Uqhagamshelo ifakwe kwikhompyutha. uqhagamshelo ekufakwa - GOST. Nokumelana zithako keyways

uxhulumaniso ifakwe kwikhompyutha - uhlobo lwe iinxalenye ezimbini kwimboniselo befikile gasketed. Kubalulekile. Kulo mzekelo, izinto ezinxulumene element abangabancedani - isitshixo.

enkulu isicelo

bonke lilula kule nkalo. uqhagamshelo esebenzayo ifakwe kwikhompyutha ukuze jointing shaft hub. Oko kukuthi, ukuba ukuthintela ukuba co-ejikelezayo ngexesha transmission torque. Kwakhona, ezi zihlanganisi zisetyenziswa, nangona ngokubanzi, ukuthintela shift ungamalungu moya. Yintoni elandelayo sicinga kuphela icala lokuqala.

uhlobo

uqhagamshelo Key bohlulwa babe ngamaqela ezininzi:

1. Ngokuxhomekeke iqondo ukuhamba. Olu luphawu ebalulekileyo. Kulo mba, ahluka:

• Uxhumano ngesandla. Kulo mzekelo, i ukutyibilika isikhokelo okanye spigot.
• Kunjalo ezibamba.

2. Kwiqela lesibini uthathwa umkhosi aye ngokubambisana. Kukho iindidi ezimbini:

• Langoku. Kule mandla uxhulumaniso eyenziwe ngexesha ibandla. It ikhona ngokwahlukeneyo umsebenzi.
• Unstressed. Kule mandla uxhulumaniso eveliswa kuphela xa umsebenzi.

3. iikhompawundi zihlukaniswe uhlobo izikhonkwane ezisetyenzisiweyo. ezizezi:

• Prismatic.
• Ingxenye.
• Zezindlu.
• Imnyama.
• Tangential.

Ngaphezu koko elichaza uhlobo ngalunye key ngokwahlukeneyo. Okokuqala, nangona kunjalo, kufuneka kuthiwe ukuba la malungu ikakhulu eyenziwe ezikumgangatho ophezulu, zomelele Steel Medium: 45, 50, 55. Le yinyaniso lokwenyaniso. Ukuze kwandiswe ukomelela izikhonkwane, imivalo ngenxa yezandla zabo ngokubanzi phantsi unyango thermal. Oku kuphucula umgangatho wabo.

iqhosha Okhunye

Esi sahluko ngeentlobo ezintathu. Ukuba yahlulwe guides, nezivumelwano zokubambisa yaye ehambayo. Ngenxa yokuba le keyways parallel kunzima endaweni enye kwenye ngenxa kukumelana ngamnye, azikho ezisetyenziswa kwimveliso ngomlinganiselo omkhulu. Le ethile zazo eziphambili. Enye embi kulo mzekelo kukukwazi eziwela ngaphaya ngexesha ukuguga.

iqhosha woodruff

Olu hlobo akanawo neengxaki ezifana kuqala. Ngoko ke, kulula ukuba isicelo kwimveliso. Kodwa kuba luncedo ukuba beqhele ngokubanzi - yinto enkulu cross-candelo kwizikhondo. Akukho lula ukuzifaka phezu isabelo bent ye kwizikhondo zilayishwe.

iqhosha zezindlu

Le yenye iintlobo ezibalulekileyo. Zisetyenziswa ikakhulu eziphelweni kwizikhondo. nokusebenzisa kwabo ifuna ukuba izinto ezidityanisiweyo zahlukile apha lexinene bobuso. Oku kuthintela ukusetyenziswa ngokubanzi olu hlobo amaqhosha kwimveliso ngomlinganiselo omkhulu.

iqhosha tangential

Le ndima iquka iinxalenye ezimbini. Olu hlobo nesinqumka prismatic ene-ebuxande cross-candelo. Misela izibini tangential engundoqo kwi-engile degrees 120-180. Le uncedo lwala maqela yabo ebonakalayo elisebenza ucinezelo kananjalo apha kukho ndlela ilungileyo emseleni ahambelanayo ngokuchasene xi ahambelana ka ntshikilelo. Icala elisezantsi isitshixo enjalo, ungenza bakugqala isixhobo ezintsonkothileyo. Sebenzisa la malungu koomatshini enzima.

alubi iqhosha

kwinqanaba ayihambi ngokusebenzisa amandla frictional.

Pluses amalungu athi:

- uqhagamshelo ifakwe kulo mzekelo uyakwazi ukumelana umthwalo yezihlunu encinane.

- Kwakukho umsebenzi olungileyo phantsi kwempembelelo kwemithwalo variable.

- Akuyomfuneko ukuba asebenzise amalungu ezongezelelweyo eziya ubambe nxamnye intshukumo yezihlunu ye kweendawo.

Outs izitshixo zimi ngolu hlobo lulandelayo:

- Iyamangalisa indlela entsonkothe ngayo disassembly ngexesha ukulungiswa.

- obomeleleyo offset ukusuka embindini hub kuthelekiswa esqwini shaft. Le nkalo.

- Phambi ubude elifutshane ngayo Kit kunokwenzeka ROOTN enkulu kunye runout engeyonxalenye ngaphandle leyo esiqingqiweyo (pulley, nezixhobo).

Nokumelana zithako keyways

Le nkcazo nemaloznachimym. Ukuqinisekisa umgangatho nokumelana ezimiselweyo iikhompawundi keyways. Kubalulekile ukwazi. Uchaza sadubula GOST 2.308-79 "inkqubo Emanyeneyo kwamaxwebhu yoyilo. Qaphela iifom zemizobo nokumelana kunye imiphezulu ". Oku elivumelana obungamaxwebhu isiseko.

I zisephezulu iparameters ebekwe nokumelana indawo ngokuphathelele kubudlelwane zilandelayo: T (IMizekeliso) = 0.6 T (br); T (sim0) = 4.0 T (w).

Apho le Amagama ziquka:

- T (br) - unyamezelwano sadubula ububanzi slot b.

- C (umphunga) - Wathi parameter okukhona.

- T (SIM) - macala ixabiso nokunyamezelana yexabiso ubukhulu.

Ipharamitha ebalwe lwe data kufutshane iinkcazelo eqhelekileyo. Guided oku GOST 24643.

Ukutyala iikhompawundi keyways

Ukuchaneka egxile amalungu ezinikwe ngokukhetha olu khetho. Kubalulekile ukuba siqwalasele. Nokumelana aluchazi iindidi ezintathu iikhompawundi okanye kulotywe. Kodwa lulawulwa nemigangatho. Okulandelayo, khangela uhlobo ngalunye iinkcukacha.

elibona free

Le ukufika akunakusetyenziswa phantsi kweemeko ezinzima amabandla efanayo imithwalo. Isetyenziswa ukuxhumeka ezihambahambayo ezinikezelwe umsebenzi umsebenzi ukukhanya.

uqhagamshelo oluqhelekileyo

Kwachazwa njengento kufanelekile uphazamiseko, akunyanzelekanga ukuba ngokuxabana rhoqo. yokwakha Good iimeko ezahlukeneyo.

ezidibanayo tight

Kwagqitywa amathuba ekufumaneni nokuphazamiseka ezingephi malunga twatse kwi idowel ezichaphazelekayo jointing namacandelo amabini (kwiindawo zokubeka zabo). Indibano lisetyenziswa inani elincinane Ebuyiselwayo imithwalo.

Ukuzimisela ezi zinto

Njengoko sele kukhankanyiwe ngentla apha, ulwimi akuguquki yenziwe ophezulu ezikumgangatho kunye namandla yodidi lwe eliphakathi (55, 50, 45). Ukwandisa amandla wenxalenye ungenanto ukuba aqhele phantsi ukufudumeza unyango, Oku kuphucula umgangatho wabo.

Xa ukuphuhlisa uxhulumaniso ifakwe kwikhompyutha, leyo pre-ukuzoba phezulu, ukuphakama, ububanzi inxalenye usebenzisa GOST esezantsi 2336-7, kuthathelwa ingqalelo sangqa kwizikhondo. Kulo mzekelo, akukho nto kunzima. Ubude ulwimi uthathe kuxhomekeka hub. Thelekisa oku kunye nemimiselo standard efanelekileyo. Ukukhethwa yeqhosha iparameters ezithile zitshekishwe ngokusebenzisa ubalo ebalulekileyo iqhosa lekeyboard lithetha amandla uqhagamshelo. Ekubaleni oku akukho dili enkulu. Umzekelo, imeko amandla kulo mzekelo i fomula ilandelayo:

σsm = F1 / ACM ≤ [σsm].

Apha, F1 - parameter amandla circumferential ukuya pulley (H). AFM ummandla shear (mm²). Eli xabiso kuxhomekeke kule ndlela ilandelayo: (0,94h-T1) lp.

Kulo mzekelo, lp = l-kwiqhosha ubude yokusebenza kunye eziphelweni ajikelezayo. Le parameter ulinganiswa iimilimitha. l - ukuba ifakwe kwikhompyutha ubude ngokupheleleyo.

Imilinganiselo e, h, T1 zizinto ubukhulu eqhelekileyo ngokungqinelana GOST 23360 - 78.

[Σsm] - ngokumisela ukuwa ombane kwenxiwa (N / mm²). Xa usebenzisa isinyithi Kit [σsm] ifunyenwe kuluhlu ethile 55 ... 95 N / mm².

Ukusebenza ubude iqhosha ibalwa ngolu hlobo lulandelayo:

lp = 32 - 6 = 26 mm.

Ukubekwa indawo yokuwela:

ACM = (0.94 · 6 - 3.5) · 26 = 55,64 mm².

Ixabiso F1 bamkele imilinganiselo ifunyenwe. Kulo mzekelo, F1 = 1200 H.

Ngenxa yoko, le ekubaleni ombane rated iya kuba:

σsm = 1200 / 55,64 = 21,56 N / mm².

Oku kubonisa ukuba imeko amandla:

σsm = 21,56> [σsm] (55 ... 95 N / mm²).

Izinto eziluncedo uxhulumaniso iqhosha

Apha kubonakala oku kulandelayo:

• Yila ethembekileyo ixesha elide.
• Kulula ukuba aqoqe ibattery.
• iindleko Low.
• Zibe lula ukuvelisa.

ukushiyeka

Kule nkalo, ndiyabona zilandelayo:

• Keyway buthathaka candelo shaft kunye hub.
• Xa iikhompawundi ezininzi kukho ukungalungelelani. Oko kukuthi, ukubana isalamane esqwini hub shaft yokususwa isiqingatha diametrical.
• Ezimbombeni Inqanaba ombane keyway eliphezulu.
