The Test of a Cam with a Translating Follower Having an Added Ternary-Roller Intermediate Link

To design this cam, the outer cam profile is obtained by compensating the single-roller cam profile. Then, the center point of the second roller and the contact point of the cam are obtained by the superposition method, and the center point of the third roller and the contact point of the cam are obtained by the geometric condition of the follower, and then the inner cam profile is obtained. Dimensions: 75 * 77 * 24 (mm^3) Output curve: 12 mm stroke, rise 120°, dwell 60°, fall 120°, dwell 60° Contact plane clearance: 0.15 mm 要設計此凸輪，需先得出單滾子凸輪輪廓進行補償得到外凸輪輪廓。接著利用疊代方法得出第二滾子的中心點與凸輪接觸點，再利用從動件的幾何條件得出第三滾子的中心點與凸輪接觸點， 進而得到內凸輪輪廓。 尺寸：75 * 77 * 24 (mm^3) 輸出曲線：從動件行程 12 mm，凸輪位移 50 mm 120° 升程，60° 暫停，120° 降程，60° 暫停。 接觸面間隙：0.15 mm Youtube: https://youtu.be/BD_yyinvlg4
