Mokhoa oa ho khetha mochini o roalang poleiti o loketseng

Ho khetha poleiti e loketseng Mochini oa Rolling e hloka ho shebisisa ka botlalo thepa le botenya ba poleiti e lokelang ho phuthoa. Tse latelang ke mefuta e meng e tloaelehileng ea mochini oa ho roala lipoleiti le maemo a eona a sebetsang:

1. Mochini oa li-roller plate tse peli: o loketse ho roala lipoleiti tse tšesaane tse nang le matla a phahameng a 6-10mm.

2. Symmetrical tse tharo-rolara mochini rolara: sebopeho se bonolo, e pharaletseng ea kopo mefuta e fapaneng, empa ha ho mosebetsi pele ho koba, e setseng e otlolohileng bohale ka mor'a hore ho kolokisoa ke e khōlō, 'me ho hlokahala hore u reke lisebelisoa tse eketsehileng tsa ho hatella bohale. E loketse lipoleiti tsa botenya bo fapaneng, empa hangata e sebelisoa bakeng sa ho roala lipoleiti tse mahareng le tse tšesaane.

3. Mochini oa ho roala poleiti ea li-asymmetric tse tharo: o na le ts'ebetso ea pele ea ho kobeha ka lehlakoreng le le leng. Haeba mahlakore ka bobeli a poleiti a hloka ho kobeha pele, e hloka ho reteleha. E loketse lipoleiti tse mahareng le tse tšesaane.

4. Phetoho e otlolohileng ho theosa le mochini o rollang lipoleiti tse tharo: o ka etsa litsela tse peli tse kobehang pele, tse loketseng lipoleiti tse mahareng le tse tšesaane, tse ka bolokang nako ea ho sebetsa lipoleiti haholo.

5. Ho sekamela ho ea tlase ho fetola mochine o roalang lipoleiti tse tharo: o ka boela oa etsa litsela tse peli pele ho koba, ho roala le ho koba pele ho hloka feela ho fepa, hape ho loketse lipoleiti tse mahareng le tse tšesaane.

6. Horizontal downward phetoho tse tharo-rolara poleiti rolara mochini: e ka ba pele ho kobeha ka mahlakoreng a mabeli, a loketse bakeng sa ho roala lipoleiti tse fapa-fapaneng botenya, haholo-holo bakeng sa ho roala lipoleiti tse mahareng le tse teteaneng.

7. Arc ho theosa ho fetola mochini o rollang lipoleiti tse tharo: e ka ba e kobehileng ka mahlakoreng ka bobeli, e loketse lipoleiti tse kolobang tse nang le botenya bo ka tlase ho 80mm, e batlang e le molemong oa ho roala lipoleiti tse teteaneng.

8. Mochini oa bokahohleng oa li-roller plate tse tharo o nang le rolara e ka holimo: rolara e ka holimo e ka tsamaea ka bobeli ka ho toba le ka holimo, e ka ba e kobehileng ka mahlakoreng ka bobeli, 'me e loketse lipoleiti tse nang le botenya ba 80-100mm.

9. Mochini oa ho roala lipoleiti tse 'nè: ka mokhoa o nepahetseng haholoanyane, o ka roala lipoleiti tse nang le botenya ba 80-100mm,' me o na le bokhoni bo phahameng ba ho roala. E arotsoe ka mofuta o tloaelehileng le mofuta oa arc. Rolara e ka holimo ea mofuta o tloaelehileng e tsitsitse ebile e pota-potiloe, e tlaase e phahamisoa ka holimo, 'me li-roller ka mahlakoreng ka bobeli li tsitsitse ebile li phahamisitsoe; mokhoa oa ho sisinyeha oa li-rollers tse ka holimo le tse ka tlaase tsa mofuta oa arc o tšoana le oa mofuta o tloaelehileng, 'me li-roller ka mahlakoreng ka bobeli li phahamisoa ebe li theoleloa ka har'a arc ho potoloha ntlha e tsitsitseng.
