Bearings kese kam kartti hai
(1) Bearings or bearings are used to handle the parts of a rotating machine. This is such a
mechanical device jo masheen ke do ya adhik bhaagon ke beech kam se kam gharshan ke saath
saapeksh gati (rekheey gati ya ghoornan gati) kee suvidha pradaan karatee hai.
(2) dhuree ya takale (shaapht) ke us bhaag ko, jo beyaring par rakha jaata hai, jarnal (journal)
kaha jaata hai. jarnal, dhaaruk ke bheetar ghoomatee rahatee hai aur is prakaar ek to dhaaruk
dhuree ka bhaar aur doosare usapar daale hue balon ko sahan karatee hai tatha dhooree ko
bina kisee rukaavat ke ghoomane ka avasar detee hai.
(3) saral dhaaruk ek nalee ke samaan hota hai, jisamen dhuree ko daal diya jaata hai. parantu
tej chalanevaalee dhuriyon ke lie, ya jahaan gharshan ke kaaran dhaaruk tapakar kharaab ho
sakata ho, dhaaruk ke do paaton mein banaaya jaata hai jo vibhinn prakaar ke hote hain.kisee
masheen ka dhaaruk aisa bhaag hai jisapar masheen ke chalane se har samay bhaar rahata hai
(4) aur dhuree ke ghoomane ke kaaran dhaaruk kuchh na kuchh ghisata hee rahata hai. yadi
dhaaruk ko theek prakaar se na banaaya jae to bahut jald usako badalana padata hai. isalie sab
baaton ko dhyaan mein rakhate hue dhaaruk ko is prakaar banaana padata hai ki vah kam se
kam ghise tatha ghise hue bhaagon ko suvidha se badala ja sake. dhaaruk ke do bhaag hote
hain, ek bandhanee (brachkait) kahalaata hai,
(5) jo masheen mein kasa jaata hai aur is bandhanee ke bheetar dhaaruk ko jamaaya jaata hai,
jo peetal "gan" dhaatu (gun maital),ya kaanse ka hota hai. isee prakaar kee doosaree dhaatuen
bhee is bhaag ke banaane mein kaam aatee hain. isee bhaag ke bheetar dhuree ghoomatee hai.
