Iyo crankshaft ndiyo chikamu chikuru chinotenderera cheinjini. Mushure mekunge tsvimbo yekubatanidza yaiswa, inogona kuita kumusoro uye pasi (kudzokerana) kufamba kwetambo yekubatanidza uye kuishandura kuita cyclic (inotenderera) kufamba.
Icho chikamu chakakosha cheinjini. Chinhu chayo chinogadzirwa nekabhoni structural simbi kana ductile iron. Iine zvikamu zviviri zvakakosha: bhuku guru, rodhi rekubatanidza tsvimbo (nezvimwe). Iyo huru jenari yakaiswa pane cylinder block, iyo yekubatanidza tsvimbo jenari yakabatana negomba hombe rekupedzisira retambo yekubatanidza, uye diki magumo eiyo tsvimbo yekubatanidza yakabatana necylinder piston, inova yakajairwa crank-slider mechanism. .
Crankshaft processing tekinoroji
Kunyangwe kune akawanda marudzi e crankshafts uye mamwe maitiro ezvimiro akasiyana, tekinoroji yekugadzira yakada kufanana.
Main process sumo
(1) Kuburikidza kwekunze kwe crankshaft main journal uye yekubatanidza rod journal Panguva yekugadziriswa kwe crankshaft zvikamu, nekuda kwesimba rechimiro che disc milling cutter pachayo, iyo yekucheka kumucheto uye workpiece inogara ichibatana nepakati neiyo workpiece, uye pane kukanganisa. Naizvozvo, iyo clearance link inodzorwa mune yese yekucheka sisitimu yemuchina wemuchina, iyo inoderedza kuzununguka kunokonzerwa nekufamba kubvumidzwa panguva yekugadzira machining, nekudaro inovandudza machining kurongeka uye hupenyu hwesevhisi yechishandiso.
(2) Kukuya crankshaft main jenari uye rekubatanidza jenari yetsvimbo Nzira yekuronda yekuronda inotora pakati pejenari guru sepakati pekutenderera, uye inopedzisa kukuya kwejenarari yetsvimbo ye crankshaft mune imwe clamping (inogonawo kushandiswa kuhombe). journal grinding), kugaya Nzira yekucheka majenari etsvimbo yekubatanidza kudzora kudya kwevhiri rekukuya uye maviri-axis linkage yekufamba kwe rotary. yeworkpiece kuburikidza neCNC kupedzisa chikafu che crankshaft. Iyo yekutevera nzira yekugaya inotora imwe clamping uye inopedzisa kukuya kwe crankshaft main jenari uye yekubatanidza tsvimbo yejenari inoshandura CNC yekukuya muchina, inogona kunyatso kudzikisa mutengo wemidziyo, kuderedza mutengo wekugadzirisa, uye kugadzirisa iko kurongeka nekubudirira kwekugadzira.
(3) Iyo crankshaft main jenari uye yekubatanidza tsvimbo yejenari fillet rolling muchina chishandiso chinoshandiswa kuvandudza kuneta kwesimba re crankshaft. Maererano nehuwandu, hupenyu hwe ductile iron crankshaft mushure mokunge fillet rolling inogona kuwedzerwa ne 120% kusvika 230%; Hupenyu hwesimbi yakaumbwa crankshafts mushure mekukunguruka kwefillet inogona kuwedzerwa ne70% kusvika 130%. Simba rekutenderera rekutenderera rinobva mukutenderera kwe crankshaft, iyo inotyaira ma rollers mumusoro unotenderedza kuti atenderere, uye kudzvanywa kwema rollers kunoitwa neoiri cylinder.
