Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, in particular to a waterproof device for a drainage roller bearing of a quenching machine. Background Art

[0002] In industrial production, quenching machines are widely used in the heat treatment process of metal materials. The quenching process requires high temperature and rapid cooling, so a drainage system is needed to discharge the cooling medium in time to ensure the quality of the workpiece and production efficiency. However, during the quenching process, the drainage roller bearing is easily corroded by water, which leads to rust, increased wear and even damage to the bearing, thus affecting production operation and product quality.

[0003] At present, most roller conveyor waterproof devices are integrated with roller conveyors to prevent the bearings of each conveyor roller in the external drainage roller conveyor from being corroded by water. During use, they cannot meet the waterproof requirements of conveyor rollers of different sizes and are inconvenient to disassemble and install.

[0004] Therefore, the utility model provides a waterproof device for a quenching machine drainage roller bearing to solve the problems raised in the above background technology. Utility Model Content
