Musoro wecylinder chinhu chakakosha chechimiro cheinjini. Iyo huru yemafuta passage gomba chikamu chakakosha chemusoro wecylinder. Kana gomba guru remafuta riine maburrs, mabhura anovhara hydraulic tappet mafuta paanopinda mugomba reHVA, zvichiita kuti itadze. , Izvo zvinoita kuti vharuvhu yemusoro wecylinder isakwanise kuvhara, zvichiita kuti cylinder block ishaye macylinders. Naizvozvo, zvinodikanwa kuve nechokwadi kuti hapana maburrs anoramba ari mugomba guru remafuta.

Zvikonzero zvemaburrs pamakomba emafuta ehumburumbira:

Kudhirowa kwegomba rehumburumbira remusoro wehumburumbira ndiko kutsvedza kweshear kunogadzirwa nechibooreso chechishandiso chinodzvanya chishandiso. Nekuda kwechimiro uye kurongeka kwegwaro remafuta pacharo, mipendero, makona, uye makona pamharadzano yemafuta maviri kana anopfuura anoumbwa. Mupendero uchaonekwa hombe epurasitiki deformation, chibooreso uye workpiece ichava nekuparadzanisa nzira pamharadzano, iyo iri nyore kwazvo kugadzira burrs.

Mhedzisiro mikuru ye cylinder head oil hole burrs ndeiyi:

1. Kukanganisa kurongeka kwedimensional yeworkpiece;
2. Kukanganisa kana kukanganisa kuyerwa kwechiyero che workpiece;
3. Mabhururu anowira pasi panguva yekugadzirisa kana kutakura, izvo zvinokanganisa kuchena kwezvikamu;
4. Munguva yekugadzira, burr inowira uye kune ngozi yekuchengeteka yezvikwepa uye kucheka;
5.Pakati pekugadzirisa kunotevera, burr inowira uye inokonzera kurasikirwa kwechikamu (negative chikamu), chinoita kuti chikamu chibviswe;
6. Mboro inodonha, uye bhera rinowira pakati pechivharo checamshaft nekavha yecamshaft, zvichikonzera kusakara kwecamshaft uye chivharo checamshaft kana kunyange kukiya camshaft;
7. Iyo burr inowira muVVT mechanism uye inoita kuti michina iite jam uye inokundikana;
8. Kukanganisa iyo lubrication maitiro, nekudaro kukanganisa injini kuita.
