(7) ngodya ya sawtooth

Magawo a ngodya ya sawtooth ndi ovuta kwambiri komanso akatswiri kwambiri, ndipo kusankha kolondola kwa magawo a macheka ndi chinsinsi chodziwira ubwino wa macheka. Zofunikira kwambiri za ngodya ndi rake angle, mbali yopumula ndi ngodya ya wedge.

Makona ake amakhudza kwambiri mphamvu zomwe zimagwiritsidwa ntchito pocheka tchipisi tamatabwa. Kukula kwa ngodya yocheka, kumapangitsanso kudula bwino kwa macheka, kuphweka kwa macheka, komanso kulephera kukankhira zinthuzo. Nthawi zambiri, zinthu zomwe ziyenera kukonzedwa zili zofewa, ngodya yokulirapo imasankhidwa, apo ayi pang'ono imasankhidwa.

(8) Kusankha pobowo

Kubowola ndi gawo losavuta, lomwe limasankhidwa makamaka malinga ndi zofunikira za zida, koma kuti mukhalebe okhazikika pa tsamba la macheka, ndi bwino kugwiritsa ntchito zida zokhala ndi kabowo kakang'ono ka macheka pamwamba pa 250MM. Pakali pano, m'mimba mwake wa zigawo muyezo anapangidwa muzapakhomonthawi zambiri mabowo 20MM ndi awiri a 120MM ndi pansi, mabowo 25.4MM a 120-230MM, ndi mabowo 30 oposa 250. Zida zina zotumizidwa kunja zimakhalanso ndi mabowo 15.875MM. Kubowola kwamakina kwa macheka amitundu yambiri kumakhala kovuta. , Zambiri zokhala ndi keyway kuonetsetsa bata. Mosasamala kukula kwa kabowo, imatha kusinthidwa ndi lathe kapena makina odulira waya. Lathe imatha kutembenuza gasket kukhala pobowo lalikulu, ndipo makina odulira waya amatha kukulitsa dzenjelo kuti akwaniritse zofunikira za zida.

Mndandanda wa magawo monga mtundu wa aloyi wodula mutu, zinthu za gawo lapansi, m'mimba mwake, chiwerengero cha mano, makulidwe, mawonekedwe a dzino, ngodya, ndi kabowo zimaphatikizidwa pamodzi.carbidetsamba la macheka. Iyenera kusankhidwa moyenerera ndikufananizidwa kuti ipereke kusewera kwathunthu ku zabwino zake.
