Kunezinhlobo ezimbili zeIndandatho yokubulalaUkulimala, munye umonakalo womjaho, kanti enye yizinyo eliphukile. Umonakalo womjaho we-Akhawunti ka-Akhawunti ngaphezulu kwama-98%, ngakho-ke ikhwalithi yomjaho iyisici esibalulekile esithinta impilo yeIndandatho yokubulala. Phakathi kwazo, ubulukhuni bezampisi, ukujula okuqinile, ububanzi be-rackay curvature radius kanye ne-angle yokuxhumana yizici ezine ezibaluleke kakhulu ezithinta ikhwalithi yomjaho.
1. Ubulukhuni bomjaho
Ubunzima obucimayo kweIndandatho yokubulalaI-Raceway inomthelela omkhulu emthwalweni wayo okalwe Uma umthwalo olinganiselwe olinganiselwe u-1 ku-55hrc, ubudlelwane obuhambisanayo phakathi komthwalo olinganiselwe olinganiselwe we-harting kanye nobulukhuni bomjalo womjaho ungokulandelayo:
| Ubulukhuni be-Raceness HRC | 60 | 59 | 58 | 57 | 56 | 55 | 53 | 50 |
| Umthwalo we-static okalwe | 1.53 | 1.39 | 1.29 | 1.16 | I-1.05 | 1 | 0.82 | I-0.58 |
Le khasiukuthwala okubuthayokusuka ku-xzwdukuthwala okubuthayoI-Company Race Wayness ingu-55hrc ~ 62HRC.
2.Ukujula kwesendlalelo esiqinile somjaho
Ukujula okudingekayo kwesendlalelo esilukhuni yisiqinisekiso sokuthiIndandatho yokubulalaI-Raceway ayishintshi. Laphoukuthwala okubuthayoIthwala umthwalo wangaphandle, ibhola lensimbi kanye nokushintshwa komjaho kusuka ekuxhumaneni kwamaphoyinti kuya koxhumana nabo, futhi indawo yokuxhumana iyindawo ebonakalayo. Ngaphezu kwengcindezi ecindezelayo, umjaho futhi uncike ekucindezelekeni kwe-shear, futhi ukucindezelwa okukhulu kakhulu kwe-shear kwenzeka ekujuleni kwe-0.47a (i-axis enkulu ye-axis ye-ellipse) ngaphansi kwesilinganiso sebhola lensimbi esikhundleni sobubanzi beIndandatho yokubulala, kanye nenani eliphansi eliqinisekisiwe linikezwa ezingeni. Umthwalo we-tuli olinganiselwe olinganiselwe ukuhambisana ulingana nokujula kwesendlalelo eqinile H0.908. Uma ukujula kwesendlalelo okuqinile okudingekayo ukuze ube ngu-4mm kuqedwe kuphela ku-2,5mm, i-tuling tatic C izoncishiswa kusuka ku-1 kuye ku-0.65, amathuba okulimala kuukuthwala okubuthayoNgenxa yokukhonkotha ukugcwala kuzokhuphuka kakhulu.
Ngokwesibonelo,ukuthwala okubuthayoI-Raceway Layer Depple-1013.35.1250 Raceway ngu-≥ 3.5mm.
3.Imisebe ye-curvature yomjaho
I-Rackay Curvature Radius ibhekisela kwimisebe ye-curvature yomjaho we-racical esigabeni esithe mpo. Isilinganiso se-radio yomjaho womjaho eya emsakazweni webhola lensimbi futhi sithinta kakhulu umthwalo olinganiselwe we-static kanye nokuphila kokukhathala kweIndandatho yokubulala. Lapho t = 1.04, umthwalo olinganiselwe we-static kanye nempilo yokukhathala ungo-1, kanye nobudlelwano obuhambisanayo phakathi komthwalo olinganiselwe we-tuli kanye nokuphila kokukhathala kweIndandatho yokubulalafuthi t ngokulandelayo.
| Isilinganiso se-curvature | I-1.04 | I-1.06 | I-1.08 | 1.10 |
| Umthwalo we-static okalwe | 1 | 0.82 | 0.72 | 0.65 |
| Impilo yokukhathala | 1 | 0.59 | 0.43 | 0.33 |
Kungabonakala etafuleni elingenhla ukuthi likhudlwana isilinganiso seRadius, lehlise umthwalo olinganiselwe olinganiselwe kanye nemfushane yempilo yenkonzo.
I-4.Raceway Anglele Angle
I-angle yokuxhumana isho i-angle phakathi komugqa oxhumanisa iphuzu lokuxhumana nebhola lensimbi emjahweni kanye nesikhungo sebhola lensimbi nesigaba se-radial (indiza evundlile) yeukuthwala okubuthayo. Umthwalo we-static okalweIndandatho yokubulalailingana ngokuqondile esonweni, futhi i-angle yokuqala yokuxhumana imvamisa ingu-45 °. Laphoukuthwala okubuthayoInegebe, i-angle yangempela yokuxhumana inkulu kune-angle yokuqala yokuxhumana. Uma likhudlwana igebe, likhudlwana i-angle yangempela yokuxhumana. Ngaphakathi kwebanga legebe elichazwe ngokwejwayelekile, lizokwanda ngo-2 ° ~ 10 ~ 10, okungukuthi, i-angle yangempela yokuxhumana izofika ngo-47 ° ~ 55 °, okuwukushintsha okuhle kwekhono lokuthwala. Kepha uma i-angle yokuqala yokuxhumana negebe likhulu, i-angle yangempela yokuxhumana izodlula i-60 °. Njengoba umjaho womjaho ugqoke, igebe lizophinda likhuphuke futhi i-angle yokuxhumana yangempela nayo izokwanda. Ngalesi sikhathi, oxhumana naye e-Ellipse angadlula emaphethelweni omjaho. , Amabutho angempela omjaho azoba aphakeme kunengcindezi ebaliwe ye-theory, ezodala umphetho womjaho ongawohloka kanyeukuthwala okubuthayoizokwehluleka.
Isibonelo, i-angle yokuqala yokuxhumana yeukuthwala okubuthayoI-013.40.1250 ingu-45 °.
Siyabonga ngokubukeza le ndatshana, uma unanoma yimuphi umbuzoIndandatho yokubulala, zizwe ukhululekile ukuxhumana nathi!
