Yenziwa kwaye Yasetyenziswa Njani Imithombo Yolwandiso Olude?
Udinga amandla okutsala kumgama omde, kodwa imithombo eqhelekileyo mifutshane kakhulu. Ukuzidibanisa akukhuselekanga, kwaye ukusebenzisa indawo engalunganga kunokubangela ukuba inkqubo yakho yonke isilele.
Intwasahlobo yokwandiswa kwexesha elide yintwasahlobo eyenziwe ngokwezifiso kunye nomlinganiselo ophezulu wobude ukuya kububanzi, yenzelwe izicelo ezifuna uxinzelelo kumgama omkhulu. Bafuna ingqalelo ekhethekileyo ukuzinza kwezinto, ukuqina koxinzelelo lokuqala, kunye nesikhokelo sokuthintela ukugoba ngexesha lokusebenza.
Emsebenzini wam, I've seen that you cannot simply "stretch" uyilo oluqhelekileyo lwasentwasahlobo ukuyenza ibe nde. As soon as a spring's body length becomes many times its diameter, ukuziphatha kwayo kutshintsha ngokupheleleyo. Iqala ukusebenza kancinci njengentwasahlobo eyomeleleyo kwaye ngakumbi njengentambo yentsimbi. Olu tshintsho lwazisa iseti entsha yemingeni yobunjineli ekufuneka isonjululwe ukuqinisekisa ukuba intwasahlobo ikhuselekile, inokuthenjwa, kwaye yenza umsebenzi wayo ngokuchanekileyo kumgama wayo wonke wokuhamba.
Eyona nto ifanelekela iSpring Extension njenge "inde"?
Igama elithi "inde" kubonakala kuxhomekeke xa ujonga imithombo. How do you know if you need a standard spring or if you've crossed the line into a "long spring" uyilo?
Intwasahlobo ngokuqhelekileyo ithathwa "inde" xa ubude bomzimba wayo bungaphezulu kokuphindwe kashumi kobubanzi bayo obungaphandle (a 10:1 umlinganiselo). Lo mlinganiselo uphezulu yeyona nto iphambili eyazisa imingeni yoyilo olulodwa, njengomngcipheko ophezulu wokudityaniswa, ukungcangcazela, and distortion under load.
Ndihlala ndisebenzisa oku 10:1 umlinganiselo njengesiqalo xa uxoxa ngeprojekthi entsha kunye nenjineli. Below that ratio, Imigaqo yoyilo eqhelekileyo yasentwasahlobo idla ngokusebenza ngaphandle komcimbi. Kodwa xa sihamba ngaphaya kwayo, kufuneka siqale ukucinga ngendlela eyahlukileyo. Inde, slender spring body can easily get caught on nearby components or even tangle with itself if it's not properly guided. Kwakhona kufuneka siqwalasele ukungcangcazela kwe-harmonic. Kanye njengentambo yesiginci, intwasahlobo ende inokungcangcazela ngamaza athile, nto leyo enokubangela ukudinwa kwangaphambi kwexesha kunye nokusilela. These are problems you just don't see in shorter, imithombo ngakumbi compact.
More Than Just Length
Umlinganiselo wobude ukuya kububanzi yinto ebalulekileyo elawula indlela yobunjineli.
- I 10:1 Isikhokelo: Ngelixa ingengomgaqo ongqongqo, lo mlinganiselo luphawu olusekwe kakuhle kushishino lwasentlakohlaza. Ibonisa indawo apho ukungazinzi okunokwenzeka kuba yinkxalabo yoyilo oluphambili.
- Uzinzo kunye neSikhokelo: Intlakohlaza ende kaninzi ayinako ukuthwala ubunzima bayo ngaphandle kokugoba okanye ukugoba, ngakumbi xa ifakwe ngokuthe tye. Inokufuna intonga yesikhokelo ehamba embindini wayo okanye umjelo wokuhamba ngaphakathi ukuyinqanda ekubambeni kwezinye iindawo zendibano..
- Ukungcangcazela kunye neeHarmonics: Ukuba nde kwentwasahlobo, okuye kusezantsi ukuphindaphinda kwayo kwendalo. Kumatshini osebenza ngesantya esiphezulu, oku kunokukhokelela kwi-resonance, apho intwasahlobo ingcangcazela ngokungalawulekiyo, okukhokelela ekugugeni ngokukhawuleza kunye nokungaphumeleli.

Kutheni iMithombo yoLwandiso olude inzima kangaka nje ukuyenza?
You'd think making a long spring is easy—just let the coiling machine run for longer. Kodwa enyanisweni, ukugcina umgangatho kulo ubude ngumngeni omkhulu.
Ukuvelisa imithombo yokwandisa ixesha elide kunzima kuba ukugcina i-pitch engaguqukiyo kunye noxinzelelo lokuqala kubude bonke kunzima kakhulu.. Naluphi na utshintsho oluncinci kuxinzelelo lwecingo okanye isantya somatshini siyandiswa, okukhokelela ekusebenzeni okungahambelaniyo kunye neendawo ezinokuthi zibe buthathaka entwasahlobo.
Kumatshini wethu wokudibanisa we-CNC, yonke inxalenye yenkqubo ilawulwa ngekhompyutha, ukusuka kwisantya sokutya kocingo ukuya kwindawo yokujiya. Ngentwasahlobo emfutshane, inkqubo iphelile ngomzuzwana. For a spring that's several feet long, umatshini kufuneka ugcine ukuhambelana okugqibeleleyo ixesha elide kakhulu. Ukuxinana kocingo njengoko isitya kwi-spool kufuneka ihlale ingatshintshi. Ukuba idipha okomzuzwana, ingcinezelo yokuqala kwelo candelo lentwasahlobo iya kuba ngaphantsi. Ukuba iyanda, iikhoyili ziya kuba nzima kakhulu. Ezi mpazamo zincinci zinokudibanisa, creating a spring that doesn't pull with a uniform force. Emva kokudibanisa, ukuphatha le mithombo nako kulucelomngeni. Zinokolulwa lula okanye zibhijene phambi kokuba zide zifike kwi-oveni yonyango lobushushu.
Ucelomngeni lokungaguquguquki
Ukuchaneka ngundoqo, and it's much harder to maintain over a greater distance.
- Ulawulo Loxinzelelo Lokuqala: La mandla abambe iikhoyili kunye. Kwintwasahlobo ende, kufuneka siqinisekise ukuba la mandla ayafana ukusuka kwikhoyili yokuqala ukuya kowokugqibela. Oku kufuna useto lomatshini oluzinzileyo kunye nomgangatho wocingo ongaguqukiyo. Ukungahambelani koxinzelelo lokuqala kuthetha ukuba intwasahlobo ayiyi kubonelela ngokugudileyo, tsala yomgca.
- Ukufana kwePitch: Isithuba phakathi kweekhoyili (isandi) kufuneka ichaneke. Kwintwasahlobo ende, ukuguquguquka kobushushu kucingo okanye kumatshini kunokubangela ukuba i-pitch ikhukuliseke, echaphazela izinga lentwasahlobo.
- Ukuphatha kunye noNyango loBushushu: Inde, intwasahlobo ekrwada ithambile. Kufuneka ihanjiswe ngononophelo kwii-ovens zokunciphisa uxinzelelo. Ukuba igobile okanye yoluliwe phambi kokuba unyango lobushushu, isiphene siya kubekwa ngokusisigxina kwizinto eziphathekayo, ukonakalisa inxalenye.
| Inyathelo Lokuvelisa | Umngeni oMgangatho waseNtwasahlobo | Umngeni omde waseNtwasahlobo |
|---|---|---|
| Ukujija | Ukuseta okusisiseko kunye nokucwangcisa. | Ukugcina ukungaguquguquki okugqibeleleyo ngexesha elide. |
| Uxinzelelo lokuqala | Kulula ukugcina iyunifomu. | Ukuhluka koomatshini abancinci kunokubangela ukungahambelani okukhulu. |
| Ukuphatha | Ilula kwaye ithe ngqo. | Umngcipheko ophezulu wokudibanisa, ukolula, okanye ukugoba. |
