摘要

本文研究二階減速機之不同傳動方式，分析減速機運轉過程中其零件的運動與應力狀態，如果設計不當會造成動力不平衡與應力集中現象。基於相同減速比的設計，我們提出傳統設計、新型1設計、新型2設計、RV設計和漸開線串連設計多種不同結構之二階減速機。傳統設計結構是由兩組一階減速機使用串聯方式組成，其組裝零件較多，輸出方式由輸出件作輸出動力。新型1設計之柱銷零件，其以凸輪對和插銷方式連接兩階擺線輪，兩階擺線輪之齒輪數不同，輸出方式由針輪作輸出動力。新型2設計零件中的中心圓盤，其以凸輪對方式對稱連接兩階擺線輪，兩階擺線輪之齒輪數不同，輸出方式由針輪作輸出動力。RV設計是由漸開線減速機與擺線減速機串連組成。漸開線串聯設計結構是由兩組一階減速機使用串聯方式組成。本文探討多種不同結構之二階減速機建立其系統動力分析模型，本模型可分析主要零件的運動及應力變化情形，根據分析結果，最後討論多種設計在傳動上的差異。

This paper studies different transmission method of two-stage speed reducer, analyzes the components' motion and stress conditions during the speed reducer in operation, and the dynamic load imbalance and stress concentration phenomena caused by improper design. Based on the design of identical speed reducing ratio, we propose manifold different structured two-stage speed reducers as Traditional design, New 1 design, New 2 design, RV design and Involute series design. The Traditional design structure is assembled by series connection of two one-stage speed reducers, requires more assembled components, output is done by output parts to output power. The pin component of New 1 design uses cam pair and pin to connects two-stage cycloidal gears, with different number of teeth of two-stage cycloidal gears, output is done by ring gear to output power. The center disc component of New 2 design uses cam pair symmetrically connects two-stage cycloid gears, with different number of teeth of two-sage cycloidal gears, output is done by ring gear to output power. RV design is assembled by series connection of Involute reducers and Cycloid reducers. Involute series design structure is assembled by series connection of two one-stage speed reducers. This paper explores manifold different structural types of two-stage speed reducer, establishes their system dynamics analysis model, and uses the model to analyze main components' motion and stress variation conditions, and based on the analysis results to discuss the differences of transmission on manifold designs.
