Description

Technical Field

[0001] The utility model relates to the technical field of fan repair, in particular to a tool for disassembling a fan impeller. Background Art

[0002] The fan is a commonly used mechanical equipment, which is widely used in various factories. Due to the wide range of applications of fans, in some special fields, such as the steel mill finishing rolling main drive motor, the motor winding is cooled by air cooling. Due to the harsh operating environment, the fan impeller is often damaged or corroded. In order to ensure the normal operation of the fan, the impeller needs to be replaced.

[0003] The impeller of the fan is usually directly installed on the motor shaft. The existing method of removing the fan impeller is usually three people using three crowbars to find relatively evenly spaced positions and use leverage to pull the fan impeller off the shaft. This is not only time-consuming and labor-intensive, but also easy to damage other parts of the fan; and once the support position deviates or the force is uneven, it is very easy to cause the crowbar to fly out, causing personal injury accidents.
