Purpose:The primary purpose of this lab is to comprehend a number of things about gear reducers in general. This might be the importance of gear ratios as well as gear trains, the procedure that goes into selecting a speed reducer, and the importance of a differential gear system. Along with that, we will learn why gear reducers can also be called speed reducers.Procedure: In Exercise one, we are given a gear train with 6 separate gears and tasked with recording their gear type, number of teeth, pitch diameter, diametral pitch, and gear ratio. Then, we use the job master trainer to run the drive at 3 separate speeds. We are asked to record the speed in rpm on the driven sprocket, as well as the end shaft. After recording these times, we are tasked with calculating the actual and theoretical speed ratios for each gear pair in the drive. In Part B, we use the Morse PT-93 catalog to select a speed reducer based on the criteria and information givenin the problem. After, we are asked to find the service factor, torque, drive ratio, required
