Indlela yokumisa ukukhutjhwa kwentambo yesikrufu se-Lag nokuhlukaniswa kwesigodo esiqinileko ekuhlelweni kwesakhiwo
Nangabe wake waphenduka ubudisi isikrufu se-lag ibe ziinkuni eziqinileko ezomisiweko. Kungenzeka bona ukugandeleleka kuphelelwe yi-torque ephakathi. Kungenzeka kube nokuqhekeka okubukhali, kwaphela ukuthola bona iinkuni zihlukene. Nanyana ngubani osebenza ekwakhiweni kwamaplanka amakhulu ulahlekelwa khulu ngebanga leendaba ezimbili.
Ukukhutjhwa kwentambo kutjhiya isikulufu sijikeleza kungasizi ngalitho emgodini omkhulu khulu, okunikela amandla we-clamp. Ukuhlukaniswa kweengodo kwenza bona ukuhlobana kwesakhiwo kube yinto yokuzilungisa, kanengi kutlhoga ama-joist ahlanganisiweko nofana ama-bracket amakhulu khulu ukobana adlule ekuhlolweni. Iindaba lezi akusiyo into encani kumafreyimu amakhulu wamathafa nofana izakhiwo zamaplanka ezinezitezi ezinengi: azipheleli ekusetjenzisweni kabutjha okukhulu nokunyuka kweendleko zezinto, kodwana kesinye isikhathi zingabangela bona ukuhlanganiswa okuthwala umthwalo kuhluleke ekuhlolweni kokukhipha.
Umqondo ongakalungi ovamileko kukuthi iinkuni ziqinile khulu nofana umtjhayeli une-torque enengi khulu. Emafreyimini amakhulu wamathafa nofana izakhiwo zamapulangwe ezinezitezi ezinengi, iindaba lezi akusiyo into encani: azipheleli ekusebenzeni kabutjha okukhulu nokunyuka kweendleko zezinto, kodwana kesinye isikhathi zingabangela nokuthi ukuxhumana okuthwala umthwalo kuhluleke ekuhlolweni kokukhipha.
Kubayini iinkulufu ezijayelekileko ze-Lag zihlukanisa begodu zihlukanise iinkuni eziqinileko?
Ukugcwala khulu kwephitjhi yentambo ejwayelekileko kubangela ukuhlukana kweengodo.
Ngokuya ngomklamo wamabhawudo womtjhini, iinkulufu ezijayelekileko ze-lag zivamise ukuba ne-pitch yentambo ehle khulu. Eenkuni eziqinileko eziqinileko ezifana ne-oki, i-ipe, nofana i-southern yellow pine, imicu ehlukaniswe kuhle angeze yakghona ukususa imicu yeenkuni. Kunokobana usike indlela ehlanzekileko, isikulufu sicindezela iinkuni ngehlangothini. Njengoba umfutho ukhuphuka, iinthoro ziyadela, okurholela ekutheni kube nokuhlukana emgodini we-pilot kanye nomphetho.
Ngesikhathi esifanako, ithuli leplanka elipakiweko kanye nemicu ivaleleka hlangana neentambo, okwenza bona kube nokutjhayisana okukhulu. Umsebenzisi usebenzisa i-torque enengi njengombana umtjhayeli azabalaza ukujika, begodu imicu ikhupha umgodi nofana ikhanda lesikrufu liyasika.
Ukwelatjhwa ngokutjhisa kusetjenziswe kumbi ukukhutjhwa kwentambo.
Ubulukhuni bezikulufu ze-lag buthembele ngokupheleleko ebuchwephesheni bokuhlanza ngokutjhisa. Iinkulufu ezijayelekileko ezibizako zinemiraro emibili emikhulu yokulawula ukuqina: ukuqina okukhulu kokucima kwenza umzimba wesikrufu ube budisi begodu ube budisi, okuvimbela amazinyo wentambo bona angaguquki kancani ngesikhathi sokuqiniswa kwe-torque ephezulu. Lokhu kuphumela ekugugeni okunqophileko nokutjhelela kwemicu yamaplanka, okwenza bona intambo ikhutjhwe. Ngakelinye ihlangothi, iinkulufu ezingafuthumeleko, eziqinileko, azinamandla aneleko begodu amazinyo wentambo ayakhubazeka begodu abhidlike ngaphasi komthwalo, alahlekelwe mamandla wokukhiya.
Isikrufu se-lag eyakhiwe kuhle sisebenzisa umgogodla oqinileko onendawo eqinileko ukulinganisa ukugcinwa kwentambo nokugeleza kwe-chip.
Isakhiwo esingakalungi se-shank sidosela ekuhlulekeni kwesakhiwo sesikhathi eside.
