Advantages of gear drive

Gear drive is used to transmitting mechanical power from one place to another, often used to convey power to wheels of the bicycle and motorcycles. It is also used in a wide variety of machine apart from the vehicle. Let us have a deep insight into the advantages of gear drive in this article. 

Advantages of gear drive :

  • It is very compact and needs less space.
  • Most convenient for very small centre distances.
  • The velocity ratio will remain constant throughout and any velocity ratio up to 60:1 can be obtained.
  • It has very high efficiency which is very useful in transmitting motion.
  • It will be possible to transmit the power if the axes of the shafts are not only parallel, but even when the axis of the shaft is nonparallel, intersecting, non-intersecting and coplanar or non-coplanar by using different types of gears.
  • They can be used conveniently for transmission of low, medium and high power.
  • It is a reliable service that is a very good advantage.
  • Gears are employed for a wide range of applications like in watches, precision measuring instruments, machine tools, gearboxes fitted in automobiles, aero engines, etc.
  • Gears may be cast integral with the shafts if required. 
  • In a wide range of metallic and non-metallic materials, gears can be cast.
  • It provides a large range of speed and torque for same input power. 
  • It is compact and needs less space.
