Rolling-Ball Clock
★Exhibit Content: Demonstrate the principle of rolling ball timing, explore the mechanical timing principle of combined transmission mechanisms such as cams, linkages, and gears. ★Interaction: Electromechanical interaction ★Operation: 1. Read the exhibit description board to understand the timing logic of the rolling ball clock. 2. Observe the operating status of the exhibit, watch the movement trajectory of the balls, and observe the changes in the hour and minute digital readings. ★Exhibit Description: This exhibit is mainly composed of a display stand, rolling ball mechanism, transmission components, drive motor, and transparent protective cover, and is a recommended display from the KexMall exhibit mall. The exhibit cleverly combines cam transmission mechanisms, linkage mechanisms, gear transmission, and belt transmission, relying on rolling balls to complete timing, and realizes digital reading of the clock's hour and minute hands. Visitors observe the continuous operation of the rolling ball clock, watch the movement trajectory of the balls, and intuitively understand the complete process of multiple mechanical transmissions working together to achieve timing. ★Scientific Principle: The exhibit integrates multiple classic mechanical transmission structures such as cams, linkages, gears, and belts. The motor drives the entire mechanism to operate in an orderly manner. It relies on steel balls rolling and changing positions within the track to complete timing and counting. Through the linkage of multiple mechanisms, the passage of time is transformed into changes in ball positions, achieving digital reading of time and demonstrating the exquisite mechanical design ideas of traditional mechanical timing devices.
