Main lubrication problems of bearing lubrication:
※Strict long-life lubrication requirements, bearing grease evaporates too quickly, becomes dry after a period of time, and insufficient lubrication causes sintering;
※Bearings are prone to fatigue and fall off, the oil film formed by bearing grease is thin, easy to be punctured, and difficult to repair;
※Bearing rust, bearing grease has poor rust resistance and corrosion resistance;
※Bearing abnormal noise, grease is contaminated in the production process of bearing grease, and there are impurities and particles, causing bearing pitting to produce abnormal noise;
※Strict environmental protection requirements, many greases have not passed relevant environmental certification; ……
Solution:
※ As the lubricating grease will dry out after a period of time, it is necessary to select lubricating grease made of high-grade precision base oil and precise process;
※ For bearing fatigue peeling, the selected base oil has high viscosity, the formed oil film is thick and not easy to penetrate;
※ Add rust inhibitors and antioxidants to the grease to provide rust, rust and aging resistance of the grease;
※ For abnormal bearing noise, strictly control the production process, purify the production environment, and ensure that the grease is pollution-free;
※ In response to the requirements of the current market, all automotive products must meet environmental protection requirements…
Simulation bench test:
Basic introduction:
※ The test bench can perform durability tests on bearings of models 608, 6201, 6204, and 6303.
※ Four sets of bearings can be tested simultaneously in each experiment. The maximum speed of the test machine is 30,000 rpm. It can simulate both normal temperature tests and high temperature (up to 180°C) tests.
※The bearing can be loaded radially (up to 5000N) and axially (up to 2000N).
