- An offset type of follower in which the motion follower is along an axis from the axis of the cam center.arrow_forwardThe diagram shows a stepped-cone pulley system used on some pillar drills. The belt is arranged on the four different steps of the cone pulley to obtain different speeds. The cone pulley has four steps (A, B, C & D). Another cone pulley having four steps (E, F, G and H) is placed parallel to the spindle cone pulley. Both the cone pulleys are connected by a flat or V belt. The belt can be arranged between the steps “A & H”, “B & G”, “C & F” and “D & E”. The cone pulley at the bottom is connected to the electric motor by a V-belt. (Lower pulley is the driver pulley, and the upper pulley is the driven pulley). The diameters of the pulleys are given in the following table.arrow_forwardWhat kind of Multiple repetitive cycle is show on scheme below?
