iyo spherical hinge yekunze inoteedzerwa muvhidhiyo iri pazasi (Ndinokutendai kuna Jayson Wallis nekufananidza uku):

Magadzirirwo ese aya anotsanangurwa mugwaro reUS Patent Specification.(PDF).
Imwe yematambudziko makuru neiyo Magnabend hinge yaive yekuti pakanga pasina pekuiisa!
Mapeto emuchina abuda nekuti tinoda kuti muchina uvhurike, saka unofanirwa kuenda kumwewo.Iko chaiko hakuna nzvimbo pakati pechiso chemukati chedanda rinokotama uye nechiso chekunze chedanda remberi remagineti.
Kugadzira nzvimbo isu tinogona kupa miromo padanda rekukotama uye padanda remberi asi miromo iyi inokanganisa kusimba kwedanda rekukotama uye simba rekurovera remagineti.(Unogona kuona iyi miromo mumifananidzo yepantograph hinge pamusoro).
Saka iyo hinge dhizaini inomanikidzwa pakati pekudikanwa kwekutetepa kuitira kuti miromo midiki chete inozodikanwa uye kudiwa kuve gobvu kuitira kuti ive yakasimba zvakakwana.Uye zvakare kukosha kwekusava nepakati kuitira kuti upe chaiyo pivot, zviri nani ingori pamusoro pebasa-pamusoro pemagineti.
Izvi zvinodikanwa zvakasvika pakureba kwazvo, asi dhizaini yaGeoff yakanyanya kugadzirisa zvinodiwa zvakanaka, kunyangwe basa rakawanda rebudiriro (rinowedzera anopfuura makore gumi) raidiwa kuti uwane kukanganiswa kwakanyanya.
Kana ndakumbirwa ndinogona kunyora chinyorwa chakasiyana pamahinji nekukura kwawo asi parizvino tichadzokera kunhoroondo:
