Chain and Sprocket systems Chain and sprocket systems use a chain to transmit rotary motion from the driver to the driven shaft. Sprocket is the name of the gear when it use a chain. The mechanism of the bicycle is a typical example
Chain and Sprocket systems You can use the formula of the gears for this mechanism. It's the same. n1. Z1 = n2. Z2 n1: sprocket 1 speed Z1: sprocket 1 teeth n2: sprocket 2 speed Z2: sprocket 2 teeth
Worm gear Another way of making large speed reductions is to use a worm gear.You can think of the worm as if it were a gear with 1 tooth.
Watch out Worm gear. Watch out You can use the formula of the gears for this mechanism. It's the same. n1. 1 = n2. Z2 n1: screw 1 speed n2: gear 2 speed Z2: gear 2 teeth
Rack and Pinion Systems. Rack and pinion systems involve changes between rotary and linear motion.
