Description

Technical Field

[0001] The utility model relates to the technical field of motor shafts, and more specifically to a wear-resistant motor shaft. Background Art

[0002] The motor shaft is the component that carries and transmits rotational force within the motor. Its primary function is to transfer the motor's rotational force to the load, but it can also transmit other forces. The motor shaft must be strong enough to withstand the torque output by the motor and the load's moment to prevent damage. The stiffness of the motor shaft determines the vibration levels during operation. A high-stiffness motor shaft can effectively reduce vibration and noise, improving the smoothness of the motor's operation. The fatigue life of the motor shaft is directly related to the motor's service life. Proper material selection and design can extend the life of the motor shaft. Motor shafts are typically made of high-quality steel or alloy materials with high strength and wear resistance.

[0003] As shown in the prior art of publication number CN211579777U, although this prior art facilitates the assembly of multiple sets of rotating shafts by providing limit blocks and slots, thereby extending the combined length of the rotating shafts and enhancing the range of use of the device, in this prior art, when the first and second rotating shafts are assembled and spliced, there is a misalignment at the splicing point, which affects the subsequent assembly of the rotating shafts.

[0025] When in use, the staff places the extension shaft 2 in front of the main shaft 1 installed on the motor, and makes the connecting shaft 5 and the clamping plate 9 correspond to the connecting groove 7 and the clamping groove 8 respectively. Then, the connecting shaft 5 is rotated through the through hole 10 to connect with the connecting groove 7, so that the extension shaft 2 and the main shaft 1 can be connected as one. At the same time, the clamping plate 9 is embedded in the clamping groove 8. By engaging the clamping plate 9 with the clamping groove 8, the extension shaft 2 can keep consistent with the movement of the main shaft 1, and the assembly of the main shaft 1 and the extension shaft 2 is tighter, and there will be no unevenness.

[0026] In order to facilitate the staff to operate the operating ring 6, Figure 1-5 As shown, a plurality of through holes 10 are provided on one side of the annular groove 4 corresponding to the front end exterior of the main shaft 1 and the front end exterior of the extended shaft 2.
