Kunezinhlobo ezimbili zeindandatho yokugwazaumonakalo, omunye umonakalo womjaho, kanti omunye izinyo eliphukile.Umonakalo womjaho ungaphezu kuka-98%, ngakho izinga lomjaho liyisici esibalulekile esithinta impilo yomjaho.indandatho yokugwaza.Phakathi kwazo, ubulukhuni bendlela yomjaho, ukujula kongqimba oluqinile, i-raceway curvature radius kanye ne-engeli yokuxhumana yizinto ezine ezibaluleke kakhulu ezithinta ikhwalithi yomjaho.
1. Ubulukhuni bendlela yomjaho
Ukuqina kokuqina kweindandatho yokugwazai-raceway inomthelela omkhulu ekulayisheni kwayo okulinganiselwe okumile.Uma umthwalo omile olinganiselwe ungu-1 ku-55HRC, ubudlelwano obuhambisanayo phakathi komthwalo olinganiselwe omile we-bheringi nobulukhuni bomgwaqo womjaho bumi kanje:
| Ubulukhuni be-Raceway HRC | 60 | 59 | 58 | 57 | 56 | 55 | 53 | 50 |
| Ilinganiswe ngomthwalo omile | 1.53 | 1.39 | 1.29 | 1.16 | 1.05 | 1 | 0.82 | 0.58 |
Ii-slewing bearkusuka ku-XZWDi-slewing bearubulukhuni benkampani yomjaho ngu-55HRC~62HRC.
2.Ukujula kongqimba oluqinile lwendlela yomjaho
Ukujula okudingekile kongqimba oluqinile kuyisiqinisekiso sokuthi iindandatho yokugwazaumjaho awuhambi.Lapho i-i-slewing bearithwala umthwalo wangaphandle, ibhola lensimbi kanye nomzila womjaho ushintsha ukusuka endaweni othintana kuyo kuya kothintana nangaphezulu, futhi indawo yokuxhumana iyindawo eyi-elliptical.Ngaphezu kokucindezeleka okucindezelayo, umzila womjaho ungaphansi kwengcindezi yokugunda, futhi ukucindezeleka okukhulu kwe-shear kwenzeka ekujuleni kwe-0.47a (i-semi-axis enkulu ye-ellipse yokuxhumana) ngaphansi kwendawo, Lesi futhi isizathu esenza ukujula kongqimba oluqinile kucaciswe kuzinga ngokuya kobubanzi bebhola lensimbi esikhundleni sobubanzi beindandatho yokugwaza, futhi inani elincane eliqinisekisiwe linikezwa ezingeni.Umthwalo omile olinganiselwe C webheringi ulingana nokujula kwesendlalelo esiqinile esingu-H0.908.Uma ukujula kwesendlalelo esiqinile okudingeka ukuthi kube ngu-4mm kucinywe kuphela kube ngu-2.5mm, umthwalo omile othwalayo C uzoncishiswa ukusuka ku-1 kuye ku-0.65, amathuba okulimalai-slewing bearngenxa yokukhathala ukuxebuka kuzokwanda kakhulu.
Ngokwesibonelo, ii-slewing bearukujula kwesendlalelo somjaho013.35.1250 umgwaqo womjaho ≥ 3.5mm.
3.I-Curvature radius yomgwaqo womjaho
Irediyasi egobile yomjaho ibhekisela endaweni eyijika yomgwaqo womjaho esigabeni esime mpo.I-ratio t yerediyasi yomgwaqo womjaho oya endaweni eyingaba yebhola lensimbi nayo ithinta ngokuphawulekayo umthwalo olinganiselwe olinganiselwe nempilo yokukhathalaindandatho yokugwaza.Lapho t=1.04, umthwalo olinganiselwe olinganiselwe nempilo yokukhathala ingu-1, kanye nobudlelwano obuhambisanayo phakathi komthwalo olinganiselwe olinganiselwe nempilo yokukhathalaindandatho yokugwazafuthi t imi kanje.
| Isilinganiso se-Curvature | 1.04 | 1.06 | 1.08 | 1.10 |
| Ilinganiswe ngomthwalo omile | 1 | 0.82 | 0.72 | 0.65 |
| Impilo yokukhathala | 1 | 0.59 | 0.43 | 0.33 |
Kungabonakala kuthebula elingenhla ukuthi ubukhulu besilinganiso serediyasi, sinciphisa umthwalo olinganiselwe omile kanye nempilo yesevisi ibe mfushane.
4.Raceway contact angle
I-engeli yokuxhumana isho i-engeli ephakathi komugqa oxhuma indawo yokuxhumana yebhola lensimbi emjahweni womjaho kanye nendawo emaphakathi yebhola lensimbi kanye nesigaba se-radial (indiza evundlile)i-slewing bear.Umthwalo omile okaliwe C weindandatho yokugwazailingana ngokomugqa ne-SINα, futhi i-engeli yokuxhumana yasekuqaleni ngokuvamile ingu-45°.Lapho i-i-slewing bearinegebe, i-engeli yokuxhumana yangempela inkulu kune-engeli yokuxhumana yasekuqaleni.Uma igebe likhulu, likhulu i-engeli yokuxhumana yangempela.Ngaphakathi kwebanga legebe elishiwo yizinga, ngokuvamile lizokhuphuka ngo-2°~10°, okungukuthi, i-engeli yokuxhumana yangempela izofinyelela ku-47°~55°, okuwushintsho oluhle lomthamo wokuthwala.Kodwa uma i-engeli yokuxhumana yasekuqaleni negebe kukhulu, i-engeli yokuxhumana yangempela izodlula u-60°.Njengoba umgwaqo womjaho uguga, igebe lizokhula futhi i-engeli yokuxhumana yangempela nayo izokhula.Ngalesi sikhathi, i-ellipse yokuxhumana ingase idlule umkhawulo womjaho., Amandla angempela omgwaqo azoba phezulu kunokucindezeleka okubaliwe okungokomcabango, okuzokwenza ukuthi unqenqema lomgwaqo ugoqe futhii-slewing bearizohluleka.
Isibonelo, i-engeli yokuxhumana yoqobo ye-i-slewing bear013.40.1250 ingu-45°.
Siyabonga ngokubuyekeza lesi sihloko, uma unombuzo kusoukubhoboza indandatho, vele ukhululeke ukuxhumana nathi!
