Tshaj li ntawm Jargon: Nkag siab qhov loj me thiab qhov ntev tances rau hauv dov bearings

Thaum xaiv thiab txhim khodov bearings,ob lub ntsiab lus technical feem ntau tshwm sim ntawm engineering kos duab:Basic DimensionthiabDimensional kam rau ua. Tej zaum lawv yuav zoo li cov lus tshwj xeeb, tab sis kev nkag siab lawv yog qhov tseem ceeb rau kev ua tiav kev sib dhos, ua kom ruaj khov, thiab txuas ntxiv mus.bearing kev pabcuam lub neej.

Qhov Basic Dimension yog dab tsi?

CovBasic Dimensionyog covtheoretical lojtau teev nyob rau ntawm ib qho kev tsim qauv kos duab - qhov tseem ceeb ntawm qhov "zoo tagnrho" loj rau ib feem. Hauv rolling bearings, qhov no suav nrog:

• Inner Diameter (d):Qhov siab tshaj plaws radial dimension ntawm cov kabmob lub nplhaib puab. Rau qhov sib sib zog nqus groove pob bearings, lub puab txoj kab uas hla code × 5 = tiag inner inch (thaum ≥ 20 mm; piv txwv li, code 04 txhais tau tias d = 20 mm). Qhov ntau thiab tsawg hauv qab 20 hli ua raws li cov lej ruaj khov (piv txwv li, code 00 = 10 mm). Sab hauv txoj kab uas hla ncaj qha cuam tshuam rau radial load peev.

• Sab nraud txoj kab uas hla (D):Qhov tsawg kawg nkaus radial dimension ntawm lub nplhaib sab nrauv, cuam tshuam lub peev xwm thauj khoom thiab qhov chaw teeb tsa.

• Dav (B):Rau radial bearings, dav cuam tshuam lub peev xwm thiab rigidity.

• Qhov siab (T):Rau thrust bearings, qhov siab influences load peev thiab torque kuj.

• Chamfer (r):Ib qho me me nkhaus lossis beveled ntug uas ua kom muaj kev ruaj ntseg thiab tiv thaiv kev ntxhov siab.

Cov txiaj ntsig theoretical no yog qhov pib tsim. Txawm li cas los xij, vim cov txheej txheem tsim khoom,zoo meej qhov tseeb yog yuav luag tsis yooj yim sua kom ua tiav-thiab qhov ntawd yog qhov uas kam rau ua.

Dimensional Tolerance yog dab tsi?

Dimensional kam rau uayog covtso cai sib txawvnyob rau hauv bearing loj thiab rotation raug los ntawm qhov yooj yim dimension thaum lub sij hawm tsim khoom.

Formula:Dimensional tolerance = Upper deviation – qis deviation

Piv txwv li: Yog hais tias ib tug bearing bore yog 50.00 hli nrog ib tug pub ntau yam ntawm +0.02 hli / −0.01 hli, qhov kam rau ua yog 0.03 hli.

Tolerances yog txhais los ntawm cov qib precision. Cov qib siab dua txhais tau tias kev ua siab ntev dua.

International Standards for Bearing Tolerances

ISO Standard Qib:

• P0 (Normal):Standard precision for general industrial siv.

• P6:Siab precision rau high-speed los yog nruab nrab-load daim ntaub ntawv.

• P5 / P4:High precision rau tshuab cuab tam spindles los yog precision machinery.

• P2:Ultra-siab precision rau cov twj paj nruag thiab aerospace kev siv.

ABEC (ABMA) Qib:

• ABEC 1 / 3: Automotivethiab davkev lag luamsiv.

• ABEC 5/7/9:High-speed, high-precision daim ntaub ntawv xws li CNC spindles thiab aerospace seev.

Vim li cas qhov no tseem ceeb rau koj txoj kev lag luam

Xaiv txoj caiyooj yim dimensionthiabqib toleranceNws yog ib qho tseem ceeb los xyuas kom meej qhov zoo ntawm bearing kev ua tau zoo, tsis txhob hnav ntxov ntxov, thiab tiv thaiv tus nqi poob qis. Kev sib xyaw ua ke kom raug:

• Perfect haum nrog shafts thiab vaj tse

• Kev ua haujlwm siab ceev ruaj khov

• Txo kev vibration thiab suab nrov

• Lub neej ua haujlwm ntev dua
