What are the applications of epicyclic gear train?
A gear train is made when a combination of gears in mesh are used to transmit motion. A frequent application of epicyclic gear trains is accomplishing a large speed reduction in a small space. A planetary or epicyclic gear train is one type of gear train used to transmit motion.
What are the applications of reverted gear train?
The reverted gear trains are used in automotive transmissions, lathe back gears, industrial speed reducers, and in clocks (where the minute and hour hand shafts are co-axial).
Where the epicyclic gear trains are used Mcq?
The epicyclic gear trains are useful for transmitting high-velocity ratios with gears of moderate size in a comparatively lesser space. The epicyclic gear trains are used in the back gear of lathe, differential gears of the automobiles, hoists, pulley blocks, wrist-watches, etc.
What are different types of gear train and its application?
Following are the different types of gear trains: Simple gear train. Compound gear trains. Reverted gear trains. Epicyclic gear trains.
What are the applications of gears?
Application of Gears
| Type of gear | Application |
|---|---|
| Helical gear | Similar to spur gears but with greater loads and higher speeds. Automobiles (transmission systems) |
| Rack and pinion | Weighing scales Material handling and transfer systems Railways and trains Automobiles (steering systems) |
Which gear train is used in clock?
Reverted gear train
Reverted gear train: When the axes of the first gear and the last gear are co-axial, then the gear train is known as a reverted gear train. The reverted gear trains are used in automotive transmissions, lathe back gears, industrial speed reducers, and in clocks (where the minute and hour hand shafts are co-axial).
Which gear train is used in automobile?
Planetary gear train (PGT) has been widely used in the transmissions of helicopters, automobiles, wind turbine, aircraft engines, etc. The main advantages of this transmission are its high efficiency, its compactness, its large transmission ratio and its large power-to-weight ratio, etc.
What are the application of gear?
Application of Gears
| Type of gear | Application |
|---|---|
| Bevel gear | Pumps Power plants Material handling systems Aerospace and aircrafts Railways and trains Automobiles |
| Helical gear | Similar to spur gears but with greater loads and higher speeds. Automobiles (transmission systems) |
What is a two stage gear train?
A two-stage gear train uses two single-stages in series. Figure 2.3 represents the basic form of an external gear two-stage gear train. Let the first gear in the first stage be the driver. Then the speed ratio of the two-stage gear train is : Speed Ratio i = z2 / z1 X Z4 / Z3 = n1 / n2 x n3 / n4 (2.3)
What are the uses of gear?
Gears are used to transfer motion and torque between machine components in mechanical devices. Depending on the design and construction of the gear pair employed, gears can change the direction of movement and/or increase the output speed or torque.
