Six Rewards of Tapered Pulley:

one. Very good interchangeability: tapered sleeve pulley is appropriate for different occasions. When the transmission component operates for a prolonged time, the internal hole and the chain groove may possibly be damaged. If it is a transmission portion making use of this kind of tapered sleeve, when this transpires, exchange the tapered sleeve with the specific specification, and it can be utilised once more. For that reason, the provider daily life of the transmission components is significantly enhanced, the routine maintenance expense is reduced, and time is saved.

two. Higher flexibility: The separation of the pulley and the tapered sleeve helps make the adjust of the shaft hole only require to modify the diameter of the tapered sleeve, which increases the product’s flexibility and significantly decreases the stock variety and price of the product.

three. Easy set up and disassembly: only a a single-inch hexagonal wrench is needed, no other special instruments are required, and it can be accomplished in just 1 minute, which is hassle-free and rapidly.

four. Permit broader shaft diameter tolerance: +.05mm to -.125mm. The groove can be geared up with V-belt, a slender V-belt, and so on. Light and light to medium masses enable keyless transmission.

5. Produced in stringent accordance with the worldwide common DIN2211, all goods have been analyzed by harmony to stay away from damage to motor bearings and gear factors caused by beating.

6. Surface area anti-rust therapy: After phosphating and blackening, the surface is smooth, beautiful, and dust-evidence.

Važnost remenica

Kolotura je kotač koji se kreće na osovini ili osovini. Svrha remenice je mijenjanje smjera zatezne sajle. Kabel zatim prenosi snagu s osovine na remenicu. Ovaj članak objašnjava važnost remenica i pokazuje nekoliko različitih namjena ovog stroja. Također pogledajte odjeljak Mehaničke prednosti u nastavku za različite vrste. Počnimo.
kotur

jednostavan stroj

Jednostavni stroj s remenicama je uređaj koji se koristi za prijenos energije. Sastoji se od kotača s fleksibilnim materijalom na rubu i užeta ili lanca vezanog za drugi kraj. Zatim podignite teret koristeći silu primijenjenu na drugi kraj. Mehanička prednost ovog sustava je jedna, budući da je sila primijenjena na teret jednaka sili na osovini remenice.
Jednostavan stroj s remenicama ima mnoge prednosti, od mogućnosti izgradnje piramida do izgradnje modernih zgrada s njim. Koloturnici su također popularni među djecom jer mogu obavljati jednostavne zadatke poput podizanja igračaka na tobogan, skliznuća s tobogana i ponovnog podizanja. Ove aktivnosti, koje teoretičari dječjeg razvoja nazivaju "prijevoz", omogućuju im da u procesu uče o fizici jednostavnih strojeva.
Mehanizam radi pomoću kablova za prijenos sile. Kabel je pričvršćen na jednu stranu remenice, a drugu stranu povlači korisnik. Podignite teret povlačenjem jednog i drugog kraja užeta. Jednostavni strojevi s remenicama imaju mnoge komercijalne i svakodnevne primjene, uključujući pomoć pri pomicanju velikih predmeta. Mogu biti fiksni ili pokretni, a mogu biti i kombinacija oba. Ovaj izum izvrstan je alat za svakog početnika ili inženjera.

os

Kotač osovine je osnovni mehanički dio koji pojačava silu. Možda se izvorno pojavio kao alat za podizanje kanti ili teških predmeta iz bunara. Njegov rad demonstriraju veliki i mali zupčanici pričvršćeni na istu osovinu. Kada se primijeni na objekt, sila na velikom zupčaniku F nadvladava silu W na zupčaniku R. Omjer ovih dviju sila naziva se mehanička prednost.
Idealna mehanička prednost remenica osovine je njihov omjer radijusa. Veliki radijus rezultirat će većom mehaničkom prednošću nego mali radijus. Kolotura je kotač kroz koji prolazi uže ili remen. Često su kotači međusobno povezani kabelima ili remenima za dodatnu mehaničku prednost. Broj potpornih užadi ovisi o željenoj mehaničkoj prednosti remenice.
U dizajnu kotača osovine, osovina je uporište, a vanjski rub je ručka. Jednostavno rečeno, kotači i osovinske remenice su poboljšane verzije poluga. Kolotur osovine pomiče teret dalje od poluge i povezuje se s teretom u središtu osovine. Remenice vratila su svestrane i naširoko se koriste u građevinarstvu.

uže ili remen

Užad ili remenice mehanički su uređaji koji se koriste za pomicanje velikih masa. Uže nosi veliku masu i može se lako pomicati primjenom sile koja je jednaka jednoj četvrtini mase na labavi kraj. Četverostruke remenice imaju četiri kotača i pružaju mehaničku prednost četiri kotača. Često se koristi u tvornicama i radionicama. Također je popularan izbor u građevinskoj industriji. Ako ugrađujete remenicu u svoje vozilo, svakako slijedite ove jednostavne upute za ugradnju.
Prvo morate razumjeti osnove rada užeta ili kolotura. Stroj se sastoji od jednog ili više kotača koji se okreću na osovini. Uže ili remen je omotan oko remenice i sila koja djeluje na uže se širi oko remenice. Zatim prenosi silu s jednog kraja užeta na drugi. Sustav remenica također pomaže u smanjenju sile potrebne za podizanje predmeta.
Drugo uobičajeno uže ili remenica je remenica diferencijala. Ovo je slično remenici za uže, ali se sastoji od dvije remenice različitih radijusa. Napetost u dvije polovice užeta podržava polovicu tereta koji bi remenica pod naponom trebala nositi. Ove dvije različite vrste remenica često se koriste zajedno u sustavima kompozitnih remenica.

Mehanička prednost

Mehanička prednost je omjer sile koja se koristi za pomicanje tereta kroz sustav remenica i primijenjene sile. Korišten je za mjerenje učinkovitosti sustava remenica, ali također zahtijeva pretpostavke o primijenjenim silama i težinama. U jednostavnom sustavu kolotura 1:1, težina koja podiže uteg jednaka je težini osobe koja vuče uteg. Dodavanje mehaničke prednosti može pomoći nadomjestiti nedostatak radne snage.
Ova prednost proizlazi iz mehaničkih svojstava jednostavnih strojeva. Zahtijeva manje snage i zauzima manje prostora i vremena za postizanje istog zadatka. Isti učinak može se postići i primjenom manje sile na daljinu. Nadalje, ovaj se učinak naziva omjer izlazne sile. Osnovni princip rada sustava kolotura je uže s fiksnom točkom na jednom kraju. Pomična remenica može se pomicati s vrlo malo sile kako bi se postigao željeni učinak.
Teret se može pomicati kroz okomiti ulaz pomoću jednostavnog sustava remenica. Može koristiti jednostavan sustav "kolotura" s 2:1 "okvirom ljestava" ili 4:1 s dvostrukim remenicama. Ovo se može kombinirati s drugim jednostavnim sustavom remenica kako bi se stvorio složeni sustav remenica. U ovom slučaju, jednostavan sustav remenica vuče drugu remenicu, dajući joj mehaničku prednost od 9:1.

Uobičajeno

Vjerojatno ste vidjeli sustave remenica u svojoj kuhinji ili praonici. Vjerojatno ga već koristite za vješanje odjeće na podesivi uže za rublje. Možda ste vidjeli motorne remenice u kuhinjama poslovnih zgrada. Možda ste ga čak vidjeli na kranu. Ovi strojevi koriste sustav remenica koji im pomaže u podizanju teških tereta. Isto vrijedi i za kazališta. Neke remenice pričvršćene su na strane pozornice, omogućujući operateru pomicanje gore-dolje po pozornici.
Sustavi remenica imaju mnoge namjene u naftnoj i naftnoj industriji. Na primjer, u industriji nafte i plina, sustavi remenica koriste se za polaganje kabela. Oni su raspoređeni u strukturu remenice da daju mehaničku energiju. Kada uže radi, dvije remenice obješene su na dizalicu kako bi se omogućilo glatko kretanje. U ovim primjenama, remenice su vrlo učinkovite u podizanju teških predmeta.
Kolotura je jednostavna mehanička naprava koja mehaničku energiju pretvara u gibanje. Za razliku od lanaca, remenice su dizajnirane za prijenos snage s jednog mjesta na drugo. Sila potrebna za podizanje predmeta s koloturom jednaka je onoj koja je potrebna rukom. Potrebna je ista količina sile za podizanje kante s vodom, ali je ugodnije vući u stranu. Kanta s vodom teži isto kao kad se podigne okomito, pa je lako vidjeti kako ovaj mehanizam može biti koristan.

Obavijest o sigurnosti

Kada koristite remenice, trebali biste poduzeti nekoliko sigurnosnih mjera kako biste zaštitili svoje zaposlenike i druge radnike na gradilištu. Osim zaštitnog šešira, trebali biste nositi i rukavice kako biste zaštitili ruke. Korištenje kolotura može dovesti do raznih ozljeda, stoga je važno imati na umu ove mjere opreza prije korištenja kolotura. Evo nekih od najčešćih:
Koloturnici su važan dio opreme koji morate imati pri ruci kada podižete teške predmete. Koloturnici ne samo da smanjuju silu potrebnu za podizanje predmeta, već i smjer sile. Ovo je osobito važno ako podižete teške predmete, poput kosilice ili motocikla. Prije početka, važno je provjeriti može li sustav sidrenja izdržati punu težinu predmeta koji podižete.
Kada koristite sustav remenica, provjerite jesu li sidrišne točke primjerene za podnošenje opterećenja. Provjerite s proizvođačem remenice kako biste odredili težinu koju može sigurno podići. Ako je opterećenje preveliko, umjesto toga mogu se koristiti kompozitne remenice. Za vertikalna dizanja trebate koristiti set lančanika i nositi osobnu zaštitnu opremu. Sigurnosne mjere opreza pri korištenju remenica ključne su za zdravlje i sigurnost radnika.
