1. Kugadzirisa nzira yemumwe wezino kukuvara kwegiya
(1) Adhesive isa zino nzira. Chekutanga chinodiwa kubvisa zino rakatyoka, uye kugadziridzwa kuita dovetail groove pamudzi wezino, uchishandisa chinhu chimwe chete kugadzira chidimbu chezino chitsva kuita dovetailed, shandira pamwe neiyo dovetail groove yegiya pairi, chengeta iyo 0.1 ~ 0.2 mm kubvumidzwa, uye gadzira machining matsva. zino, iva nemvumo yekupedzisa, mushure mekubatana kwakasimba kwemazino matsva uye nzvimbo dzinotsvedza, gadzira template yemazino egiya, uye wozopedzisa mazino matsva, Kusvikira sampuli yabatana nemazino. Iyi nzira yakanakira giya ine urombo welding performance.
(2) Welding isa zino nzira. Iyi nzira inokodzera giya rine yakanaka welding performance, uye kugadzirisa kwayo kwakafanana nenzira yekubatanidza kupinza mazino.
(3) Yakamisikidzwa murwi pamusoro penzira. Muchibooreso chezino chakatyoka, chinomisikidzwa pamirwi yebhaudhi imwe chete kana kupfuura, nenzira yepamusoro pazino rakatyoka ichipfuura zino idzva, ***, inogadziriswa zino rimwechete sedzino rekutanga.
2. Gear fracture kugadzirisa
Muchivharo chekufambisa chevhavha, kana giya rakaputsika, rinofanira kutsiviwa nechikamu chitsva. Kana pasina chikamu chitsva chenguva pfupi, chinogona kugadziriswa maererano nenzira yakaratidzwa mumufananidzo 7-10.
Gear fracture kugadzirisa (1) Kutyoka kwegiya rakatyoka rinogadziriswa mugororo, uye ipapo giya rakatyoka rinopinzwa mugiya rekudzoreredza, uye nzvimbo yemoto inogadziriswa.
(2) iyo clamping groove yendiro yekusimbisa inogadzirwa pazviso zviviri zvekupedzisira zvegiya. Iyo yekunze dhayamita ye groove inofanira kuva 5mm idiki pane dhayamita yemudzi wedenderedzwa, uye dhayamita yemukati idiki zvishoma pane yemukati dhayamita yerimu. Kudzika kwegorofu kunoenderana nekukora kwegiya, kazhinji pakati pe3 ne6mm.
(3) Saizi yegirovha yekunamatira ichakunda, uye mota ichaita zvindori zviviri zvekusimbisa. Izvo zvindori zviviri zvekusimbisa zvichave zvakanyungudutswa uye zvakagadziriswa mu clamping groove yezviso zviviri zvekupedzisira.
Chiyero chekushandisa uye tekinoroji zvinodiwa zvemagetsi chiteshi mavharuvhu (1) Iyi chiyero inotsanangura kudzvanywa uye tembiricha giredhi yemagetsi chiteshi mavharuvhu uye izvo zvinodikanwa zvezvinhu, dhizaini, kuongorora, kumaka, kurongedza, kuchengetedza, chekufambisa, magwaro ekutumira, nezvimwe, uye inopa gwara rekuraira zvinodiwa. Valve zvinhu zvinofanirwa kusarudzwa zvinoenderana nemamiriro ekushandisa uye zvinodiwa zvekugadzira; Mabhoti, nzungu uye zvimwe zvinhu zvinosimbisa zvinofanirwa kusarudzwa maererano nekushandiswa kwekumanikidza uye tembiricha. Paunosarudza zvinhu zvekutakura zvikamu zvehombodo, kupisa kwakanyanya kwekushanda kunofanira kutsanangurwa muAppendix C. Iyi chiyero inopa yakaderera kana zvishoma zvinodiwa zvekugadzira valve, asi haisi iyo yakakwana yekugadzira zvinodiwa.
