Publication number: 20230147034Abstract: A transmission mechanism includes: a main shaft, a power input member, a gear component, and a one-way transmission component. The gear component is arranged on the main shaft. The one-way transmission component is sleeved on the main shaft. The one-way transmission component is connected with the power input member and the gear component. The one-way transmission component enables the gear component to perform one-way transmission under the action of the power input member. The gear component is connected with a power output member in a transmission way to change a rotation speed transmitted from the power input member to the power output member. The power input member performs reciprocating motion with the main shaft as an axis to drive the power output member to move. By arranging the one-way transmission component, the transmission mechanism can perform arc reciprocating motion, thereby improving transmission efficiency.Type: ApplicationFiled: January 6, 2023Publication date: May 11, 2023Applicant: SHENZHEN NANBO AUTOMATION EQUIPMENT CO., LTDInventor: Liyuan LUO
