Yuav Ua Li Cas Linear Bearings Ua Haujlwm ? A linear bearing muaj xws li ib tug carriage thiab dov lub caij. Cov linear bearing yog mounted rau ntawm ib tug square los yog round tsheb ciav hlau nyob ntawm qhov yuav tsum tau ua ntawm daim ntawv thov. Rolling element ntawm lub bearing , txawm tias nws yog pob lossis cov menyuam swb, pab txav tau yooj yim.

Nyob rau hauv no hais txog, txoj kev qhia linear ua haujlwm li cas?

Cov Lus Qhia Linear yog block thiab tsheb ciav hlau system uas pab txhawb kev txav ntawm daim ntawv thov. Muaj ob qhov chaw rau lub Daim Ntawv Qhia Tawm System: ua Tawm Block thiab Linear Rail . Cov lus tsa suab yog tsim raws li tsheb ciav hlau los ntawm recirculating pob bearings nyob rau hauv lub block uas yog hu rau ntawm lub tsheb ciav hlau.

Dab tsi yog qhov preload ntawm cov kabmob linear? Preload yog kev tshem tawm ntawm internal clearance ntawm lub tsheb ciav hlau thiab carriage (los yog nruab nrab ntawm lub pob ntsia hlau thiab pob txiv ntoo). Qhov no ua rau lub kaw lus nruj dua los ntawm kev tsim cov khoom thauj ntawm lub kab tawm kev taw qhia (los yog pob ntsia hlau), uas txo qhov deflection thaum siv lub zog sab nraud.

Ib tug kuj yuav nug, hom kabmob twg yog siv rau kev tawm suab?

Linear tsab ntawv tsa suab yog qhov yooj yim tshaj plaws ntawm txhua qhov kev txav. Linear pob bearings muab kev txav mus rau hauv ib qho kev taw qhia. A cov menyuam bearing , nqa ib qho kev thauj khoom los ntawm kev tso cov khoom dov lossis cov yob ntawm ob lub nplhaib hu ua kev sib tw. Cov bearings no muaj ib lub nplhaib sab nraud thiab ob peb kab ntawm cov khoom khaws cia los ntawm tawb.

Yuav ua li cas koj preload bearings?

Preload tuaj yeem siv tau siv ob txoj hauv kev, khoom preload thiab caij nplooj ntoos hlav preload . Ib qho khoom preload yog tiav los ntawm tuav lub puab thiab sab rings ntawm lub bearing nyob rau hauv qhov chaw nrog spacers los yog xauv mechanisms thaum thov ib tug axial load.
