Indlela yokuthambisa i-roller chain inefuthe njani ekukhetheni?

Indlela yokuthambisa i-roller chain inefuthe njani ekukhetheni?

Ngokwezibalo zoshishino, malunga nama-60% okusilela kwe-roller chain ngaphambi kwexesha kungenxa yokuthambisa okungafanelekanga. Ukukhetha indlela yokuthambisa akusiyo "inyathelo emva kokulungiswa" kodwa yinto ephambili ekufuneka iqwalaselwe kwasekuqaleni. Nokuba kukuthunyelwa kwamanye amazwe kwimizi-mveliso, oomatshini bezolimo, okanye ekulungisweni kokutya, ukungawunaki ukuhambelana kwendlela yokuthambisa neempawu ze-chain kunokunciphisa kakhulu ubomi be-chain kwaye konyuse iindleko zokusebenza, nokuba kusetyenziswe imodeli kunye nezinto ezifanelekileyo. Eli nqaku liza kwahlulahlula iindlela zokuthambisa, lihlalutye impembelelo yazo ephambili ekukhetheni, kwaye libonelele ngeendlela zokukhetha ezisebenzayo ukukunceda uphephe iimpazamo eziqhelekileyo zokukhetha kwimisebenzi yokuthumela ngaphandle.

1. Ukuqonda Umahluko Ophambili Phakathi Kweendlela Ezine Eziphambili Zokuthambisa I-Roller Chain
Ngaphambi kokuba sixoxe ngokukhetha, kubalulekile ukuchaza ngokucacileyo imida efanelekileyo yeendlela ezahlukeneyo zokuthambisa. Ukusebenza kakuhle kwazo kokubonelela ngeoyile, ukulungelelana nokusingqongileyo, kunye neendleko zokulungisa zimisela ngokuthe ngqo "iimpawu zangaphakathi" ezifunekayo kwikhonkco.

1. Ukuthambisa ngesandla (Ukuthambisa/Ukubrasha)
Umgaqo: I-lubricant isetyenziswa rhoqo kwiindawo zokungqubana ezifana nee-chain pins kunye nee-rollers kusetyenziswa ibrashi okanye i-oiler.
Iimpawu eziphambili: Iindleko eziphantsi zezixhobo kunye nokusebenza okulula, kodwa ukuthambisa okungalinganiyo (okunokuthambekela "ekuthambiseni kakhulu" okanye "ekuthambiseni ngaphantsi") kunye nokungabikho kokuthambisa okuqhubekayo zixhaphakile.
Izicelo Ezisebenzayo: Iindawo ezivulekileyo ezinesantya esiphantsi (isantya esithe tyaba < 0.5 m/s) kunye nemithwalo elula (imithwalo < 50% yomthwalo olinganisiweyo), njengee-conveyors ezincinci kunye nee-manual lifts.

2. Ukuthambisa ngeOyile (iOyile Dripper)
Umgaqo: I-oil dripper etyalwe ngamandla adonsela phantsi (enevalvu yokulawula ukuhamba kwamanzi) ithontsiza isixa esimiselweyo se-lubricant kwi-chain friction pair. I-oiling frequency ingahlengahlengiswa ngokweemeko zokusebenza (umz., i-1-5 drops/minute).
Iimpawu eziphambili: Ukuthambisa ngokulinganayo kunye nokuthambisa okujoliswe kwiindawo eziphambili kunokwenzeka. Nangona kunjalo, le ndlela ayifanelekanga ukusetyenziswa ngesantya esiphezulu (amathontsi eoyile akhutshwa lula ngamandla e-centrifugal) kwaye ifuna ukuzaliswa rhoqo kwetanki yeoyile. Ukusetyenziswa Okusebenzayo: Iindawo ezivalekileyo kancinci ezinesantya esiphakathi (0.5-2 m/s) kunye nemithwalo ephakathi, njengeetsheyini zokuqhuba izixhobo zomatshini kunye neetsheyini ezincinci zefeni.

3. Ukuthambisa ngeoyile (Ukuthambisa ngokuntywiliselwa)
Umgaqo: Inxalenye yetsheyini (idla ngokuba yitsheyini esezantsi) ifakwa kwindawo yokugcina ioyile etyibilikayo kwibhokisi evaliweyo. Ngexesha lokusebenza, ioyile ithwalwa ziiroli, ukuqinisekisa ukuthambisa okuqhubekayo komphezulu wokungqubana kwaye ikwabonelela ngokusasazwa kobushushu.
Iimpawu eziphambili: Ukuthambisa okwaneleyo kunye nokucoca ubushushu okugqwesileyo, okususa isidingo sokuphinda kuzaliswe ioyile rhoqo. Nangona kunjalo, itsheyini inokumelana okuphezulu kokusebenza (inxalenye entywilisiweyo ichatshazelwa kukumelana neoyile), kwaye ioyile ingcoliswa lula bubumdaka kwaye ifuna ukutshintshwa rhoqo.
Izicelo Ezisebenzayo: Iindawo ezivalekileyo ezinesantya esiphezulu (2-8 m/s) kunye nemithwalo enzima, njengeetyathanga ezingaphakathi kwezixhobo zokunciphisa kunye neetyathanga zeebhokisi ezinkulu zegiya.

4. I-Spray Lubrication (I-High-Pressure Oil Mist)
Umgaqo: Ioyile yokuthambisa ifakwa kwi-atom ngepompo yoxinzelelo oluphezulu kwaye itshizwe ngqo kumphezulu wokungqubana kwetyathanga nge-nozzle. I-oyile yokuthambisa inamasuntswana amancinci (5-10 μm) kwaye inokugubungela izakhiwo ezintsonkothileyo ngaphandle kokumelana okongezelelweyo. Iimpawu eziphambili: Ukusebenza kakuhle kokuthambisa kunye nokuzivumelanisa nezicelo zesantya esiphezulu/ubushushu obuphezulu. Nangona kunjalo, kufuneka izixhobo zokutshiza ezikhethekileyo (ezibiza kakhulu), kwaye i-oyile yokuthambisa kufuneka ibuyiselwe ukuze kuthintelwe ungcoliseko lokusingqongileyo.

Izicelo Ezisebenzayo: Isantya esiphezulu (>8 m/s), ubushushu obuphezulu (>150°C), okanye iindawo ezivulekileyo ezinothuli, ezifana neetsheyini zokutyumza zemigodi kunye neetsheyini zokuqhuba oomatshini bokwakha.

II. Isitshixo: Iimpembelelo Ezintathu Ezichonga Indlela Yokuthambisa Ekukhetheni I-Roller Chain

Xa ukhetha i-roller chain, umgaqo oyintloko "kukumisela indlela yokuthambisa kuqala, emva koko iiparameter ze-chain." Indlela yokuthambisa imisela ngokuthe ngqo izinto ze-chain, uyilo lwesakhiwo, kwaneendleko zokugcina emva koko. Oku kubonakala kwiinkalo ezintathu ezithile:

1. Unyango lwezinto kunye nomphezulu: "Umda osisiseko" wokuhambelana nendawo yokuthambisa
Iindlela ezahlukeneyo zokuthambisa zihambelana neempawu ezahlukeneyo zokusingqongileyo, kwaye izinto zetsheyini kufuneka zibe nokunyamezelana okuhambelanayo:

Ukuthambisa nge-oyile/ukutshiza nge-oyile: Xa usebenzisa izithambisi zoshishino ezifana ne-oyile yeminerali kunye ne-oyile yokwenziwa, ikhonkco lichaphazeleka yi-oyile kunye nokungcola. Kufuneka kukhethwe izinto ezimelana nomhlwa, ezifana ne-galvanized carbon steel (yokusetyenziswa ngokubanzi) okanye i-stainless steel (kwiindawo ezifumileyo okanye ezirhabaxa kancinci). Kwizicelo zobushushu obuphezulu (>200°C), kufuneka kukhethwe iintsimbi ze-alloy ezimelana nobushushu (ezifana ne-Cr-Mo steel) ukuze kuthintelwe ukuthamba ngenxa yobushushu obuphezulu. Ukuthambisa ngesandla: Ukuze kusetyenziswe kwishishini lokutya (umz., abathuthi bokutya), kufuneka kukhethwe izinto ezihambelana nomgangatho wokutya (umz., i-stainless steel engama-304), kwaye umphezulu kufuneka upholishwe ukuthintela intsalela ye-lubricant kunye nokukhula kweebhaktheriya. Kufuneka kusetyenziswe nezithambisi ze-food-grade (umz., i-oyile emhlophe).

Indawo enothuli + Ukuthambisa ngeSpray: Uthuli lunamathela lula kumphezulu wetsheyini, ngoko ke unyango lomphezulu olumelana nokuguguleka (umz., ukugalela i-carburizing, ukucima, okanye i-phosphating) luyafuneka ukuthintela uthuli ekudibaneni netsheyini ukuze kwenziwe “izinto ezirhabaxa” kwaye kukhawuleziswe ukuguguleka kwetsheyini.

2. Uyilo lweSakhiwo: Ukuthelekisa indlela yokuthambisa sisiSiseko sokuSebenza kakuhle
Iinkcukacha zesakhiwo setsheyini kufuneka "zisebenze" ngendlela yokuthambisa; kungenjalo, ukuthambisa kuya kusilela.

Ukuthambisa ngesandla: Akufuneki ulwakhiwo oluntsonkothileyo, kodwa kufuneka i-chain pitch enkulu (>16mm) kunye nendawo efanelekileyo yokuvula. Ukuba i-pitch incinci kakhulu (umz., ingaphantsi kwe-8mm), ukuthambisa ngesandla kuya kuba nzima ukungena kwisibini sokungqubana, nto leyo edala "amabala okuthambisa angabonakaliyo." Ukuthambisa nge-oyile: Kufuneka kusetyenziswe isikhuselo esivaliweyo ukuthintela ukuvuza kwe-oyile kunye nokungcola ukuba kungangeni, kwaye ikhonkco kufuneka lenziwe ngomjelo wesikhokelo seoyile ukuze ibuyisele ioyile kwindawo yokugcina ioyile, ukunciphisa inkunkuma. Ukuba ikhonkco lifuna ukugoba ecaleni, kufuneka kugcinwe indawo yokuhamba kweoyile ngaphakathi kwesikhuselo.

Ukuthambisa nge-spray: Itsheyini kufuneka yenziwe ngeepleyiti zetsheyini ezivulekileyo (ezifana neepleyiti zetsheyini ezingenanto) ukuthintela ukuba inkungu yeoyile ingavalwa ziipleyiti zetsheyini kwaye ithintele ukuba ingafikeleli kumphezulu wokungqubana phakathi kwee-pins kunye nee-roller. Ukongeza, kufuneka kubekho iindawo zokugcina ioyile kuzo zombini iziphelo ze-chain pins ukugcina okwethutyana inkungu yeoyile kunye nokwandisa ukusebenza kakuhle kokuthambisa.

3. Ukuhambelana kweMeko yokusebenza: Kumisela "uBomi bokwenyani beNkonzo" yeTyeya

Ukukhetha indlela yokuthambisa engalunganga kwitsheyini elungileyo kunokunciphisa ngokuthe ngqo ubomi benkonzo yetsheyini ngaphezulu kwama-50%. Iimeko eziqhelekileyo zezi zilandelayo:

Impazamo 1: Ukukhetha "ukuthambisa ngesandla" kwityathanga elikhawulezayo (10 m/s) - Ukuthambisa ngesandla akukwazi ukuhambelana neemfuno zokungqubana kokusebenza ngesantya esiphezulu, nto leyo ebangela ukuguguleka kweroli kunye nokubanjwa kwephini kwisithuba senyanga. Nangona kunjalo, ukukhetha ukuthambisa ngesitshizi ngeepleyiti zetyathanga ezingenanto kunokwandisa ubomi benkonzo ukuya kwiminyaka emi-2-3. Ingcamango ephosakeleyo yesi-2: Ukukhetha "ukuthambisa ngeoyile" kwiityathanga kwishishini lokutya—iibhafu zeoyile zinokugcina intsalela yeoyile ngaphakathi kwekhaka, kwaye utshintsho lweoyile lunokungcolisa ukutya ngokulula. Ukukhetha "ukuthambisa ngesandla ngetyathanga lentsimbi engagqwali engama-304" ngethanjisi yomgangatho wokutya kuhlangabezana nemigangatho yococeko kwaye kunika ubomi obungaphezulu kweminyaka eli-1.5.

Ingcamango ephosakeleyo 3: Ukukhetha "intsimbi yekhabhoni eqhelekileyo ene-drip lubrication" kwiitsheyini ezikwiindawo ezifumileyo—i-drip lubrication ayigubungeli ngokupheleleyo umphezulu wetsheyini, kwaye umoya ofumileyo unokubangela umhlwa. Ukukhetha "intsimbi yekhabhoni egalelwe nge-galvanized ene-oil bath lubrication" (indawo evaliweyo ihlukanisa umswakama) kunokuthintela umhlwa.

III. Ukusetyenziswa Okusebenzayo: Isikhokelo Samanyathelo Amane Sokukhetha I-Roller Chain Ngokusekelwe Kwindlela Yokuthambisa
Ukwazi la manyathelo alandelayo kuya kukunceda ulungelelanise ngokukhawuleza "indlela yokuthambisa - iiparameter zetyathanga" kwaye uphephe iimpazamo zokukhetha ngexesha loku-odola ukuthumela ngaphandle:
Inyathelo 1: Chonga iiparameter ezintathu eziphambili zesimo sesicelo
Okokuqala, qokelela ulwazi malunga neemeko zokusebenza komthengi; le yimfuneko yokumisela indlela yokuthambisa:
Iiparameter zokusebenza: isantya esithe ngqo setsheyini (m/s), iiyure zokusebenza zemihla ngemihla (h), uhlobo lomthwalo (umthwalo oqhubekayo/umthwalo wokothuka);
Iiparameters zokusingqongileyo: ubushushu (ubushushu obuqhelekileyo/obuphezulu/obuphantsi), ukufuma (okomileyo/ofumileyo), ukungcola (uthuli/ioyile/imidiya ekonakalisayo);
Iimfuno zoshishino: ingaba olu luhlu luyahlangabezana na nemigangatho ekhethekileyo efana nenqanaba lokutya (isatifikethi se-FDA), isiqinisekiso sokumelana nokuqhuma (isatifikethi se-ATEX), kunye nokukhuselwa kwendalo (isatifikethi se-RoHS).

Inyathelo lesi-2: Thelekisa indlela yokuthambisa ngokusekwe kwiiparameter
Ngokusekelwe kwiiparameters ezivela kwinyathelo loku-1, khetha indlela enye okanye ezimbini zokuthambisa ezinokubakho kwiindlela ezine ezikhoyo (jonga kwiimeko ezifanelekileyo kwicandelo loku-1). Imizekelo ibandakanya:
Imeko: Umthuthi wokutya (isantya esithe ngqo yi-0.8 m/s, ubushushu begumbi, isiqinisekiso se-FDA siyafuneka) → Ukhetho: Ukuthambisa ngesandla (ioyile yodidi lokutya);
Imeko: Isixhobo sokutyumza imigodi (isantya esithe tyaba yi-12 m/s, ubushushu obuphezulu yi-200°C, uthuli oluphezulu) → Ukhetho: I-spray lubrication (ioyile yokwenziwa enobushushu obuphezulu);
Imeko: Ukuhanjiswa kwezixhobo zomatshini (isantya esithe tyaba yi-1.5 m/s, indawo evalekileyo, umthwalo ophakathi) → Ukhetho: Ukuthambisa nge-oyile/Ukuthambisa nge-oyile ebhafini

Inyathelo lesi-3: Iiparameter zeThyinta yeSihluzo seZihluzo ngeNdlela yokuLubricate
Emva kokugqiba indlela yokuthambisa, gxila kwiiparameter ezine zekhonkco eliphambili:
Indlela Yokuthambisa, Izinto Ezicetyiswayo, Unyango Lomphezulu, Iimfuno Zolwakhiwo, kunye Nezixhobo
Ukuthambisa ngesandla: Intsimbi yeCarbon / 304 Intsimbi Engagqwaliyo, Epholishiweyo (Udidi lokutya), Ipitshi > 16mm, Akukho (okanye iOyile)
Ukuthambisa ngeOyile eNcitshisiweyo: Intsimbi yeCarbon / Intsimbi yeCarbon eGalathiweyo, ePhosphated / Emnyama, EneMingxunya yeOyile (Kulula Ukuyithambisa), Ukuthambisa ngeOyile
Ukuthambisa ngeoyile: Intsimbi yeCarbon Steel / Cr-Mo Steel, iCarburised neCenched, i-Enclosed Guard + Oil Guide, i-Oil Level Gauge, i-Oil Drain Valve
Ukuthambisa ngesitshizi: Intsimbi ye-alloy engangeni bushushu, i-coating engangeni manzi, ipleyiti ye-hollow chain + i-oyile reservoir, i-spray pump, isixhobo sokubuyisela

Inyathelo lesi-4: Ukuqinisekiswa kunye nokuphuculwa (Ukuphepha iingozi kamva)
Inyathelo lokugqibela lifuna ukuqinisekiswa kabini kumthengi nakumthengisi:
Qinisekisa kumthengi ukuba indlela yokuthambisa iyahlangabezana na neemfuno zezixhobo ezikhoyo kwindawo (umz., ukuba kukho indawo yezixhobo zokutshiza kunye nokuba ukuthambisa rhoqo kunokuzaliswa kwakhona);
Qinisekisa kumthengisi ukuba itshaneli ekhethiweyo ifanelekile na kule ndlela yokuthambisa. "Ixesha elilindelekileyo lokuphila" kunye "nomjikelo wolondolozo." Iisampulu kufuneka zinikezelwe ukuze kuvavanywe imeko yokusebenza ukuba kuyimfuneko.

Ingcebiso yokuphucula: Ukuba umthengi unebhajethi encinci, "isisombululo esingabizi kakhulu" sinokucetyiswa (umz., kwizicelo zesantya esiphakathi, ukuthambisa ngedriphu kubiza ngaphantsi ngama-30% kunezixhobo zokuthambisa ngesitshizi).

IV. Iimpazamo zoKhetho oluQhelekileyo kunye neeNgxaki zeShishini lokuThumela ngaphandle

Kwi-roller chain exports, ukungawunaki indlela yokuthambisa kukhokelela kwi-15% yembuyekezo kunye notshintshiselwano. Ezi mpazamo zintathu zilandelayo kufuneka ziphetshwe:

Impazamo 1: “Khetha imodeli yetsheyini kuqala, uze ucinge ngendlela yokuthambisa.”

Umngcipheko: Umzekelo, ukuba kukhethwe itshaneli ekhawulezayo (njenge-RS60), kodwa umthengi uvumela ukuthambisa ngesandla kuphela kwindawo leyo, itshaneli inokungasebenzi kwisithuba senyanga.

Iingxaki ekufuneka uziphephe: Cinga "ngendlela yokuthambisa" njengenyathelo lokuqala ekukhetheni. Bonisa ngokucacileyo "indlela yokuthambisa ecetyiswayo kunye neemfuno ezixhasayo" kwisicatshulwa ukuze kuthintelwe iingxabano kamva. Intsomi 2: "Indlela yokuthambisa ingatshintshwa kamva."
Umngcipheko: Umthengi uqala ngokusebenzisa i-lubrication ngesandla aze kamva afune ukutshintshela kwi-oil bath lubrication. Nangona kunjalo, i-chain ekhoyo ayinayo i-shield yokukhusela, nto leyo ebangela ukuvuza kwe-oil kunye nesidingo sokuthenga kwakhona i-chain entsha.
Ukuphepha: Ngexesha lokukhetha, yazisa umthengi kwangaphambili ukuba indlela yokuthambisa inxulumene nesakhiwo setsheyini, nto leyo eyenza iindleko zokutshintsha zibe phezulu. Ngokusekelwe kwisicwangciso sokuphucula umsebenzi womthengi seminyaka emithathu, cebisa itsheyini ehambelana neendlela ezininzi zokuthambisa (njengenye enekhaka elisuswayo).
Intsomi 3: “Iitsheyini zodidi lokutya zifuna kuphela ukuba izinto zihambelane nemigangatho; indlela yokuthambisa ayibalulekanga.”
Umngcipheko: Umthengi uthenga ityathanga lentsimbi engagqwaliyo engama-304 (izinto ezikumgangatho wokutya) kodwa usebenzisa igrisi eqhelekileyo yemizi-mveliso (umgangatho ongengowokutya), nto leyo ebangela ukuba imveliso ivalelwe ngabaphathi berhafu kwilizwe lalo mthengi.
Ukuphepha: Kwii-odolo zokuthumela ngaphandle kwishishini lokutya, qinisekisa ukuba zonke iinkalo ezintathu zezinto zetyathanga, i-lubricant, kunye nendlela yokuthambisa ziyahlangabezana nemigangatho yokutya kwaye zibonelele ngamaxwebhu esiqinisekiso afanelekileyo (afana nesiqinisekiso se-FDA okanye se-NSF).

Isishwankathelo
Ukukhethwa kwetyathanga le-roller akuyonto “yokufanisa iparameter enye” kodwa yindlela ecwangcisiweyo equka “indlela yokuthambisa, iimeko zokusebenza, kunye neempawu zetyathanga.” Kumashishini athumela kwamanye amazwe, ukukhetha ngokuchanekileyo akuphuculi nje kuphela ulwaneliseko lwabathengi (ukunciphisa imiba yasemva kokuthengisa) kodwa kubonisa nobungcali. Kaloku, abathengi abafuni nje “ityathanga,” bafuna “ityathanga eliza kusebenza ngokuzinzileyo kwizixhobo zabo iminyaka emi-2-3.”
