AI Technical Summary
In existing slip ring designs, brushes are prone to loosening or falling off due to factors such as vibration, wear, temperature changes, and mechanical impact, leading to poor contact or disconnection and affecting the stability of equipment operation.
Multiple guide rods and ball bearings are used to connect to the conductive ring of the rotor tube section. Pressure springs and limiting sleeves are used to maintain contact, ensuring that the balls always fit against the outer wall of the conductive ring when the equipment shakes. A stable connection is ensured by arc-shaped metal connecting pieces and multiple guide rods.
This reduces the likelihood of poor contact and disconnection caused by equipment shaking, thus improving the stability of equipment operation.
