Kumangitsa ndi anti-kumasula kwa maulalo a ulusi

1. Kuyimitsidwa koyambirira kwa kulumikizana kwa ulusiAsanayambe kugwira ntchito, wonongayo imayang'aniridwa ndi mphamvu yolimbitsa kale.

1. Cholinga cha kumangitsa chisanadze

1) Wonjezerani kuuma kwa mgwirizano

2) Wonjezerani zothina

3) Kupititsa patsogolo luso lokhala lotayirira

Kutsimikiza kwa zotsalira zotsalira: 1) Palibe kusintha kwa katundu wogwira ntchito: FR FR = (0.2 ~ 0.6) 2) Katundu wogwira ntchito amasintha: FR = (0.6 ~ 1) F3) Pali zofunikira zothina: Fp FR = (1.5 ~ 1.8)

$ 10-7 Zipangizo ndi kupsinjika kovomerezeka kwa mabawuti1.Zinthu za boltMabolt amagawidwa malinga ndi makina awo, ndipo muyezo wadziko lonse umanena: Maboti 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8,9.8, 10.9, 12.9Mtedza 4, 5, 6, 8, 9, 12

Tanthauzo la kachidindo ka giredi la bawuti: Nambala ya e yoyamba: imasonyeza malire a mphamvu ya bawuti.1/100 ya izo.σ= nambala yoyamba x 100Nambala yachiwiri: imasonyeza malire a zokolola za bawuti.Kuchulukitsa kakhumi malire amphamvu σ.Sigma.= Nambala yoyamba x nambala yachiwiri x 10Chitsanzo: Kalasi 4.6 boltσρ=4×100-400MPa, σ, =4×6×10-240MPa3.Kupsyinjika kololeka kwa kulumikizana kwa ulusiWonani m'mabuku ophunzirira Matebulo 10-6 ndi 10-7

2. Mafunso owerengera

Chitsulo chopangidwa ndi chitsulo chowongoka pamakiyi ndi cholumikizira chachitsulo, gawo la shaft m'mimba mwake pa giya d = 60mm, hub kutalika L' = 100mm, torque yotumizira T = 5.5 × 105N.mm, kukhudza pang'ono gwirani ntchito, yesetsani kupanga kugwirizana kofunikiraku.Kuthetsa: 1) Dziwani zakuthupi, mtundu ndi kukula kwa fungulo chifukwa chitsulocho chimapangidwa ndi chitsulo chosungunula, zinthu zachinsinsi zimatha kusankhidwa 45 zitsulo, ndipo palibe kayendedwe ka axial pakati pawo. giya ndi kutsinde, kotero A-mtundu wamba lathyathyathya kiyi wasankhidwa.Malinga ndi ekseli m'mimba mwake d=60mm, hub kutalika 100mm, onani Table 10-9,Tengani :b=18mm, h=11mm, L=90mm.
