Kuid kuigi need n\u00e4evad v\u00e4lja sarnased ja neil on sarnased omadused, on need kaks ainulaadset kinnitusvahendit, millel on oma unikaalsed rakendused. Niisiis, mis vahe on poltidel ja kruvidel?<\/p>\n<p>Masina k\u00e4siraamatus selgitatakse, et keermestamata objektide k\u00fclge kinnitamiseks kasutatakse polte, tavaliselt mutrit kasutades. V\u00f5rdluseks kasutatakse keermega objektide kokkupanemiseks kruvisid. Siin on aga asi: mitte k\u00f5igil objektidel, milles kruvisid kasutatakse, pole juba keermeid. M\u00f5nel objektil on eelnevalt valmistatud keermed, samas kui teised loovad keerme kruvi paigaldamise ajal. Niisiis, p\u00f5hiline erinevus kruvide ja poltide vahel seisneb selles, et esimest kasutatakse keermestatud esemete kokkupanemiseks, teist aga turvismata esemete kokkupanemiseks. Seda arvestades saavad kruvid paigaldusprotsessi ajal ise keermestada.<\/p>\n<p>Samuti v\u00e4\u00e4rib m\u00e4rkimist, et \u00fchenduskoha kokkupanemiseks tuleb kruvisid keerata, poldid saab aga paigale kinnitada t\u00f6\u00f6riista v\u00f5i kelgupoldi abil. Polte kasutatakse tavaliselt polt\u00fchenduse tegemiseks, kasutades j\u00f5u rakendamiseks mutrit, samal ajal kui varre kasutatakse t\u00fc\u00fcblina. See kinnitab liigendi sisuliselt k\u00fclgsuunaliste j\u00f5udude vastu. Ja seet\u00f5ttu on paljudel poltidel keermeta vars (tuntud kui k\u00e4epideme pikkus); seega muudab need t\u00fc\u00fcblite jaoks t\u00f5husamaks.<\/p>\n<p>Seal on k\u00fcmneid erinevat t\u00fc\u00fcpi polte, millest m\u00f5ned h\u00f5lmavad ankrupolte, lehtpolte, liftipolte, riputuspolte, kuuskantpolte, J-polte, viivituspolte, kivipolte, \u00f5lapolte ja U-polte. Lisaks on poldid saadaval paljudest materjalidest, sealhulgas terasest, roostevabast terasest, pronksist, messingist ja nailonist. Statistika n\u00e4itab aga, et kuni 90% k\u00f5igist poltidest on valmistatud terasest, mist\u00f5ttu on see tootmisettev\u00f5tete seas eelistatud valik.<\/p>\n<p>Samuti on saadaval k\u00fcmneid erinevat t\u00fc\u00fcpi kruvisid, millest m\u00f5ned h\u00f5lmavad puitlaastplaadikruvisid, puitlaastplaadikruvisid, tekikruvisid, ajamkruvisid, vasarkruvisid, kipsplaadikruvisid, silmuskruvisid, t\u00fc\u00fcblikruvisid, puidukruvisid, twinfast kruvisid, turvapeakruvisid ja lehtmetallikruvisid. M\u00f5ned erineva pea kujuga kruvid on saadaval, sealhulgas pann, n\u00f6\u00f6p, \u00fcmmargune, seenekujuline, ovaalne, k\u00fchm, juust, t\u00e4idis ja \u00e4\u00e4rik. Ja nagu nende poltidega analoogid, on ka kruvid saadaval erinevatest materjalidest.<\/p>\n<p>P\u00e4rast selle lugemist peaksite paremini m\u00f5istma kruvide ja poltide erinevust.<\/p>","protected":false},"excerpt":{"rendered":"<p>\u00a0\u00a0\u00a0 It\u2019s a common assumption that bolts are screws refer to the same fastening hardware.
