For those application scenarios that require high load and high frequency start-stop, the stability, durability, and maintenance convenience of traditional motor shafts have certain limitations. In order to improve the adaptability of the motor shaft under complex working conditions, reduce the maintenance frequency, and prolong the service life, more and more innovative designs are being applied to the improvement of the motor shaft.

[0004] Therefore, it has become an important demand for the development of motor technology to develop a motor shaft with good disassembly, capable of absorbing vibration and impact, and suitable for high load and high frequency start-stop working environment. The split type motor shaft provided by the utility model innovates in view of the above problems, which can effectively improve the working efficiency and stability of the motor shaft, reduce the maintenance difficulty and cost, and has important practical application value. SUMMARY

[0006] The motor shaft of the utility model is mainly composed of a spindle body, a jaw head, a coupler and a flexible block group, the structure of each part is closely matched, and can be disassembled, maintained and replaced, with excellent adaptability and operational convenience.

[0007] The spindle body is the core part of the motor shaft, carrying the power transmission of the entire motor. Several permanent magnet blocks are embedded on its surface for generating a stable magnetic field to ensure the working efficiency of the motor. The arrangement design of permanent magnet blocks can effectively improve the power output and stability of the motor.

[0008] The claw head is fixedly installed at both ends of the main shaft body and is mainly connected with the main shaft body through a connecting device to realize stable connection.

[0009] The adapter is a part of the motor shaft connected with external equipment or load shaft. The surface of the adapter is provided with a shaft hole for connecting with the output shaft. The adapter is connected with the claw head through the meshing groove and the claw tooth key to ensure reliable and tight connection and realize stable power transmission.

[0010] The flexible block group is located between the claw head and the adapter and is mainly composed of a positioning ring and a tooth separation lobe. The tooth separation lobe is located inside the meshing groove and is in contact with the claw tooth key on the surface of the claw head and the adapter. The tooth separation lobe is made of high-elastic rubber material and can effectively absorb vibration and impact during transmission, reduce mechanical wear and tear and improve the durability of the motor shaft.

[0011] Through the above technical scheme, the utility model has the following beneficial effects:

[0012] All components of the utility model are designed to be detachably connected, especially the claw head, the adapter and the flexible block group. This design can greatly simplify the installation and disassembly process of the motor shaft, making maintenance and replacement more convenient. The tooth separation lobe is in interference abutment with the surface of the claw head and the adapter to ensure the fastening and stability of the connecting components.

[0013] The motor shaft of the utility model is rationally designed and all components are tightly matched, which not only improves the overall mechanical strength but also effectively avoids damage caused by mechanical vibration, impact and other factors. Especially in a high-load and high-frequency starting working environment, the motor shaft shows good running stability and long service life.

[0014] Since the motor shaft of the utility model adopts a detachable connection structure, disassembly and maintenance become more convenient, reducing downtime and labor costs caused by unnecessary disassembly during production and maintenance. In addition, the flexible block group can effectively reduce vibration and impact during work, which helps to prolong the service life of the motor shaft and other related components, thereby reducing the frequency of maintenance and replacement and further reducing maintenance costs.
