Description
TECHNICAL FIELD
[0001] The utility model relates to a double shaft rotation technical field, especially a double shaft rotation structure. BACKGROUND
[0002] In the field of modern machinery and electronic equipment, the double shaft rotation structure is widely used in various products due to its unique flexibility and adaptability. Gear meshing rotation plays an important role in the double shaft rotation structure. In many industrial automation devices, such as double shaft linkage machining centers, two transmission shafts are meshed with each other through high-precision gears to achieve extremely precise synchronous rotation, ensuring that the cutter performs complex trajectory processing on the workpiece. Due to the close meshing relationship between the gears, not only can stable torque be transmitted, but also the speed and direction of the double shaft can be flexibly changed according to the gear ratio, thereby meeting various work requirements.
[0003] However, the existing double shaft rotation structure mainly based on gear meshing rotation has obvious limitations when the device is in a non-rotating state. When the device stops running, only the tooth side gap between the gears, the tooth surface friction, and the inertia of the mechanical structure itself can maintain the current position. Once subjected to external vibration, impact, or accidental touch, the gears are prone to slight displacement, which in turn causes the double shaft position to deviate.
[0004] Therefore, there is a need for a double shaft rotation structure. SUMMARY
