Kufananidza kutenderera mabhengi uye plain bearings

Zvekushandisama bearings, iyo friction properties yekukwira mabearings inogona kupatsanurwa kuita rolling bearings uye sliding bearings, tinogona kusarudza marudzi akasiyana-siyana ekutakura zvichienderana nezvinodiwa zvekushandisa, rolling bearings uye sliding bearings ane maitiro akasiyana ekushandiswa,

Zvinhu zvikuru zverolling bearingsvari:

1. Diki friction damping (zvinei neasiri-liquid friction sliding bearing), flexible start-up;

2. Inogona kutakura radial uye axial mitoro panguva imwe chete, kurerutsa chimiro chekutsigira;

3. Kucheneswa kweradial idiki, uye kubvumidzwa kunogonawo kubviswa ne preloading nzira, saka kutenderera kunenge kwakakwirira;

4. Kuchinjana kwakanaka uye kugadzirisa nyore.

 

Zvinhu zvikuru zveplain bearingsvari:

1. Basa rakagadzikana uye pasina ruzha;

2. High kutenderera kwakarurama;

3. Diki friction kurasikirwa panguva yemafuta ekuzora;

4. Diki radial size;

5. High kutakura simba.

 

Ndeapi mabhenefiti neakaipa ekutenderedza mabhengi kana achienzaniswa neaka plain bearings? Kuongorora kunotevera:

 

Kuenzaniswa nemabhengi akajeka, rolling bearings ine zvinotevera zvakanakira:

1. Iko friction coefficient ye rolling bearings iduku kudarika iyo inotsvedza mabheji, uye kubudirira kwekufambisa kwakakwirira. Kazhinji, friction coefficient of sliding bearings ndeye 0.08-0.12, nepo friction coefficient ye rolling bearings inongova 0.001-0.005;

2. Rolling bearings dzave dzakamira, serialized uye generalized, dzakakodzera kugadzirwa kwemazhinji uye kupa, uye zviri nyore kushandisa nekuchengetedza;

3. Rolling bearings yakagadzirwa nesimbi inotakura uye inogadziriswa kupisa kupisa, saka mabheji anoputika haana kungova nehupamhi hwemagetsi ehupenyu uye hupenyu hurefu hwebasa, asi zvakare anogona kuchengetedza simbi inodhura isina-ferrous inoshandiswa mukugadzira sliding bearings;

4. Kusununguka kwemukati kwekutakura kuduku kuduku, uye machining akarurama echikamu chimwe nechimwe chakakwirira, saka kururamisa kwekumhanya kwakakwirira. Panguva imwecheteyo, kuoma kwekutakura kunogona kuwedzerwa nekutanga kurodha. Izvi zvakakosha zvikuru kumichina chaiyo;

5. Mamwe mabheji anoputika anogona kutakura radial load uye axial load panguva imwe chete, saka chimiro chekutakura chinotakura chinogona kurerutswa;

6. Nekuda kwehukuru hwekutapurirana uye kuderera kwekupisa chizvarwa chekutenderedza mabheji, kushandiswa kwemafuta ekuzora kunogona kuderedzwa, uye kukwirisa uye kugadzirisa zviri nyore;

7. Rolling bearings inogona kushandiswa nyore nyore kune uranium mune chero nzira yenzvimbo.

 

 

Nekudaro, zvese zvakakamurwa kuita maviri, uye rolling bearings zvakare ine zvimwe zvipingamupinyi, izvo zvikuru ndezvi:

1. Kuremerwa kwekutakura kwekutakura mabheji kuduku zvikuru kudarika kutsvedza kwevhoriyamu imwechete, saka, radial size ye rolling bearings yakakura. Naizvozvo, muchiitiko chekutakura mutoro muhombe uye chiitiko chinoda diki radial saizi uye compact chimiro (senge yemukati combustion injini crankshaft kutakura), inotsvedza mabheji anonyanya kushandiswa;

2. Kudengenyeka uye ruzha rwemabheji ekutenderera zvakakura, kunyanya muchikamu chekupedzisira chekushandiswa, saka, kana izvo zvinodiwa zvakanyatsonaka zvakanyanya uye kuzununguka kusingabvumirwi, mabheji ekukunguruka anonetsa kuve anokwanisa, uye mhedzisiro yekutsvedza mabheji. kazhinji zviri nani;

3. Rolling bearings inonyanya kunzwisiswa kune dzimwe nyika dzakadai sesimbi machipisi, uye kana zvinhu zvekunze zvangopinda muberengi, zvinoburitsa kutenderera kwakakura kudengenyeka uye ruzha, izvo zvinokonzeresa kukuvara kwekutanga. Mukuwedzera, mabheji ekutenderera anogonawo kukanganisa kukuvara kwekutanga nekuda kwesimbi inclusions. Kunyangwe kana kukuvara kwekutanga kukasaitika, kune muganho kune hupenyu hwekukunguruka mabheji. Muchidimbu, mabearings ane hupenyu hupfupi hwesevhisi pane plain bearings.

 

Kuenzaniswa nemabhengi ekutenderera uye kutsvedza mabhengi, imwe neimwe ine zvayakanakira nezvayakaipira, uye imwe neimwe inotora imwe chiitiko chinoshanda, saka, izvo zviviri hazvigone kutsivana zvachose, uye imwe neimwe inokura mune imwe nzira uye inowedzera munda wayo. Nekudaro, nekuda kwemabhenefiti akatanhamara ekutenderedza mabheji, pane katsika kekuti vanononoka kukunda. Parizvino, rolling bearings dzakagadziridzwa kuita mhando huru yetsigiro yemakina, uye anowedzera uye anoshandiswa zvakanyanya.
