Definitions
- the present invention relates to a cold-resistant seal suitable for a hub bearing of an automobile, that is, a bearing sealing device and a rolling bearing with a cold-resistant sealing device.
- the hub of an automobile is an important part in terms of the function of connecting the spindle that serves as the axle and the rotating wheel, and the structure of the hub body also includes a bearing (for the inside) and an oil seal. Assemble the bearing (for the outside) and plate washer and insert them into the spindle.
- the rubber used for bearing seals, etc. is a rubber that has excellent elasticity and good sealing properties. Rubber is gradually cured when used at low temperatures, such as outdoors in winter. As a result, the followability with the contact surface is also weakened, and the sealing performance is also reduced, so that foreign matter intrudes or dies leaks.
- the cold resistance of rubber cannot be measured only at the glass transition point (Tg), and is largely related to the free movement of rubber molecules. Therefore, when the cohesion between molecules is strong (the polarity is large) ), The motility of the rubber molecules is poor and the flexibility is impaired. Even in the same tali-tolyl butadiene rubber (NBR), the content of acrylic-tolyl is reduced even in hydrocarbon rubbers containing tolyl groups. The higher the rubber, the worse the cold resistance.
- NBR tali-tolyl butadiene rubber
