Kufotokozera mwatsatanetsatane kwa momwe mpira umagwiritsidwira ntchito posankha injini ya zida zamagetsi

2.1 Bearing ndi ntchito yake mu kapangidwe ka injini

Kapangidwe ka zida zamagetsi zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo rotor ya mota (shaft, rotor core, winding), stator (stator core, stator winding, junction box, end cover, bearing cover, etc.) ndi zigawo zolumikizira (bearing, seal, carbon burashi, etc.) ndi zigawo zina zazikulu. M'zigawo zonse za kapangidwe ka mota, pali bear shaft ndi radial load koma sizimayenda mkati mwake; Zina mwa kayendedwe kawo kamkati koma sizimanyamula axis, radial load. Ma bearing okha ndi omwe amanyamula shaft ndi radial load pamene akuyenda mozungulira mkati (mofanana ndi mphete yamkati, mphete yakunja ndi thupi lozungulira). Chifukwa chake, bearing yokha ndi gawo lofunika kwambiri la kapangidwe ka mota. Izi zimatsimikiziranso kufunika kwa bearing layout mu ma industrial motors.

Chithunzi chowunikira kubowola kwa magetsi

2.2 Masitepe oyambira okonzera ma bearing mu mota

Kapangidwe ka mabearing ozungulira mu ma mota a zida zamagetsi kumatanthauza njira yoyika mitundu yosiyanasiyana ya mabearing mu dongosolo mu shafting pamene mainjiniya akupanga kapangidwe ka ma mota a zida zamagetsi. Kuti mukwaniritse dongosolo loyenera la bearing ya mota, ndikofunikira:

Gawo loyamba: kumvetsetsa momwe mabearing ozungulira amagwirira ntchito. Izi zikuphatikizapo:

- Injini yopingasa kapena yoyimirira

Kugwira ntchito kwamagetsi pogwiritsa ntchito kubowola kwamagetsi, sosi yamagetsi, choko chamagetsi, nyundo yamagetsi ndi mitundu ina yosiyanasiyana, kutsimikizira injiniyo mu mawonekedwe oyika bearing yoyima ndi yopingasa, njira yake yolemerera idzakhala yosiyana. Kwa ma mota opingasa, mphamvu yokoka idzakhala katundu wozungulira, ndipo kwa ma mota opingasa, mphamvu yokoka idzakhala katundu wozungulira. Izi zidzakhudza kwambiri kusankha mtundu wa bearing ndi kapangidwe ka bearing mu injiniyo.

- Liwiro lofunikira la injini

Kufunika kwa liwiro la mota kudzakhudza kukula kwa bearing ndi kusankha mtundu wa bearing, komanso kasinthidwe ka bearing mu mota.

- Kuwerengera katundu wamphamvu wonyamula

Malinga ndi liwiro la injini, mphamvu/torque yoyesedwa ndi magawo ena, reference (GB/T6391-2010/ISO 281 2007) kuti muwerengere katundu wosinthasintha wa ma bearing a mpira, sankhani kukula koyenera kwa ma bearing a mpira, grade yolondola ndi zina zotero.

- Zofunikira zina: monga zofunikira pa axial channeling, kugwedezeka, phokoso, kupewa fumbi, kusiyana kwa zinthu za chimango, kupendekeka kwa mota, ndi zina zotero.

Mwachidule, musanayambe kupanga ndi kusankha ma bearing a injini ya zida zamagetsi, ndikofunikira kumvetsetsa bwino momwe injiniyo imagwirira ntchito, kuti muwonetsetse kuti yasankhidwa moyenera komanso modalirika.

Gawo 3: Dziwani mtundu wa bere.

Malinga ndi magawo awiri oyamba, kapangidwe ka dongosolo la kuberekera ndi shaft ya malekezero osankhidwa okhazikika ndi malekezero oyandama amaganiziridwa, kenako mitundu yoyenera ya kuberekera imasankhidwa ya malekezero okhazikika ndi malekezero oyandama malinga ndi makhalidwe a kuberekera.

3. Zitsanzo za kapangidwe kabwino ka injini

Pali mitundu yambiri ya kapangidwe ka ma bearing a mota. Kapangidwe ka ma bearing a mota komwe kamagwiritsidwa ntchito kwambiri kali ndi mitundu yosiyanasiyana ya ma installation ndi ma structure. Chitsanzo cha izi ndi kapangidwe ka ma bearing a mpira woonekera bwino kwambiri wa double deep groove ball:

3.1 Kapangidwe ka mpira wokulirapo kawiri

Kapangidwe ka double deep groove ball bearing ndi kapangidwe kofala kwambiri ka shafting mu ma industrial motors, ndipo kapangidwe kake ka shafting support kamapangidwa ndi ma deep groove ball bearing awiri. Ma deep groove ball bearing awiri amalumikizana.

Monga momwe chithunzi chili pansipa chikusonyezera:

Mbiri yonyamula

Mu chithunzichi, chogwirira cha shaft extension end bearing ndi chogwirira cha positioning end bearing, ndipo chogwirira cha non-shaft extension end bearing ndi chogwirira cha floating end bearing. Malekezero awiri a chogwiriracho ali ndi katundu wa radial pa shafting, pomwe chogwirira cha positioning end bearing (chomwe chili kumapeto kwa shaft extension mu kapangidwe kameneka) chili ndi katundu wa axial wa shafting.

Kawirikawiri dongosolo la mabearing a injini la kapangidwe kameneka ndi loyenera chifukwa cha kulemera kwa ma radial axial a motor komwe sikuli kwakukulu. Chofala kwambiri ndi kulumikizana kwa katundu wa kapangidwe ka ma micro motor.
