Description

Technical Field

[0001] The utility model relates to the technical field of carton sealing machine maintenance, in particular to a bearing disassembly device. Background Art

[0002] Bearings are often used in mechanical equipment to install shafts or rollers. After long-term operation of mechanical equipment, the bearings are severely worn and need to be replaced. Especially for mechanical equipment with high precision requirements, bearing replacement frequency is more frequent.

[0003] In actual production, there are two transmission shafts in the main box of the carton sealing machine that reciprocate up and down. The linear bearings are installed in the main box, and the bottom is limited by a retaining ring. The main box is about 50mm above the ground. When the linear bearing is damaged and needs to be repaired and replaced, due to the small space where the bearing is located, common tools (such as retaining ring pliers) cannot directly reach into the limited space to disassemble the bearing. It is often necessary to additionally disassemble the wall panel of the equipment, turn over the main box, and then disassemble the bearing, which adds unnecessary workload, resulting in longer maintenance time and increased labor intensity for the staff.
