Motor shaft bearing lubrication and seal

Motor shaft even bearing lubrication and sealing specific what are the requirements? Below is detailed to introduce for you: because the water pump shaft bearings of high speed, cooling condition is bad, but there is high demand for leak grease, waterproof and, therefore, water pump shaft bearings with radial touch rubber seal structure. Figure 4 - 4 for three types of sealing ring structure diagram. Figure 4 - 4 a for lips structure, the main lip longer to avoid water immersion bearings, another lip to avoid oil leakage. Figure 4 - 4 b for enhanced lips structure, the main lip with oscillation. For engines and caused by imbalance of revolving oscillations of the environment. Figure 4 - 4 c for three lip structure, stainless steel ring profile is U. Cover retaining ring is tight on the shaft and shaft rotate together, its original owner lip and third lip with radial touching, waterproof shows two quarter, improve the reliability of the seal. And because rubber and stainless steel smooth touch friction small, delay the abrasion of the sealing surface, and then increase the durability of the seal. China bearing industry standard rules: bearing manufacturer shall be carried out regularly water pump shaft bearing seal function and temperature rise test, should ensure that grease leakage is beyond 5%, the temperature rise is not beyond 60 degrees.
