Excavator slewing bearings ho hlahloba letsatsi le letsatsi

Slewing bearing lubrication

Li-bearings tsa Slewing li lokela ho tlotsoa kamehla ka No. 2 khatello e feteletseng ea lithium grease. Thepa e potolohang butle kapa lisebelisoa tsa ho tsubella (mohlala, li-backhoe, li-excavator, crane) li lokela ho nchafatsoa lihora tse ling le tse ling tse 100 tsa ts'ebetso. Bakeng sa lisebelisoa tse tsamaeang ka potlako kapa tse ntseng li potoloha, joalo ka li-trenchers le li-driller, ho ka hlokahala hore ho tlosoe hangata, letsatsi le letsatsi kapa esita le lihora tse ling le tse ling tse robeli. Ha o eketsa grease, ho beleha ho lokela ho pota-pota ho hasanya mafura hohle. E tšele ho fihlela u bona mafura a khale a phunyeletsa ka har'a tiiso; Sena se bitsoa tlhoekiso ea letlalo. Mafura a tlositsoeng a na le litšila ho tsoa lesale la ho bolaea. Haeba u fumana li-grit kapa li-chips tsa tšepe, ho ka 'na ha e-ba le bothata ka har'a selikalikoe sa ho bolaea' me u lokela ho emisa ho hlahloba. Mafura a omella ka nako e telele, e leng se ka etsang condensation ka hare ho bering. U ka qoba sena ka ho eketsa mafura bonyane likhoeli tse ling le tse ling tse tšeletseng, le haeba thepa e sa sebetse.

Lubrication ea lisebelisoa

Li-bearings tse ngata tse kholo li na le meno a hlokang ho tlotsoa, ​​'me litlhoko tsena li fapane le tsa bere ka boeona. Hobane ts'ebetso ea ho kopanya ha meno e atisa ho ntša mafura, likere li lokela ho tlotsoa lihora tse ling le tse ling tse robeli bakeng sa lisebelisoa tse bilikang butle kapa ka nakoana, 'me hangata ho lisebelisoa tse bilikang kapele kapa tse sa khaotseng. Palo e nyane ea mafura e lokela ho eketsoa sebakeng sa meshing lipakeng tsa gear le pinion.

Ho eletsoa ho etsa tlhahlobo ea pono ea kamehla ea litiiso holim'a li-bearings tse bolaeang ho netefatsa hore li tiile. Batho ba bangata ba iphapanyetsa bohlokoa ba liqibi, empa ba thusa haholo ho thibela tšilafalo ea litsela tse tšehetsang.

Bolt

Ho hlahloba liboutu tsa torque e lokela ho ba karolo ea tloaelo efe kapa efe ea ho lokisa. Khafetsa ea litlhahlobo tsena e itšetlehile ka boima ba tšebeletso. Ho thothomela le ho tsukutleha ho na le ho lokolla liboutu, empa ho lekola torque khafetsa le ho tiisa ho tla thusa ho boloka maemo a nepahetseng a ho jara pele. Liboutu tse ntseng li kenngoa li lokela ho tiisoa ho isa boemong bo nepahetseng 'me li hlahlojoe khafetsa ho netefatsa hore li jara esale pele. Liboutu tse sa kenngoeng hantle esale pele li ka 'na tsa hlōleha, tsa baka tšenyo ea thepa.
