Crank mashandiro: ngationei

Modern injini rine muzvizhinji ine hurongwa pakati izvo pane lubrication hurongwa, mafuta maitiro uye kuvesa gadziriro. Vose kusanduka nenguva, vanosangana nokuchinja uye huchawedzera akakwana. Asi pane dzimwe nhengo kuti kumbochinja munyika yose nguva ivepo. Somuenzaniso, imwe crank mashandiro. Chokwadi ndechokuti kubvira kwayo kuvamba, izvozvo yakaramba kwaro yepakutanga chimiro.

Kushandiswa Its rakanyatsojeka broadly uye hakungoitwi pezviri combustion injini. Rinoshandiswa pamitambo yakadaro ndipo kunodiwa translational kufamba, achangogara zviri kupa kwete chete panguva iyoyo nemafambiro izvi, asiwo kugara akurumidze, iro rine parinoperera Kureba crankshaft ibvi.

Crank mashandiro yakatanga kuiswa pamusoro hwemvura chokugadza ipapo, mushure womukati injini yacho yakagadzirwa, akatamira pamusoro azvino kukura. Pane mhando mbiri mezviruva: mumwe transmits simba kubva crankshaft kusvikira zvizere kuti anoita mberi inofamba, wechipiri anowana simba kubva pisitoni, riri mumwe mugumo unobva tsvimbo.

Funga chinangwa chimwe nechimwe chikamu yoga. The huru Chikamu - munhu crankshaft. Chinogona kuparadzira simba patsvimbo kana, Ukuwo, kuzvigamuchira. It chakagadzirwa mukuru-simba steels, kazhinji yakagadzirwa kukandira simbi. Riri flywheel iyo inoshandiswa kuti achengetere akagamuchira simba. vatyairi zhinji dzishandise munhu lightweight flywheel pamusoro injini wako, kuita crank mashandiro zvikuru zvatinogadzira hazvigoni kunyatsotevedzera zvinoita. Akangoti nokukurumidza kuwedzera.

Zvino pane tsvimbo. Zvinonzi rakagadzirwa hwakasimba sesimbi mamakisi, nokuti kumanikidzwa pairi zvinogona kuvhiringidza. Uyezve, ane chimiro netsvimbo I-mugero, nekuti ayo deformation ine migumisiro kuti kukuvara uye humburumbira.

The crank mashandiro ane guru torque pane muhombe michini, sezvo anoshandisa nheyo inofambiswa mhikuriso, i.e., simba rayo riri Proportional kuti urefu ibvi. Nokudaro mhedziso; zvikuru ibvi, dzakanga dziri torque. Next chinhu - the pisitoni. The pisitoni anogona kutyaira crankshaft sezvo dzomunyika injini, kana kugamuchira kubva simba sapamazuva compressors. Zvinonzi dzaiwanzogadzirwa aruminiyamu, nokuti chinoda dzakapfavirira simbi, kuti tisakuvara rusvingo humburumbira kana kunyorerana. On the mukomberedzo vari circumferential grooves umo pisitoni marin'i vari akaiswa, ivo vanoshumira kusimbisa uye kuwedzera kumanikidza. Panyaya iyi, iyo magasi kuita basa zvikuru.

The crank mashandiro ari injini rinowanikwa kuwana avhareji yacho torque uye nokukurumidza, somunhu zvaizopedza mumwe parameter kunotungamirira nokurasikirwa mune dzimwe. The pamusoro akatsanangura nzira kuwedzera wokutanga, asi muchiitiko chino ari pisitoni vachafanira kuti afambe daro refu, iyo kunokanganisa "sirin'i" kuti kumukira.

Vaz gwenya ungano haisi zvakasiyana kubva apa. Yeuka kuti vose zvikamu crank inofanira lubricated kwazvo sezvo rotates nokukurumidza kwazvo. Kubva pakatanga kugadzirwa pakati kuberekesana zvikamu kumanikidzwa mafuta firimu iri choga zvakati anoderedza muchapfekei.
