Drive illustrates kinematics of a basic three-dimensional cam drive. Cam Mechanism Drive illustrates conversion of rotation into oscillation at right angles. Arrangement illustrates positive constraint of forward and return motion without the use of a return spring. Lever Mechanism Drive illustrates conversion of continuous rotation into continuous rotation with a varying speed ratio. Pin on drive crank engaged eccentric, slotted link, impairing variable speed.
Eccentricity is adjustable.
Indicator on output shaft assists in studying speed variation and effect of eccentricity on motion of drive. Indicators on the four shafts illustrate speeds, phasing and directions of rotation gear transmissions. Gear Drive Drive illustrates principle of angular-speed variation using change gears. Drive shaft connected by a sliding clutch to any one of a set of change gears connected to output shaft, thus providing a choice of speed ratios. Useful in understanding design principles and kinematics of transmissions, such as are found in machine tools and vehicle drives.
