Katundu wa Excavator Pansi Roller

Mndi shaft :Mzitsulo ndi 50Mn zapamwamba za carbon structural steel, zomwe zili ndi C kuyambira 0.48 mpaka 0.56%, Si zomwe zili pa 0.17 mpaka 0.37%, Mn zoyambira 0.7 mpaka 1.0%, S zomwe zili pansi pa 0.035%, P zomwe zili kuchokera pansi pa 0.035%, ndi Cr zomwe zili pansi pa 0.25 mpaka 0.30%, zomwe zili ndi Ni kuyambira zosakwana 0.30%, ndi Cu zomwe zimakhala zosachepera 0.25%. imatha kukonza ductility ndi pulasitiki ya zinthuzo, kuonetsetsa kulimba kokwanira komanso kukana kuvala.Pambuyo pa chithandizo cha kutentha, chitsulo cha 50Mn chimakhala ndi mphamvu zambiri komanso kuuma, kulowera kwabwino, kusanjikiza kozama, ndi maonekedwe abwino a pearlite, komanso makina abwino.

Miyezo yopangira shaft yayikulu imafuna kuya kwa 2 mpaka 7 mm ya wosanjikiza wowumitsa ndi kuuma kotentha kwa 50 mpaka 62 HRC.

Thupi :Kuti muwonjezere kukana kwa avaletwodzigudubuza's thupi, zakuthupi ndi 40Mn2 aloyi structural chitsulo, ndi C okhutira kuyambira 0.37 kuti 0.44%, Si zili kuyambira 0.17 kuti 0.37%, Mn zili kuyambira 1.4 mpaka 1.8%, P okhutira kuyambira zosakwana 0.030%, ndi S okhutira kuyambira kuchokera ku 0.030%.

The wodzigudubuza pansiThupi limapangidwa ndi njira yopangira. Pambuyo popanga, thupi la gudumu lolimba limasinthidwa kuti likwaniritse kuuma kwa 26-32HRC kuti likhalebe ndi mphamvu zambiri, pulasitiki, kulimba, ndi machitidwe onse amakina mkati mwa gudumu.Magudumu thupi pamwamba amapatsidwa mankhwala quenching kuonjezera kuuma ndi kuvala kukana kwa gudumu thandizo njanji pamwamba.The quenching kuuma ndi 50-58HRC, ndi kuya kwa 6-12mm.Izi zimabweretsa kufanana kwakukulu pakati pa kulimba kwa njanji ndi kulimba kwa maulalo a unyolo (48-58HRC).

Chisindikizo:Kukula ndi pamwamba roughness waO-ringkuyenera kukhala kogwirizana ndi kapangidwe kake.Pamalo okwererako akuyenera kuzunguliridwa, ndipo payenera kukhala kutsukidwa kwa ma burrs aliwonse ndi m'mbali zakuthwa.

Labala yosindikizidwa yoyandama ndi O-mpheteziyenera kusankhidwa kuchokera ku mphira wapamwamba wa butyl.Kuzungulira kwamkati, kukula kwa ulusi, kusungunuka, kuuma (M'mphepete mwa nyanja), ndi mapeto a pamwamba onse ayenera kugwirizana ndi miyezo.Pamaso pa msonkhano, zonse zomwe zili pamwambazi ziyenera kuyang'aniridwa ndikuyenerera malinga ndi zomwe zili pamwambazi musanayike.

Kusiyana :Chilolezo pakati pa axle main axis ndi hub yonyamula pawodzigudubuzathupi liyenera kukhala 0.2-0.4 mm. Pozungulira, sikuyenera kukhala kutsekerezavutondi ntchito yabwino yosindikiza, palibe kutayikira kwa mafuta.

Kupaka mafuta :Mafuta ofunikira m'thupitrack rollr ayenera kubayidwa pogwiritsa ntchito pampu yamafuta.Pakafunika, kukhuthala kwamafuta opaka mafuta kumatha kuonjezedwa moyenerera.Musanabaya mafuta onyamula, mafuta opangira ntchito ayenera kukhetsedwa.Kenaka, mafuta atsopano ayenera kuwonjezeredwa ku bowo la pulagi ya mafuta mpaka mafuta atuluka.Pobaya mafuta opaka mafuta, phula la hub cap liyenera kuchotsedwa, ndipo mapeto a mafuta a chipangizo chopangira mafuta ayenera kukanikizidwa paphewa panjira yamafuta.
