Lab 7 Gears
Purpose:
The primary objective of this lab is to understand the working of gears through simple
experiments.
Procedure:
Students identified different gears using a catalog and searched for aspects of the gear such
as the pitch, number of teeth, pressure angle, part number etc. With a list of driver and
driven gears students calculated the speed ratio, safe HP and maximum torque. In the
second exercise given certain qualifications that had to be fulfilled, students determined the
necessary gears required for the problem.
Results:
The results for the labs are enclosed in the attached forms.
Conclusions/Recommendations:
Gears are one of the oldest forms of power transmission mechanisms. They are used to
change speed, direction of rotation and power transmitted similar to belts and chains but are
used in environments where belts and chains can’t. There are many forms of gears that have
varying diameters, number of teeth, angles, etc. and each of these variables have different
applications. This lab shows students the different types of gears and what functions they
provide.
