Description

Technical Field

[0001] The utility model relates to the technical field of motor shafts, in particular to a motor and a motor shaft with high reliability. Background Art

[0002] The motor shaft is the most important shaft in the motor, usually referring to the shaft of the motor rotor. It is mainly responsible for outputting the power of the motor to the load. In the electric motor, this shaft plays the role of transmitting power, so it is also called the motor output shaft. It is worth noting that the spindle motor is usually an AC motor. In some applications, the motor shaft may also output power through a gear transmission system. In this case, the motor shaft may be the output shaft after gear transmission. In short, the motor shaft is a key component in the motor that outputs rotational motion and torque to other mechanical parts.

[0003] When existing motors are used in some specific scenarios, it is necessary to extend the axial length of the motor shaft. Therefore, a component for extending the motor shaft is usually installed on the motor shaft. However, during use, the motor shaft component deflects and loosens due to vibration, causing rotation damage and creating a major safety hazard. In addition, the existing motors do not have an additional mechanism to support the motor shaft. Since the motor shaft component is added, the axial length of the motor shaft is longer, which may cause the motor shaft to vibrate or shake when rotating, causing the insulating material and bearings inside the motor to be under additional pressure, accelerating their wear and aging, which is not conducive to the long-term use of the motor and the motor shaft.
