1results about How to "Start and stop smoothly" patented technology

This utility model discloses a reciprocating motion drive structure for a transport trolley, including a track and a frame. The frame is movably mounted above the track, and a rolling assembly with rollers at its bottom supports the frame and allows it to move on the track. A transmission assembly is mounted on the frame to drive the frame to reciprocate on the track. This transmission assembly includes a synchronous pulley driven by a motor, a transition pulley pivotally mounted on the frame, and a synchronous belt. The two ends of the synchronous belt are fixed to connecting plates at both ends of the track. The transition pulleys are distributed on both sides of the synchronous pulley, and the synchronous belt is wound around the transition pulleys and the synchronous pulley. When the motor drives the synchronous pulley to rotate, the synchronous belt, in conjunction with the transition pulleys, drives the frame to reciprocate on the track. By replacing direct drive with synchronous belt transmission, and relying on the meshing of the synchronous belt teeth and the fixing at both ends, the start-stop impact can be effectively buffered, and slippage errors can be eliminated, resulting in smooth start-stop and high positioning accuracy.
