This chapter will dis-cuss the kinematics of gear tooth theory, gear types, and the kinematic design of gearsets and Gear Trains. We call a set of two or more gears meshed together a gear train. They often consist of multiple gears in the train Gear trains are multiple sets of gears meshing together to deliver power and motion more effectively than can be accomplished by one set of gears. Gear trains are multiple sets of gears meshing together to deliver power and motion more effectively than can be accomplished by one set of gears Third gear ratio = × =Since, is closer to then, therefore, tC =and tD =The top gear requires direct connection between input GEAR TRAINS A gear train is two or more gear working together by meshing their teeth and turning each other in a system to generate power and speed. A gear train is, therefore, a kinematic chain in which motion is transmitted by gears. Some of the reasons to use gear trains to transmit motion are: (a) Space restrictions. Abstract. ChapterGear Trains. Figureshows the various types of gears that can be used in a gear train. A gear train is, therefore, a kinematic chain in which motion is transmitted by Some are listed in the bibliography at the end of this chapter. To create large gear ratio, gears are connected together to form gear trains. We call a set of two or more gears meshed together a gear train. Gears 4 In a compound train of gears, as shown in Fig., the gearis the driving gear mounted on shaft A, gearsandare compound gears which are mounted on shaft B. The gearsandare also compound gears which are mounted on shaft C and the gearis the driven gear mounted on shaft D. Let N cuss the kinematics of gear tooth theory, gear types, and the kinematic design of gearsets and gear trains of simple, compound, reverted, and epicyclic types. When motion has to be transmitted between two axles that are far apart GEAR TRAINS A gear train is two or more gear working together by meshing their teeth and turning each other in a system to generate power and speed. It reduces speed and FigCompound gear train. Gearsandcan be either spur or helicalgears and are mounted on parallel shafts. It reduces speed and increases torque. Examples of the use of these devices will be presented as well Abstract. Chain and belt drives will also be discussed.
