Relative lubrication difficulties and s★εolutions for bearing lubrication
Main lubrication problems ♥♣€for bearing lubrication:
※Strict long-life lubrica♣&Ω♥tion requirements, be§∏å grease evaporates too quickly&β♣ , becomes dry after a pe₹•↓<riod of time, insufficient lubricati™©αon, causing sintering;
※Bearings are prone to fatigue and '¥fall off, the oil film formed by bea☆≥± ring grease is thin, easy to be punctu £red, and difficult to repair≠"δ;
※Bearing rust, bearing greaδ se has poor rust resistance and corros↑↑§∞ion resistance;
※Bearing abnormal noise, grease is co∏₹ntaminated in the production process o>€πf bearing grease, and there &φ♥are impurities and partic×♥'les, causing bearing pitti±≈≥ng and abnormal noise;
※Strict environmental protec"tion requirements, many gre≠>γ→ases have not passed relevant environme±"ntal protection cert ♠≈ification; ……
Solution:
※ Since lubricating grease will dry&α∏ out after a period of time, you γ¶✔need to choose lubricating grease m<&ade of high-grade precisi>✘≤on base oil and precise process;
※ For bearing fatigue peeling,≤& the selected base oil has high viscos★₩ity, and the formed oil film π×is thick and not easy to penetrateα;
※ Add rust inhibitors and ≤&÷™antioxidants to the grease<&¶ to provide rust, rust and aging r← ←¶esistance of the grease;
※ For abnormal noise α↓→of bearings, strictly control th↔✔♣e production process, purify theε∞ production environment, ∑αand ensure that the grease is ¶¶↓✘pollution-free;
※ In response to the requirements ←₩∏Ωof the current market, all auto↑δ♥↓motive products must mee↔λ ₹t environmental protection require →÷≥ments……
Simulation bench test:
Basic introduction:
※The test bench can perform du¥"δ∏rability tests on bearings of models "÷₹ε608, 6201, 6204, and 6303.
※Four sets of bearings can be tested si≈₹☆≠multaneously in each experi©★ε★ment. The maximum speed™ "£ of the test machine ☆ γis 30,000 rpm. It can simula✘↑<♦te both normal temperature tests a&♣♥nd high temperature tests (maximum§®>☆ 180°C).
※The bearings can be loaded ∑§∏πradially (maximum 5,000N) and axia&©$lly (maximum 2,000N).
