Tsarin Nada Bearing na Manufa na Gabaɗaya (Bearing na Rolling)

 

An raba shi zuwa: lambar da aka riga aka shigar, lambar asali da lambar gidan waya.

 

1. Sunan asali na lambar sirri

 

(Lambar rubutu, lambar girma, lambar diamita ta ciki [lambobi 2])

 

Ana amfani da lambar asali don nuna diamita na ciki, jerin diamita, jerin faɗi da nau'in bearing, gabaɗaya har zuwa lambobi biyar, kamar haka:

 

1) Diamita na ciki na bearing ana nuna shi ta lambar farko daga dama na lambar asali. Diamita na ciki na bearing tare da diamita na ciki na d=20~480mm gabaɗaya ninki ne na 5, kuma waɗannan lambobi biyu suna wakiltar ƙimar girman diamita na ciki na bearing da aka raba da 5, kamar 04 yana nufin d=20mm; 12 yana nufin d=60mm, da sauransu. Ga bearings masu diamita na ciki na 10mm, 12mm, 15mm da 17mm, lambobin diamita na ciki sune 00, 01, 02 da 03 bi da bi. Ga bearings masu diamita na ciki na ƙasa da 10mm da sama da 500mm, an ƙayyade hanyar bayyana diamita na ciki ta wata hanya, don Allah a koma zuwa GB/T272-93.

 

2) Jerin diamita na bearing (watau, jerin canje-canje a cikin diamita na waje da faɗin bearing tare da tsari iri ɗaya da diamita na ciki iri ɗaya) an nuna shi ta lamba ta uku daga dama na lambar asali. Misali, ga bearings na radial da radial, 0 da 1 suna nuna ƙarin jerin haske; 2 yana nuna jerin haske; 3 yana nuna jerin matsakaici; 4 yana nuna jerin nauyi. Kwatanta girman tsakanin jerin an nuna shi a cikin hoton da ke ƙasa. Bearings na thrust banda 1 don wakiltar jerin haske, sauran da bearings na radial iri ɗaya ne.

 

3) Jerin faɗin bearing (watau, jerin canje-canje a faɗin bearing mai tsari iri ɗaya, diamita na ciki da diamita jerin) ana nuna su ta hanyar lamba ta huɗu daga dama na lambar asali. Lokacin da aka lissafa kwatancen jerin diamita na jerin faɗin a cikin Hoto na 13-4 a matsayin jerin 0 (jerin al'ada), ba za a iya yiwa lambar jerin faɗin O alama a cikin lambar don yawancin bearings ba, amma ga bearings na birgima mai zagaye da bearings na birgima mai tapered, ya kamata a yiwa lambar jerin faɗin 0 alama.

 

Ana kiran lambobin jerin diamita da lambobin jerin faɗi gaba ɗaya a matsayin lambobin jerin girma.

 

4) Lambar nau'in bearing tana wakiltar lamba ta biyar daga dama na lambar asali (ga bearings na birgima masu silinda da bearings na birgima masu silinda, lambar harafi ce).

 

2. Lambar gidan waya

 

Lambar akwatin gidan waya (post-code) ita ce amfani da haruffa da lambobi don nuna tsari, haƙuri da buƙatun musamman na kayan. Akwai abubuwa da yawa da ke cikin lambobin gidan waya, kuma ga wasu sunayen lambobin da aka saba amfani da su.

 

1) Lambar tsarin ciki ita ce ta nuna tsarin ciki daban-daban na irin wannan nau'in bearing, wanda aka nuna ta hanyar haruffa sannan lambar asali ta biyo baya. Misali, bearings na ƙwallon hulɗa mai kusurwa tare da kusurwoyin hulɗa na 15°, 25° da 40° ana wakilta su da C, AC da B don wakiltar bambancin tsarin ciki.

 

2) An raba matakin haƙuri na bearing zuwa maki 2, maki 4, maki 5, maki 6, maki 6X da maki 0, jimilla maki 6, daga sama zuwa ƙasa, kuma lambobinsu sune /PZ, /P4, /PS, /P6, /P6X da /PO. Daga cikin azuzuwan haƙuri, aji 6X yana aiki ne kawai ga bearings masu tauri; Mataki na 0 aji ne na yau da kullun, wanda ba a yiwa alama a cikin lambar bearing ɗin ƙafafun ba.

 

3) Jerin bearing radial clearance da aka saba amfani da shi an raba shi zuwa rukuni 1, ƙungiyoyi 2, ƙungiyoyi 0, ƙungiyoyi 3, ƙungiyoyi 4 da ƙungiyoyi 5, jimillar ƙungiyoyi 6, kuma radial clearance daga ƙanana zuwa babba ne. Rukunin o clearance rukuni ne da aka saba amfani da shi, wanda ba a yiwa alama a cikin lambar bearing ba, kuma sauran ƙungiyoyin clearance ana wakilta su da /CI, /CZ, /C3, /C4 da /CS a cikin lambar bearing.

 

3. Lambar kafin lokaci

 

Ana amfani da sunan farko na bearing don nuna ƙananan sassan bearing, waɗanda aka nuna ta haruffa. Misali, ana amfani da L don wakiltar zoben da za a iya rabawa na bearing ɗin da za a iya rabawa; K yana nuna abubuwan birgima da sassan keji na bearing ɗin, da sauransu.

 

Akwai nau'ikan bearings masu birgima da yawa a aikace-aikace na aiki, kuma lambobin bearings masu dacewa suma sun fi rikitarwa. Lambar da aka gabatar a sama ita ce mafi sauƙi kuma mafi yawan amfani da ita a cikin lambar bearings, kuma za ku iya gano da kuma duba bearings da aka saba amfani da su idan kun saba da wannan ɓangaren na lambar. Don cikakken hanyar lambar bearings masu birgima, da fatan za a duba GBT272-93.
