Main lubrication problems of ♣δbearing lubrication: ®
※Strict long-life lubri☆λcation requirements, bearing greaα®se evaporates too quic↓γkly, becomes dry after a period ☆→∞of time, and insufficient lubricatiλ∞≈§on causes sintering;
※Bearings are prone t"£o fatigue and fall oβγ•δff, the oil film formed by bearing grea♠>©se is thin, easy to be p©∏÷unctured, and difficult to repair;
※Bearing rust, bearing §÷grease has poor rust resistance and co£∑rrosion resistance;
※Bearing abnormal noise, grease ↔is contaminated in the produε"ction process of bearing grease, an★δd there are impurities &¥γand particles, causing bearing pitt®₩∑ing to produce abnormal× noise;
※Strict environmental protection requ×÷irements, many greases have$¥÷ not passed relevant environmenta↕§↕l certification; ……
Solution:
※ As the lubricating grease ₽✔≈÷will dry out after a period of ≈λ÷time, it is necessar★<y to select lubricating §✔grease made of high-grade precision ba∞∞§se oil and precise process;
※ For bearing fatigue pee↔£"ling, the selected base oil £εβhas high viscosity, the fo₩₽rmed oil film is thick and nλ♣∑ot easy to penetrate;
※ Add rust inhibitors and∑↓ antioxidants to the gr&π©ease to provide rust, rust a£< nd aging resistance of the grease;
※ For abnormal bearing noise, strictl±¥y control the produc αtion process, purify thβ×₹∑e production environment, and e♦∞&♥nsure that the greas≤±e is pollution-free;
※ In response to the requσ♣δirements of the current mar≈↓ket, all automotive products ©↑must meet environmental protection requ♠♣πirements…
Simulation bench test:
Basic introduction:
※ The test bench can perfo÷ rm durability tests on bearings of mod©☆☆×els 608, 6201, 6204, and 63£γ±£03.
※ Four sets of bearings can be tested ©'ε✘simultaneously in each experiment. The←' maximum speed of the tes™ ∏÷t machine is 30,000 rpm. It ca≠★<n simulate both normal temperat₹∏↓ure tests and high temper& ature (up to 180°C) tests.
※The bearing can be loaded r₽♥ε adially (up to 5000N) and axiall∞¶¥y (up to 2000N).
