Isilumkiso esiBalulekileyo: Esi sisicatshulwa soovimba bembali, hayi ubalo lwangoku lomatshini, uvavanyo lomngcipheko okanye incwadi yokusebenza. Inani leenguqu, istroke, ukufuduswa, amandla, i-coefficients kunye namaxabiso etheyibhile kufuneka ahlolwe ngokwemigaqo esebenzayo, amaxwebhu omenzi kunye neemeko ezithile zokuvelisa.
Lo mbhalo asingomatshini unikezelo okanye uxwebhu lwenkonzo ye-Savo Kusić. Unikezelo lwangoku lugxile kwiifestile, iingcango kunye nezisombululo ezinxulumeneyo.
Inani leenguqu kunye nobungakanani bestroke
Inani le-revolutions ye-shaft inquma ukuveliswa kwesango. Ukuphakama kwenani leenguqu, ukuphakama kwemveliso kwisayizi efanayo ye-stroke yesango. Nangona kunjalo, ngaphandle kokubala kwangaphambili, inani le-revolutions ye-shaft akufanele linyuswe, njengoko oku kukhokelela ekunyuseni okukhulu kwi-inertial forces, enokubangela ukungaphumeleli kwesango. Inani lee-revolutions of the shaft ranges ukusuka ku-200 ukuya ku-350 ngomzuzu kubagcini bamasango banamhlanje. Isakhelo esineesarha ezixineneyo sinyuka sinyuka kwaye ngale ndlela izigodo ziyasikwa. Umgama ohanjwayo isakhelo sesango ukusuka kweyona ndawo isezantsi ukuya kwephezulu ubizwa ngokuba yi-gatter stroke size.
Ubungakanani be-stroke buchaphazela imveliso yomgcini-sango. Ngokunyuka kwe-stroke, kunye nenani elifanayo leenguqu, ukuveliswa kwesango kuyanda. Ubungakanani bestroke bunokwandiswa kuphela ukuba ubalo lwenziwe kwangaphambili.
Inyathelo - ukufuduswa kukuhamba kwezigodo ngexesha elinye elipheleleyo le-shaft yesango. Ubungakanani benyathelo ngamandla emoto yokuqhuba inokumiselwa ngefomula:
Ukufuduswa kweLog kunye neePatheni zeMbali
Δ = 140N / Σn mm apho Δ ilinyathelo lelogi okanye umqadi ngexesha elinye elipheleleyo lokujika kwesango lesango, mm; N - amandla emoto k x s; Σ h - isamba sokuphakama kweesikethi phakathi kobude belogi; h - isibalo seendawo eziphakamileyo zokusikwa phakathi kobude belogi, m; n - inani leenguqu ze-shaft yesango, min.
Isixa sobude bokusikeka singabalwa ngokwefomula Σ h = α x dsr x z, apho α i-coefficient, ebonisa ubude obuphakathi bokusikwa kwaye kuthathwa 0,65 - 0,80 xa usika izigodo. Xa umqadi unqunyulwa, lo mlinganiso ulingana nobunye; dsr- idayamitha embindini welog; z - inani leesarha eziqiniweyo kwisakhelo.
Ukusika i-oki, ubungakanani be-offset 60%, i-larch - 85%, i-beech - 70%, i-birch - 80% ukusuka kwi-offsets yepine kunye nespruce enikwe kwitheyibhile 1.
