Txoj Cai Ua Haujlwm ntawm Zinc-Aluminium Alloy Bushings

High Hardness thiab Hnav-Resistant Matrix: Zinc- aluminium alloy muaj li ntawm 27% txhuas. Tom qab solidification, ib tug loj tus naj npawb ntawm txhuas-zinc intermetallic compound reinforcement theem yog tsim, ho txhim kho hardness thiab tensile zog (txog 400-430 MPa), muab ib tug ruaj khov microscopic kev them nyiaj yug qauv thaum sib txhuam, thiab txo hnav.

Tus kheej -Lubricating Mechanism:
Nyob rau hauv graphite -embedded bushings, siab- purity graphite yog embedded rau hauv qhov pores ntawm matrix (nrog 20% ​​-30% ntawm qhov chaw sib txhuam). Thaum lub sij hawm kev sib txhuam, graphite hloov mus rau mating ncej nto nyob rau hauv thermal thiab mechanical kev txiav txim, tsim ib tug nruam lubricating zaj duab xis, txo cov kev sib txhuam coefficient mus rau 0.06-0.12, ua tiav cov roj- dawb lubrication.

Hauv cov roj porous-muaj cov qauv polymer, roj- cov ntaub ntawv polymer impregnated yog embedded rau hauv lub bushing, tsis tu ncua tso roj nplua nyeem los ntawm ib tug "micro-roj mov" system, txo cov hlau ncaj qha - rau-hlau sib cuag.

Structurely Assisted Lubrication: Qee cov qauv tsim muaj cov roj qhov thiab silicone sealing tshuab, tso cai rau cov roj sab nraud ntxiv lubrication, thiab siv cov elasticity ntawm silicone kom kaw qhov, tiv thaiv cov roj to thiab ncua kev txij nkawm.

Lub teeb yuag thiab tus nqi zoo: Qhov ntom ntawm zinc- aluminium alloy yog li 5.0 g / cm³, 40% -45% sib dua li tooj liab alloys, thiab tus nqi raw khoom tsuas yog 30% -40% ntawm tooj liab- cov ntaub ntawv raws li, ua rau nws tsim nyog rau daim ntawv thov rhiab rau qhov hnyav thiab tus nqi.
