Drive illustrates conversion of rotation into oscillation using a four-bar linkage. Crank-operated driving shaft and driven shaft (with indicator) coupled by floating link, length of which is adjustable. Center distance between shafts also adjustable. Useful in studying speed relationships and effect of dimensional changes on motion characteristics of a non-uniform motion drive. Price: $43.89
Mechanism illustrates conversion of continuous rotation into continuous, non-uniform rotation by means of a four-bar linkage. Center distance and length of coupler link adjustable. Unit useful in studying speed relationships and method of construction permitting unobstructed movement of linkage. Price: $38.68
Drive illustrates conversion of rotation into oscillation by means of a crank driving an eccentric, slotted link. Eccentricity is adjustable. Device useful in studying speed variation and effect of eccentricity on motion characteristics of drive. Price: $43.89
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. Price: $38.68
Drive illustrates the simultaneous drive of three cranks to keep the rotation of the driven shafts in step with the driving shaft. Indicators on all shafts are useful in studying the velocity and directions of rotation. Price: $52.27
This mechanism, frequently called "Watt's Epicyclic Gear Drive", consists of a 30 tooth planet gear riding externally on a 54 tooth sun gear. The motion of the planet is coupled by connecting rod to the slider. Study of the displacement of the slider is aided by a linear scale mounted on the unit. Price: $54.36
Drive illustrates one of a class of drives which convert rotary motion into reciprocating motion. The output motion of the slider is harmonic and therefore this drive is frequently employed when it is necessary to generate the sine function of the angle of the crank in mechanical systems. Price: $41.82
Drive when used in conjunction with #51 illustrates the increased displacement of the slide when the slot of the scotch yoke is at an angle with the axis of the slider. As in #51, the motion of the slider describes the function of the sine of the driving crank angle. Price: $41.82
Five piece kit consisting of two screw drives and three wrenches. Price: $12.95 |
