Entangawuuzi ze zisinga okunyweza mu kuyungibwa kw’ebyuma. Enkozesa yazo entuufu ekwata butereevu ku bulamu, okutebenkera, n’obulamu bw’ebikozesebwa. Mu nkola, okulonda, okuteeka, n’okulabirira entangawuuzi kulina okugoberera ebikwata ku by’ekikugu ebitongole okukakasa okuyungibwa okwesigika n’okwewala okulemererwa okuyinza okubaawo. Ekiwandiiko kino kijja kuwa obukodyo obukwata ku nkozesa y’entangawuuzi, okubikka okulonda, okuteeka, anti-okusiimuula, n’okuddaabiriza.
1. Obukodyo bw’okulonda entangawuuzi .
Okulonda entangawuuzi kyetaagisa okulowooza ennyo ku bintu ng’ebintu eby’okuyungibwa, ebyetaago by’omugugu, n’embeera y’okukola. Okusooka, londa nut ekwatagana ne bolt specifications, okukakasa thread size (okugeza, M8, M10) ne strength grade (okugeza, 8.8, 10.9) zikwatagana. Ekyokubiri, londa entangawuuzi ez’enjawulo ku mbeera ez’enjawulo ez’okukola:
Embeera y’okukola eya waggulu-Stress: Kozesa-amaanyi ga aloy ebyuma n’ebyuma eby’okunaaza okusaasaanya puleesa.
Embeera z’okukankana: zisinga kwagala anti-ezisiimuula entangawuuzi (nga nayirooni ziyingizaamu entangawuuzi oba okusiba entangawuuzi) oba ssaako ebyuma ebinaabiramu eby’omu nsenyi.
Embeera ezikosa: Kozesa obuti obutaliimu buwuka (nga 304 oba 316) oba zinc-obuteekeddwa oba dacromet-obuti obulongooseddwa okusobola okulongoosa okuziyiza okukulukuta.
Ate era, obuwanvu bwa nut bulina okukwatagana n’obuwanvu bwa bolt threading okwewala okusika obuwuzi oba obutalooka obutamala olw’obutaba na buwuzi bumala.
II. Obukodyo bw'okussaako entangawuuzi .
Obukodyo obutuufu obw’okussaako kyetaagisa okulaba ng’entangawuuzi ekola bulungi. Bino wammanga bye bifo ebikulu ebikola:
Preload Control: Kozesa ekisumuluzo kya torque okunyweza entangawuuzi ku muwendo ogulagirwa, okwewala okunyiga ennyo (ekiyinza okuleeta okukyukakyuka kw’obuwuzi) oba okunywezebwa wansi (ekiyinza okusumulula n’okulemererwa). Omutindo gw’amakolero ogw’awamu guwa empisa z’okujuliza torque; Okugeza, torque esengekeddwa ku M10 bolt eri 40-60 N·m.
Diagonal tightening sequence: ku multi-ebiyungo by’enkwaso (nga flanges), nyweza entangawuuzi mu nsengeka ya diagonal okukakasa okusaasaanyizibwa kw’amaanyi agamu n’okuziyiza okuwuguka kw’okungulu kw’ekiyungo.
Ekiyamba mu kusiiga: Okusiiga omuwendo ogw’ekigero ogw’okusiiga (nga molybdenum disulfide) ku wuzi oba ebitundu ebikwatagana n’entangawuuzi kiyinza okukendeeza ku torque y’okunyweza n’okukendeeza ku kwambala.
Weewale okutabula ebintu: Weewale okukozesa ebintu eby’enjawulo (nga aluminiyamu n’obuuma obukola ebyuma) butereevu okuziyiza okukulukuta kw’amasannyalaze.
iii. Anti-Obukodyo bw'okuzirika .
Okusumululwa kw’entangawuuzi kye kintu ekitera okuvaako ebyuma okulemererwa, era anti-ebipimo ebizimbulukuse byetaagibwa:
Mechanical Anti-Loosening: Kozesa cotter pins, lock washers, oba tandem wire okunyweza nut, esaanira okubeera high-embeera z'okukankana.
Friction Anti-Loosening: Kozesa entangawuuzi bbiri (primary nut + secondary nut) oba spring washers okwongera ku kuziyiza okusikagana.
Enkalakkalira anti-Loosening: Kozesa okuweta mu kifo, okusiba, oba ebizigo (nga loctite) okunyweza entangawuuzi, naye okukakasa okukola okuddaabiriza okuddirira.
Entangawuuzi ez’enjawulo: Eby’okulabirako mulimu Nylon Lock Nuts (ezikwata obuwuzi n’empeta ya nayirooni) oba entangawuuzi za Tang (which self-zisiba n’ensengekera ya eccentric).
iv. Ebiteeso by’okuddaabiriza n’okukyusa .
Okukebera buli kiseera embeera y’okunyweza entangawuuzi kikulu nnyo okuziyiza obubenje:
Okuddamu okunywera buli luvannyuma lwa kiseera: Mu kiseera ky’okukola ebyuma ebisookerwako oba mu mbeera y’okukankana ennyo, entangawuuzi ekulembeddwamu okuddamu okukeberebwa buli luvannyuma lwa kiseera (okugeza, essaawa 50-100).
Okwambala okwekebejja: Singa wuzi, okwambala enkoona y’entangawuuzi, oba okulemererwa okw’okunaaba bizuuliddwa, birina okukyusibwa amangu ddala.
Okwegendereza: Entangawuuzi ezifuuse enfuufu zisobola okunnyika mu mafuta agayingira nga tezinnaba kuggyibwamu n’ekisumuluzo ky’okukuba oba ekisumuluzo kya payipu okwewala okwonoona obuwuzi olw’okukwata amaanyi.
Mu bufunzi
Wadde nga ntono, entangawuuzi kitundu kikulu nnyo mu nkola z’ebyuma. Okukuguka mu kulonda amaloboozi, okuteeka, n’okuziyiza-Obukodyo obutasalako tekikoma ku kulongoosa kwesigika kwa byuma wabula era kigaziya obulamu bwakyo obw’obuweereza. Mu nkozesa entuufu, ennongoosereza ezikyukakyuka zirina okukolebwa nga zisinziira ku mbeera ezenjawulo ez’okukola, era okunywerera ennyo ku mutindo gw’amakolero kulina okugobererwa okukakasa nti buli nut ekola ku mutindo gwayo ogusinga obulungi.
