Njira 5 zosamalira ma bulldozers

1. Konzani mayendedwe a bulldozer

Kuonetsetsa moyo wautali wa njanji za bulldozer, ndikofunikira kusunga kukhazikika koyenera. Kumangitsa kwambiri kungayambitse kupsinjika kwambiri pamapini a njanji ndi tchire, zomwe zimapangitsa kuti avale msanga. Kuphatikiza apo, kukangana kwa kasupe waudzu kumatha kutha tsinde ndi tchire, zomwe nthawi zambiri zimapangitsa kuti pakhale mawonekedwe ovala mozungulira pamtundu wa idler. Izi sizimangotambasula nsapato za njanji koma zimachepetsanso mphamvu zamakina, zomwe zimapangitsa kuti mphamvu iwonongeke kuchokera ku injini kupita ku sprocket ndi njanji.

Kuthamanga kwa mayendedwe otsika kumatha kuyambitsa kuthamangitsidwa kwa osagwira ntchito ndi odzigudubuza, zomwe zimapangitsa kusalinganika bwino. Izi zimapangitsa kuti njanjiyo isinthe ndikusintha mosakhazikika, zomwe zimapangitsa kuti ma roller oyenda ndi osagwira ntchito azivala molakwika.

Onjezani mafuta pamphuno ya jakisoni wamafuta kuti mumangitse njirayo, kapena tulutsani mafuta pamphuno yotulutsa mafuta kuti mumasule. Pamene nsonga ya nsapato ya njanji yatambasulidwa kumlingo wakutiwakuti, kusonyeza kuti nsapato za njanji ziyenera kuchotsedwa, ndi nthawi yokonza. Yang'anani kusavala kwachilendo pamalo okwerera, gawo la mano, ndi tchire. Njira zosamalira zingaphatikizepo kutembenuza pini ndi kugwedeza, kuchotsa mapini ndi tchire zomwe zatha kwambiri, kapena kusintha nsapato zonse za track.

2. Malo oyenerera osasamala

Kuyanjanitsa koyenera kwa munthu wosagwira ntchito ndikofunika kwambiri kuti moyo wamkati ukhale wautali. Chilolezo chapakati pa mbale yolondolera ya idler roller ndi chimango cha njanji chiyenera kusinthidwa kuti chikhale chovomerezeka cha 0.5 - 1.0mm, kuti zitsimikizire kuti zikuyenda bwino komanso kukulitsa moyo waulendo. Shims amagwiritsidwa ntchito kusintha kusiyana pakati pa mbale yolondolera ndi kunyamula. Ngati kusiyana kuli kwakukulu, ma shims amachotsedwa, m'malo mwake, ma shims amawonjezeredwa. Chilolezo chovomerezeka kwambiri ndi 3.00mm.

Ulalo wa njanji, kapena unyolo wa njanji, ndi ma bushings ndi gawo lofunikira kwambiri pamayendedwe apansi a bulldozer. Pakapita nthawi, zigawozi zimatha kuchepa, zomwe zimapangitsa kuti phula (mtunda wapakati pa maulalo) utalike. Izi zitha kupangitsa kuti pakhale kusayenda bwino pakati pa gudumu loyendetsa ndi bushing, zomwe zimapangitsa kuwonongeka ndi kuvala kwachilendo.

Kuwonongeka kumeneku kumatha kuyambitsa zovuta monga kujoka, kuwomba, ndi kugunda, zomwe zingachepetse kwambiri moyo waulendo. Ngati mamvekedwe sangathe kubwezeretsedwa posintha kugwedezeka, kutembenuza pini ndi bushing ndikofunikira kuti mukwaniritse mayendedwe oyenera.

Pali njira ziwiri zodziwira nthawi yotembenuza pini ndi bushing. Njira imodzi ndiyo kuyang'ana kutalika kwa njanji ya 3mm, ndipo ina ndiyoyang'ana ngati kutalika kwa bushing ndi 3mm.

Komabe, ndikofunika kuzindikira kuti ndondomeko yeniyeni ndi miyeso imatha kusiyana malinga ndi chitsanzo cha bulldozer ndi malangizo a wopanga. Nthawi zonse tchulani bukhu la kagwiritsidwe ntchito ndi kasungidwe ka zida zenizeni kuti mudziwe zambiri zolondola.

3. Nthawi Yake Limbitsani Bolts ndi Mtedza

Pamene ma bolts a kayendedwe ka kayendedwe kamakhala kotayirira, amatha kusweka kapena kutayika, zomwe zimapangitsa kuti pakhale zovuta zingapo. Kusamalira tsiku ndi tsiku kuyenera kuphatikizirapo kuyang'ana mabawuti awa: mabawuti okwera a track roller ndi carrier roller, mabawuti okwera a magawo (ma sprocket), mabawuti okwera a nsapato za track, ndi mabawuti okwera a track roller guard plate.

4. Kupaka mafuta pafupipafupi

Kuthira koyenera kwa njira yoyendera ndikofunikira. Ma tracker ma bearings ambiri 'awotchedwa' ndipo amakhala opanda kanthu chifukwa cha kutuluka kwa mafuta komwe sikudziwika munthawi yake. Nthawi zambiri amakhulupirira kuti mafuta amatha kutuluka m'malo asanu otsatirawa: kuchokera ku chipika chotchinga ndi shaft chifukwa cha O-ring yowonongeka kapena yosauka; kuchokera kunja kwa mphete ya chipika ndi chodzigudubuza chifukwa chosalumikizana bwino ndi mphete yosindikizira yoyandama kapena zolakwika za O-ring; kuchokera ku liner ndi roller chifukwa cha O-ring yoyipa pakati pa track roller ndi liner; kuchokera pa pulagi yodzaza mafuta chifukwa cha kumasulidwa kwa pulagi yodzaza mafuta padoko kapena kuwonongeka kwa pulagi ya conical screw kutseka dzenje; ndi kuchokera pachivundikiro ndi chogudubuza chifukwa cha mphete yoyipa ya O. Choncho, fufuzani nthawi zonse za zigawozi, ndipo mafuta ayenera kuwonjezeredwa kapena kusinthidwa malinga ndi kayendedwe ka mafuta a gawo lililonse.

5. Kuyendera kwa Crack

Kukonza ma bulldozer kuyenera kuphatikizira kuyang'ana pa nthawi yake ming'alu yamayendedwe oyenda, ndikukonza zowotcherera mwachangu ndi kulimbikitsa ngati pakufunika.
