An yi cikakken nazari kan halaye da amfani da nau'ikan bearings guda 14

Bearing muhimmin sashi ne a cikin kayan aikin injiniya, babban aikin shine tallafawa jikin da ke juyawa, rage yawan gogayya a cikin tsarin watsawa. Dangane da hanyoyin rarrabuwa daban-daban, ana iya raba bearing zuwa nau'ikan da yawa. Ga halaye, bambance-bambance da amfani da bearing guda 14 gama gari:

1. Hulɗar kusurwa Ƙwallon ƙwallo
Siffofi: Akwai kusurwar hulɗa tsakanin zobe da ƙwallon, kusurwar hulɗa ta yau da kullun ita ce 15°, 30° da 40°, girman kusurwar hulɗa, girman ƙarfin ɗaukar nauyin axial, ƙaramin kusurwar hulɗa, mafi dacewa ga juyawa mai sauri. Bearing na layi ɗaya zai iya jure nauyin radial da nauyin axial na unidirectional.

Aikace-aikace: ginshiƙi ɗaya don sandar kayan aikin injin, injin mai yawan mita, injin turbin gas, da sauransu. Layi biyu don famfon mai, injin hura tushen, da sauransu.

2. Daidaita bearing ɗin ƙwallon
Siffofi: Layuka biyu na ƙwallon ƙarfe, hanyar tsere ta waje nau'in zagaye ne na ciki, wanda zai iya daidaita kuskuren axis ta atomatik sakamakon karkacewar shaft ko zuciyar daban-daban ta harsashi. Ana iya ɗora bearings masu tauri a kan shaft cikin sauƙi ta hanyar amfani da manne kuma galibi suna ɗaukar nauyin radial.

Amfani: Injinan aikin katako, shaft ɗin injinan yadi, bearing mai daidaitawa a tsaye tare da kujera, da sauransu.

3. Daidaita kai ɗaurin nadi
Siffofi: Akwai na'urori masu zagaye tsakanin zoben waje na hanyar tsere mai zagaye da zoben ciki na hanyar tsere mai zagaye biyu, waɗanda aka raba zuwa nau'ikan R, RH, RHA da SR guda huɗu bisa ga tsarin ciki. Saboda cibiyar zagaye ta zoben waje ta yi daidai da cibiyar ɗaukar kaya, tana da aikin daidaitawa, kuma tana iya daidaita kuskuren axis ta atomatik wanda karkacewar shaft ko gidan ko cibiyoyin daban-daban suka haifar, kuma tana iya jure nauyin radial da nauyin axial mai hanyoyi biyu.

Amfani: Injinan yin takarda, na'urar rage gudu, aksali na motocin jirgin ƙasa, da sauransu.

4. Tura mai ɗaukar nauyin nadi mai daidaita kansa
Siffofi: Tsarin nadi mai karkata zuwa siffar zobe, saman hanyar tsere ta wurin zama mai siffar zobe ne, tare da daidaita aikin, yana ba da damar shaft ɗin ya sami yawan karkata, ƙarfin ɗaukar nauyin axial yana da girma sosai, a cikin nauyin axial kuma yana iya jure wa wasu nauyin radial.

Aikace-aikace: janareta na ruwa, injin tsaye, da sauransu.

5. Bearing mai tauri
Siffofi: An sanya masa abin naɗin tebur mai zagaye, kuma ana shirya masa abin naɗin ta hanyar babban gefen tsaro na zobe na ciki, ƙirar tana sa saman hanyar tseren zobe na ciki, saman hanyar tseren zobe na waje da mazugi na saman birgima na naɗin ya haɗu a wani wuri a kan layin tsakiyar bearing. Bearing na layi ɗaya zai iya ɗaukar nauyin radial da nauyin axial na unidirectional, bearing na layi biyu zai iya ɗaukar nauyin radial da nauyin axial na bidirectional.

Aikace-aikace: ƙafafun gaba na mota, ƙafafun baya, na'urar watsawa, da sauransu.

6. Ƙwallon da ke ɗauke da zurfin rami
Siffofi: Kowace zobe ta ƙwallon zurfin ramin da ke kan tsarin tana da hanyar tsere mai ci gaba da ragowa tare da sashe na kusan kashi ɗaya bisa uku na kewayen ƙwallon da ke kewaye da ita. Ana amfani da ita galibi don ɗaukar nauyin radial, kuma tana iya ɗaukar wani nau'in nauyin axial. Lokacin da radial clearance na bearing ya ƙaru, yana da ikon ɗaukar nauyin ƙwallon lamba mai kusurwa kuma yana iya jure nauyin axial yana juyawa a hanyoyi biyu.

Aikace-aikace: mota, tarakta, kayan aikin injin, da sauransu.

7. Ɗaukar ƙwallon da aka tura
Siffofi: An yi shi da zoben tseren gasket mai siffar tseren tsere da kuma haɗa ƙwallon da keji. Zoben tseren da aka daidaita da sandar ana kiransa zoben shaft, kuma zoben tseren da aka daidaita da harsashi ana kiransa zoben wurin zama. Ana daidaita bearings masu siffar hanyoyi biyu da sandar sirri ta zoben tsakiya, bearings masu siffar hanyoyi ɗaya na iya jure nauyin axial mai siffar hanyoyi ɗaya, kuma bearings masu siffar hanyoyi biyu na iya jure nauyin axial mai siffar hanyoyi biyu (dukansu ba za su iya jure nauyin radial ba).

Aikace-aikace: fil ɗin sitiyarin mota, sandar kayan aikin injin, da sauransu.

8. Ƙarfin abin nadi mai ƙarfi
Siffofi: Ana amfani da shi don ɗaukar nauyin axial na babban shaft, haɗin nauyin, amma nauyin tsayin daka bai kamata ya wuce kashi 55% na nauyin axial ba. Idan aka kwatanta da sauran bearings na ture roller, wannan nau'in bearing yana da ƙarancin abin da ke haifar da gogayya, saurin gudu mafi girma da ikon daidaitawa. Na'urar na ...

Amfani: janareta na hydraulic, ƙugiya mai crane, da sauransu.

9. Bearing mai siffar silinda
Siffofi: Yawanci ana shirya na'urar jujjuyawar silinda ta hanyar gefuna biyu na zoben ɗaukar nauyi, kuma na'urar jujjuyawar keji da zoben jagora suna haɗuwa, wanda za a iya raba shi da sauran zoben ɗaukar nauyi kuma ya kasance cikin bearing ɗin da za a iya rabawa. Shigarwa da warwarewa sun fi dacewa, musamman lokacin da ake buƙatar zoben ciki da na waje su dace da shaft da gidan. Irin waɗannan bearings galibi ana amfani da su ne kawai don ɗaukar nauyin radial, kuma bearings masu layi ɗaya kawai tare da zoben ciki da na waje da masu gadi za su iya ɗaukar ƙananan kaya na axial akai-akai ko manyan kaya na axial masu tsaka-tsaki.

Amfani: babban injin, sandar kayan aikin injin, da sauransu.
