Question

For the cam-follower type mechanism in the figure, the movement program is as follows:

LOW DWELL (Rest or Stop) for 45 °
Elevation 4mm at 135 °
HIGH DWELL (Rest or stop) for 45 °
Drop or drop 4mm at 135 °
If the base radius is 27 mm, how much is L2 in mm if θ2 = 201 degrees?

وا YA Х 03 ON O2 L2

Answer 1

Detailed answer of above asked question is solved as below.

Given Or: 1350 D movement program low dwell Elevation / Rise High dwell = h = 450 drop 01 = 1350 lift of follower = 5= 4 mm base radius of cam= r6 = 27 mm > Displacement diagrom. of Pollower Assume that follower move with uniform velocity during rise & drop scale Yaxis: 1cm = 0 lmm. xaxis = 1cm= 30° $y-axis. Displacement is) S= 4 mm 보 0.A x-axis By = 135 e = 1350 45 angle of displacement @= 2.010 ad La As we seen above, lift of the followen displacement of follower at q=2100 is S2, From above diagram measurement S₂ = 5= 4 mm Shar L2 = Sztro lift aut 2010 = displacement at 2012 + baseradios of cam L₂ = 4+27 L₂ = 31 mm at O₂ = 2010
