Zeziphi iingxaki ekufuneka ziqwalaselwe xa kufakwa idayali kunye ne-cylinder cambox?

Xa ufaka i-cambox, qala ngononophelo ujonge umsantsa phakathi kwe-cambox nganye kunye nesilinda (i-dial) (ingakumbi emva kokuba isilinda itshintshiwe), kwaye ufake i-cambox ngokulandelelana, ukuze kuthintelwe umahluko phakathi kwe-cambox ethile kunye nesilinda okanye i-dial. Xa umsantsa phakathi kwezilinda (i-dial) umncinci kakhulu, ngokuqhelekileyo ukungasebenzi kakuhle koomatshini ngexesha lokuveliswa.

Ungayilungisa njani isithuba esiphakathi kwesilinda (i-dial) kunye nekhamera?

1 Lungisa umsantsa phakathi kwedayali kunye nekhamera

Njengoko kubonisiwe kumfanekiso olandelayo, okokuqala, khulula iinuts kunye neeskrubhu ezahlulwe ngokulinganayo kwiindawo ezintandathu kwisiphelo esiphezulu se-mid core kunye nesangqa sangaphandle sesiphelo esiphezulu se-mid kernel zibe ziindawo ezintathu B. Emva koko, skrubhula iiskrubhu kwindawo A ngelixa Kwangaxeshanye, jonga umsantsa phakathi kwe-dial kunye ne-cam nge-feeler gauge, kwaye wenze phakathi kwe-0.10~0.20mm, kwaye uqinise iiskrubhu kunye neenuts zeendawo ezintathu B, uze ujonge kwakhona iindawo ezintandathu. Ukuba kukho naluphi na utshintsho, phinda le nkqubo kwaye wazi ukuba umsantsa ufanelekile. de.

2 Ukulungiswa komsantsa phakathi kwesilinda kunye nekhamera

Indlela yokulinganisa kunye neemfuno zokuchaneka ziyafana "nokulungiswa komsantsa ophakathi kwedayali kunye nekham". Ukulungiswa komsantsa kwenziwa ngokulungelelanisa isangqa sokuma sekham pile sesangqa esisezantsi sekhambox ejikelezayo ukuze i-radial runout embindini wethrekhi yentsimbi ibe ngaphantsi okanye ilingane ne-0.03mm. Umatshini ulungisiwe ngaphambi kokuba uphume efektri kwaye ufake iiphini zokubeka. Ukuba ukuchaneka kwendibano kutshintshiwe ngenxa yezinye izizathu, isangqa sokumisa sinokulinganiswa kwakhona ukuqinisekisa ukuchaneka kwesithuba esiphakathi kwesilinda yenaliti kunye nekham.

Ungayikhetha njani ikhamera?

I-cam yenye yezona ndawo ziphambili kumatshini wokuluka ojikelezayo. Umsebenzi wayo ophambili kukulawula intshukumo kunye nokuhamba kweenaliti zokuluka kunye nee-sinker. Ingahlulwahlulwa ibe yi-knit cam (i-loop forming) kunye ne-tuck cam, i-miss cam (umgca odadayo) kunye ne-sinker cam.

Umgangatho uphela wekham uya kuba nefuthe elikhulu kumatshini wokuluka ojikelezayo kunye nelaphu. Ke ngoko, nika ingqalelo ekhethekileyo kula manqaku alandelayo xa uthenga ikham:

Okokuqala, kufuneka sikhethe i-cam curve ehambelanayo ngokweemfuno zelaphu ezahlukeneyo kunye namalaphu. Njengoko abayili belandela iindlela ezahlukeneyo zelaphu kwaye begxila kumalaphu ahlukeneyo, i-cam working surface curve iya kwahluka.

Okwesibini, ekubeni inaliti yokuluka (okanye isinki) kunye nekhamera zikwi-high-speed sliding friction ixesha elide, iindawo zenkqubo nganye kufuneka zimelane neempembelelo eziphezulu ngexesha elinye, ngoko ke inkqubo yonyango lwezinto kunye nobushushu bekhamera ibaluleke kakhulu. Ke ngoko, izinto eziluhlaza zekhamera zihlala zikhethwa kwi-Cr12MoV yamazwe ngamazwe (umgangatho waseTaiwan/umgangatho waseJapan weSKD11), onokukwazi ukuqina kakuhle kunye nokuguquguquka okuncinci kokucima, kwaye ubunzima, amandla kunye nokuqina emva kokucima zifanelekile ngakumbi kwiimfuno zekhamera. Ubunzima bokucima bekhamera ngokubanzi yi-HRC63.5±1. Ukuba ubunzima bekhamera buphezulu kakhulu okanye buphantsi kakhulu, kuya kuba nesiphumo esibi.

Ngaphezu koko, uburhabaxa bomphezulu wokusebenza we-cam curve bubaluleke kakhulu, bumisela ngokwenene ukuba i-cam kulula ukuyisebenzisa kwaye ihlala ixesha elide. Uburhabaxa bomphezulu wokusebenza we-cam curve bumiselwa zizinto ezibanzi ezifana nezixhobo zokucubungula, izixhobo zokusika, iteknoloji yokucubungula, ukusika, njl. (Abavelisi ngabanye banamaxabiso aphantsi kakhulu angama-triangular, kwaye bahlala besenza ingxolo kweli khonkco). Uburhabaxa bomphezulu wokusebenza we-cam curve buqhele ukuchazwa njenge-Ra≤0.8μm. Uburhabaxa obubi bomphezulu buya kubangela ukugaywa kweenaliti, ukujova, kunye nokufudunyezwa kwe-cambox.

Ukongeza, qwalasela indawo ehambelanayo kunye nokuchaneka kwendawo yomngxuma wekhamera, indawo yokubeka izitshixo, imilo kunye negophe. Ukungazinaki ezi zinto kunokuba nemiphumo emibi.

Kutheni ufunda nge-cam curve?

Kuhlalutyo lwenkqubo yokwenza iluphu, ungabona iimfuno ze-engile yokugoba: ukuqinisekisa uxinzelelo oluphantsi lokugoba, i-engile yokugoba kufuneka ibethelwe, oko kukuthi, kungcono ukuba nee-sinkers ezimbini kuphela eziza kuthatha inxaxheba ekugobeni, ngeli xesha ukugoba I-engile ibizwa ngokuba yi-engile yenkqubo yokugoba; ukuze kuncitshiswe amandla okuchaphazela kwe-needle butt kwi-cam, i-engile yokugoba kufuneka ibe ncinci. Ngeli xesha, i-engile yokugoba ibizwa ngokuba yi-engile yomatshini yokugoba; ngoko ke, kwiimbono ezahlukeneyo zenkqubo kunye noomatshini, ezi mfuno zimbini ziyaphikisana. Ukuze kusonjululwe le ngxaki, kwavela ii-cams ezigobileyo kunye nee-sinkers zokunyakaza ezinxulumeneyo, ezinokwenza i-engile yokunxibelelana kwe-needle butt ne-engile ibe ncinci, kodwa i-engile yokuhamba inkulu.
