Kennedy Grimes IDIS 303-909 Memo To: Raghuram Krishnan From: Kennedy Grimes Section #: 909 Date: 3/7/18 Re: Lab 6: GEAR TRAINS AND SPEED REDUCERS Purpose: The purpose of this lab was to further our knowledge of various speed reducers and gear trains. Speed reducers adjust the speed between motors and the actual driven part. Gear trains adjust the gear ratios for various types of gears, so that this adjustment may take place in a fairly small setup. Procedure: We observed and recorded various measurements and characteristics of different gears. We also recorded various RPM’s and velocity ratios at various speeds using the Job Master Trainer. We then used the PT-93 catalog to calculate various measurements, including service factor and drive ratio, for a selected worm gear speed reducer. Results: The results are in the packet attached. Conclusions/Recommendations: This lab furthered my understanding of how gear ratios have the ability to affect the output. Each gear has advantages and disadvantages, of which the numbers reflected according, which we were able to observe and understand more thoroughly. This also furthered my understanding on how to calculate pitch diameter and teeth for various gears. Being hands-on allowed us to see human error first hand and differentiate tangible benefits for a gear train or speed reducer.
