Menene crankshaft shock absorber?

A cikin motocin zamani, galibi ana sanya motoci waɗanda zasu iya samun adadi mai yawa na juyin juya hali. Masana'antu ba sa ɗaukar irin wannan dabarar ta ƙera motoci na al'ada kamar na motocin wasanni. A sakamakon haka, ana haifar da girgiza mai ƙarfi a yankin crankshaft. Ana haifar da su ta babban nauyi a kan crankshaft. Wannan na iya haifar da lalacewar wanda bai kammala ba.

Sau da yawa, faɗakarwar injiniya na iya haɗuwa da matsalar aikin wanki mai ƙwanƙwasa ƙwanƙwasa. Wannan ƙaramin ɓangaren motar yana taka muhimmiyar rawa a ƙarfin injin da rayuwar injiniya.

Vibrations a cikin motar suna haifar da sakawa a kan bearings, belts har ma da fashewar crankshaft a wani saurin. Wannan shine dalilin da yasa danshin wanki ya zo wurin taimako a nan. Yana kiyaye injin daga cutarwa daga torsional vibration da kare crankshaft daga lalacewa.

Yaya mahimmancin wanki mai danshi?

Vibration wani ɓangare ne na aikin injiniya. Vibarancin rawar jiki a cikin injin zai rage rayuwar injiniya kuma zai haifar da saurin lalacewa. Wajibi ne a rage waɗannan girgizar.

A mafi yawan ababen hawa ana iya yin hakan tare da dam ɗin ƙyallen wuta. Amma kyakkyawan ragin rawar jiki harma da aikin injiniya shima ana samunsa tare da mai wankin danshi. Babban rawar rawar crankshaft shine rage rawar jiki da rage karar injiniya.

Damper na'urar wanki

Na'urar wanke damper wani sinadari ne na bel ɗin motar, ko maimakon haka, tuƙin famfo, madadin da kwampreso na kwandishan. Yana a gaban crankshaft kuma yana datse ƙananan girgizar da aka samar, wanda galibi ana samun su a cikin injin diesel. Matsayinsa shine rage waɗannan girgizar girgizar ƙasa.

An yi shi da ƙwanƙwasa ƙarfe na waje wanda ke ɗauke da madauri, ainihin roba da ɓangaren ƙarfe na ciki. Roba ce tsakanin ɓangarorin biyu na wanki wanda yake aiki azaman ɗagawa. Saboda sassauƙan sa, yana buƙatar sauyawa akai-akai, kamar yadda lokaci yayi kayan kawai suka karye ko suka zama masu ƙarfi.

Lalacewa ga tayarwar yana haifar da amo mai ƙarfi, zamewa da rawar jiki, lalacewar maɓallin mai maye gurbin sabili da haka ga mai sauya kansa.

Mai wanki na damper iri biyu ne - rufaffiyar kuma nau'in budewa. Buɗaɗɗen damper wanki ya fi yawa a cikin injunan mai. Rufaffen gyare-gyaren wanki ana amfani dashi a injunan diesel.

Yawancin matsaloli masu wanki

Wasu lokuta ƙarfe da sassan roba na wankin danshi zasu saki daga juna. Bayan lokaci, ɓangaren roba na mai wankin zai taurare kuma ya tsage. Wannan ya faru ne saboda tsufa na kayan damping da ƙara ƙarfin inji.

Duk wata nakasa ta injina, murdiya da kananan fashewa suna nufin lokaci yayi da za'a maye gurbinsa. In ba haka ba kayan roba zasu zube kuma mashin din zai daina aiki.

Hakanan taya a kan wanki mai lalacewa zai iya lalacewa idan injin yana yawan aiki. A irin wannan yanayi, manyan fasa sun bayyana. Wadannan lahani suna haifar da kara mai ƙarfi fiye da yadda aka saba idan injin aiki, sabili da haka mawuyacin motsi.

Saboda gaskiyar cewa gefen baya na wankin danshi yana kusa da injin, yana fuskantar babban matsi na zafin jiki. Wannan lamarin yana sa ya zama na roba.

Kowane kilomita 60. duba mai wanki don lalacewa kamar lalata ko fasa yana da shawarar. A matsakaita, bayan kilomita 000. dole ne a shirya sauyawa daga ɓangaren.

Idan muka yi biris da gyaran wanki kuma ba ma bincika lalacewa a kai a kai, zai tsufa da sauri fiye da yadda ya saba kuma zai haifar da lalacewar injin da gyara mai tsada.

Wani dalilin lalacewar wanda bai yi daidai ba ga wankin danshi yana iya zama saitin karfin injin injin da ba daidai ba.

Nasihun Kula da Wanki

Idan kun ga waɗannan alamun alamun akan bincika gani, lokaci yayi da za'a maye gurbin shi da sabo:
