Irola

I-roller iyithuluzi lokudlulisela ngomshini elakhiwe ama-bearings nama-roller, asetshenziselwa ukudlulisa amandla kanye nesisindo ngesikhathi sokuzungezisa. Ithola ukusetshenziswa okubanzi kuyo yonke imikhakha yezimboni ehlukahlukene efana nensimbi, i-petroleum, amakhemikhali, kanye nokukhiqizwa kwemishini.

I-roller ingahlukaniswa ngokweseka i-roller, i-transmission roller, ne-guiding roller. Lesi sihloko sizogxila ikakhulukazi ekusetshenzisweni kwalezi zinhlobo zamarola.

Okokuqala, i-roller esekelayo yizinto ezivamile zemishini ezisetshenziselwa ukusekela kanye nokuzinzisa izingxenye ezijikelezayo kumishini. Ngokwesibonelo, embonini yensimbi, babekezelela amazinga okushisa aphakeme nezingcindezi ngaphakathi kweziko futhi bathwala imithwalo esindayo. Embonini ye-petroleum, ziyingxenye yezinhlelo zokumpompa izinduku emithonjeni kawoyela, zibekezelela amandla aphezulu kanye namandla acindezelayo. Ekwenziweni ngomshini, abalulekile kumathuluzi emishini ehlukene, akwazi ukumelana nokujikeleza ngesivinini esikhulu kanye nokudluliswa kwetorque.

Okwesibili, i-roller yokudlulisela ibalulekile kumandla kanye nokudluliswa kwe-torque. Emkhakheni wezimoto, basiza ukushintshwa kwegiya ekuhanjisweni. Ekwenziweni kwamandla omoya, ziyizingxenye ezibalulekile ezinjinini zomoya eziguqula amandla omoya abe amandla kagesi. Ekwenziweni kwemishini, baqashwa kumathuluzi emishini ahlukahlukene okuhambisa izinto zokusebenza ezihlukene.

Okokugcina, i-guiding roller isetshenziselwa ukuqondisa nokubeka izingxenye ezihambayo ngaphakathi kwemishini. Embonini yensimbi, baqinisekisa ukubekwa okuqondile nokulawulwa kwezingots zensimbi emishinini yokuphonsa eqhubekayo. Emkhakheni we-petroleum, zenza kube lula ukubeka kanye nokulawula amasistimu okufaka amabhokisi emithonjeni kawoyela. Ekwenziweni ngomshini, zibalulekile ekubekweni okuqondile kanye nokulawulwa kwezinto zokusebenza kumathuluzi omshini ahlukahlukene.

Sengiphetha, i-roller idlala izindima ezibalulekile njengamathuluzi okuhambisa ngomshini abalulekile kuzo zonke izimboni, anezinhlelo ezihlukahlukene nezibanzi.
