NaLindiili P 65: uphawulo, inkcazelo, ubukhulu

Isiseko se kaloliwe womnatha up yimiqolo Russian F 65 - uyilo yomgama kabini T-candelo, ezo ngenxa entsa imithwalo kumlibo ukuziqengqa, "inkqubo" zabo elastic ukudluliselwa olulandela inkxaso - sleepers. Iinkcukacha zezi "imiqadi zentsimbi" kulawulwa GOST 8161-75. Useka kubume nobungakanani yimiqolo ungacimi kwaye unquenched kunye kaloliwe abezindaba uhlobo R65.

Komzila 65 F

Naziphi na komzila zenzelwe ukusombulula ezininzi iingxaki. Okokuqala, bebona nokudlulisa nomthwalo kuloliwe. Kuyimfuneko ukulondoloza bokuphila zombini subgrade kunye namavili. Okwesibini, banikela ulwalathiso ukuhamba kaloliwe. Kwaye ekugqibeleni, ukuba ukudala iqonga kunye ezilu- ukuya ceca yamavili. Iinkcukacha kumphezulu elements ukusebenza ezimbalwa iisentimitha (3-5, kuxhomekeke kudidi lwe indlela). Umda kwezakhiwo yomgama emelwe ebanzi ngokufanelekileyo. Ngoko ke, lo yimiqolo R 65, kwakunye R50, R75, esetyenziselwa engamzondi inkokheli umkhondo iqela jointless kunye gauge ebanzi. Kananjalo zisetyenziswa xa kudalwa turnouts. Kwimeko yokugqibela, iimveliso linear umfanekiso lungiswa (RK65).

enezinto ngololiwe

Komzila R65, kwakunye naziphi na ezinye iintlobo, akanako ngokuba yesiqhelo I-msebe. Iingcali balatha iinxalenye zayo kuyilo multiple olunemiqathango:

1. Intloko - fomu yayo zinika ukubambelela ekhuselekileyo r amavili kunye kaloliwe ngokwayo.
2. Intamo - ukuxhathisa imithwalo ukugotywa, kwaye edlulisela ukuba inkxaso isakhiwo kwingoma.
3. Sole - inikezela uzinzo kubume iphela yomgama isasaze ntshikilelo ngaphesheya kumphezulu olele. Luquka ekunene nasekhohlo ebuhlanti.

Ngaphezu koko, kwiindawo ezimbini ezahlulwe sisithuba kaloliwe elahliweyo ecaleni entanyeni asekhohlo nasekunene kwaye ukuhlala isithuba ukusuka ungqameko olungezantsi intloko ayinakuthi midsole. Oku njalo-ebizwa sinus ekhohlo nasekunene. Bona amalungiselelo ezifakelwa imnyama, apho abayibambe yimiqolo 65 R phakathi kwindlela kwezinye iindawo.

zobukhulu rail P65

Bambalwa wazibuza ukuba kutheni kaloliwe P 65 nje ifomu leyo. Ngelo xesha, radius ngalinye zokuphuma amagophe ezinyongeni, indawo ethe tyaba namathambeka abakhethiweyo empirically okanye ubalo ukudala iimeko kangangoko ukuba intsebenziswano kunye kaloliwe. Inkoliso yethu yazi ukuba ubunzima kaloliwe P 65 ilingana no-65 kg, nto leyo eneneni ayilunganga. mass obububo ngokweemitha 64,72 kg nganye. Abanye iinketho kuba nezi ntsingiselo zilandelayo:

• radius die (R500) eqinisekisa egxile wolayisho, ngamanye imikhosi ungqamane esqwini longitudinal le asi wheel kaloliwe;
• R80 kudala inguqu kwamagingxi-R15, nto leyo idala uxhumane olusondeleyo ivili ihambe;
• icala intloko 1:20 ingqamana kwithambeka esisangqa kwevili oko kuyimfuneko ukuze neza kunye umqhele lwevili;
• radius R3 usondelisa ukuba usiko lwe entloko kwenziwa ukuphelisa bemfuyo uxinzelelo;
• radii yexeshana R15 kunye R370 kuqaliswa ukuze kuqinisekiswe ukuxuba kummandla intloko-entanyeni nokuphelisa yombane eziyingozi;
• R400 utshintsho radius esisekweni wesibeleko iyafuneka ukuze transfer umthwalo kwamagingxi yedwa;
• amacala ubuso ephezulu kunye esezantsi inxalenye yintloko ezifanayo (1: 4), kufuneka ukuba ufake kwamagqabi nesinqumka-ezimile, yaye kwangaxeshanye akhonze njengoko spacers.

Imihla abakhuselekanga imithwalo emikhulu kaloliwe 65. P ubunzima bayo kushishino Russian ayikwazi phantsi. Kodwa ukuba akuyi kuba uyilo okhethekileyo, akaba nako ukumelana msebenzi, ukuba lokoluka ngokukhawuleza yaye kwakufuneka itshintshwe.

steel kaloliwe

Zonke komzila kaloliwe (65 R, RK65, P75, P50) zenziwa kuphela ye ngensimbi kaloliwe. It has a amandla oluphezulu ukugobeka, ngokuba lukhuni banxibe ukuxhathisa, nto leyo kuzuzwa ezinomthamo eliphezulu carbon (0.82%) kunye dopants ungeza - manganese, vanadium, zirconium, lesilicon, titanium. M76VT - uhlobo olusisiseko ngentsimbi, ezisetyenziswa xa kusenziwa imivumbo zikaloliwe. Kuxhomekeka kwindlela yokulungiselela, oko kusenokuba yokuqala (fusible kuphela emlilweni open-eziko) okanye iqela lesibini. Cast okanye ngaplastiki "ihagu" udlulela inyathelo esimbaxa unyango ubushushu multistage. Ubukhulu becala ngenxa yesi sizathu kwi kaloliwe i R 65 ixabiso ukuze eliphezulu - amawaka 50 engange ngetoni nganye ..
