MEMOTo: Dylan SmithFrom: Cindy NguyenSection: 907Date: 10/24/16Re: Lab 7 GearsPurpose: 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 areused 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.
