YTOP manganese simbi caster push bvunzo mirairo

1.Rolling performance test

Chinangwa: Kuedza kutenderedza kuita kwecaster vhiri mushure mekurodha;
Midziyo yekuyedza: caster single vhiri rolling, steering performance yekuyedza muchina;
Nzira dzekuyedza: Sezvinoratidzwa mumufananidzo 1, isa caster kana vhiri pamushini wekuyedza, isa iyo yakatemerwa mutoro W pane caster padivi penzvimbo yeplumb uye isa simba pane vhiri ekisesi munzira yakachinjika. Yera iyo shoma simba F1 inodiwa kutenderedza caster kana vhiri , F1 iri kuramba kutenderera kwekasitiri kana vhiri.
Kupoterera kwevhiri rimwe chete kunoverengerwa zvichienderana nekuenzanisa (1).
pl=F1/W…… (1)
Ipo μ1 inotenderedza kuramba coefficient;
F1 inotenderedza kuramba, iyo unit ndeye Niu (N).
W akayera mutoro, muNm (N).
Kureva: propulsion F1 = mutoro W × kuramba coefficient μ1

Kutenderera kwekuita kwevhiri rimwe chete recaster kuchaenderana neyakajairwa nyika GB/T14687-2011 (Tafura 1).

2.Steering performance test

Chinangwa: Kuedza kutungamira kwepasi rose casters mushure mekurodha;
Midziyo yekuyedza: caster kutenderera inotungamira kuita bvunzo muchina.
Test Method: Sezvinoratidzwa muFig. 2, isa caster kana vhiri pamushini wekuyedza, shandisa iyo yakatemerwa mutoro W kune caster padivi penzira yeplumb, uye shandisa simba munzira yakachinjika perpendicular kuenda kumberi kwevhiri. Edza iyo shoma simba F2 kutungamira iyo caster, F2 ndiyo inotungamira kuramba kweiyo caster. Iyo coefficient yekutungamira kushorwa inoverengerwa maererano nekuenzanisa (1).
μ2=F2/W …… (1)
uko μ2 ndiyo coefficient yekutungamira kuramba.
F2 Kutungamira kuramba, muNm; W Yakatemerwa mutoro, muNm.
W akayera mutoro muNm.
kureva: kusunda simba F2 = mutoro wX kuramba coefficient μ2

Basa rekutungamira rinoenderana neyakajairwa nyika GB/T14687-2011 (Tafura 2).

3. Tsanangudzo yemaitiro ekuedzwa.
Iyo yekupikisa coefficient yemuyedzo kubva ku1, kubva ku2 kudiki, zvichiratidza kuti kudiki kupikisa, kuri nyore kushandisa, kuchinjika kuri nani: pane zvinopesana, iyo yakakura kukosha, yakakura kuramba, yakanyanya kuoma kushandisa.

4. Hukama pakati pecaster vhiri pamusoro pezvinhu, inofambiswa furemu dhisiki zvinhu, bhora zvinhu uye kuramba.
1) Iyo yakanyanya kuoma kuomarara kwecaster vhiri pamusoro (senge PA, MC, PP, simbi vhiri, nezvimwewo), iyo idiki iyo inopikisa coefficient, zviri nyore kusunda, asi zvakanyanya kuipa kwekudzivirira kwesimba. pasi uye mbeveve mhedzisiro.
2) Kana iyo pamusoro pevhiri caster iri yakapfava zvinhu (senge TPU, TPR, BR, nezvimwewo), iyo yakakura yekudzivirira coefficient, iyo yakakura simba rekutyaira rinodiwa, asi zvirinani mhedzisiro yekudzivirira pasi uye mbeveve mhedzisiro.
3) Iyo yakakwira kuomarara kweiyo inofambiswa vhiri bracket disc uye bhora zvinhu, iyo inodzika iyo inomiririra yekudzivirira coefficient uye zviri nyore kusunda.
