MORE CAMS -POSSIBLE ANSWERS

As the pear shaped cam rotates, the arm of the model remains in the same position for at least 180 degrees. Then it rises and drops slowly, following the profile of the cam. This makes the model look as if he is raising and lowering the flowers.

 

As the drop cam rotates the model’s arm remains at the same height for some time. Then it begins to rise slowly until it suddenly drops down. This makes the model look as if the axe is being used in a ‘chopping’ action.

     

 

     

 

As the swash cam rotates the followers move up and down alternately. The swash cam operates like a ‘spinning top’. The followers move the arms of the model up and down as if it is waving.

 

As the handle is turned the shafts rotate. As the shaft rotates the eccentric cams also rotate moving the individual segments of the model up or down. The movement is smooth and at a uniform speed.
