Kab ntsig 3-Lub tog raj kheej Hloov Cov Ntaub Ntawv Master Rebuild Set — Driveline Synchronization Kit Rau Cov Khoom Siv hnyav

Thaum lub cav 4-lub tog raj kheej tsim lub zog sib tshooj uas ua rau lub zog xa tawm, 3-lub tog raj kheej tsim (siv ntau hauv Caterpillar's C3.3, C3.6, thiab C3.8 lub cav) tsim kom muaj lub suab nrov 1.5-ceev excitation. Qhov kev vibration no, ua ke nrog kev hloov pauv tam sim ntawd los ntawm cov kab ke sib koom ua ke (ua haujlwm txog li 1,800 bar), cuam tshuam cov ntaub ntawv hloov pauv thiab cov kabmob mus rau kev qaug zog uas maj mam nce rov qab. Thaum backlash ntau tshaj 0.30 mm, lub driveline lash tsim ib lub voj voog tawm tswv yim: ECU txhais cov kev hloov pauv raws li qhov kev thov hloov thiab kho lub sijhawm txhaj tshuaj raws li - tsuas yog kom dhau qhov raug, ua rau kev tsheb ciav hlau siab oscillations. This master rebuild kit is designed to break that loop by providing every measurement and extraction tool needed to restore the transfer case to factory concentricity, without removing the entire driveline from the machine.

Engineered rau Caterpillar's 3-lub tog raj kheej powered compact khoom - nrog rau cov mini-excavators (303.5, 304, 305, 306), compact log loaders (906, 907, 908), thiab skid steer loaders (236, 246, 262-cov khoom no) ib leeg-ceev thiab ob-ceev hloov pauv kis nrog 1.25: 1 rau 1.55: 1 iav piv. Nws tso cai rau kev cob qhia los ntsuas cov iav mesh, rov pib dua cov kabmob preload, thiab nruab cov ntsaws ruaj ruaj tshiab nrog kev txiav txim siab, tag nrho cov ntaub ntawv hloov chaw tseem txuas rau lub tshuab subframe - txuag ntau tshaj 6 teev ntawm lub sijhawm disassembly piv rau cov qauv siv.

Bearing Race Puller Set- Plaub nthuav dav collets uas tuav lub puab haiv neeg ntawm taper roller bearings (Timken LM11949 / LM11910 thiab loj dua LM501349 / 501310). Ib tug swb-rauj nrog lub peev xwm 1.5-tuj rho tawm kev sib tw yam tsis tau qhab nia ntawm lub tsev bores.

Preload Torque Fixture- Ib qho kev cai dial-inch adapter uas ntsuas lub rotating drag torque ntawm cov zis ncej bearing pob. Specification: 6 - 10 in-lb rau cov kabmob tshiab, nrog rau kev daws teeb meem 0.25 in-lb. Lub fixture ncaj qha hloov lub yoke txiv ntoo, tso cai rau shim kho yam tsis muaj rov sib dhos.

Backlash Measurement Set- Qhov taw qhia magnetic-base dial (0.01 mm daws teeb meem) nrog rau kev sojntsuam nkhaus uas hu rau lub iav hniav flank. Cov khoom siv suav nrog peb qhov ntsuas cov hlau lead-hlau rolls (0.15 hli, 0.25 hli, 0.35 hli) txhawm rau ntsuas qhov rov qab sai - lub hom phiaj: 0.12 - 0.22 hli rau cov iav tshiab, qhov siab tshaj plaws hnav txwv 0.30 hli.

Input Ncej tuav Bar- Ib tug 250 mm ntev cov tshuaj tiv thaiv caj npab nrog ob lub dowel pins uas koom nrog lub flange bolt qhov, ua kom ruaj ntseg nruj ntawm cov txiv ntoo input mus rau 280 Nm yam tsis muaj kev sib hloov ncej. Lub bar muaj 3/4 "tsav rau lub torque multiplier.

Foob & Bearing Installer Drifts- Rau kauj ruam mandrels rau nias nyob rau hauv lub dual-lip tso zis ncej foob, lub O-ring rau lub hloov diav rawg npog, thiab koob bearing rau lub nruab nrab iav. Txhua lub drift yog laser-cim nrog rau txoj kab uas hla siv tau.

Kev ntsuas kev pab- Lub ntsuas qhov ntsuas qhov ntsuas qhov ntsuas vaj tsev nyob qhov rooj ovality (limit < 0.035 mm), ib txheej ntawm cov ntsuas ntsuas ntsuas (0.05 - 0.80 mm), thiab 10 × illuminated magnifier rau tshuaj xyuas iav hniav pitting thiab qhab nia.

Backlash rov qab: Nyob rau hauv 50 kis mob los ntawm Cat 308E thiab 906M tshuab, qhov nruab nrab ntsuas backlash ua ntej rebuild yog 0.39 hli. Tom qab siv cov khoom siv los rov pib dua iav mesh rau 0.18 hli, iav suab nrov poob los ntawm 9 dB (A) ntawm tag nrho throttle.

Preload sib xws: Lub torque fixture tsim ib tug preload kis ntawm tsuas yog ± 1.0 nyob rau hauv-lb nyob rau hauv 10 cov kws txawj sib txawv, piv rau ± 4.5 in-lb siv lub "tighten-by-feel" mus kom ze - ua rau lub neej ntev sealing.

Sijhawm efficiency: Lub sij hawm tsim kho nruab nrab (nrog rau kev hloov pauv thiab kev hloov kho) yog 6 teev 20 feeb, nqis los ntawm 13 teev thaum siv cov tshuab rub tawm thiab cov ntsuas shim improvised.

Cov ntaub ntawv hloov chaw tso zis ncej tsav lub twj tso kua mis hydraulic thiab lub qag pem hauv ntej. Thaum cov backlash ntau dhau, cov iav hniav sib tsoo thaum lub sij hawm txhua qhov kev sib tsoo, ua rau lub zog ripple uas rov qab los ntawm kev tsav mus rau lub cav crankshaft. Lub crank txoj hauj lwm sensor pom cov kev hloov pauv ceev no thiab teeb liab ECU, uas tom qab ntawd hloov kho lub sijhawm txhaj tshuaj thiab lub sijhawm txhaj tshuaj tseem ceeb kom them rov qab. Qhov kev them nyiaj no feem ntau overshoots, ua rau tus qauv yos hav zoov hauv kev tsheb ciav hlau siab - feem ntau pom raws li 50-bar oscillation ntawm idle. Los ntawm qhov raug teeb tsa rov qab thiab cov kabmob preload nrog cov khoom siv no, cov kab tsav tsheb dhau los ua pob tshab rau cov txheej txheem tswj, tso cai rau ECU tswj cov kev txhaj tshuaj ruaj khov thiab txo qis kev tsim los ntawm kwv yees li 12% hauv kev sim teb.

Tsis tas li ntawd, cov khoom siv suav nrog qhov ntsuas qhov ntsuas qhov ntsuas tso cai rau cov kws tshaj lij txhawm rau txheeb xyuas tias qhov tso tawm flange lub radial runout nyob rau hauv 0.05 hli - yog qhov tseem ceeb vim tias kev khiav tawm ntau dhau ua rau lub twj tso kua mis hydraulic input ncej rau wobble, ua rau lub siab ripple uas ncaj qha cuam tshuam rau lub kauj thiab siv cov kev tswj hwm.

❓ Q1: Cov khoom siv no puas tuaj yeem siv rau ntawm lub cav C3.6 tshiab nrog qhov "siab dua torque", uas muaj cov qauv sib txawv ntawm flange ntsia liaj qhov rooj?
Yog - lub tuav tuav muaj ob txheej ntawm tus pin qhov (60 mm thiab 70 mm PCD) uas npog ob qho tib si tus qauv thiab high-torque flange qauv. Cov khoom siv kuj suav nrog cov khoom siv tuab tuab ntawm cov txiv ntseej lub qhov (socket) adapter rau 36 hli hex siv rau ntawm qhov sib txawv siab-torque.

❓ Q2: Kuv tau hloov cov zis ncej bearings nrog cov khw muag khoom tom qab (piv txwv li, NTN tsis yog Timken). Puas yog qhov preload torque spec tseem zoo li qub?
Tus cab torque ntau (6-10 in-lb) yog raws li cov kabmob loj thiab kev tshem tawm sab hauv, tsis yog hom. Txawm li cas los xij, tom qab kev muag khoom bearings yuav muaj qhov sib txawv me ntsis tawg-tawm torque. Peb pom zoo kom teem lub preload mus rau qis kawg ntawm qhov ntau (6 in-lb) thiab rov kuaj xyuas tom qab 50 teev ua haujlwm - qhov kev sib tw tso cai rau kev kuaj xyuas sai.

❓ Q3: Txoj kev siv lead-hlau rau kev ntsuas backlash zoo li qub - puas muaj lwm txoj hauv kev?
Cov khoom siv kuj tseem suav nrog qhov kev xaiv tus lej xov tooj nrog lub Bluetooth tso zis (muag nyias) uas nyeem ncaj qha hauv 0.001 hli. Rau feem ntau cov kev cob qhia, txoj kev siv lead ua hlau yog sai dua thiab yuav tsum tsis muaj roj teeb - tsuas yog yob cov hlau ntawm cov hniav, ntsuas nws cov tuab nrog cov micrometer suav nrog, thiab piv rau daim ntawv hnav.

❓ Q4: Yuav ua li cas yog tias cov ntaub ntawv hloov mus rau lub tsev bore hnav dhau qhov txwv ovality (0.035 mm) - Kuv puas tuaj yeem siv cov khoom siv?
Yog hais tias lub ovality tshaj 0.035 hli, cov kabmob yuav tsis pom zoo txawm tias muaj qhov tshiab. Nyob rau hauv tas li ntawd, peb pom zoo kom rov tho txawv thiab txhim kho lub tes tsho kho - ib qho kev pab uas peb muab cais. Cov khoom siv suav nrog lub ntsuas qhov ntsuas los txiav txim qhov mob no ua ntej koj pib rov ua dua.

❓ Q5: Puas yog cov teeb no suav nrog cov shims rau kev kho lub preload, lossis kuv puas yuav tsum tau yuav lawv cais?
Peb suav nrog kev pib ua haujlwm ntawm 12 shims (0.05, 0.10, 0.15, 0.20, 0.30, thiab 0.40 mm, ob leeg). Qhov no suav nrog ntau dua 80% ntawm kev tsim kho dua tshiab. Yog tias koj cov ntaub ntawv tshwj xeeb xav tau cov thickness txawv txawv, peb muab cov khoom siv shim tag nrho raws li SKU cais.

❓ Q6: Kuv tab tom ua haujlwm ntawm Cat 262D skid steer nrog ob-ceev hloov cov ntaub ntawv - puas yog cov cuab yeej hloov kho qhov nkhaus tuaj nrog cov teeb no?
Yog - lub teeb muaj xws li ib khub ntawm cov pins sib dhos nrog lub caij nplooj ntoos hlav-loaded detents uas xauv qhov kev hloov tsheb ciav hlau nyob rau hauv qhov chaw nruab nrab thaum lub sij hawm reassembly. Cov pins tau cim meej "H" thiab "L" rau qhov chaw siab thiab qis qis, ua kom muaj kev sib koom tes zoo yam tsis muaj kev khi.

 

Txhawm rau ua kom koj qhov kev yuav khoom tau yooj yim thiab yooj yim, peb muab ntau yam kev xaiv them nyiaj ruaj ntseg:

Peb nyob ntawm no los ua kom koj cov txheej txheem xaj kev txhawj xeeb-dawb - xaiv txoj kev them nyiaj uas ua haujlwm zoo tshaj rau koj!
