Do you know the production technology of sealed cylindrical roller bearings?

At present, the sealed cylindrical roller bearings used are usually open bearings, that is, the bearings do not have a sealing structure, and the cylindrical rollers are directly exposed to the production and processing environment, and dust, water vapor or impurities in the environment during production and use. Harmful substances such as foreign matter easily enter the inside of the sealed cylindrical roller bearings structure, which tends to cause the wear of the cylindrical roller to be intensified, increase the friction between the cylindrical roller and the inner ring and the outer ring, affect the production efficiency, and affect the service life of the bearing, while the sealed cylindrical roller bearings is in the process of rotation. In the middle, the lubricating oil between the roller and the inner ring and the outer ring is easy to pull out the sealed cylindrical roller bearings due to the centrifugal action of the rotation, which greatly reduces the lubrication performance of the sealed cylindrical roller bearings, and at present, in order to realize the convenient installation of the sealed cylindrical roller bearings, it is usually designed on the inner ring side.

Conducive to the angle of inclination of the roller and the inner ring, it is more likely to cause leakage of lubricating oil, which is not conducive to the normal operation of the sealed cylindrical roller bearings. There is a cylindrical roller bearing with a seal on the market, including an inner ring, an outer ring and a rolling body assembled between the inner and outer rings through a cage, and supporting the axial sides between the inner ring and the outer ring. The skeleton and the sealing lip are connected to the side wall of the outer ring at one end, and the sealing lip is in contact with the side wall of the inner ring. There are certain defects in sealing in this way. As mentioned above, the inner ring generally has an inclination angle due to the fact that The inner ring has a slope, and the closer to the distal end of the inner ring slope during the working process of the sealed cylindrical roller bearings, the worse the adhesion effect of the sealing lip, thereby affecting the sealing effect, and the external impurities easily enter the internal structure of the sealed cylindrical roller bearings.

Technical realization ideas of sealed cylindrical roller bearings
In view of the deficiencies of the prior art, the present technology provides a sealed cylindrical roller bearings, the structure is simple, practical and reasonable, and the sealing of the single row cylindrical roller bearing is effectively realized. The present technology provides a sealed cylindrical roller bearing, comprising an inner ring, an outer ring and a rolling body assembled between the inner and outer rings through a retainer, the inner ring having an inner ring raceway and an inner ring rolling The bevel on both sides of the road, the axial side between the inner ring and the outer ring is mounted with a sealing assembly, the sealing assembly comprises a supporting skeleton and a sealing rubber attached to the outer peripheral surface of the supporting frame.

Technical Protection Point of sealed cylindrical roller bearings
A sealed cylindrical roller bearings, comprising an inner ring, an outer ring and a rolling body assembled between the inner and outer rings through a retainer, wherein the outer ring is provided with an inner ring raceway and is arranged on both sides of the inner ring raceway The inclined surface is characterized in that: the sealing member is mounted on both sides of the axial direction between the inner ring and the outer ring, and the sealing assembly comprises a supporting frame and a sealing rubber attached to the outer peripheral surface of the supporting frame, the supporting skeleton cross section The support frame includes a ring-shaped left frame and a ring-shaped right frame, and the ring-shaped left frame and the ring-shaped right-frame root are connected by a connecting frame, and the inner ring slope surface is provided with a mounting groove for fixing the support frame. The annular left skeleton and the annular right skeleton top are provided with a sealing lip, and the sealing lip is in contact with the outer ring raceway and constitutes a double sealing fit.
