Screw threads inogona kuwanzoonekwa mune zvakawanda zvemakanika zvikamu. Vane maapplication akawanda. Pane zvinhu zvakasiyana-siyana zvekuva nazvo. Vanogona kushandiswa kumisa. Zvikukuru,nut-bolts uye studsane screw threads anoshandiswa kugadzirisa kwechinguva chikamu chimwe kune chimwe chikamu. Iwo anoshandiswa kujoina senge co-axial kujoinwa kwetsvimbo, uye machubhu, etc. Anogona kushandiswa kutapurirana mafambiro uye simba senge lead screws yemuchina maturusi. Kunze kwezvo, ivo vanogona zvakare kuisirwa kuendesa uye kusvina zvinhu. Semuenzaniso, vari mune screw conveyor, jekiseni rekugadzira muchina, uye screw pump, nezvimwe.
Screw threads inogona kugadzirwa nenzira dzakasiyana siyana. Yokutanga ndeyekukanda. Inongova neshinda shoma pane hurefu hupfupi. Iine kushoma kurongeka uye kupera kwakashata. Yechipiri ndiyo nzira yekubvisa (machining). Iyo inopedzwa neakasiyana ekucheka maturusi mune akasiyana emuchina maturusi senge lathes, milling muchina, yekudhirowa michina (ine tapping attachment) zvichingodaro. Izvi zvinonyanya kushandiswa pakukwirira kwepamusoro uye kupedzisa. Uye inoshandiswa kune dzakasiyana siyana dzeshinda uye huwandu hwekugadzirwa kubva pachidimbu kusvika pakugadzirwa kwakawanda.
Yechitatu ndiyo yekuumba (kukunguruka). Iyi nzira inewo maitiro akawanda. Semuyenzaniso, blanks yesimbi yakasimba ductile sesimbi inokungurutswa pakati pemashinda ane shinda. Shinda hombe dzinopisa dzakakungurutswa dzichiteverwa nekupedzisa uye shinda diki dzakatwasuka dzinotonhora dzichikungurutswa kusvika pakupera kwaunoda. Uye kutonhora kukunguruka kunopa simba rakawanda uye kuoma kune zvikamu zvakarukwa. Iyi nzira inoshandiswa zvakanyanya pakugadzirwa kwemafasteners senge mabhaudhi, screws nezvimwe.
Mukuwedzera, kukuya inzira huru yekugadzira screw threads. Inowanzo itirwa kupedzisa (kurongeka uye pamusoro) mushure mekuita nemachining kana kupisa kukungurutswa asi inowanzo shandirwa kune yakananga shinda pamatanda. Shinda dzakasimba pane dzakaomarara kana pamusoro dzakaomeswa zvikamu zvinopedzwa kana kuti zvakananga kugadzirwa nekukuya chete. Inoshandiswa kune dzakasiyana siyana dzemhando uye saizi yeshinda uye huwandu hwekugadzira.
Screw threads inogona kupatsanurwa mumhando dzakasiyana-siyana zvichienderana nemhando dzakasiyana nzira. Zvinoenderana nenzvimbo, kune ekunze screw thread (semuenzaniso, pamabhaudhi) uye yemukati screw thread (semuenzaniso, munzungu). Kune akatwasuka (helical) (semuenzaniso, mabhaudhi, matudhi), taper (helical), (semuenzaniso, mu drill chuck), uye radial (mupumburu) semu self centering chuck kana yakamurwa zvinoenderana nekumisikidzwa. Pamusoro pezvo, kune shinda dzakajairwa (dzinowanzo fararira tambo), shinda dzepombi uye shinda dzakatsetseka (kazhinji dzeuchapupu hunobvinza) kana dzakapatsanurwa maererano nekukochekerana kana kunaka kweshinda.
Pachine zvimwe zvakawanda zvezvikamu. Zvese mune zvese, isu tinogona kutora mhedziso yekuti screw shinda dzine huwandu hwakakura kwazvo hwekushandisa. Mabasa avo nemaitiro akakodzera kudzidza kwedu.
