Ibice bya shaft nikimwe mubice bisanzwe bikunze kugaragara mumashini.Ikoreshwa cyane mugushigikira itumanaho rya zeru

Ibigize, ohereza torque hamwe nu mutwaro.Ibice bya shitingi bizunguruka ibice bifite uburebure burenze umurambararo, kandi mubisanzwe bigizwe nubuso bwa silindrike yo hanze, hejuru ya conic, umwobo wimbere nu mugozi wumutwe wibanze hamwe nubuso bwanyuma.Ukurikije imiterere itandukanye, ibice bya shaft birashobora kugabanywamo ibice bya optique, ibiti byateye intambwe, ibiti bitoboye hamwe na crankshafts.

Igiti gifite uburebure bwa diametre kiri munsi ya 5 cyitwa shaft ngufi, naho abafite igipimo kirenze 20 cyitwa shafts.Imyenda myinshi iri hagati yibi byombi.

Igiti gishyigikiwe nigitereko, kandi igice cyumutwe gihuye nicyuma cyitwa ikinyamakuru.Ibinyamakuru bya Axle nibyo bipimo byinteko ya shafts.Ubusobanuro bwazo hamwe nuburinganire bwubusanzwe birasabwa kuba hejuru.Ibisabwa bya tekiniki muri rusange byateguwe ukurikije imirimo yingenzi nuburyo akazi ka shaft, mubisanzwe ibintu bikurikira:

(1) Ibipimo bifatika.Kugirango umenye aho uruzitiro ruhagaze, ikinyamakuru cyandika gikenera ubusobanuro buhanitse (IT5 ~ IT7).Mubisanzwe, ibipimo byukuri byikinyamakuru cya shaft cyo guteranya ibice byoherejwe ni bike (IT6 ～ IT9).

.Kubireba imbere ninyuma hamwe nibisabwa bisobanutse neza, gutandukana byemewe bigomba gushyirwaho ikimenyetso.

.Mubisanzwe, birakenewe kwemeza ko coaxiality ibisabwa byikinyamakuru cya shaft cyibice byakusanyirijwe hamwe kubinyamakuru bifasha ikinyamakuru, bitabaye ibyo bizagira ingaruka ku ihererekanyabubasha ry’ibice byoherejwe (ibyuma, nibindi) kandi bitange urusaku.Kubisanzwe bisanzwe, umurongo wa radiyo uhuza igice cya shaft uhuza ikinyamakuru gishyigikira muri rusange 0.01 ～ 0.03mm, naho ibiti bisobanutse neza (nkibiti nyamukuru) mubisanzwe ni 0.001 ～ 0.005mm.

Ibikoresho n'ibikoresho by'ibice byafunitse
.Kuri shaft ifite itandukaniro rito muri diameter yo hanze, ibikoresho byumurongo bikoreshwa muri rusange;kubitambambuga byintambwe cyangwa ibiti byingenzi bifite diameter nini yo hanze, kwibagirwa akenshi bikoreshwa, bibika ibikoresho kandi bigabanya akazi ko gutunganya.Kunoza imiterere yubukanishi.

Ukurikije umunzani utanga umusaruro, hari ubwoko bubiri bwuburyo bwo guhimba ubusa: guhimba kubuntu no gupfa guhimba.Guhimbira ubuntu ahanini bikoreshwa mubikorwa bito n'ibiciriritse, kandi gupfa gukoreshwa bikoreshwa mubikorwa byinshi.

Ibyuma 45 nibikoresho bisanzwe kubice bya shaft.Nibihendutse kandi nyuma yo kuzimya no gutwarwa (cyangwa nibisanzwe), irashobora kubona imikorere myiza yo gukata, kandi irashobora kubona ibikoresho byubukorikori byuzuye nkimbaraga zo hejuru no gukomera.Nyuma yo kuzimya, gukomera hejuru birashobora kugera kuri 45 ～ 52HRC.

Gukoresha ibyuma byubaka nka 40Cr birakwiriye kubice bya shaft bifite icyerekezo giciriritse kandi cyihuta.Nyuma yo kuzimya no gutuza no kuzimya, ubu bwoko bwicyuma bufite imiterere yubukanishi bwiza.

Kwitwaza ibyuma GCr15 nicyuma cyimpeshyi 65Mn, nyuma yo kuzimya no gushyuha no kuzimya inshuro nyinshi kuzimya, gukomera hejuru birashobora kugera kuri 50-58HRC, kandi bifite imbaraga zo kurwanya umunaniro mwinshi no kwihanganira kwambara neza, bishobora gukoreshwa mugukora ibiti byuzuye neza.

Igikoresho nyamukuru cyibikoresho byimashini isobanutse (nk'uruziga rwo gusya uruziga rwa gride, spindle ya mashini irambirana) irashobora guhitamo ibyuma bya nitride 38CrMoAIA.Nyuma yo kuzimya no gushyushya no hejuru ya nitriding, iki cyuma ntigishobora kubona gusa hejuru yubutaka bwo hejuru, ariko kandi kigumana intangiriro yoroshye, bityo kigira ingaruka nziza zo kurwanya no gukomera.Ugereranije nicyuma cya karubone kandi gikomeye, gifite ibiranga uburyo bwo kuvura ubushyuhe buto no gukomera cyane.

No 45 ibyuma bikoreshwa cyane mubikorwa byo gukora imashini, kandi imiterere yubukanishi bwibyuma nibyiza cyane.Ariko iyi nicyuma giciriritse giciriritse, kandi imikorere yacyo yo kuzimya ntabwo ari nziza.No 45 ibyuma birashobora kuzimya HRC42 ~ 46.Kubwibyo, niba hakenewe ubukana bwubuso hamwe nubushobozi bwikirenga bwa 45 # ibyuma byifuzwa, ubuso bwa 45 # ibyuma burazimya (kuzimya inshuro nyinshi cyangwa kuzimya mu buryo butaziguye), kugirango uburinganire bukenewe bushobore kuboneka.

Icyitonderwa: No 45 ibyuma bifite diameter ya 8-12mm bikunda gucika mugihe cyo kuzimya, nikibazo gikomeye.Ingamba ziriho ubu ni uguhindura byihuse icyitegererezo mumazi mugihe cyo kuzimya, cyangwa gukonjesha amavuta kugirango wirinde gucika.

Kuzunguruka murwego rwo gusana ibumba
Moderi yo gusudira ikoreshwa kuri No 45 ibyuma ni: CMC-E45

Nibikoresho byonyine byo gusudira ibyuma biciriritse biciriritse bifite imiterere myiza yo guhuza, bikwiranye nicyuma gikonjesha ikirere, ibyuma bikozwe: nka ICD5, 7CrSiMnMoV… nibindi. ibice birambuye, kandi birashobora no gukoreshwa mubuso bukomeye.

Mubyongeyeho, hari ibintu bimwe na bimwe ugomba kwitondera mugihe ukoresha:

1. Mbere yo kubaka ahantu hatose, electrode igomba gukama kuri 150-200 ° C muminota 30-50.

2. Mubisanzwe ushushe hejuru ya 200 ° C, gukonjesha umwuka nyuma yo gusudira, kugabanya imihangayiko nibyiza niba bishoboka.

3. Mugihe hasabwa gusudira cyane gusudira, koresha CMC-E30N nka primer kugirango ubone ingaruka nziza yo gusudira.
