GEAR TRAIN
GEAR TRAIN.pptx (Size: 452.3 KB / Downloads: 27) Gear Train. Combination of two or more gears when they made to mesh each other to transmit power from one shaft to another. Classification according to the position of axes of the shafts. Parallel Intersecting Non-intersecting and non-parallel The two parallel and co-planar shafts connected by gears are called spur gear and this arrangement is known as spur gearing. These gears are parallel to the axis of the wheel. Another name given to the spur gearing is helical gearing, in which the teeth are inclined to the axis45°. According to the type of gearing External gearing Internal gearing Rack and Pinion In external gearing, the gears of the two shafts mesh externally with each other. The larger of these two wheels is called spur wheel and the smaller wheel is called pinion. In an external gearing, the motion of the two wheels is always unlike. Compound Gear train For large velocities ratios, compound gear train arrangement is preferred. The velocity of each tooth on A and B are the same so: A tA = B tB -as they are simple gears. Likewise for C and D, C tC = D tD. APPLICATIONS Gear drive used where transmission of exact power is needed. In gear box of vehicles In lathe machines In clocks, watches In almost all machines |
