碩士 / 崑山科技大學 / 機械工程研究所 / 91 / A flexible rapier drive mechanism is a device for driving gearwheel that can rotate back and forth with large angle to control the movement of gripper carrying straps of weft insertion members in the shed of shuttle less weaving loom. The purpose of this work is to use the method of type synthesis and design criteria to obtain new and feasible rapier mechanisms. First, this work described the compositions of rapier mechanism and presented the design requirements of the exiting design.
Based on the design requirement, we synthesis new rapier mechanisms with two loops. Additionally, the number of links of thee designed mechanisms is less than five. When the maximum peak value of acceleration of weft insertion members is large, the loom will break.
The author designs an input speed function to reduce the maximum peak value of acceleration. The deigned speed function also reduces the dynamic characteristics. Finally, we derive the kinematic and dynamic analysis for a variable-speed rapier mechanism to prove the feasibility of provided theory.
