摘要
针对传统往复锯锯齿下料机构,提出了一种新型的端曲面齿轮副弧形切割往复锯运动机构。利用端曲面齿轮副啮合及坐标变换原理,并结合机械原理、齿轮啮合理论与现代设计方法,建立了端曲面齿轮副-连杆复合运动机构的传动坐标系,推导了该复合机构的运动方程,分析了弧形切割往复锯复合运动机构的位移、速度和加速度等的影响及其变化规律。采用SolidWorks和Adams软件,建立了弧形切割往复锯运动仿真模型,获得了该往复锯的仿真运动特性规律。搭建相应的实验台并进行测试,将理论仿真数据和实验结果分别与理论分析结果进行了对比分析,验证了端曲面齿轮副弧形切割往复锯机构的可行性。
Aiming at the sawtooth cutting mechanism of traditional reciprocating saw, a new type of kinematic mechanism of arc cutting reciprocating saw with curve face gear pair is proposed. By using the meshing and coordinate transformation principle of curve face gear pair, and combining with mechanical principle, gear meshing theory and modern design method, the transmission coordinate system of the compound kinematic mechanism with curve face gear pair and connecting rod is established, the motion equation of the compound kinematic mechanism is deduced, the influence of displacement, velocity and acceleration on the compound kinematic mechanism of arc cutting reciprocating saw and its variation law are analyzed. By using the software of SolidWorks and Adams, the kinematic simulation model of the arc cutting reciprocating saw is established, the kinematic characteristic law of the reciprocating saw is obtained. The corresponding experimental bench is built and tested, and the theoretical simulation data and experimental results are compared with the theoretical analysis results to verify the feasibility of the reciprocating saw mechanism with curved gear pair at the end. The corresponding experimental bench is built and the test is carried out, and the theoretical simulation data and experimental results are compared with the theoretical analysis results, the feasibility of the arc cutting reciprocating saw mechanism with curve face gear pair is verified.
