Mirayiridzo yeYTOP manganese steel caster push test

1. Kuedza kushanda kweRolling

Chinangwa: Kuedza mashandiro ekutenderera kwevhiri re caster mushure mekurodha;
Midziyo yekuedza: caster single wheel rolling, steering performance testing machine;
Nzira Dzekuyedza: Sezvakaratidzwa paMufananidzo 1, isa caster kana vhiri pamuchina wekuyedza, isa mutoro wakayerwa W pamuchina wekuyedza uchitevedza nzira yeplumb uye isa simba pa axle yevhiri munzira yakatwasuka. Yera simba shoma F1 rinodiwa kuti utenderedze caster kana vhiri. , F1 inodzivirira kutenderera kwe caster kana vhiri.
Kuramba kwevhiri rimwe chete kunoverengwa zvichienderana ne equation (1).
pl=F1/W…… (1)
Kupi μ1 rolling resistance coefficient;
Kudzivirira kutenderera kweF1, chikamu chacho ndiNiu (N).
Mutoro wakayerwa neW, muNm (N).
Kureva kuti: kupfungaira F1 = mutoro W × chiyero chekuramba μ1

Kufamba kwevhiri rimwe chete re caster kunofanira kuenderana nechiyero chenyika cheGB/T14687-2011 (Tafura 1).

2. Bvunzo rekushanda kwekutungamira

Chinangwa: Kuedza mashandiro ekufambisa macaster epasi rose mushure mekurodha;
Midziyo yekuedza: muchina wekuyedza mashandiro ekufambisa steering ye caster.
Nzira Yekuedza: Sezvakaratidzwa paMufananidzo 2, isa caster kana vhiri pamuchina wekuyedza, isa mutoro wakayerwa W kumuchina wekuyedza uchitevedza nzira yeplumb, uye isa simba munzira yakatwasuka yakatarisana negwara repamberi revhiri. Yera simba shoma F2 kuti utungamirire caster, F2 ndiyo kuramba kwekutyaira kwecaster. Kuwanda kwekudzivirira kwekutyaira kunoverengerwa zvichienderana ne equation (1).
μ2=F2/W …… (1)
apo μ2 ndiyo coefficient yekudzivirira kwekutyaira.
F2 Kudzivirira chikochekedzo, muNm; W Mutoro wakayerwa, muNm.
Mutoro wakayerwa neW muNm.
kureva: simba rekusunda F2=mutoro wX resistance coefficient μ2

Kushanda kwemuchina wekufambisa kunofanira kuenderana nezvinodiwa nenyika GB/T14687-2011 (Tafura 2).

3. Tsananguro yehunhu hwebvunzo.
Kudzivirira kwemuedzo kubva pa1, kubva pa2 kudiki, zvichiratidza kuti kana kuramba kudiki, zviri nyore kushandisa, zviri nani kushanduka: pane zvinopesana, kukosha kukuru, kuramba kwakanyanya, uye kushandisa kwakaoma.

4. Hukama huripo pakati pezvinhu zvinoshandisa vhiri remuchina, zvinhu zvinofambiswa nefuremu, zvinhu zvinoshandisa bhora uye zvinodzivirira.
1) Kana kuoma kwenzvimbo yevhiri re caster (senge PA, MC, PP, vhiri resimbi, nezvimwewo) kwakaoma, kana resistance coefficient yacho ikaderera, zvinova nyore kusunda, asi zvinova zvakanyanya kuipa pakudzivirira kwepasi uye mute effect.
2) Kana pamusoro pevhiri remuchina wekugadzira zvinhu zvakapfava (senge TPU, TPR, BR, nezvimwewo), simba rekudzivirira rinodiwa, asi simba rekudzivirira pasi uye mute effect rinoita zviri nani.
3) Kana kuomarara kwedhisiki rebhureki revhiri rinofambiswa uye zvinhu zvebhora kwakakwira, chiyero chekudzivirira kutenderera chinodzikira uye zviri nyore kusunda.
