1. Kugara kusungirirwa kwetambo yekubatanidzaKusati kwaitwa kwemutoro wekushanda, screw inoiswa pasi pechiito che pre-tightening force.
1. Chinangwa chekutanga kuomesa
1) Wedzera kuoma kwekubatana
2) Wedzera tightness
3) Kuvandudza kugona kuramba wakasununguka
Kutsunga kwezvakasara preload: 1) Hapana shanduko mumutoro wekushanda: FR FR = (0.2 ~ 0.6) 2) Mutoro wekushanda unoshanduka: FR = (0.6 ~ 1) F3) Pane zvinodiwa zvakasimba: Fp FR = (1.5 ~ 1.8)
$10-7 Zvishandiso uye zvinotenderwa kushushikana kwemabhaudhi1.Bolt materialMabhoti akaiswa muzvikamu maererano nemaitiro awo emuchina, uye chiyero chenyika chinotemerwa:Bolts 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8,9.8, 10.9, 12.9Nuts 4, 5, 6, 8, 9, 12

2. Mibvunzo yekuverenga
Simbi yakakandwa yakatwasuka zino cylindrical giya kuburikidza nekiyi uye yesimbi shaft yekubatanidza, iyo shaft chikamu dhayamita pagiya d=60mm, hub kureba L'=100mm, iyo inofambiswa torque T=5.5×105N.mm, kashoma mu shanda, edza kugadzira iyi key connection.Solution: 1) Sarudza zvinhu, rudzi uye ukuru hwekiyi nokuti hubhu yakagadzirwa nesimbi yakakandwa, zvinhu zvekiyi zvinogona kusarudzwa 45 simbi, uye hapana axial kufamba pakati. giya uye shaft, saka A-mhando yakajairika flat kiyi inosarudzwa.Maererano neakisi dhayamita d=60mm, hub kureba 100mm, ona Tafura 10-9,Tora :b=18mm, h=11mm, L=90mm.
