Description

Technical Field

[0001] The utility model relates to the technical field of motor shafts, in particular to a split-type servo motor shaft. Background Art

[0002] A split servo motor shaft is a design in which the motor and shaft are mounted separately rather than integrated together. This design is often used in applications that require greater customization and flexibility because it allows the user to choose different motor and shaft combinations as needed. A split servo motor shaft usually consists of a servo motor, a reducer, an encoder, and a connecting shaft. This design makes maintenance and replacement of parts more convenient, and also makes it easier to adapt the system to different application requirements. Split servo motor shafts are common in fields such as automated machinery, robotics, medical equipment, and industrial production lines. Their flexibility and customizability make them an ideal choice in many applications.

[0003] At present, many motor shafts are usually connected to the motor through threads, but under the action of mechanical load, especially in high torque and high vibration environments, the threads may gradually loosen. The loose threaded connection will cause the transmission efficiency between the motor and the shaft to decrease, and there may be losses when transmitting power and torque; therefore, it does not meet the existing needs. For this reason, we propose a split servo motor shaft. Utility Model Content
