Ko te whakawātea axial o te crankshaft ka kiia hoki ko te whakawātea mutunga o te crankshaft. I roto i te mahi miihini, mena he iti rawa te aputa, ka mau nga waahanga na te toronga werawera; Mena he nui rawa te aputa, ka puta te nekehanga axial o te crankshaft, ka tere te kakahu o te cylinder, ka pa ki te mahi noa o te wahanga takirere me te mamau. Ina whakahouhia te miihini, me tirotirohia te rahi o tenei aputa me te whakatika kia pai.

Kei roto i te inenga o te whakawātea crankshaft te inenga whakawātea axial me te inenga whakawātea radial bearing matua.

(1) Inenga o te axial whakawātea o crankshaft. Ko te matotoru o te pereti e mau ana i te pito o muri o te crankshaft e whakatau ana i te waatea axial o te crankshaft. I te ine, tuu he tohu waea ki te pito o mua o te crankshaft miihini, patotohia te crankshaft kia neke whakamuri ki te tuunga tepe, katahi ka whakahāngai i te tohu waea ki te kore; katahi ka neke whakamua te crankshaft ki te waahi tepe, katahi ko te tohu waea Ko te tohu o ko te axial clearance o te crankshaft. Ka taea hoki te ine ki te mehua ite; whakamahia kia rua nga wiriwiri hei whakauru i waenganui i tetahi uhi kawe matua me te ringaringa crankshaft e rite ana, a i muri i te werohanga i te crankshaft ki mua, whakamuri ranei ki te tuunga tepe, whakaurua te ine kare ki roto i te pikaunga tuawhitu. , ko tenei aputa ko te axial axial o te crankshaft. E ai ki nga ture o te wheketere taketake, ko te paerewa mo te whakawātea axial o te crankshaft o tenei motuka he 0.105-0.308mm, ko te rohe kakahu he 0.38mm.

(2) Te ine inenga inenga o te kawe matua. Ko te whakawāteatanga i waenga i te hautaka matua o te crankshaft me te kawe matua ko te whakawātea radial. I te wa e ine ana, whakaurua te ine waea kirihou (gap plastic gauge) ki waenga i te hautaka matua me te pikaunga matua, kia tupato kei huri i te poroporo kia kore ai e huri te mokowhiti i te wa hurihuri me te ngau i te ine aputa. Me whai whakaaro ki te awe o te kounga o te crankshaft i runga i te waatea.
