1. Ukuqiniswa kwangaphambili kokuxhumeka kwentamboNgaphambi kokwenza umsebenzi womthwalo, isikulufu singaphansi kwesenzo samandla okuqinisa ngaphambilini.
1. Inhloso yokuqinisa ngaphambili
1) Khulisa ukuqina kokuxhumana
2) Khulisa ukuqina
3) Thuthukisa ikhono lokuzigcina ukhululekile
Ukunqunywa kokulayisha kuqala okuyinsalela:1) Alukho ushintsho kumthwalo wokusebenza:FR FR= (0.2~0.6)2) Umthwalo osebenzayo uyashintsha:FR= (0.6~1) F3) Kunezidingo zokuqina:Fp FR=(1.5~1.8)
$10-7 Izinto kanye nezingcindezi ezivumelekile zamabhawodi1.Impahla yebholtAmabhothi ahlukaniswa ngokwezakhiwo zawo zokuwenza, futhi izinga likazwelonke liyasho:Amabhawodi 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8,9.8, 10.9, 12.9Amantongomane 4, 5, 6, 8, 9, 1,2
2. Incazelo yekhodi yebanga lokusebenza kwebhawodi:Inombolo engu-e yokuqala: ikhombisa umkhawulo wamandla aqinile wento yebhawodi.1/100 yalokho.σ= idijithi yokuqala x 100Idijithi yesibili: ibonisa umkhawulo wesivuno sento yebhawodi.Iphinda izikhathi eziyishumi umkhawulo wamandla σ.Sigma.= Idijithi yokuqala x idijithi yesibili x 10Isibonelo: Ikilasi 4.6 boltσρ=4×100-400MPa, σ, =4×6×10-240MPa3.Ukucindezelwa okuvumelekile kokuxhumana okucushiweBheka incwadi yokufunda Amathebula 10-6 kanye no-10-7
2. Imibuzo yokubala
Igiya lensimbi eliqondile lezinyo eliyisilinda ngokhiye noxhumo lweshaft yensimbi, ububanzi besigaba seshaft egiyeni d=60mm, ubude behabhu L'=100mm, itorque T=5.5×105N.mm, umthelela omncane sebenza, zama ukuklama lolu xhumano oluyisihluthulelo.Isixazululo: 1) Nquma impahla, uhlobo nosayizi wesihluthulelo ngoba ihabhu lenziwe ngensimbi ecijile, impahla yesihluthulelo ingakhethwa insimbi engu-45, futhi akukho ukunyakaza kwe-axial phakathi igiya ne-shaft, ngakho-ke kukhethwa ukhiye oyisicaba ovamile wohlobo luka-A.Ngokobubanzi be-axle d=60mm, ubude behabhu 100mm, bheka Ithebula 10-9,Thatha :b=18mm, h=11mm, L=90mm.
