Inkcazo eneenkcukacha zokusetyenziswa kwebherethi yebhola ekukhetheni izixhobo zombane zemoto

2.1 Ibheri kunye nomsebenzi wayo kwisakhiwo semoto

Izakhiwo zezixhobo zamandla eziqhelekileyo ziquka i-motor rotor (i-shaft, i-rotor core, i-winding), i-stator (i-stator core, i-stator winding, ibhokisi ye-junction, i-end cover, i-bearing cover, njl.njl.) kunye neendawo ezidibanisayo (i-bearing, i-seal, i-carbon brush, njl.njl.) kunye nezinye izinto eziphambili. Kuzo zonke iindawo zesakhiwo se-motor, ezinye ii-bear shaft kunye nomthwalo we-radial kodwa azinazo iintshukumo zazo zangaphakathi; Ezinye zentshukumo yazo yangaphakathi emva kodwa azithwali i-axis, umthwalo we-radial. Ii-bearing kuphela ezithwala zombini i-shaft kunye ne-radial load ngelixa zihamba ngokuhambelana ngaphakathi (ngokuthelekiswa ne-inner ring, i-outer ring kunye nomzimba ojikelezayo). Ke ngoko, i-bearing ngokwayo yinxalenye ebuthathaka yesakhiwo se-motor. Oku kukwamisela ukubaluleka koyilo lwee-bearing kwiimoto zoshishino.

Umzobo wohlalutyo lokubhola ngombane

2.2 Amanyathelo asisiseko oyilo lweebhereyitha eziqengqelekayo kwimoto

Uyilo lwee-rolling bearings kwii-electrical tool motors lubhekisa kwinkqubo yokubeka iintlobo ezahlukeneyo zee-bearings kwinkqubo kwi-shafting xa iinjineli ziyila ulwakhiwo lwee-electrical tool motors. Ukuze kufezekiswe ulungelelwaniso olufanelekileyo lwee-motor bearing, kuyimfuneko:

Inyathelo lokuqala: qonda imeko yokusebenza kweebheringi eziqengqelekayo kwizixhobo. Ezi ziquka:

- Imoto ethe tye okanye ethe nkqo

Umsebenzi wombane nge-electric drill, isarha yombane, i-electric pick, i-electric hammer kunye nezinye iintlobo ezahlukeneyo, kuqinisekisa i-motor kwimo yokufakela i-vertical kunye ne-horizontal bearing, ulwalathiso lwayo lomthwalo luya kwahluka. Kwii-motors ezithe tye, i-gravity iya kuba ngumthwalo we-radial, kwaye kwii-motors ezithe tye, i-gravity iya kuba ngumthwalo we-axial. Oku kuya kuchaphazela kakhulu ukhetho lohlobo lwe-bearing kunye noyilo lwe-bearing kwi-motor.

- Isantya esifunekayo semoto

Imfuneko yesantya semoto iya kuchaphazela ubungakanani bebheri kunye nokukhethwa kohlobo lwebheri, kunye noqwalaselo lwebheri kwimoto.

- Ukubalwa komthwalo oguquguqukayo othwalayo

Ngokwesantya semoto, amandla/i-torque elinganisiweyo kunye nezinye iiparameter, isalathiso (GB/T6391-2010/ISO 281 2007) sokubala umthwalo oguquguqukayo weebheringi zebhola, khetha ubungakanani obufanelekileyo beebheringi zebhola, umgangatho ochanekileyo njalo njalo.

- Ezinye iimfuno: ezifana neemfuno ze-axial channeling, ukungcangcazela, ingxolo, ukuthintela uthuli, umahluko kwizinto ezikwisakhelo, ukuthambekela kwemoto, njl.njl.

Ngamafutshane, ngaphambi kokuba uqale uyilo kunye nokukhetha iibheringi zeemoto zezixhobo zombane, kuyimfuneko ukuba ube nokuqonda okubanzi kweemeko zokusebenza zangempela zemoto, ukuze kuqinisekiswe ukuba ukhetho lwale yokugqibela lufanelekile kwaye lunokuthenjwa.

Inyathelo lesi-3: Chonga uhlobo lwebhereyitha.

Ngokwezinyathelo ezimbini zokuqala, kuqwalaselwa ulwakhiwo lwenkqubo yomthwalo weebheringi kunye nesakhiwo se-shaft yesiphelo esimiselweyo esikhethiweyo kunye nesiphelo esidadayo, emva koko kukhethwa iintlobo ezifanelekileyo zeebheringi zesiphelo esimiselweyo kunye nesiphelo esidadayo ngokweempawu zeebheringi.

3. Imizekelo yoyilo oluqhelekileyo lweebhereyitha zemoto

Kukho iintlobo ezininzi zoyilo lweebhereyitha zemoto. Ulwakhiwo lweebhereyitha zemoto olusetyenziswa rhoqo lunohlobo olwahlukeneyo lokufakelwa kunye nolwakhiwo. Oku kulandelayo kuthatha ulwakhiwo lweebhereyitha zebhola ezinzulu ezimbini njengomzekelo:

3.1 Isakhiwo sebhereyitha yebhola enzulu kabini

Isakhiwo se-double deep groove ball bearing sesona sakhiwo sixhaphakileyo se-shafting kwiimoto zoshishino, kwaye isakhiwo saso esiphambili senkxaso ye-shafting senziwe zii-deep groove ball bearing ezimbini. Ii-deep groove ball bearing ezimbini ziyadibana.

Njengoko kubonisiwe kumfanekiso ongezantsi:

Iprofayili yokuthwala

Kulo mfanekiso, i-shaft extension end bearing yi-positioning end bearing, kwaye i-non-shaft extension end bearing yi-floating end bearing. Iziphelo ezibini ze-bearing zithwele umthwalo we-radial kwi-shafting, ngelixa i-positioning end bearing (ekwi-shaft extension end kule sakhiwo) ithwele umthwalo we-axial we-shafting.

Ngokwesiqhelo ulungiselelo lwebheri yemoto yale sakhiwo lufanelekile ukuba umthwalo we-axial radial we-motor awukhulu. Okuqhelekileyo kukudibana komthwalo wesakhiwo se-micro motor.
