- Traction Drive
Drive illustrates principle of positive-motion transmission between parallel shafts using chains. Sprocket on crank-operated drive shaft actuates roller chain passing over intermediate (idler) sprocket and engaging sprocket on driven shaft (with indicator). Useful in showing speeds and directional relationships in chain drives. Price: $75.26
Drive illustrates principles of motion transmission over belts. Introduction to friction drives. Crank-operated drive shaft with pulley drives belt running over intermediate (idler) pulley and pulley on driven shaft with indicator. Useful in illustrating speed and directional relationships in belt drives. Price: $57.51
Drive illustrates principle of variable-speed transmissions using belt drives. Drive shaft and driven shaft contain five pulleys each; center distance is adjustable. Different reduction ratios obtainable by running belt over different pulley combinations. Unit useful in studying speeds and constructional requirements in variable speed drives. Price: $78.41
Drive illustrates principle of belt drives used for uniform motion transmission between parallel shafts. Crank-operated drive shaft has pulley driving belt passing over pulley on output shaft. Indicator on output shaft useful in studying speeds and directions of rotation in a basic friction drive. Price: $55.42
Unit illustrates design of open belt drives in tandem. Crank-operated drive shaft with driving pulley engages belt running over pulley on intermediate shaft. Second pulley on intermediate shaft drives output shaft through another belt. Indicators on the three shafts useful in studying speeds, phasing and directions of rotations involved. Price: $62.72
Drive illustrates principle of positive motion transmission between parallel shafts using a toothed belt. Crank-operated drive shaft with grooved pulley drives grooved (timing) belt, which in turn drives grooved pulley on output shaft. Indicator on output shaft useful in studying timing, speeds and directions of rotation involved. Price: $55.42
Drive illustrates principle of constant-ratio motion transmission between parallel shafts by means of frictional contact between two wheels or discs. Crank-operated drive shaft with disc bears on second disc on output shaft. Basic speed relationships clarified with aid of indicator on output shaft. Price: $47.04
Five piece kit consisting of two screw drives and three wrenches. Price: $12.95 |
