Description
The mechanism is used to determine the product sin(α)*(1/cos(β)) When cam 1 is turned about fixed axis D-D through the angle α, follower 2 is displaced a distance proportional to sin(α), and roller a, carried by follower 2, rolls along the guide of channel member 3. At this, member 3 moves parallel to itself displacing slide 4, connected to member 3 by a pivot at point A, a distance proportional to sin(α). The contour (working surface) of cam 5 is designed so that when it is turned about fixed axis E-E through angle β, follower 6 is displaced a distance proportional to 1/cos(β). At this, channel member 3 turns about axis B of follower 2 and displaces slide 4 a distance proportional to 1/cos(β), When both cams, 1 and 5, are turned, slide 4 is displaced in one of the directions shown by the arrows a distance proportional to 1 the product sin(α)*( 1/cos(β)). $3201$CmL,MO$
