Description

Technical Field

[0001] The utility model relates to the technical field of magnetic levitation motors, in particular to a disassembly and assembly tool for a magnetic levitation motor rotor locking nut. Background Art

[0002] As an advanced electric motor technology, the magnetic levitation motor achieves contactless transmission and suspended operation by relying on the unique magnetic levitation principle. Its own manufacturing process requirements are very strict. The frictionless and lubrication-free characteristics bring about lossless power transmission, zero friction and minimized mechanical loss. The reason why the magnetic levitation motor can exert higher efficiency than other motors is inseparable from its own protection characteristics. The magnetic levitation motor is equipped with a protective bearing to protect the magnetic bearing during the operation of the motor and prevent the motor from falling due to external factors, thereby causing damage to itself. The adjustment of the total protective gap requires the help of a locking nut.

[0003] At present, most manufacturers directly use basic tools such as screwdrivers, wrenches, and rubber hammers to disassemble and assemble locking nuts. Generally, they are loosened with basic tools first and then disassembled manually. However, during the loosening process, strong force is often required, which can easily damage the top screw holes on the locking nuts. It is time-consuming and labor-intensive, and the disassembly and assembly effect is very poor. Utility Model Content

[0026] Reference Figure 3 、 Figure 4 The positioning pin 6 includes a screw 8 and a pin 9. The external thread of the screw 8 is spirally matched with the internal thread set on the inner side of the positioning hole 5. The screw 8 is screwed into the positioning hole 5. The screw 8 is connected to the pin 9 and the length of the pin 9 extending out of the wrench body 1 is adjusted by rotating the screw 8.
