According to information from the National Intellectual Property Administration, Jiangsu Dena Precision Bearing Co., Ltd. has been granted a patent entitled ‘A Bearing Ring Cleaning Device’, with authorisation announcement number CN224358962U, filed in May 2025.
The patent abstract states that this utility model discloses a bearing ring cleaning device in the field of cleaning machinery. It comprises a cleaning tank with a connecting block fixedly mounted on its inner wall; a sliding support plate is fixedly mounted at the upper end of the connecting block; a slider is slidably engaged within the open guide rail of the sliding support plate; the lower end of the slider is slidably connected to a guide rail worm wheel; a worm shaft meshes with the gear below the guide rail worm wheel; a fixing column is fixedly connected to the central aperture in the worm wheel disc, and this fixing column is fixedly installed at the centre of the bottom of the cleaning tank; a rotating rod is fixedly installed in the aperture on the upper end of the sliding support plate; a movable brush rod is slidably mounted within the open-ended guide rail of the rotating rod; the upper end of the rotating rod is fixedly connected to Motor No. 1, which is in turn fixedly mounted on a motor mounting bracket. This utility model achieves the fixation of the bearing ring by manually placing it into the centre of the sliding support plate, utilising the engagement of the rotating rod with the central groove of the sliding support plate, and driving the movement of the worm gear via Motor No. 2, thereby preventing the bearing ring from falling out.
