AI Technical Summary
In helical drive components, the clearance between the inner and outer helices is difficult to control, leading to unstable power transmission and potentially causing vibration and swaying. This can affect the reliability and safety of the system, especially in applications sensitive to external disturbances, such as photovoltaic tracking systems.
Design a transmission nut, including an elastic element, a first nut, and a second nut. Through a combination structure of a straight guide and a connecting strip, the first nut and the second nut can be automatically adjusted to ensure a tight fit. Through the fixed connection between the transmission element and the side ring, synchronous movement can be achieved, reducing jamming or locking phenomena and improving transmission accuracy and stability.
The transmission nut fits tightly with external components, improving transmission accuracy and operational stability, enhancing the integration and operating efficiency of the screw drive assembly, preventing jamming, ensuring the stability and reliability of the equipment, and adapting to the screw fit relationship within the transmission sleeve.
