Ijubane lokujikeleza lesikhungo esikhulu se- icima ithuluzi lomshini kukhethwe?

Ukukhethwa kwejubane lokujikeleza lapho umsebenzi wokucima usushisiwe. Ukusuka kokufana kokushisa kokusebenza, isivinini sokujikeleza sishesha, kuncipha ithonya lokungalingani kwamazinga okushisa okubangelwa igebe elingalingani phakathi kwe-inductor nendawo yokusebenza. Amathuluzi omshini wokucisha kusenesikhathi ngokuvamile asetha ibanga lejubane elingu-60-300 / min. Amanye amathuluzi emishini anokushintshwa kwejubane okungenasinyathelo, kanti amanye amathuluzi emishini asebenzisa ushintsho lwejubane olunganyatheli, umsebenzisi angalukhetha ngokuthanda kwakhe. Kodwa-ke, amanye amathuluzi emishini anejubane eliphansi ngokweqile ngenxa yezimo ezithile. Ngokwesibonelo, crankshaft iphephabhuku rotary lukhuni umshini, isivinini iphephabhuku main ngokuvamile 60r / iminithi, ngenkathi yokuxhuma induku ijubane iphephabhuku 30r / iminithi. Lokhu kungenxa yokuthi intambo yokuxhuma yentambo ijikeleza emshinini wokwenza lukhuni ngokusebenzisa indlela yejingi (isakhiwo senduku esixhunywe kane). Uma ijubane lokujikeleza lishesha kakhulu, inzwa yendandatho yesiqingatha ayikwazi ukuhamba kahle kulo lonke iphephabhuku, ngakho-ke ingazungeza ngejubane eliphansi lama-30r / min. Lesi sivinini asifanele ukushisa kwephephabhuku. Ijenali eyinhloko isebenzisa i-60r / Min yisizathu sokuthi ukwakheka kungaba lula ngenxa yokusetshenziswa kwemoto enejubane ezimbili.

Kukhona impikiswano yokuthi ukukhethwa kwejubane kufanele kucatshangelwe kumjikelezo wokushisa we-workpiece. Umsebenzi wokusebenza kufanele uzungeziswe hhayi ngaphansi kwezikhathi eziyi-10 kumjikelezo wokushisa ukuqinisekisa ukushisa okufanayo ngomjikelezo wobuciko. Ngokwalesi sibalo, isikhathi sokushisa sokungeniswa kwento yokusebenza ejwayelekile imvamisa iphakathi kwama-5-10s. Uma kungu-5s kuya ku-10 revolutions, kungu-120r / min. Uma kungu-10s kuya ku-10 revolutions, ijubane lingu-60r / min.

Ngokuthuthuka kwejubane lokushisa lokungeniswa, kwamagiya okushisa afanayo ama-frequency-frequency, isikhathi sokushisa samagiya sifinyelelwe ku-0.1-0.2s. Ngakho-ke, izidingo zejubane lomsebenzi ziyanda njalo, futhi ijubane eliphezulu lokuphotha lamathuluzi wokucisha umshini lifinyelele kubantu abayi-1600 / min. Njengamanje, kuyaqabukela ukuthi ijubane lomshini wokucisha umshini lifike kuma-600r / min. Ngaphezu kwalokho, isivinini sokujikeleza komsebenzi sibuye sihlobene kakhulu nokupholisa. Kumagiya nakuma-spline shafts, ukucima nokupholisa kuvame ukusebenzisa indlela yokufafaza uketshezi. Ukuzungezisa into yokusebenza kushesha kakhulu, futhi uketshezi olucimayo alwanele ukupholisa uhlangothi olulodwa lwezinyo. Ngakho-ke, ijubane lethuluzi lomshini wokucima lisaqhubeka liyi-600r / min noma i-300r / min njengomkhawulo ongaphezulu. Ngaphezu kwalokho, kuyadingeka ukuthi kuthuthukiswe izinto ezisebenza ngomshini noma ngogesi ezinganciphisa ijubane lomsebenzi wokusebenza ngesikhathi ngemuva kokuphothulwa kokushisa, ukuze umsebenzi wokusebenza uzungeze ngokushesha ukufeza ukushisa okufanayo, kepha futhi ujikeleze kancane ukufeza izidingo zomfaniswano ukupholisa okokusebenza kwamagiya.
