Izinhlobo zama-bearings alula

 

Igebe phakathi komgodi kanyeibhereithintana nobuso, okubizwa ngokuthi i-plain bearing. Isetshenziswa kabanzi ngoba iwukuxhumana kobuso okungamelana namandla amakhulu angaphandle, ayimelani nokushaqeka, futhi inesakhiwo esilula. Isibonelo, amalunga ashukumayo esandla se-Excavator's Monster Hand.

 

Amabheringi ashelelayoingahlukaniswa ngezinhlobo ezintathu ngokuya ngesiqondiso samandla, okungukuthi:

 

1. Ukuthwala okushelelayo okusabalalayo

Isiqondiso samandla sama-radial plain bearings siqonde ngqo ku-axis ephakathi, esingahlukaniswa ngezinhlobo ezintathu ngokwesimo:

 

1) Ukuthwala Okuhlanganisiwe: Ukuthwala Okuhlanganisiwe kuyibhere elijwayelekile elihlanganisiwe elishelelayo, elixhunywe nohlaka ngamabhawodi. Ingcindezi yangaphakathi yembobo yesihlalo sokuthwala, indebe kawoyela ifakiwe phezulu kwendlu yokuthwala, imbobo yokungena kawoyela isesikhwameni somgodi, kanti ubuso bangaphakathi bugcwele ibhereyi (noma isikhwameni somgodi) esenziwe ngezinto zokulwa nokungqubuzana ukuvula umsele kawoyela we-axial ukuze kusatshalaliswe ukugcotshwa kukawoyela okugcobayo

 

2) Ukuthwala okufanayo: Lolu hlobo lokuthwala kulula kakhulu ukulufaka nokuyiqaqa, futhi intengo iphansi, futhi lusetshenziswa kabanzi ngomshini. Isibonelo, amabheringi kuma-crank ezinhlobo ezahlukene zezinjini zomlilo zangaphakathi

 

3) Ukuthwala izingxenye ezine: okwaziwa nangokuthi ukuthwala izingxenye ezine, okusetshenziswa ezimotweni ezinkulu, njengezinjini zokudlidliza, izinjini zokudlidliza kanye nezinye izimbobo ze-spindle.

 

Izinto zokwakha ama-bearing alula ikakhulukazi ziyinsimbi ephonswe kanye nensimbi ephonswe. Ngenxa yokuthungwa okuqinile, kulula ukubangela ukuguguleka kwejenali, ngakho-ke i-bushing ivame ukungezwa phakathi kwe-shaft kanye ne-bearing. Izinto zokwakha zale bushing ikakhulukazi ziyithusi, i-alloy emhlophe kanye ne-barbit alloy.

 

2. Ukuthwala okushelelayo

 

Umthwalo we-plain thrust bearing uhambisana nesiqondiso se-axial, esingagcini nje ngokusekela ukujikeleza kwendlela, kodwa futhi sivimbela ukunyakaza eduze kwe-axis. Ungahlukaniswa ngezinhlobo ezine:

 

1) I-ring thrust bearing: ihlukaniswe kanje:

 

(1) Ukuthwala kwe-single-ring thrust: Ukuthwala kwe-single-ring thrust, okungamelana nokubethela kwe-axial kuzo zombili izinhlangothi.

 

(2) Ukuthwala kwe-Multi-ring thrust: Lolu hlobo lwe-shaft lungathwala i-axial thrust kuzo zombili izinhlangothi, isivinini esikhulu kanye nomthwalo osindayo.

 

2) I-Class bearing: eyaziwa nangokuthi i-pivot bearing, iyi-sliding thrust bearing efakwe ekugcineni kwe-shaft, ngakho-ke ibizwa nangokuthi i-base column thrust bearing.

 

3) I-Hydrodynamic lubrication thrust bearing: ubuso bokungqubuzana phakathi kwe-shaft kanye ne-bearing benziwa bube ubuso obuthambekele noma ibhlogo elithambekele. Kukhiwa ungqimba lwamafutha e-hydrodynamic endaweni ngayinye ethambekele noma ibhloko elithambekele ukuze i-shaft ingathintani ne-bearing.

 

4) Ukuthwala Okungaguquki: Uma umthwalo weyunithi yebhereyitha mkhulu kakhulu, akunakwenzeka ukusungula ifilimu kawoyela ngokuqala okungaguquki, ngakho-ke ukuthwala okungaguquki kumele kusetshenziswe. Uketshezi (uwoyela) lucindezelwa yiphampu futhi luthunyelwa phakathi kwezingxenye ezimbili ukuze kulondolozwe ukugcotshwa ngesikhathi sokusebenza. Ngenxa yokuthi uketshezi luhlinzekwa yizwe langaphandle, lubizwa nangokuthi ukuthwala kwengcindezi yangaphandle. Uma ukucindezela kukawoyela wephampu kushintshwa kube ukucindezela komoya, kubizwa ngokuthi ukuthwala kwemoya okungaguquki.

 

3. Amabheringi akhethekile ashelelayo

 

1) Ukuthwala okunezimbobo: okwaziwa nangokuthi ukuthwala okufakwe uwoyela, kuqhekeka ngendlela yokuqhekeka kwensimbi yempuphu. Ngokuvamile kufanelekile kuma-radial bearings anemithwalo elula.

 

2)Ama-bearings angenawo uwoyela: anokumelana okuhle kakhulu nokuguguleka, afanelekela imishini yokucubungula ukudla elula kanye nemishini engangcolisi ukungcola, njenge-Nelong bearings.
