Standard qhov chaw thiab feem ntau

Standard qhov chaw: Cov qauv daim ntawv, qhov loj me, nto zoo thiab sawv cev txoj kev tau raug standardized.Piv txwv li, threaded fasteners, cov yuam sij, pins, dov bearings thiab springs, thiab lwm yam. Cov khoom siv tau dav siv thiab tsim los ntawm cov chaw ua haujlwm tshaj lij.Cov khoom siv feem ntau: Cov qauv duab thiab qhov loj ntawm qee qhov chaw muaj kev sib koom ua ke, thiab cov khoom uas muaj ib txoj kev kos duab tshwj xeeb hauv kev kos duab, xws li iav, splines, vuam qhov chaw, thiab lwm yam.

Kev kos duab ntawm threaded fastener kev sib txuas Cov txheej txheem kos duab: (1) Kos ib txoj kab tuab ntawm qhov sib cuag ntawm ob qhov chaw, thiab kos ob kab tuab tuab ntawm qhov tsis sib cuag. (los yog kab symmetrical) ntawm cov khoom seem lossis cov qauv (bolts, txiv ntseej, ntxhua khaub ncaws, thiab lwm yam), cov khoom no tau kos yam tsis muaj kev txiav, uas yog, lawv cov qauv tseem raug kos.(3) Hauv seem saib, cov kab lus ntawm ob qhov chaw nyob rau hauv kev sib cuag nrog ib leeg yuav tsum yog opposite nyob rau hauv cov kev taw qhia los yog nyob rau hauv sib txawv intervalS tib ib feem nyob rau hauv txhua seem saib, seem kab kev taw qhia thiab qhov sib nrug yuav tsum yog tib yam.

Cov cim tseem ceebCov cim ntawm tus yuam sij muaj peb ntu: tus lej qauv, lub npe, hom thiab qhov loj me.Piv txwv li, A hom A (lub taub hau puag ncig) zoo tib yam tiaj tus yuam sij, b = 12mm, h = 8mm, L = 50 mm, uas yog cim : GB / T 1096 qhov tseem ceeb 12 x 8 x 50 Nws yog cim raws li: piv txwv li, hom c (ib puag ncig lub taub hau) zoo tib yam tiaj tus yuam sij, b = 18mm, h = 11mm, L = 100 mmGB / T 1096 C 18 × 11 × 100The "A" lo lus ntawm hom A tus yuam sij hauv lub cim raug tshem tawm, thiab hom B thiab hom C yuav tsum tau cim nrog "B" thiab "C".

Parameters ntawm cylindrical helical compression springs 1.Hlau txoj kab uas hla d: txoj kab uas hla ntawm hlau winding caij nplooj ntoos hlav.2, lub puab kab D, txheej txoj kab uas hla D thiab nruab nrab txoj kab uas hla D ntawm lub caij nplooj ntoos hlav, txoj kab uas hla ntawm lub puab nplhaib ntawm lub caij nplooj ntoos hlav hu ua sab hauv txoj kab uas hla, txoj kab uas hla ntawm lub nplhaib sab nrauv ntawm lub caij nplooj ntoos hlav hu ua sab nraud txoj kab uas hla, thiab qhov nruab nrab tus nqi ntawm sab hauv thiab sab nraud txoj kab uas hla ntawm lub caij nplooj ntoos hlav yog hu ua nruab nrab txoj kab uas hla, D, = (D + D,) 12.3.Pitch t ntawm lub caij nplooj ntoos hlav: Lub axial nrug ntawm txoj kab nruab nrab ntawm ntu ntawm ob lub nplhaib uas nyob ib sab, tshwj tsis yog rau lub nplhaib txhawb nqa ntawm ob qho kawg.
