Namhlanje, siza kujonga inkqubo epheleleyo yokuvelisa ii-roller chains ze-12B, sichaza iinkcukacha zobugcisa ezingasemva kwale "roller chain esemgangathweni ophezulu."

1. Iziseko zeNkqubo: I-Standard Positioning kunye ne-Material Selection Logic ye-12B Roller Chain

Ngaphambi kokuba sihlolisise iinkcukacha zenkqubo, kubalulekile ukuba siqale sicacise "umlinganiselo wenkqubo" we-roller chain ye-12B. Njengoko i-transmission chain ihambelana ne-ANSI B29.1 (umgangatho we-American chain) kunye ne-ISO 606 (umgangatho we-international chain), ubukhulu bayo obuphambili, obufana ne-pitch (19.05mm), ububanzi be-roller (11.91mm), kunye nobubanzi be-inner segment (12.57mm), bubekwe emgangathweni kwaye buzinzile. Injongo ephambili yenkqubo kukufezekisa ukusebenza okuphezulu ngezixhobo kunye netekhnoloji yokucubungula ngelixa kuhlangatyezwana nale migangatho.

1. Ukukhethwa kokuhambelana kwenkqubo kwezinto eziphambili

Izinto ezahlukeneyo ze-12B roller chain zifuna izinto ezahlukeneyo kunye neenkqubo zangaphambi konyango ngenxa yeemeko zazo ezahlukeneyo zomthwalo:

Iiphini kunye neerola: Njengezinto eziphambili kwi-chain transmission ezimelana nefuthe kunye nokungqubana, i-SUJ2 high-carbon bearing chromium steel (elingana nentsimbi yasekhaya ye-GCr15) iyakhethwa. Izinto kufuneka kuqala zifakwe kwi-"spheroidizing annealing" pretreatment—ukufudumeza intsimbi ukuya kwi-780-820°C kangangeeyure ezi-4-6, emva koko ipholise kancinci ukuya ngaphantsi kwe-500°C. Le nkqubo inciphisa ubunzima bezinto (ubulukhuni beBrinell ≤ 207 HB), iphucula ukusebenza kwe-machinability, kwaye ibeka isiseko se-microstructure efanayo ngexesha lonyango lobushushu olulandelayo, ithintela ukuqhekeka ngexesha lokucima.

Iipleyiti zetyathanga kunye nee-bushings: Iipleyiti zetyathanga ziyafuneka ukuze zimelane nemithwalo yokutsalwa, ngoko ke kusetyenziswa intsimbi yesakhiwo ye-ST52-3 ene-carbon alloy ephantsi (amandla okutsalwa ≥ 520 MPa). Inkqubo "yokucima nokulungisa" (ukucima kulandelwa kukushisa okuphezulu) izisa ubunzima kwi-HB220-250, iqinisekisa amandla okutsalwa kunye nenqanaba elithile lokuqina ukuthintela ukwaphuka. Ii-bushings zenziwe ngentsimbi ye-carburised ye-20CrMnTi, kunye nenkqubo elandelayo ye-carburing yokwandisa ubunzima bomphezulu ukuze imelane nokutshayiswana okutyibilikayo ngeepini.

II. Inkqubo yoMveliso oPhambili: Utshintsho oluchanekileyo ukusuka "kwiZixhobo ezingasetyenzwanga" ukuya "kwiiKhonkco zeeChain"

Ukuveliswa kwee-roller chains ze-12B kubandakanya iinkqubo ezisibhozo eziphambili, nganye ifuna ulawulo oluqinileyo lweeparameter zenkqubo ukuqinisekisa ukuchaneka nokusebenza:

1. Unyango lwangaphambi kwezixhobo eziluhlaza: Ukucoca indlela yokucubungula

Ukususwa komhlwa kunye neoyile: Xa ingena kwindawo yokusebenzela, yonke intsimbi idluliselwa kuqala ngebhafu yokususa amafutha e-alkaline (50-60°C, ifunxwe imizuzu eli-15-20) ukuze kususwe ioyile engaphezulu. Emva koko ifakwa kwi-pickled nge-hydrochloric acid (15%-20% concentration, ifunxwe kubushushu begumbi imizuzu eli-8-12) ukuze kususwe isikali. Ekugqibeleni, ihlanjwa ngamanzi acocekileyo ize yomiswe ukuze kuthintelwe ukungcola ukuba kungachaphazeli ukuchaneka kokusetyenzwa okulandelayo.

Ukusika ngokuchanekileyo: Ngokuxhomekeke kubungakanani becandelo, ukusarha kwe-CNC okanye ukusika nge-laser kusetyenziswa ukusika. Ukunyamezela ubude bokusika ngephini kufuneka kulawulwe ngaphakathi kwe-±0.1mm, ngelixa ukusika ngepleyiti yetsheyini kufuneka kugcine ukuphambuka komlinganiselo we-≤0.05% ukuthintela ukuguquka ngexesha lokunyathela okulandelayo.

2. Ukulungisa ngokuchanekileyo iinxalenye eziphambili: Ukulungisa ngokuchanekileyo kwinqanaba le-millimeter

Ukunyathela kunye nokubhoboza ipleyiti yetyathanga: Ukunyathela kunye nokubhoboza ipleyiti yetyathanga kwenziwa kwi-CNC punch press kusetyenziswa "idayi eqhubekayo eqhubekayo." Umda wepleyiti yetyathanga uqala ngokubhoboza, kulandele imingxuma yephini kuzo zombini iziphelo. Ukunyamezelana kweendawo zemingxuma kufuneka kulawulwe ukuya kwi-H7 (uluhlu lokunyamezelana 0-0.018mm), kunye nempazamo yomgama wemingxuma ephakathi ye-≤0.05mm ukuqinisekisa ukulingana ngokuchanekileyo okulandelayo neephini. Ukususa i-burring (ukusebenzisa ivili lokusila okanye ukugoba okudlidlizayo) kuyadingeka emva kokunyathela ukuthintela imiphetho ebukhali ekwenzakaliseni abaqhubi okanye ukuphazamisana nokuhlanganiswa. I-Roller Cold Forging: Intsimbi ye-SUJ2 yenziwa kwinqanaba elinye kusetyenziswa umatshini wokufumba obandayo wezikhululo ezininzi. Intambo iqala yenziwe, emva koko ikhutshelwe kwimo yerola, kwaye ekugqibeleni igxothwe (ukuze ifakwe kwisingxobo). Ngexesha lenkqubo yokufumba obandayo, ubushushu bedayi (≤200°C) kunye noxinzelelo (300-400 MPa) kufuneka kulawulwe ukuqinisekisa ukuba impazamo yokujikelela kwerola yi-≤0.03mm ukuthintela ukuguguleka okungaqhelekanga ngexesha lokusebenza.
Ukugqitywa kwePin: Ipin iqale igutywe kusetyenziswa igrinder engenambindi (enomlinganiselo wangaphandle olingana no-±0.05mm), ize igutywe kakuhle ukuya kumlinganiselo wayo wokugqibela (ukunyamezelana no-H8, 0-0.022mm) kusetyenziswa igrinder esilinda. Uburhabaxa bomphezulu obuyi-Ra ≤0.8μm buyagcinwa. Lo mphezulu uthambileyo unciphisa ukungqubana okutyibilikayo kunye nesleeve, nto leyo eyandisa ubomi bawo benkonzo.

3. Unyango lobushushu: Ukunika "ukusebenza okuqinileyo" kwiinxalenye
Ukushisa iipleyiti zeTyayini: Emva kokunyathela, iipleyiti zetyayini zifakwa kwisithando sokucima esiqhubekayo, esibanjwe kwi-850-880°C imizuzu engama-30, emva koko zicinywe ngeoyile. Emva koko zifakwa kwisithando sokucima esishushu kwi-550-600°C iiyure ezi-2. Ubunzima bokugqibela bufikelela kwi-HB220-250, kwaye amandla okutsalwa anyuswa aye kwi-≥800 MPa, ukuqinisekisa ukuba zinokumelana nomthwalo wokutsalwa olinganiselweyo we-12B chain (≥18.8 kN). Ukucima iiPin kunye neRoller + Ukushisa okuphantsi: Iipin kunye neeroli zeSUJ2 zifudunyezwa ukuya kwi-830-850°C (ubushushu obubambe imizuzu engama-25) kwisithando sokucima esinebheli le-mesh, zicinywe ngeoyile, kwaye emva koko zicinywe ngobushushu obuphantsi kwi-160-180°C iiyure ezi-2, zifikelela kubunzima bomphezulu be-HRC 58-62 kunye nobunzima obuphambili be-HRC 30-35. Esi sakhiwo "sangaphandle esiqinileyo, esingaphakathi esiqinileyo" simelana nokuguguleka kunye nempembelelo yemiqamelo, sithintela ukwaphuka. Ukunyibilikisa kunye nokuCima imiqamelo: Isingxobo se-20CrMnTi sifakwa kwisithando somlilo esitshisiweyo kwaye sifudunyezwe kwi-920-940°C kangangeeyure ezi-4-6 nge-methanol kunye ne-propane (ii-carburizing agents) ukuze kufikelelwe kumxholo wekhabhoni engaphezulu kwe-0.8%-1.2%. Emva koko isingxobo siyacinywa (850°C sipholile ngeoyile) kwaye sifudunyezwe kubushushu obuphantsi (180°C). Ubunzima bomphezulu obuvelayo yi-HRC 58-62, kwaye ubunzulu bomaleko otshisiweyo yi-0.8-1.2mm, nto leyo eyandisa ubomi bokungqubana kwesingxobo ngokuchasene nephini.

4. Ukuhlanganiswa kweModular: Ukuqinisekisa ukulungelelaniswa kweTyathanga lilonke

I-Inner and Outer Link Assembly: I-inside link ine-sleeve, i-roller, kunye ne-inner link plate. Okokuqala, cinezela i-sleeve kwi-pin hole ye-inner link plate (ukulingana kokuphazamiseka, amandla okulingana nokucinezelwa 5-8kN). Emva koko, slayida i-roller phezu kwe-sleeve (ukulingana kokucima, ukususwa kwe-0.02-0.05mm). I-outer link ine-pin kunye ne-outer link plate. I-pin icinezelwa kwi-outer link plate (ukulingana kokuphazamiseka). Emva kokufakwa kwe-press-fitting, jonga ukuba ayitshintshi na (ukuphambuka ≤ 0.5°) ukuze uthintele ukubopha ngexesha lokusebenza.​
Ukuhlanganiswa kweTyathanga elipheleleyo kunye nokuSolula kwangaphambili: Amakhonkco angaphakathi nangaphandle adityaniswe ndawonye ukuze enze ityathanga elipheleleyo. Oku kulandelwa "lunyango lokusolula kwangaphambili" - amandla okutsalwa angama-80% omthwalo olinganisiweyo (malunga ne-15kN) asetyenziswa kumatshini wokuvavanya ukutsalwa ozinikeleyo imizuzu engama-30. Oku kususa ukunwebeka kokuqala kwetyathanga kwaye kuvumela ukuba izinto zivumelane ngakumbi. Oku kuvumela ukuba ukunwebeka okulandelayo kulawulwe ngaphakathi kwe-0.5% (xa kuthelekiswa nomndilili weshishini we-1%-1.5%).

III. Inkqubo yoLawulo loMgangatho: Ukuhlolwa kweNkqubo epheleleyo ukuze kupheliswe iimveliso ezingaphantsi komgangatho
