Description

Technical Field

[0001] The utility model relates to the technical field of ceramic bearings, in particular to a ceramic bearing with a dustproof structure. Background Art

[0002] Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubrication, high speed, etc. Most of the existing ceramic bearings are open-type structures. When in use, the rollers are exposed, and dust can easily enter the bearings and affect the rollers, which can easily affect the use of the bearings;

[0003] According to the Chinese patent announcement number: CN217814581U, a bearing with a dustproof structure is disclosed. The reinforcement block can increase the installation stability of the dustproof sealing plate by fixing the adhesive layer when in use, and can prevent the dustproof sealing plate from falling off during use. The stability is relatively high. The dust-absorbing adhesive layer can improve the dust-proof effect of the dustproof sealing plate when in use, and can directly adsorb and stick the floating dust on the dust-absorbing adhesive layer to prevent dust from entering the bearing. The protective cotton ring can store the lubricating oil through the groove when in use, which is convenient for oil supply to the bearing and can ensure the lubrication effect of the bearing for a long time. The effect of use is better than that of the traditional method. In this technical solution, the dustproof sealing plate is adhered to the bearing by a fixed adhesive layer, which makes it very laborious to disassemble it, and after disassembly, glue may remain on the bearing, thereby affecting the normal use of the bearing. For this reason, we propose a ceramic bearing with a dustproof structure. Utility Model Content
