Kukho iindidi ezimbini zeumsesane wokuxhelaumonakalo, omnye ngumonakalo wendlela yomdyarho, kwaye enye lizinyo eliqhekekileyo.Umonakalo wendlela yomdyarho ungaphezulu kwe-98%, ngoko ke umgangatho wendlela yogqatso yeyona nto iphambili echaphazela ubomi bomdyarho.umsesane wokuxhela.Phakathi kwazo, ubulukhuni bendlela yomdyarho, ubunzulu obuqinileyo bomaleko, iradiyasi yomdyarho wegophe kunye ne-engile yoqhagamshelwano zezona zinto zine zibalulekileyo ezichaphazela umgangatho wendlela yomdyarho.
1. Ubunzima bomdyarho
Ukucima ukuqina kweumsesane wokuxhelaumzila womdyarho unempembelelo enkulu kumthwalo wayo olinganiselweyo.Ukuba umthwalo ongatshintshiyo olinganiselweyo ngu-1 kwi-55HRC, unxulumano oluhambelanayo phakathi komthwalo ongatshintshiyo olinganiselweyo wokuthwala kunye nobulukhuni bendlela yogqatso ngolu hlobo lulandelayo:
| Umdyarho ubulukhuni HRC | 60 | 59 | 58 | 57 | 56 | 55 | 53 | 50 |
| Ilinganiswe umthwalo omileyo | 1.53 | 1.39 | 1.29 | 1.16 | 1.05 | 1 | 0.82 | 0.58 |
Iibhere yokubulalaukusuka kwi-XZWDibhere yokubulalaubulukhuni bendlela yomdyarho yenkampani yi-55HRC ~ 62HRC.
2.Ubunzulu bomaleko oqinileyo wendlela yomdyarho
Ubunzulu obuyimfuneko bomaleko lukhuni sisiqinisekiso sokubaumsesane wokuxhelaindlela yokubaleka ayichaphazeli.Xa iibhere yokubulalaithwala umthwalo wangaphandle, ibhola yensimbi kunye nenguqu yomzila ukusuka kwindawo yokudibanisa ukuya kwindawo yokudibanisa, kwaye indawo yokudibanisa i-elliptical surface.Ukongeza kuxinzelelo loxinzelelo, umdyarho uphantsi koxinzelelo lokucheba, kwaye olona xinzelelo luphezulu lwe-chear lwenzeka kubunzulu be-0.47a (i-semi-axis enkulu ye-ellipse yoqhagamshelwano) ngaphantsi komhlaba, Esi sisizathu sokuba kutheni lukhuni umaleko ubunzulu icaciswe kumgangatho ngokobubanzi ibhola yentsimbi endaweni ubukhuluumsesane wokuxhela, kunye nexabiso elincinci eliqinisekisiweyo linikezelwa kumgangatho.Umthamo we-static olinganisiweyo we-C wokuthwala ulingana nobunzulu bomaleko obunzima H0.908.Ukuba ubunzulu bomaleko obunzima obufunekayo ukuba bube yi-4mm bucinywe kuphela kwi-2.5mm, ukuthwala umthwalo omileyo we-C uya kuncitshiswa ukusuka kwi-1 ukuya kwi-0.65, amathuba okuba umonakaloibhere yokubulalangenxa yokudinwa ukuxobuka kuya kwandiswa kakhulu.
Umzekelo, iibhere yokubulalaUmdyarho wendlela yogqatso ubunzulu013.35.1250 umdyarho yi ≥ 3.5mm.
3.Iradiyasi yeCurvature yendlela yomdyarho
Ireyidi yomzila wegophe ibhekisa kwiradiyasi egobileyo yendlela yogqatso kwicandelo elithe nkqo.Umyinge werediyasi yendlela yomdyarho ukuya kwiradiyasi yebhola yentsimbi ikwachaphazela ngokubalulekileyo umthwalo ongatshintshiyo kunye nobomi bokudinwaumsesane wokuxhela.Xa i-t=1.04, umthwalo ongatshintshiyo olinganiselweyo kunye nobomi bokudinwa yi-1, kunye nobudlelwane obuhambelanayo phakathi komthwalo olinganiselweyo kunye nobomi bokudinwaumsesane wokuxhelakwaye u-t umi ngolu hlobo lulandelayo.
| Umlinganiselo weCurvature | 1.04 | 1.06 | 1.08 | 1.10 |
| Ilinganiswe umthwalo omileyo | 1 | 0.82 | 0.72 | 0.65 |
| Ubomi bokudinwa | 1 | 0.59 | 0.43 | 0.33 |
Inokubonwa kwitheyibhile engentla ukuba inkulu i-radius ratio, isezantsi i-static load rated kunye mfutshane ubomi benkonzo.
4.I-engile yoqhagamshelwano lweRaceway
I-angle yoqhagamshelwano ibhekiselele kwi-engile phakathi komgca odibanisa indawo yoqhagamshelwano yebhola yentsimbi kwindlela yokugijima kunye nombindi webhola yentsimbi kunye necandelo le-radial (inqwelo-moya ethe tye)ibhere yokubulala.Umthwalo omileyo okalisiweyo C weumsesane wokuxhelailingana ngokomgca ne-SINα, kwaye i-engile yoqhagamshelwano yoqobo iqhele ukuba yi-45°.Xa iibhere yokubulalainomsantsa, i-engile yoqhagamshelwano yokwenene inkulu kuneyokuqala yoqhagamshelwano.Umkhulu umsantsa, inkulu eyona engile yoqhagamshelwano.Ngaphakathi koluhlu lwe-gap oluchazwe ngumgangatho, ngokuqhelekileyo luya kunyuka ngo-2 ° ~ 10 °, oko kukuthi, i-angle yokudibanisa yokwenene iya kufikelela kwi-47 ° ~ 55 °, olona lutshintsho olulungileyo kumandla okuthwala.Kodwa ukuba i-angle yoqhagamshelwano yasekuqaleni kunye ne-gap inkulu, i-angle yoqhagamshelwano yangempela iya kudlula i-60 °.Njengoko i-raceway inxiba, i-gap iya kwanda ngakumbi kwaye i-angle yoqhagamshelwano yokwenene nayo iya kwanda.Ngeli xesha, i-ellipse yoqhagamshelwano inokugqithisa umda wendlela yokugijima., Awona mandla endlela yomdyarho ayakuba phezulu kunoxinzelelo olubaliweyo lwethiyori, nto leyo eya kubangela ukuba umda wendlela yogqatso iwe kwayeibhere yokubulalaiya kusilela.
Umzekelo, i-engile yoqhagamshelwano yokuqala yeibhere yokubulala013.40.1250 yi-45 °.
Enkosi ngokuphonononga eli nqaku, ukuba unombuzoumsesane obulalayo, vele ukhululeke ukudibana nathi!
