Phapang pakeng tsa maqhubu a phahameng le maqhubu a mahareng a quenching a lisebelisoa tse phahameng tsa ho tima

(1) High-frequency quenching e na le lera le sa tebang le thata (1.5 ~ 2mm), boima bo phahameng, workpiece ha e bonolo ho oxidize, e na le deformation e nyenyane, boleng bo botle ba ho tima le ho sebetsa hantle ha tlhahiso, ‘me e loketse likarolo tse sebetsang tlas’a likhohlano. maemo, joalo ka ka kakaretso likere tse nyane, Shafts (lisebelisoa tse sebelisoang ke 45 # tšepe, 40Cr);

2 tšepe, 3Cr, 5Mn45V le tšepe ea ductile) .

(3) Ho futhumatsa maqhubu a phahameng a ho futhumatsa 200～1000kHz 0.5～2.5 Li-gear tse nyane le tse mahareng tsa modulus le likarolo tsa shaft tsa boholo bo mahareng le bo nyane.

(4) Ho futhumatsa maqhubu a mahareng a 2500～8000Hz 2～10 Li-shafts tse kholoanyane le likere tse kholo le tse mahareng tsa modulus.

Ho ea ka maqhubu a hona joale, ho tima mocheso oa ho futhumatsa ka induction ho ka aroloa ka: high frequency quenching 100-1000kHz. Maqhubu a mahareng a tima 1-10kHz. Matla a ho tima 50Hz.

1. Ho thatafala ha lera la bokaholimo ke 2-3HRC e phahameng ho feta ea quenching e tloaelehileng, ‘me e na le brittleness e tlase, matla a mokhathala, le ho ba le tšusumetso e matla. Ka kakaretso, workpiece e ka eketseha ka 20-30%.

2. The deformation e nyenyane, ‘me botebo ba lera la ho tima bo bonolo ho laola.

3. Litšepe tse theko e tlaase tse thata li ka sebelisoa, ts’ebetso e bonolo ho elelloa mochine le ho iketsetsa, tlhahiso e phahameng, e phahameng ea maqhubu a hona joale, e fokolang sekhahla se thata.

(5) Lisebelisoa tsa ho tima maqhubu a phahameng hangata ke 1-2mm, ho tima maqhubu a mahareng hangata ke 3-5mm, ‘me ho tima maqhubu a matla ho ka fihla> = 10-15mm.

(6) Mocheso o phahameng oa maqhubu a ho futhumatsa: maqhubu a hona joale ke 100-500 kHz (kHz), ‘me botebo bo sebetsang ba ho thatafatsa ke 0.5-2 mm (mm). E sebelisoa haholo bakeng sa likarolo tse nyane le tse mahareng tse hlokang lera le thata le thata, joalo ka likere tse nyane tsa Modular, li-shafts tse nyane le tse mahareng, jj.

(7) Ho futhumatsa ha maqhubu a mahareng: maqhubu a hona joale ke 500 ho 10000 Hz (Hz), ‘me botebo bo sebetsang ba ho thatafatsa ke 2 ho 10 mm (mm). E sebelisoa haholo-holo bakeng sa likarolo tse hlokang lera le thata le tebileng, joalo ka likere tse nang le modulus e mahareng, likere tse kholo tsa module, li-shaft tse nang le li-diameter tse kholo, jj.
