Nadiifinta axial ee shafka cirfiidka waxaa sidoo kale loo yaqaan nadiifinta dhamaadka ee shafka. Hawlgalka mishiinka, haddii farqiga u yahay mid aad u yar, qaybaha ayaa ku xayiran sababtoo ah ballaarinta kulaylka; haddii farqiga u weyn yahay, crankshaft waxay keeni doontaa dhaqdhaqaaqa axial, dedejiso xirashada ee dhululubada, oo saameeyaa hawlgalka caadiga ah ee wajiga waalka iyo xajin. Marka mishiinka dib loo habeeyo, cabbirka farqigan waa in la hubiyaa oo la hagaajiyaa ilaa uu ku habboon yahay.

Cabbirka nadiifinta shafka waxa ka mid ah cabbiraadda nadiifinta dhididka iyo cabbiraadda nadiifinta shucaaca.

(1) Cabbirka nadiifinta axial ee shafka. Dhumucda saxanka riixitaanka ee ku yaal dhamaadka dambe ee shafka ayaa go'aaminaya nadiifinta dhidibka ee shafka. Markaad cabbirayso, dhig tusaha garaaca dhinaca hore ee mishiinka matoorka, garaac shafka si aad dib ugu celiso booska xadka, ka dibna ku toosi tusiyaha garaacista eber; ka dibna u sii dhaqaaq shaft-xadhka ilaa booska xadka, ka dibna tusaha garaaca Tusiyaha waa nadiifinta axial ee shafka. Waxa kale oo lagu qiyaasi karaa cabbirka dareenka; Isticmaal laba kaashawiito si aad u kala geliso inta u dhaxaysa daboolka muhiimka ah ee gaarka ah iyo cududda muruqa ee u dhiganta, iyo ka dib markaad u soo jiido shafka hore ama dib ugu celiso booska xadka, geli cabbirka cabbirka xajmiga toddobaad oo lagu cabbiray inta u dhaxaysa dusha la riixayo iyo dusha sare ee shafka. , farqigani waa farqiga axial ee shafka. Marka loo eego qawaaniinta asalka ah ee warshadda, halbeegga nadiifinta axial ee mashiinka gawaarida ee gaarigan waa 0.105-0.308mm, xadka xirashaduna waa 0.38mm.

(2) Cabbirka nadiifinta shucaaca ee xajinta weyn. Nadiifinta u dhaxaysa joornaalka ugu weyn ee crankshaft iyo xajinta ugu weyn waa nadiifinta shucaaca. Markaad cabbirayso, geli cabbirka fiilada balaastikada ah (cagta farqiga balaastikada ah) inta u dhaxaysa joornaalka ugu weyn iyo meesha ugu muhiimsan, kana taxaddar inaadan beddesho shafka si aad uga ilaaliso farqiga inuu isbeddelo inta lagu jiro wareegga iyo qaniinyada cabbirka farqiga. Waa in fiiro gaar ah loo yeeshaa saamaynta ay ku leedahay tayada shaftirka ee nadiifinta.
