| Summary: | Considered the cam-roller allowable pressure angle condition <italic>α</italic><sub>1</sub>≤[<italic>α</italic><sub>1</sub>] and the linkage-rocker allowable pressure angle condition <italic>α</italic><sub>2</sub>≤[<italic>α</italic><sub>2</sub>]， the special class-Ⅱ mechanisms synthesis task of disc cam mechanisms with roller follower in planar general motion is further explored. Through the kinematic and force analysis of the research object， the condition of <italic>α</italic><sub>2</sub>≤[<italic>α</italic><sub>2</sub>] is transformed into the solution interval of the three force intersection， a new concepts of "instantaneous nested interval of three force intersection" is put forward. Then， three cases of "instantaneous nested interval of three force intersection" are discussed and the solution steps of the most compact mechanism satisfying the condition of double allowable pressure angles are given. Finally， the special class-Ⅱ mechanisms synthesis task of disc cam mechanisms with roller follower in planar general motion is solved satisfactorily. |
