TECHNICAL FIELD

[0001] The application belongs to the field of power transmission devices, and particularly relates to a high-wear-resistance electric rotating shaft structure. BACKGROUND

[0002] In the field of power transmission, the electric rotating shaft structure plays a crucial role as a key part of the circuit breaker driving system. Through the rotation of the rotating shaft driven by the power source, the dynamic contact and the static contact are combined or separated to realize the connection or disconnection of the power line, thereby controlling the transmission and interruption of electric energy. This rotating shaft structure plays an indispensable role in the automation and intelligentization process of the power grid, and has important significance for improving the operation efficiency and safety of the power grid. However, in actual application, the electric rotating shaft structure is often gradually worn out due to friction and wear during continuous rotation. Especially in the power transmission system, due to large current and heavy load, the rotating shaft needs to withstand huge mechanical stress and thermal stress, making the wear and strength problems more prominent. Once the rotating shaft is severely worn or unstable, it will not only affect its normal rotation, but also may cause power transmission interruption, equipment failure and even safety accidents and other serious consequences. Therefore, it is necessary to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0013] The second avoiding slot is communicated with the first avoiding slot and the axial direction of the second avoiding slot is perpendicular to the axial direction of the first avoiding slot.

[0014] Optionally, at least two mounting holes are formed on the body part.

[0015] Optionally, all the mounting holes are symmetrically arranged about the axial direction of the second avoiding slot.

[0016] Optionally, an arc-shaped bridge part is formed on the body part.
