Bearing seal lip contact contact area

Sealing ring with no clearance between shaft, said contact seal, seal lip contact contact area is larger, the better sealing effect, but allows the shaft speed is smaller, on the contrary.

1. The first is the study of test and screening of deep groove ball bearing seal structure and develop corresponding imported bearing inner ring seal groove structure, the current SKF 6205 Bearings [url removed, login to view] seal structure upgrading.

2. After the analysis, the main reason is that the current seal design structure is unreasonable, inner ring without seal groove, plus the manufacturing accuracy is not high reason. INA imported bearing seal technology in China, therefore, the future development trend is: represented by import deep groove ball INA bearings, sealing technology experiment.

3. Import bearings and use different structure, different working conditions for sealing ring structure and material is different, so the research and development workload is very big.

4. From single sealing lip to the sealing lip, from contact seal developed non-contact seal, etc.; Looked from the product type, the ball there are both imported bearing, roller bearing. Follow the international development trend in our country, also developed import deep groove ball bearings with seals.

5. With the development of the industry, food industry, in particular, the popularity of the modern office machinery and electrical appliances, equipment design is compact, the weight to prevent leaks, gas leakage, it appears INA imported bearing itself with imported bearings of the sealing device.

6. To control the heating temperature appropriate, high temperature damage about the imported bearing, temperature is low enough ring expansion, the effect is not significant. 80 ~ 1000 ℃ heating temperature of the thermal expansion of the inner ring diameter, this with the general INA of the over surplus quantity of the imported bearing, is enough.

7. The need to control the heating temperature, the general will import bearing heated to 80 ℃, 100 ℃. It is enough. More than 120 ℃ tempering occur will lead to import bearings, causing lower lower hardness and precision of the ring.
