1. Kugadziriswa kwekuwedzera kubviswa kwemazino

Kuwedzera kwekuregererwa kunowanzokonzerwa nekuwedzera kwekuregererwa pakati pegomba negomba remaoko, saka kusunungurwa kunofanira kudzorerwa mushure mekugadzirisa kusungirirwa kwegomba uye sleeve. Kana kupfeka kwepombi yepombi kusina kukomba, iyo inotakura alloy inogona kuiswa welded pamusoro pemazino, uye yobva yashandurwa maererano nezvinodiwa zvekukodzera. Kana iyo pombi yepombi yakasakara zvakare, iyo sleeve nzira inogamuchirwa kuti igadziriswe. Nzira yacho ndeiyi: kubhowa madziro epombi, uye kushandura semicircular bushing nehupamhi hwe 3 kusvika 4 mm zvichienderana nehukuru hwepombi yepombi nesimbi kana mhangura. Mushure mekunge sleeve yadzikiswa mukati mepombi yepombi, inosungirirwa nechisungo, uye yobva yasungirirwa pamwe chete nehupamhi hwebhushi kumativi ose maviri, uye zvishoma nezvishoma inotonhorera mubhokisi rejecha mushure mekugadzirisa. Pakupedzisira, pombi yepombi inobvongodzwa kusvika kuhukuru hwakaenzana, uye taper yayo uye ovality haisi yakakura kudarika 0.02 mm. Iyo bushing inogona zvakare kusungirirwa ne epoxy resin glue.

2. Kugadziriswa kwekuwedzera giya meshing clearance

Kubviswa kwemazino kune zvishoma pakushanda kwepombi yemafuta, saka kukosha kunobvumirwa kwakakura, dzimwe nguva kusvika ku 1 mm, saka pane zvishoma kugadzirisa. Kana iyo zino regiya risiri rakatsetseka kana riine mabura mushure mekupfeka, riposhe nedombo remafuta. Sezvo mazino epombi akapfekwa kune rumwe rutivi, giya rinogona kushandurwa uye rinoshandiswa kana mazino akareba achipfeka asingapfuuri kukosha kunobvumirwa; kana ichidarika kukosha kunobvumirwa, inofanira kutsiviwa kana kugadziriswa.

3. Kugadziriswa kwekuwedzera kwekupedzisira kubviswa kwechiso

Iyo yekupedzisira kucheneswa kwechiso ine simba guru pazviratidzo zvekushanda zvepombi yemafuta (kumanikidza kwemafuta, huwandu hwemafuta). Kana kuguma kwechiso kubvumidzwa kunodarika mwero, kunofanirwa kugadziriswa. Matanho ekugadzirisa ndeaya anotevera:

(1) Kana pasi pekamuri yepombi yakapfekwa, kukwenenzverwa kunofanira kushandiswa kubvisa madhindi panzvimbo yakasakara.

(2) Kana iyo giya yekupedzisira kumeso uye chifukidziro chepombi chakapfekwa, kana kupfeka kwacho kusiri kwakakomba, nzvimbo yacho inogona kuputirwa nejecha rinoputika uye pasi pachikuva (kana girazi) kubvisa mavanga uye kusaenzana; kana kupfeka kwakakomba uye kupera kwechiso kubviswa kwakakura, kunogona kugadziriswa nekukuya kana kutendeuka kutanga uye ipapo kugaya.

Pakukuya, kureba kwegiya rekupedzisira kumeso pazasi pechiso chekupedzisira kweimba (kureva, zino kupera kubviswa) kunofanirwa kugara kuchitariswa negeji yakadzika kana micrometer. Mushure mekugaya, pombi yepombi inofanira kunge iine mating surface perpendicular kumutsara wepakati wegomba re shaft. Yayo isiri-perpendicularity (kana deflection) kazhinji haina kupfuura 0.1 mm pa100 mm, uye kusaenzana kwenzvimbo yekubatana kazhinji haipfuure 0.02 mm.

4. Kugadziriswa kwekuwedzera kwekuregererwa pakati pemafuta pombi shaft uye kutakura

Sezvo kucheneswa pakati pe shaft uye kutakura kuchiwedzera, iyo yakajairwa meshing yegiya peya ichaparadzwa, uye zino repamusoro rinozokwesha pamusoro pepombi yepombi, ichiparadza hukama hwehukama hwechikamu chimwe nechimwe uye kuderedza mafuta. Kana kubvumidzwa pakati pedhiraivha yekutyaira uye kutakura kwakakurisa, nzira yekugadzirisa saizi inogona kushandiswa kugadzirisa, gomba reshaft rinogona kukwidziridzwa (rinogona kukwidziridzwa ne 0.25 mm, 0.50 mm), uye shaft yekutyaira inogona kukwizwa saizvozvo. (iron plating kana chrome plating), kana inogona kugadziriswa neiyo sleeve nzira (ukobvu hwesleeve hunosvika 15 mm), uye concentricity yemaoko ekumusoro neazasi. inofanira kuchengetedzwa panguva yekuzvitakura. Nokuda kwechikonzero ichi, pamapombi emafuta ane maoko anotakura pavhavha yepombi, zvakanakisisa kuisa chifukidzo chepombi pamuviri wepombi uye kupedza kugadzirisa panguva imwe chete. Iyo taper uye ovality yegomba rinotakura haifaniri kudarika 0.02 mm. Mushure mekugadzirisa, iyo isiri-yakarurama ye shaft haifaniri kudarika 0.05 mm pamusoro pehurefu hwose. Kana iyo clearance pakati pe passive giya shaft uye shaft gomba yakakura kwazvo, iyo nzira iri pamusoro inogona kushandiswawo kugadzirisa. Panyaya yekupfeka kudiki, sezvo iyo passive gear shaft isingafambi, kupfeka kwayo kwakapfeka unilateral, saka shaft inogona kudzvanywa uye kushandurwa 180 ° yobva yatsindirwa mukati kuti ishandiswe (panguva ino, kana iyo static fit kupindira yakaderedzwa. , inogona kugadziriswa ne electroplating). Mushure mekunge shaft yakatsikirirwa mumuviri wepombi, musoro we shaft unofanirwa kunyura mukati mejoint joint surface ne 0.05-0.50 mm. Mushure mekunge gomba reshaft riri pagiya rekupfuura rakapfekwa, rinogadziriswa nenzira ye sleeve. Mushure mekugadzirisa, gomba remafuta ekuzora rinofanira kudonhedzwa maererano nezvinodiwa zvepakutanga.

5. Kugadziriswa kwekuwedzera kweaxial clearance ye shaft inoshanda

Kana iyi clearance ichipfuura kukosha kunobvumidzwa, inogadziriswa nekutarisa kana kuwedzera gasket kumucheto kumashure kwepombi imba. Panguva yekugadzirisa, inofanirwa kuve nechokwadi kuti iyi clearance haisi yakakura kudarika zino kupera kubviswa.
