Consider a simple gear train having odd number of idler gears. The direction of motion of the driven gear will
In simple gear train having odd number of ilder gears, the direction of motion of the driven gear will be same as that of the driving gear and vice- versa.
Consider a simple gear train consisting of three gear wheels with 20, 15 and 40 teeth respectively. The velocity ratio of third wheel to first wheel would be
If in a gear trains, the first wheel is a driver and the last wheel is a driven then train value is defined as the
The reciprocal of the speed ratio (or velocity ratio) is known as train value of gear train.
A gear train, in which atleast one of the gear axes is in motion relative to the frame, is known as
Match List-I with List-ll and select the correct answer using the code given below the lists:
A. Compound gear train
B. Epicyciic spur gear train
C. Worm and worm wheel gear train
D. Epicyciic bevel gear train
1. Automobile gear box
2. Automatic transmission of automobile
3. Speed reducer for lifts
4. Automobile differentials
In a simple gear train, if the number of idle gears is odd, then the motion of driven gear will
The speed ratio and the train value, in a simple train of gears, is independent of the size and number of intermediate gears. These intermediate gears are called idle gears, as they do not affect the speed ratio or train value of the system.
The gear train usually employed in clocks is
In reverted gear train, first and last gear is on the same axis such an arrangement has application on speed reducers, clocks and machine tools.
A reverted gear train is one in which the output shaft and input shaft
If the axes of the first and the last wheel of a compound gear coincide, it is called a reverted gear train.
Train value of a gear train is
