Mibvunzo Inowanzo bvunzwa

Sei mabheyaringi ebhora akadzika achishandiswa mumota dzemagetsi dzinomhanya zvikuru?

Dzinotsigira mitoro ye radial uye mitoro ye axial iri pakati nepakati ine kukweshana kushoma, compact geometry, uye high-speed capability, zvichiita kuti dzikwanise ma EV traction motors, spindles, actuators, uye mamwe mashandisirwo emota dze precision.

Chii chinonzi bearing speed factor ndm?

Chinonyanya kukosha che speed factor ndm chakaenzana nekumhanya kwekutenderera muRPM kwakawedzerwa nedhayamita yedenderedzwa re bearing pitch mumamilimita. Mota dzemagetsi dzinomhanya zvikuru dzinogona kushanda pakati pe 1.0 × 10^6 kusvika 1.5 × 10^6 mm/min, zvichida kugadzirwa kwakanyatsonaka.

Ndirini pandinofanira kusarudza mabheyaringi akanyatsonaka emota?

Sarudza kunyatsoita zvinhu, senge ABEC 7 kana ISO P4, kana kudedera, kupisa, ruzha, kana kugadzikana kwekumhanya zvichikosha. Mari yakawedzerwa inogona kusimbiswa kana ikavandudza kushanda zvakanaka, kuvimbika, uye mashandiro ewarandi.

Kumhanya kwakanyanya kunokanganisa sei kugona kwekutakura mutoro wekutakura?

Magadzirirwo emabheya anomhanyisa anowanzo shandisa zvinhu zvidiki zvinotenderera kuderedza simba repakati nepakati uye kukweshana. Izvi zvinogona kuderedza chiyero chemutoro unoshanduka, saka mainjiniya anofanira kuyera kugona kwekumhanya zvichienderana nezvinodiwa nemutoro we radial ne axial.

Sei kukodzera kwemugodhi kuchikosha paRPM yakakwira?

Kana tambo yakakwira, rin'i yemukati inogona kukura kubva pamhedzisiro ye centrifugal. Kana kupindirana kusina kukwana, micro-slip kana fretting zvinogona kuitika; kana yakanyanya kusimba, nzvimbo yemukati inogona kurasika, zvichiwedzera njodzi yekupisa uye kutadza kushanda.
