NEEDLE ROLLER BEARINGS K SERIES

 

Dab tsi yog K series koob rau cov menyuam bearings?

 

 

K series koob rau cov menyuam bearings yog tag nrho cov koob rau cov menyuam bearings tsis muaj puab nplhaib, uas yog ib hom radial koob rau cov menyuam bearings. Lawv lub npe ua raws li tus qauv code ntawm German INA (Schaeffler Group).

 

                                 productcate-526-327

Core qauv thiab nta

 

 

Tsis muaj lub nplhaib puab tsim

 

 Ncaj nraim siv cov ntawv xov xwm saum npoo raws li txoj kev sib tw (tus ncej yuav tsum tau ua kom tawv thiab hauv av rau Ra Tsawg dua lossis sib npaug rau 0.2μm).

 

 Txuag qhov chaw axial thiab tsim nyog rau cov xwm txheej uas tsis tshua muaj kev txwv radial installation qhov ntev

01

Ua kom tiav ntawm rab koob rollers

 Tsis muaj tawb, rab koob chais ua rau lub raceway, muab qhov siab tshaj plaws ntawm cov khoom dov.

 Qhov zoo: tsis tshua muaj siab radial load peev xwm (30% ~ 50% siab dua tib qhov loj me nrog lub tawb).

 Disadvantages: qis txwv ceev (vim muaj kev sib txhuam ntawm cov khoom dov).

02

Lub nplhaib sab nraud nrog ob sab tav

 Lub nplhaib sab nrauv muaj cov tav tav (flanges) ntawm ob sab rau axial positioning ntawm rab koob rollers.

 Qhov siab ntawm tav yog feem ntau Tsawg dua los yog sib npaug ntawm rab koob rau txoj kab uas hla, kom ntseeg tau tias tus qauv tsim

03

Kev txheeb xyuas cov lej zoo (siv INA K series ua piv txwv)

K AB × CD × EF
 AB: Inner diameter code (qhov tseeb puab txoj kab uas hla d=AB mm)
 CD: Sab nraud txoj kab uas hla D (mm)
 EF: Dav B (mm)
* Piv txwv: K 20 × 26 × 20 → d=20mm, D=26mm, B=20mm *

Core Zoo

 

 

Yam ntxwv

 

Piv txwv

 
Ultra{0}} muaj peev xwm thauj khoom siab Tag nrho cov koob txhaj tshuaj rau cov menyuam + lub taub me me rau cov menyuam tsim, lub peev xwm thauj khoom ib cheeb tsam nyob deb tshaj qhov sib sib zog nqus groove pob bearings
Ultra-thin radial seem Phab ntsa tuab tsuas yog 1 ~ 3 hli, haum rau qhov chaw nqaim (xws li qhov kawg me me ntawm cov pas nrig sib txuas, iav lub thawv vaj tsev)
Siab rigidity

Kab sib cuag quab yuam kis tau tus mob, me me deformation thiab kev txhawb nqa zoo.

 
Kev lag luam

Tsis muaj lub nplhaib sab hauv txo cov nqi tsim khoom, thiab siv cov ncej raws li kev sib tw yuav txuag cov khoom siv.

 

 

 

Tej yam kev thov scenarios

 Actuator hinges, nrov plig plawg mechanisms (cov ntaub ntawv tshwj xeeb / txheej yuav tsum tau)

 
 
 

 

 

Xaiv thiab installation cov ntsiab lus

 

1. Axis Requirements (Critical!)

Hardness: Ntau dua los yog sib npaug rau 58 HRC (hardened steel).

Roughness: Ra Tsawg dua lossis sib npaug ntawm 0.2 μm (daim iav hauv av).

Kev kam rau siab: k5 / m6 pom zoo (kev cuam tshuam haum kom ntseeg tau tias cov ncej raws li kev sib tw tsis fretting).

2. Cov Lus Qhia Kev Txhim Kho

Lub coaxiality ntawm lub ncej thiab cov kabmob lub tog zaum qhov yuav tsum tau ua kom ntseeg tau (kev ua yuam kev tsawg dua lossis sib npaug ntawm 0.05mm).

Ntxuav lub raceway ua ntej kev teeb tsa kom tsis txhob muaj cov khoom los ntawm nias rau hauv thiab ua rau tsis ua hauj lwm ntxov.

Siv cov txheej txheem kev teeb tsa txias (kub lub rooj zaum rau 80 ~ 100 degree), thiab tsis txhob rauj lub nplhaib sab nraud

3. Lubrication yuav tsum tau

Qhov nyiam lubrication yog siab siab lithium roj (NLGI Qib 2) los yog circulating roj.

Thawj qhov ntim ntim nyiaj rau 30% ~ 50% ntawm qhov chaw sab hauv thiab rov ua dua tsis tu ncua.

 

Hom kev ua tsis tiav thiab kev tiv thaiv

Qhov tshwm sim ua tsis tiav

 

Ua rau Analysis

 

Cov kev ceev faj

 

Ncej hnav thiab tsim kua muag

 

Ncej hardness tsis txaus / roughness tshaj tus qauv

 

nruj me ntsis tswj cov ncej ua kom zoo

 

Roller tawg

 

Installation qaij lossis overload cuam tshuam

 

Xyuas kom coaxiality thiab tsis txhob overloading

 

Flange tawg

 

Tshaj axial quab yuam (tsim taboo!)

 

Tsuas yog dais radial load, axial retaining nplhaib yog yuav tsum tau

 

Lubrication tsis ua hauj lwm sintering

 

Roj kom qhuav los yog muaj kab mob

 

Kev saib xyuas tsis tu ncua, kaw thiab plua plav
