Conclusions:
After completing this lab, we left with a greater understanding of how to identify a gear or
sprocket using given nomenclature as well as its specifications.
Real World Applications:
Real world applications include various things from bicycle chains and conveyor belts.

Chains
Introduction:
In this lab, we endeavored to understand the use of chains with sprockets to transmit power and
torque.
Methodology:
Exercise IA:
Given a type of chain and an example of nomenclature, identify its pitch, roller diameter, inside
width, and plate thickness.
Exercise IB:
Given a sprocket’s nomenclature, give the manufacturer, ID number, sprocket type, pitch,
number of teeth, bore diameter, bottom diameter, sprocket width, maximum hub diameter, and
pitch diameter.
Exercise II:
Use the chain drive on the Parker trainer. Record the chain number, sprocket driver number,
sprocket driven number, number of teeth on driver, number of teeth on driven, and the central
distance. Then, on three different speed settings, find the actual driver speed, actual driven
speed, actual velocity ratio, and theoretical velocity ratio.
