Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to a bearing drying device. Background Art

[0002] The bearing mainly includes an outer ring, an inner ring, a steel ball and a sealing ring. The processing procedures of the bearing mainly include assembly, inspection, lubrication, cleaning and drying. After the bearing is lubricated and cleaned, it needs to be dried. The drying process is mainly completed in a drying box.

[0003] In the prior art, the purpose of drying is generally achieved by evaporating the moisture on the surface of the bearing by hot air, or by using infrared radiation to evaporate the moisture inside the bearing. However, most drying devices for bearing production do not have the function of rotating the bearing, which results in that only one part of the bearing is heated each time, and the part far away from the heat source cannot be heated well, resulting in uneven heating. In addition, the inner ring of the bearing is not convenient to be heated, resulting in poor drying of the inner ring of the bearing, which may lead to inconsistent drying degrees of the inner and outer rings of the bearing. This will cause a difference in humidity between the inner and outer rings of the bearing, thereby affecting the overall performance and life of the bearing, and a large amount of moisture may remain inside. This moisture will gradually evaporate during the use of the bearing, generating bubbles or causing corrosion, causing damage to the bearing, so a bearing drying device is proposed to solve the above problems.
