TLF ID L2375
Choose a pair of gears to drive a conveyor belt to an oven, including cases where the belt gear is larger than the driver gear. Notice that the number of rotations for each gear depends on the gear size (number of teeth). Identify the relationship between the number of teeth and the number of rotations. Choose a combination of two gears to adjust the speed of the conveyor belt. For example, choose a gear size (96 teeth) that will rotate three quarters of a turn for every turn of the driver gear (72 teeth). This learning object is the last in a series of six objects that progressively increase in difficulty.
