Advantages Of Compound Gear Train. The compound epicyclic gear train in fig.1 is taken from bhel and the parameters are altered for the optimization purposes. Compound gear trains are used when large changes in speed or power output are needed and there is only a small space between the input and output shafts.
Simple Gear Train Shaft Each Shaft In A Simple Gear Train Is Attached To One Spur Gear Only. - Ppt Video Online Download from slideplayer.com
They offer constant velocity ratio. The axis of shaft on which the gear are mounted may move relative to the fixed axis. Advantages of epicyclic gearbox :
The Advantages Of Epicyclic Gear Trains Are Higher Torque Capacity, Lower Weight, Small Size And Improved Efficiency Of The Planetary Design.
The gear 2 and gear 3 is mounted on a same shaft so they rotate in a same speed and same direction the main purpose of the reverted gear train it is the first and the last it means the driver gear and driven gear is same direction. And every gear being attached to different shaft. They offer constant velocity ratio.
In This Gear There Is More Than One Gear On The Shaft Which Is Rigidly Fix And Mashed With The Gear On Another Shaft Forming Gear Train.
The axis of shaft on which the gear are mounted may move relative to the fixed axis. Gears are mechanically strong, so higher loads can be lifted. Introduction applications types of gear train introduction to compound gear train equation derivation for compound gear train.
Gears Are Used For Transmission Of Large H.f.
Compound gear trains allows to achieve higher gear ratios without having the need for more number of shafts. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping; They are useful to cover large distances;
When Two Gears Share A Shaft They Have The Same Gear Ratio.
As the weigh is 60%, and half the size of a conventional gear. Compound gear train •for large velocities, compound arrangement is preferred •two or more gears may rotate about a single axis. They could also be used to change the axis of input and output shafts say when they are perpendicular etc… reverted gear trains are a type of compound gear trains where the input and the output shafts are co axial or parallely offset.
Compound Gear Trains Are Used When Large Changes In Speed Or Power Output.
This provides a smooth transmission of rotation from one gear to the next. A spur gear is more efficient if you compare it with helical gear of same size. Compound gear trains are used when large changes in speed or power output are needed and there is only a small space between the input and output shafts.
