SYNTHESIS OF GUIDED chain drive MECHANISM WITH LINKAGE

Chinese Journal of Mechanical Engineering 1998年第1期11卷 76-81页

作者： Shan, Baozhong Wu, Keyong Wang, Yixing Chen, Entao Changchun Inst of Optics and Fine Mechanics Changchun China

A method of designing guided chain drive mechanism with linkage basing on the given motion track is expounded. The method consists of two steps that are synthesizing four bar linkage approximately first and then deducing guide track, removing crank and jointing free end with chain. An example of synthesis that can realize the given motion track precisely is provided.

Optimum Determination of Partial Transmission Ratios of Mechanical driven Systems Using a chain drive and a Two-step Helical Gearbox

引用

Journal of Environmental Science and Engineering(B) 2017年第2期6卷 80-83页

作者： Vu Ngoc Pi Tran Thi Phuong Thao Dang Anh Tuan Mechanical Engineering Faculty Thai Nguyen University of Technology Thai Nguyen 250000 Vietnam

This paper presents a study on optimum determination of partial ratios of mechanical drive systems using a chain drive and two-step helical gearbox for getting minimum size of the system. The chosen objective function was the cross section dimension of the system. In solving the optimization problem, the design equation for pitting resistance of a gear set was investigated and equations on moment equilibrium condition of a mechanic system including a chain drive and two helical gear units and their regular resistance condition were analyses. From the results of the study, effective formulas for determination of the partial ratios of the chain drive and two-step helical gearboxes were introduced. As the formulas are explicit, the partial ratios can be calculated accurately and simply.

Roller Screw and Threaded chain Speed Reducer: An Experimental Evaluation

引用

Modern Mechanical Engineering 2024年第1期14卷 1-11页

作者： Filiberto Gutiérrez Instituto de Ingeniería Universidad Nacional Autónoma de México Mexico City Mexico

We are developing a speed reducer that can be considered a transformation of a worm gear reducer: the worm is replaced by an inverted roller screw, and the gear is replaced by a threaded chain drive. This configuration lessens wear, increases load capacity, and improves efficiency. The threaded chain consists of nut-shaped links. This paper presents the results of tests carried out on a prototype with a reduction ratio of 46.
