Geometric design method of lightweight line gear mechanism
Yangzhi Chen, Xiaoxiao Ping, Zhen Chen, Yu Zhang, Maoxi Zheng, Qinsong Zhang
Izvirni znanstveni članek
Oznake: lightweight design;space curve meshing;gear design;kinematics experiments;high transmission ratio;
Based on the space curve meshing theory, a lightweight line gear mechanism (LLGM) was proposed in this paper. The LLGM can achieve the objective of lightweight design by reducing the radial dimension of the gear, which has an improvement in terms of size reduction. The outstanding advantage of the L ...
