YTOP manganese steel caster thawb cov lus qhia

1.Rolling kev xeem

Lub hom phiaj: txhawm rau ntsuas qhov kev ua tau zoo ntawm lub log caster tom qab thauj khoom;
Cov khoom siv kuaj: caster ib lub log dov, lub zog ua haujlwm ntsuas tshuab;
Txoj Kev Xeem: Raws li pom hauv daim duab 1, nruab lub caster lossis lub log ntawm lub tshuab kuaj, siv cov khoom ntsuas W ntawm lub caster raws cov kav dej thiab siv lub zog ntawm lub log qag nyob rau hauv txoj kab rov tav. Ntsuas qhov tsawg kawg nkaus quab yuam F1 yuav tsum tau tig lub caster los yog lub log , F1 yog qhov tsis kam rau kev sib hloov ntawm lub caster lossis lub log.
Lub dov tsis kam ntawm ib lub log yog xam raws li qhov sib npaug (1).
pl=F1/W…… (1)
Qhov twg μ1 dov kuj coefficient;
F1 dov tsis kam, chav tsev yog Niu (N).
W rated load, hauv Nm (N).
Ntawd yog: propulsion F1 = load W × resistance coefficient μ1

Kev ua tau zoo ntawm ib lub log ntawm lub caster yuav tsum ua raws li lub teb chaws tus qauv GB / T14687-2011 (Table 1).

2.Steering kev xeem ua haujlwm

Lub hom phiaj: txhawm rau ntsuas qhov kev ua tau zoo ntawm cov casters universal tom qab thauj khoom;
Cov khoom siv kuaj: caster rotation steering kev ua tau zoo kuaj tshuab.
Test Method: Raws li pom nyob rau hauv daim duab 2, nruab lub caster los yog lub log ntawm lub tshuab kuaj, siv lub rated load W mus rau lub caster raws li cov kav dej kev taw qhia, thiab siv lub zog nyob rau hauv txoj kab rov tav perpendicular mus rau pem hauv ntej ntawm lub log. Ntsuas qhov tsawg kawg nkaus quab yuam F2 los tswj lub caster, F2 yog lub steering tsis kam ntawm lub caster. Lub coefficient ntawm steering resistance yog xam raws li kev sib npaug (1).
μ2 = F2/W …… (1)
qhov twg μ2 yog tus coefficient ntawm steering resistance.
F2 Steering tsis kam, hauv Nm; W Rated load, hauv Nm.
W rated load hauv Nm.
xws li: thawb quab yuam F2 = load wX kuj coefficient μ2

Kev ua haujlwm ntawm lub kauj yuav tsum ua raws li lub teb chaws tus qauv GB / T14687-2011 (Table 2).

3. Kev piav qhia ntawm qhov ntsuas qhov ntsuas.
Qhov kev tiv thaiv coefficient ntawm qhov kev xeem los ntawm 1, los ntawm 2 qhov me me, qhia tau hais tias qhov me me ntawm qhov tsis kam, qhov yooj yim rau siv, yooj yim dua: ntawm qhov tsis sib xws, qhov loj dua tus nqi, qhov ntau dua qhov tsis kam, ntau zog siv.

4. Kev sib raug zoo ntawm cov khoom siv log caster, txav thav duab disc khoom, cov khoom siv pob thiab tsis kam.
1) Lub hardness ntawm caster log nto (xws li PA, MC, PP, hlau log, thiab lwm yam), qhov me me ntawm cov coefficient tsis kam, nws yooj yim dua rau thawb, tab sis qhov phem dua yog rau kev tiv thaiv cov nyhuv. av thiab cov nyhuv mute.
2) Thaum lub npoo ntawm caster log yog cov khoom muag (xws li TPU, TPR, BR, thiab lwm yam), ntau dua cov coefficient tsis kam, qhov ntau dua qhov yuav tsum tau tsav tsheb, tab sis qhov zoo dua qhov kev tiv thaiv hauv av thiab cov nyhuv tsis zoo.
3) Qhov siab dua qhov hardness ntawm lub log log bracket disc thiab cov khoom siv pob, qhov qis dua ntawm lub kauj coefficient thiab qhov yooj yim dua yog thawb.
